The urban trees when not follow the proper principles of planting and management, transforms the trees into nesting sites and feeding termites. Thus, arboreal species of termites begin to assume increasing importance as pests. This study aimed to identify the species of termites associated with tree species and verify, under field conditions, if these termites exhibit preference for nesting and foraging, in the sandbank area of Catalan Island, in the municipality of Rio de Janeiro, RJ. For this, 95 were chosen randomly planting rows of trees located in this area. These lines has traveled a path of 100 m, also randomly chosen, and during that route all the trees were inspected to verify the occurrence of termites. Termites found were collected, preserved in 70% alcohol for later identification. To assess the preferred nesting, all the trees were inspected for the presence nests of N. corniger. The occurrence of termites was registered in all tree rows sampled (n = 95). Of the total of 545 inspected trees, 77% were infested by termites, identified four species distributed into two families: three native species Termitidae (Nasutitermes corniger Motschulsky, Nasutitermes jaraguae Holmgren and Microcerotermes strunckii Soerensen) and an exotic species of Rhinotermitidae (Coptotermes gestroi Wasmann). The most frequent species was N. corniger (?2 = 82.04, df = 3, p <0.001), occurring in 79% of infested trees, followed by N. jaraguae (6% of infested trees). The termite species least infested trees were found in C. gestroi (1%) and M. strunckii (1%). In general , the exotic tree species Albizia Lebeck is the most infested by termites and also exotic Leucaena leucocephala is less infested. 114 Nest establishment of N. corniger were identified, and the tree species Schinus terebinthifolius the most nidificada. So the trees of the Catalan's Island salt marsh area are infested with native and exotic termites, however, the native termite N. corniger is predominant. / Os t?rmitas arbor?colas que fazem parte da fauna brasileira atacam ?reas urbanas que expandiram sobre ?reas de vegeta??o silvestre. A arboriza??o urbana quando n?o segue os preceitos adequados de plantio e manejo, transforma as ?rvores em locais de nidifica??o e alimenta??o dos cupins. Dessa forma, esp?cies arbor?colas de cupins passam a assumir import?ncia crescente como pragas. Esse estudo objetivou identificar as esp?cies de cupins associadas a esp?cies arb?reas e verificar, em condi??es de campo, se esses t?rmitas exibem prefer?ncia para nidifica??o e forrageamento, na ?rea de restinga da Ilha do Catal?o, no munic?pio do Rio de Janeiro, RJ. Para isso, foram sorteadas aleatoriamente 95 linhas de plantio de ?rvores localizadas nessa ?rea. Nestas linhas foi percorrido um trajeto de 100 m, tamb?m escolhido aleatoriamente, e durante esse percurso todas as ?rvores foram inspecionadas para verificar a ocorr?ncia de cupins. Os cupins encontrados foram coletados, preservados em ?lcool 70% para posterior identifica??o. Para avaliar a prefer?ncia de nidifica??o, todas as ?rvores foram inspecionadas quanto a presen?a de ninhos de N. corniger. A ocorr?ncia de t?rmitas foi registrada em todas as linhas de plantio amostradas (n=95). Do total de 545 ?rvores inspecionadas, 77% estavam infestadas por cupins, sendo identificadas quatro esp?cies distribu?das em duas fam?lias: tr?s esp?cies nativas de Termitidae (Nasutitermes corniger Motschulsky, Nasutitermes jaraguae Holmgren e Microcerotermes strunckii Soerensen) e uma esp?cie ex?tica de Rhinotermitidae (Coptotermes gestroi Wasmann). A esp?cie mais frequente foi N. corniger (?2 =82,04; g.l.=3; p<0,001), ocorrendo em 79% das ?rvores infestadas, seguida por N. jaraguae (6% das ?rvores infestadas). As esp?cies de t?rmitas menos encontradas nas ?rvores infestadas foram C. gestroi (1%) e M. strunckii (1%). De maneira geral, a esp?cie arb?rea ex?tica Albizia lebeck ? a mais infestada pelos t?rmitas e a tamb?m ex?tica Leucaena leucocephala ? a menos infestada. Foram identificadas 114 nidifica??es de N. corniger, sendo a esp?cie arb?rea Schimus terebinthifolius a mais nidificada. Portanto, as ?rvores da ?rea de restinga da Ilha do Catal?o s?o infestadas por t?rmitas nativos e ex?ticos, no entanto, o t?rmita nativo N. corniger ? predominante

The aims of this study were to analyze how banana plantations affect bats assemblages, to check whether the planting of bananas causes a decrease in the dispersion of seeds, to verify if the abundance of nutritional resources have some influence on bat abundance and richness in areas of banana plantation, to verify if bats move between plantations and forest fragments or if they show site fidelity to the areas. A total of 12 banana plantations in Rio de Janeiro State were sampled. Each month, from November 2008 to October 2010, two capture nights were conducted, being one night in a banana plantation area and another in an adjacent forest fragment. Bats were sampled with mist nets, totaling 142,560 m2.h of sampling effort. Bats were identified, marked, remained in cloth bags to obtain fecal samples, and released after it. The seeds obtained in fecal samples were counted and classified. The availability of food resources in banana plantation areas was estimated in five 100 m2 plots, where the number of banana trees, flowers and fruits was counted. A total of 2,369 captures and recaptures of bats of 27 species were recorded. In banana plantations 22 species were recorded (four of which were exclusive to such habitat), and in fragments 23 (with five exclusive). The capture frequency was higher in plantations than in fragments. Richness, diversity and evenness were similar between habitats. Artibeus lituratus, Carollia perspicillata, Glossophaga soricina and Phyllostomus hastatus were more abundant in the banana plantations. The abundance of frugivores, nectarivores and omnivores was higher in plantation areas while insectivores were more abundant in forest areas. The estimated richness for each environment suggests that forest fragments are richer than the banana plantations. A non-metric multidimensional scaling (NMDS) indicated separation between banana plantations and forest fragments based on species abundance, using Braycurtis similarity. We analyzed 1,127 fecal samples from 20 species that had 33 morphotypes of seeds of 12 plant families. There was presence of banana pulp in fecal samples from 10 species. The richness and abundance of seeds dispersed in the two environments did not differ, however the abundance of seeds per fecal sample was lower in banana plantations. The abundance of Sturnira lilium was correlated negatively with the abundance of banana and fruits. The abundance of G. soricina, A. lituratus, nectarivorous and frugivorous bats showed positive relationship with the abundance of food resource. We obtained 102 recaptures of 99 individuals of 10 species. The most recaptured species were C. perspicillata, A. lituratus and P. hastatus. Twenty-eight individuals moved between environments, 68 remained in the same environment of the capture. In all analyzed cases, the proportion of individuals recaptured in the same location of capture was higher than the recapture proportion in different environments. These results reinforce the potential of bats as regenerators in habitats modified by humans, since banana plantations maintain a diverse assemblage. The ability of bats to disperse pioneer plants species and the use of different environments assure that nature services of forest regeneration are continued / A modifica??o da paisagem para a produ??o de alimentos e outras comodidades para consumo humano representa a mais severa e comum amea?a ? biodiversidade global. Os objetivos deste trabalho foram analisar como o plantio de bananas afeta a comunidade de morcegos, analisar se o plantio de bananas diminui a dispers?o de sementes, verificar se a abund?ncia de recurso alimentar influencia a abund?ncia e a riqueza de morcegos em ?reas de planta??o de banana, verificar se os morcegos se deslocam entre ?reas de planta??es e fragmentos florestais e se mant?m fidelidade ? ?rea de captura. Foram selecionadas 12 ?reas de planta??o do estado do Rio de Janeiro. Mensalmente, entre novembro de 2008 e outubro de 2010, foram realizadas duas noites de coleta, sendo uma em ?rea de planta??o de banana e outra em um fragmento florestal adjacente. As coletas foram realizadas com redes de neblina, totalizando 142.560 m2.h de esfor?o amostral. Os morcegos foram identificados, permaneceram em sacos de pano para obten??o de amostras fecais, e soltos ap?s receberem marca??o. No laborat?rio, as sementes foram classificadas em morfotipos e contadas. A disponibilidade de recurso alimentar nas ?reas de planta??o de banana foi estimada atrav?s de cinco plots de 100 m2 , nos quais era contabilizado o n?mero de bananeiras, infrutesc?ncias e infloresc?ncias de banana. Um total de 2.369 capturas e recapturas de 27 esp?cies foi registrado. Nos bananais, foram capturadas 22 esp?cies, sendo quatro exclusivas; nos fragmentos, 23, sendo cinco exclusivas. A frequ?ncia de captura nos bananais foi maior do que nos fragmentos. A riqueza, a diversidade e a equitabilidade mostraram-se similares. As esp?cies significativamente mais abundantes nos bananais foram Artibeus lituratus, Carollia perspicillata, Glossophaga soricina e Phyllostomus hastatus. A abund?ncia de frug?voros, nectar?voros e on?voros foi maior em ?reas de plantio, enquanto a de inset?voros foi maior em ?reas de floresta. A riqueza estimada para cada ambiente sugere que os fragmentos florestais s?o mais ricos do que as ?reas de plantio. Uma an?lise de escalonamento multidimensional (NMDS) indicou separa??o entre os bananais e os fragmentos florestais baseado no n?mero de capturas por esp?cie, atrav?s da dist?ncia Bray-curtis. Foram analisadas 1.127 amostras fecais de 20 esp?cies, que apresentaram sementes de 33 morfotipos de 12 fam?lias de plantas. Foi poss?vel verificar a presen?a de polpa de banana em amostras fecais de 10 esp?cies. A riqueza e abund?ncia de sementes dispersadas nos dois ambientes n?o diferiram. No entanto, a abund?ncia de sementes por amostra fecal foi menor em ?reas de planta??o de banana. A abund?ncia de Sturnira lilium foi inversamente proporcional ? abund?ncia de bananeiras e infrutesc?ncias de banana. A abund?ncia de G. soricina, A. lituratus, morcegos nectar?voros e frug?voros foi diretamente proporcional ? abund?ncia de recurso alimentar. Foram obtidas 102 recapturas de 99 morcegos de 10 esp?cies. As esp?cies mais recapturadas foram C. perspicillata, A. lituratus e P. hastatus. Vinte e oito indiv?duos transitaram entre os ambientes, 68 permaneceram no mesmo ambiente da captura e tr?s foram recapturados duas vezes, uma em cada ambiente. Em todos os casos analisados, a propor??o de indiv?duos recapturados no mesmo local da captura foi maior do que a propor??o de indiv?duos recapturados em ambientes diferentes. Em ?reas de planta??o de banana, a ordem Chiroptera foi capaz de manter uma comunidade diversa, a capacidade de dispers?o de esp?cies pioneiras de plantas e a capacidade de deslocamento. Esses resultados refor?am o potencial dos morcegos como regeneradores de habitats modificados pelo homem.

Campus Salinas might understand and fixed knowledge. Aiming to verify how interdisciplinarity contributes to the development of students? learning through their own construction of knowledge due to their inclusion in the research project for developing the product ?pasteurized cane juice?. To evaluate the learning of each student individually, we used the method of the attitude constructing a questionnaire composed of 25 statements regarding the theoretical and practical knowledge on the production of pasteurized sugarcane juice. The questionnaire was administered to students at four different times: the first time (TI), considered as time zero, where the group of students responded to questionnaires when the teacher had not offered any information about the project and its related disciplines, the second time (TII), the students answered after watching an interdisciplinary exhibition project, the third time (TIII), responded after the production of juice, and the fourth and final time (TIV), where the group responded to questionnaires after the completion of analysis. Through this assessment it was revealed that the development of students? learning was significant and growing. They were also evaluated in relation to commitment to the proposed activities through: image registration, self-assessment of learning, development flowchart, and practice in the production of the juice and their laboratory tests. This other form of assessment showed differently the growth of these students during the research. They proved to be encouraged to work with the project because they could participate in activities that were not included in their daily profession. Through self-assessments, they show the desire to have an education focused on issues related to their reality, based on a curriculum in the various areas of knowledge can act in an integrated manner. And by working with flowchart, we could clearly see the development in relation to the production process of the cane juice. The work was very important in guiding the teacher to work other teaching methods both in the classroom, field or laboratory to stimulate the interest of the student of a pedagogical discipline. Students learn better and showed more satisfaction when they felt part of the learning process and not just passively receiving knowledge. / Esta pesquisa avaliou as contribui??es de se trabalhar com m?todo de projeto aplicado no processo de ensino-aprendizagem, almejando que os estudantes do Curso T?cnico em Agroind?stria do Instituto Federal do Norte de Minas Gerais ? Campus Salinas, compreendessem e solidificassem o conhecimento. Tendo como objetivo verificar como a interdisciplinaridade contribui para o desenvolvimento da aprendizagem dos discentes atrav?s da pr?pria constru??o do conhecimento devido ? sua inser??o no projeto de pesquisa para o desenvolvimento do produto ?suco de cana pasteurizado?. Para avaliar a aprendizagem desses alunos, utilizou-se o m?todo de atitude do indiv?duo construindo-se um question?rio composto de 25 afirmativas referentes aos conhecimentos te?ricos e pr?ticos relativos ? produ??o de suco de cana pasteurizado. O question?rio foi aplicado aos alunos em quatro momentos diferentes: o primeiro tempo (TI), considerado como tempo zero, onde o grupo de alunos respondeu aos question?rios quando o professor ainda n?o havia ofertado nenhuma informa??o sobre o projeto e suas disciplinas correlatas; o segundo tempo (TII), os alunos responderam ap?s assistirem a uma exposi??o interdisciplinar do projeto; o terceiro tempo (TIII), responderam ap?s a produ??o do suco; e o quarto e ?ltimo tempo (TIV), onde o grupo respondeu aos question?rios ap?s a conclus?o das an?lises. Atrav?s dessa avalia??o foi poss?vel perceber que o desenvolvimento da aprendizagem dos discentes foi crescente e significativo. Eles tamb?m foram avaliados em rela??o ao comprometimento com as atividades propostas atrav?s de: registro de imagens; auto-avalia??o da aprendizagem; desenvolvimento de fluxograma; e a pr?tica na produ??o do produto suco e suas an?lises laboratoriais. O registro de imagens foi outra forma de avalia??o que mostrou de uma maneira diferente o crescimento desses alunos durante a pesquisa. Eles mostraram-se estimulados ao trabalhar com projeto, pois puderam participar de atividades que n?o estavam inseridas em seu cotidiano escolar. Atrav?s das autoavalia??es, eles mostram a vontade de ter um ensino voltado para as quest?es relacionadas ? realidade deles, baseado em um curr?culo em que as diversas ?reas do conhecimento possam atuar de forma integrada. E atrav?s do trabalho com fluxograma, p?de-se perceber claramente o desenvolvimento com rela??o ao processo produtivo do suco de cana. O trabalho mostrou-se muito importante no sentido de orientar o professor a trabalhar outros m?todos de ensino tanto em sala de aula, campo ou laborat?rio para estimular o interesse do discente pela proposta pedag?gica de uma disciplina. Os estudantes aprenderam melhor e demonstraram maior satisfa??o quando se sentiram fazendo parte do processo de aprendizagem e n?o apenas recebendo os conhecimentos passivamente.

Federal Institute of Education, Science and technology of Pernambuco, focusing on ethnic-racial relations and reparations policies, recognition and appreciation of affirmative actions in everyday life at school. From the point of view of how to approach the problem, the search is qualitative descriptive character, having as a tool for field research to interview structured way. This study was born from the observation that there is a great difficulty to work with the contents that guide the theme of history and indigenous and Afro-Brazilian culture in the school context, as well as, ethnic-racial relations in the teaching-learning environment. To approach the theoretical reference was used the works of Kabengele Munanga, Maria Aparecida S. Bento, Lilia Moritz Schwarcz and Eliane Cavalleiro that inserts in the contemporary debate on the issues discussion-ethnic racial and their repercussions on relations between students and teachers in the school environment. The school, as A strategic area, has a key role in the process of construction and reconstruction of social values, so necessary if makes a new look on the racial issue in the school context, since the Brazilian education system is based on a Eurocentric vision, monoculture, discriminatory and exclusionary racist character. / A presente pesquisa tem o prop?sito de analisar as implica??es na implementa??o do Estudo da Hist?ria e Cultura Afro-Brasileiro e Ind?gena no contexto da educa??o b?sica e outros n?veis e modalidades de ensino, a partir das experi?ncias dos professores (as) e dos alunos (as) do curso t?cnico em agropecu?ria, integrado ao ensino m?dio, do Campus Barreiros - Instituto Federal de Educa??o, Ci?ncia e Tecnologia de Pernambuco, dando enfoque ?s rela??es ?tnico-raciais e as pol?ticas de repara??es, reconhecimento e valoriza??o de a??es afirmativas no cotidiano escolar.

This context is expressed in the significant speeches that subsidized the theme of this course, for example: (I hope that this course can empower me for the job market.) I believe that students will solve the lack of infrastructure, mechanization and technical assistance That we have in the area). Due to the need for a field education that is contextualized and compatible with the realities of the field, there is a need to develop teaching practices that value students' research, reasoning and way of life. In this way, this research aimed to develop, apply and evaluate the use of schematic maps (sketches) as pedagogical method, to understand the situation and relevance of protected territorial spaces defined in Law 12.651, particularly APP, within the perspective of Field Education and pedagogic alternation, via the generating theme. These procedures were carried out with a view to stimulating the production of theoretical and practical knowledge for a more concrete productive planning of the rural properties. Seventy students participated in this study, divided into two groups, participants and non-participants. The methodology used was action research, applying and evaluating the use of sketches as a teaching tool. The results show that, through the use of the sketches, the students visualized more clearly the main forms of use and occupation of the spaces of family property, identified the APP areas, applied knowledge of ecological processes and environmental legislation to the different situations. / O Campus Rural de Marab? (IFPA-CRMB) do Instituo Federal de Ci?ncias e Tecnologia do Par? (IFPA) oferece o Curso T?cnico em Agropecu?ria Integrado ao Ensino M?dio, baseado na pedagogia da altern?ncia, via tema gerador. Os estudantes deste curso est?o inseridos em um contexto regional de conflitos agr?rios e ao evidente incentivo ? pecu?ria como modelo de produ??o, tendo como consequ?ncias o desmatamento de ?reas de Preserva??o Permanente (APP). Este contexto apresenta-se expresso nas falas significativas que subsidiaram o tema gerador deste curso, a exemplo: (Espero que esse curso possa me capacitar para o mercado de trabalho. Acredito que os alunos v?o resolver a falta de infraestrutura, mecaniza??o e de assist?ncia t?cnica que temos na regi?o). Devido a necessidade de uma Educa??o do Campo contextualizada e compat?vel com realidades do campo, surge a necessidade de se desenvolver pr?ticas de ensino que valorizem a investiga??o, o racioc?nio e o modo de vida dos estudantes. Desta forma, esta pesquisa teve como objetivo desenvolver, aplicar e avaliar o uso de mapas esquem?ticos (croquis) como m?todo pedag?gico, para compreens?o da situa??o e relev?ncia de espa?os territoriais protegidos definidos na Lei 12.651, particularmente, APP, dentro da perspectiva da Educa??o do Campo e da altern?ncia pedag?gica, via tema gerador. Tais procedimentos foram realizados numa perspectiva de estimular a produ??o de conhecimentos te?ricos e pr?ticos para um planejamento produtivo mais concreto das propriedades rurais. Participaram desta pesquisa 70 estudantes, divididos em dois grupos, participantes e n?o participantes. A metodologia utilizada foi a pesquisa-a??o, aplicando e avaliando o uso dos croquis como instrumento de ensino. Os resultados apontam que atrav?s do uso dos croquis os estudantes visualizaram com mais clareza as principais formas de uso e ocupa??o dos espa?os da propriedade familiar, identificaram as ?reas de APP, aplicaram conhecimentos de processos ecol?gicos e de legisla??o ambiental ?s diversas situa??es.

Essa dissertação analisa a construção da história e da memória da Fábrica de Ferro de São João de Ipanema, na região de Sorocaba, a partir do referencial teórico de R.G. Collingwood, o qual formulou a conhecida história de cola e tesoura, com o intuito de questionar escritas da história ou práticas historiográficas em que seus autores apenas trabalham de maneira acrítica com relatos já produzidos, recortados de fontes disponíveis ao pesquisador e selecionados a partir de operações de lógica formal: informações recorrentes no mesmo sentido são colados no texto e as informações discordantes são selecionadas, descartando-se a supostamente errada ou inexata. Além disso, também se usou a distinção entre memória, memória coletiva, história e esquecimento, presentes, sobretudo, nos trabalhos de Maurice Halbwachs Paul Ricoeur, bem como as noções de progresso e da historia magistra vitae, que aparecem sobretudo nos relatos produzidos no século XX. Esta Fábrica, que foi uma dos primeiros empreendimentos industriais do Brasil, cuja origem remonta ao século XVI, despertou o interesse de várias personalidades, como Pedro Taques, Martim Francisco, José Bonifácio, Vergueiro, Varnhagen e Calógeras, entre outros que escreveram sobre esse estabelecimento por diversas razões, em especial, para sustentar-se o pioneirismo de Ipanema em face de outras fábricas existentes em Minas Gerais, destacando, ademais, a intriga entre o primeiro diretor, o sueco Carl Gustav Hedberg e seu sucessor, Frederico Luis Guilherme Varnhagen. No século XX, esses relatos buscavam analisar os malogros da siderurgia nacional até a década de 1970, na intenção de obterem-se lições do passado. / This dissertation examines the construction of history and memory of the Fabrica de Ferro de São João de Ipanema, in Sorocaba, from the RG Collingwoods approach, who created the wellknown concept of scissors-and-paste\" history, in order to criticize historical writings or historiographical practices in which their authors work uncritically with produced reports, getting them from available sources to the researcher and selected from formal logic operations: similar information remain in the text and conflicting information are selected, discarding the supposedly wrong or inaccurate ones. A distintion among memory, collective memory, history and forgetting was made, present mainly in the work of Maurice Halbwachs Paul Ricoeur, and the concepts of progress and history magistra vitae, which appear mainly in the reports produced in the 20th Century. This plant, which was one of the first industrial activities in Brazil, whose origin was in the 16th Century, was object of interest of several people, like Peter Taques, Martim Francisco, Jose Bonifacio, Vergueiro, Varnhagen and Calógeras, among others who wrote about Ipanema for various reasons, in particular, to stress the pioneering of Ipanema in the face of other plants in Minas Gerais, noting, moreover, the conspiracy between the first Ipanemas Director, the Swedish Carl Gustav Hedberg and his successor, the German Frederico Luis Guilherme Varnhagen. In the 20th Century, these reports sought to examine the failures of the national steel industry until the 1970s, in order to get to lessons of the past.

The trypsin inhibitor, named ITC, had Mr of 32.5 kDa by SDS-PAGE and was composed by two subunits with 27.7 and 5.6 kDa linked by disulphide bridges, a typical characteristic of Kunitz-Inhibitor family. ITC was stable until 50?C, and at 100?C its residual activity was of about 60%. Also, ITC was stable at pHs 2 to 12. The inhibition of trypsin by ITC was non-competitive, with a Ki of 8,8 x 10-7M. ITC inhibits weakly other serine proteinases such as chymotrypsin and elastase. The inhibition of papain (44% of inhibition), a cysteine proteinase was an indicative of the bi-functionality of ITC. In vitro assays against digestive proteinases from several Lepdoptera, Diptera and Coleoptera pests were made. ITC inhibited in 100% digestive enzymes of Ceratitis capitata (fruit fly), Spodoptera frugiperda and Alabama argillacea, the last one being a cotton pest. It also inhibited in 74.4% Callosobruchus maculatus (bean weevil) digestive enzymes, a Coleoptera pest. ITC, when added in artificial diet models, affected weakly the development of C. capitata larvae and it had a WD50 of 2.65% to C. maculatus larvae / Um inibidor de proteinase foi isolado de sementes de Crotalaria pallida por fracionamento com sulfato de am?nio, cromatografia de afinidade em Sepharose com tripsina acoplada e precipita??o com ?cido tricloroac?tico (TCA). O inibidor de tripsina, denominado ITC, possui massa molecular de 32,5 kDa determinada por SDS-PAGE e ? composto por duas subunidades, uma de 25,7 e outra de 5,6 kDa, ligadas por pontes dissulfeto; uma caracter?stica t?pica da fam?lia de inibidores de Kunitz. ITC foi est?vel at? 50?C e a 100?C sua atividade residual foi cerca de 60%. ITC tamb?m foi est?vel em valores de pHs variando de 2 a 12. A inibi??o da tripsina por ITC ? do tipo n?o-competitivo, com um Ki de 8,8 x 10-7M. ITC inibe fracamente outras proteinases ser?nicas como quimotripsina e elastase. A inibi??o da papa?na (44%), uma proteinase ciste?nica, foi indicativa da bifuncionalidade de ITC. Ensaios in vitro contra proteinases digestivas de v?rios insetos praga das ordens Lepidoptera, Diptera e Coleoptera foram realizados. ITC inibiu em cerca de 100% enzimas digestivas de Ceratitis capitata (mosca-das-frutas), Spodoptera frugiperda (lagarta do cartucho do algod?o), e Alabama argillacea (curuquer? do algod?o). ITC tamb?m inibiu em 74,4% enzimas digestivas de Callosobruchus maculatus (broca do feij?o) uma praga da ordem Coleoptera. ITC, quando adicionado a dietas artificiais, afetou fracamente o desenvolvimento de larvas de C. capitata e teve um WD50 de 2,65% contra larvas de C. maculatus
