We monitored a population of Carolina Hemlocks in northwestern North Carolina for four years to examine the rate and pattern of decline in response to infestation by Adelges tsugae (Hemlock Woolly Adelgid). Our yearly census of hemlock condition and severity of the adelgid infestation included trees of all sizes. We estimated declines in condition as the portions of the leaf canopy that were lost. Initially, infestation occurred throughout the population but was severe in only a small cluster of individuals. Within 1 year, the area of severe infestation increased in size to encompass 48% of the population. In another region of the population, there was a cluster of relatively healthy individuals comprised largely of seedlings. Of the 4 size-classes of trees, sapling-sized individuals experienced the highest rates of decline in condition. Most trees declined to poor health within 3 years of an observation of moderate to severe infestation.

The thesis studied the biological control of woolly aphid (Eriosoma lanigerum Hausm.) using European earwig (Forficula auricularia L.) in an Australian apple orchard IPM program. Woolly aphid populations were monitored over the 1995/96 and 1996/97 growing seasons, completing a four year study of the pest's status and management under IPM programs at Bathurst in the Central Tablelands of NSW. Woolly aphid infestation in 2 IPM treatments, based on alternative control techniques for codling moth (Cydia pomonella L.), namely mating disruption and fenoxycarb, were compared with a conventional insecticide azinphos-methyl program. Further, the thesis studied the toxicity, to adult European earwigs, of chemicals commonly used in Australian apple orchards. The pesticide alpha-cypermethrin is highly toxic to weevil spp. and is used by apple growers in Western Australia for their control, but it is also toxic to earwigs. This trial investigated the potential of alpha-cypermethrin to disrupt the biological control of woolly aphid. Following a single application as a butt spray, alpha-cypermethrin suppressed the number of earwigs in apple trees for 14 weeks. The single application did not reduce earwig numbers to the extent that the biological control of woolly aphid was lost, however a full season program with applications every 14 to 21 days to all trees, as recommended to control weevils, within an orchard is likely to be very disruptive. The research also studied the control of woolly aphid using insecticide root-soil drenches. Imidacloprid provided excellent control of woolly aphid for 3 seasons. Pirimcarb provided some suppression of woolly aphid during the first season, but not in subsequent seasons. Chlorpyrifos and vamidothion failed to control woolly aphid in any season. / Doctor of Philosophy (PhD)

Studies of secondary seed dispersal by small mammals have largely been focused on the interaction between nut-bearing tree species and sciurid rodents such as squirrels, and on heteromyid rodents in the southwestern United States. However, there is now evidence that wind-dispersed tree species such as pines also undergo a process of secondary seed dispersal, where animals redistribute (cache) seeds that have already fallen to the ground, often in microhabitats more suitable for successful seed germination. In Florida sandhill, where fire suppression has threatened wind-dispersed longleaf pine ( Pinus palustris) by encouraging the encroachment of hardwoods such as sand live oak ( Quercus geminata), secondary seed dispersal may be an important factor in determining community composition and persistence of longleaf pine systems. Using a combination of seed depots and seed predator exclosures, I looked at both longleaf pine and sand live oak in terms of whether small animals such as squirrels ( Sciurus carolinensis) and cotton mice ( Peromyscus gossypinus) cache the seeds, and where the seeds of these two tree species best germinate. Since sand live oak acorns are prone to infestation by weevils ( Curculio spp.), I also examined whether nut condition affects acorn germination potential. I found that longleaf pine seeds are cached by small mammals to a small degree. While these seeds are not moved great distances from where they originate, they are often redistributed into microhabitats that promote successful seed germination. Caging experiments indicated that seeds were most likely to germinate when buried in open areas between adult trees, and to some degree, under shrub cover. On the other hand, sand live oak acorns appear to face heavy predation by large seed predators such as raccoons ( Procyon lotor) and wild pigs (Sus scrofa). Those acorns that do escape predation, including weevil-infested acorns, may provide an opportunity for seedling establishment. However, it appears that sand live oak depends heavily on vegetative sprouting for regeneration. This suggests that even in the absence of fire, longleaf pines in Florida sandhill are able to persist through secondary seed dispersal by small animals coupled with heavy seed predation on competing sand live oak.

Lithuania’s agricultural reform resulted in significant changes in land use, i.e. in the emergence of small individual farms. As a result, the formerly most popular 7, 8, 9-course crop rotations, or even 5-6-course crop rotations became inapplicable on small farms, especially on those not involved in animal production and cultivation of grass forage. Multiple-course crop rotations would disperse the same crops over several places, and the fields would not be unacceptably small. This is especially problematic for market farms, where it is intended to have 1-2-3 main crops and adequately alternate them. In foreign countries short rotations are a common practice in similar cases. However, in Lithuania short rotations have hardly been investigated, except for the sporadic research cases, therefore it is rather complicated to judge the feasibility of market crops growing in short rotations. When the area of cereals is increased in a crop rotation, it is more difficult to choose preceding crops, and continuous growing of crops becomes inevitable. It is of special relevance here to maintain soil fertility, moreover, the adverse effects of crops concentration manifest themselves much more severely than in any other system, namely, heavy occurrence of weeds, diseases and pests, soil depletion and fatigue. On cultivated Central Lithuania’s soils shortening of rotations and proper choice of preceding crops make it feasible to produce profitable, high quality agricultural production... [to full text]

No artificial (Exp. I), os animais foram distribuídos em 9 grupos, com três repetições/tratamento. Cada animal foi infestado com 50 larvas em quatro incisões cutâneas, totalizando 200/animal. As larvas L1 foram infestadas com um intervalo de três a seis horas, de 24 e de 48 horas. Os grupos receberam os seguintes tratamentos: spinosad (50 e 150 ppm) e um controle sem tratamento. Os animais foram examinados com: 15, 30, 60 minutos e 6, 24 e 48 horas. Larvas que abandonavam as lesões foram colhidas e colocadas para pupar em BOD a 25°C e 90% de UR. Os resultados demonstraram que spinosad (50 e 125 ppm) atingiu 100% de eficácia no tratamento contra os três estádios larvários de C. hominivorax. A concentração de 125 ppm alcançou este valor mais rapidamente. Nos estudos com infestações naturais (Exp. II e III), os animais após receberem incisões cutâneas foram liberados a pasto para que ocorressem infestações. Detectada a presença de larvas, o animal era alocado, por sorteio, para um dos grupos experimentais. No experimento II utilizou-se spinosad 50 e 150 ppm e no experimento III 250 e 400 ppm. Como tratamentos positivos, foram utilizados: chlorpyriphos e uma associação de chlorphenvinphos + dichlorvos. Os animais foram examinados diariamente do dia zero (D0) até dia 12 (D12). Ficou demonstrado nos experimentos com infestação natural que spinosad 50 e 150 ppm apresentaram eficácia inferior a 100%, enquanto que a 250 e 400 ppm proporcionaram 100% de eficácia decorridas 24 horas do tratamento, a concentração com 400 ppm alcançou este valor decorridos 12 horas pós tratamento. / Three experiments were conducted, the first one with an artificial infestation and the other two with natural infestation. In the first experiment (artificially infested) the animals were divided into 9 experimental groups, three repetition per treatment. Each animal was inoculated with 200 larvae in four skin incisions, two on the palette and two in the rump, each one containing 50 larvae. The placement of L1 larvae followed a range of 3 to 6 hours, 24 hours and 48 hours. The experimental groups had the following repetitions: spinosad 50 and 125 ppm, and a control group (untreated). After the treatment the animals were examined on the following period: 15, 30, 60 minutes, 6, 24 and 48 hours. Larvae which left the incision were taken for pupation on 25°C and 90% relativity humidity. The results demonstrated spinosad 50 and 125 ppm reached 100% effectiveness on the treatment of artificially caused myiasis by the three larval stages (L1, L2 and L3) of Cochliomyia hominivorax, in which the spinosad 125 ppm achieved it quicker. In the other experiments with natural infestation, after the skin incisions the animals were release on the field for the concurrency of the natural infestation. Once detected the presence of the larvae, the animals were randomly allocated in one of the experimental groups. On the experiment I were used the following concentration: spinosad 50 and 150 ppm on the experiment II spinosad 250 and 400 ppm. On both experiments were used two positives treatments: chlorpyriphos and a association of chlorphenvinphos plus dichlorvos. The animals were daily examined, from day zero (D0) to day 12 (D12).The results of the two experiments with natural infestation indicate that spinosad 50 and 150 ppm were not effective, showing effectiveness lower than 100%. However, spinosad 250 and 400 ppm reached 100% of efficacy were after 24 hours... (Complete abstract click electronic access below)

A incidência de moscas-das-frutas é um fator de preocupação todos os anos nos perímetros irrigados do norte de Minas Gerais, principalmente em pomares de goiaba, acarretando aumentos nos custos e perdas na produção. Para se estabelecer um programa de controle de moscas-das-frutas, torna-se necessário o prévio conhecimento dos aspectos ecológicos dos tefritídeos e seus parasitóides. Portanto, o presente trabalho teve por objetivo conhecer a biodiversidade de moscas-das-frutas e de seus parasitóides em dois pomares comerciais de goiaba da região, os índices de infestação das moscas-das-frutas e a capacidade de Diachasmimorpha longicaudata parasitar moscas-das-frutas em goiaba no norte de Minas Gerais. Após três anos de coletas, em armadilhas tipo McPhail e em frutos, foram coletados 48.482 tefritídeos, sendo 45.012 exemplares de Anastrepha e 3.470 de Ceratitis capitata. Foram capturadas 18 espécies de Anastrepha, sendo que, A. turpiniae, A. manihoti, A. leptozona e A. barbiellinii estão sendo registradas pela primeira vez no norte de Minas Gerais. A. zenildae e A. fraterculus representaram mais de 90% de todas as moscas coletadas em armadilhas, sendo associadas às classes “super” de dominância, freqüência, abundância e constância. Somente C. capitata, A. zenildae, A. fraterculus, A. sororcula, A. obliqua e A. turpiniae emergiram das amostras de frutos. Destas, A. zenildae (58,8%), A. fraterculus (13,5%) e C. capitata (20,7%) corresponderam a 93% do total de fêmeas coletadas, sendo as responsáveis pelos altos níveis de infestação do pomar de Jaíba. Em Nova Porteirinha, somente três espécies de Anastrepha foram relacionadas aos frutos: A. fraterculus (50,3%), A. zenildae (37,8%) e A. obliqua (3,2%), além de C. capitata (8,6% do total de fêmeas). Nos dois pomares, as maiores infestações ocorreram de março a julho/2003, influenciadas principalmente pela disponibilidade de frutos maduros. Ocorreu interação de A. zenildae e A. fraterculus na exploração da goiaba no pomar de Nova Porteirinha. Foi discutida a relação entre percentagem de infestação e intensidade de infestação. O parasitismo natural de moscas-das-frutas em goiabas nos pomares comerciais do norte de Minas Gerais foi muito baixo. Dos 283 parasitóides obtidos, somente o braconídeo Doryctobracon areolatus e três espécimes do eucoilíneo Aganaspis pelleranoi foram registrados. Houve correlação positiva entre o número de adultos de opiíneos e os de Anastrepha spp. Foram recuperados 37 espécimes de D. longicaudata (24 em Jaíba e 13 em Nova Porteirinha), demonstrando que a espécie fechou o ciclo nas condições locais. Assim, D. longicaudata possui chances de se estabelecer na região, sem comprometer as relações tritróficas pré-existentes. / The occurrence of fruit flies is a factor of concern every year in the irrigated areas in the north of Minas Gerais State, mainly in guava orchards, because they cause increases in the costs and losses in the production. To establish a fruit fly program control, it is necessary the previous knowledge of the ecological aspects of the tephritids and its parasitoids. Therefore, the objective of this work was to know the biodiversity of fruit flies and its parasitoids in two commercial guava orchards, the fruit flies infestation levels and the capacity of Diachasmimorpha longicaudata to parasitize fruit flies in guava in the north of Minas Gerais State. After three years of samplings, with McPhail type traps and on fruits, a total of 48,482 tephritids, was collected being 45,012 specimens of Anastrepha and 3,470 of Ceratitis capitata. Eighteen species of Anastrepha were captured; A. turpiniae, A. manihoti, A. leptozona and A. barbiellinii were registered for the first time in the north of Minas Gerais State. A. zenildae and A. fraterculus represented 90% of all fruit flies collected in traps and were placed in the category “super” of dominancy, frequency, abundance and constancy. Only C. capitata, A. zenildae, A. fraterculus, A. sororcula, A. obliqua and A. turpiniae emerged from fruits. From these, A. zenildae (58,8%), A. fraterculus (13,5%) and C. capitata (20,7%) corresponded to 93% of the total females collected, and they caused high infestation levels in the orchard located in Jaiba. In Nova Porteirinha, three species of Anastrepha were associated to A. fraterculus (50,3%), A. zenildae (37,8%) and A. obliqua (3,2%), besides C. capitata (8.6% of the total females). In the two orchards, the highest infestation occurred from March to July/2003, influenced mainly by the availability of mature fruits. Interaction of A. zenildae and A. fraterculus occurred in the exploration of guava in the orchard located in Nova Porteirinha. The relationship between infestation percentage and infestation intensity was discussed. The natural parasitism of fruit flies in commercial guava orchards in the north of Minas Gerais State was very low. Of the 283 parasitoids collected, the braconid Doryctobracon areolatus and three specimens of the eucoiline Aganaspis pelleranoi were recorded. There was a positive correlation between the number of adults of braconids and the number of Anastrepha spp. It was recovered 37 specimens of D. longicaudata (24 in Jaiba and 13 in Nova Porteirinha), which revealed that this species completed the cycle under local conditions. Therefore, there is a great success in establishment of D. longicaudata in this region without damaging the preexisting tritrophic relations.

Four-hundred and thirty two felines, with no distinction for breed or sex and with different ages, were examined for the presence of external parsites, being 265 domesticated felines from Veterinary Clinics ambulatory routine, Commercial Raising Establishments and domestic collection, in the time period from August 2005 to July 2006; and 167 non-domesticated felines from the Zoonosis Control Center of João Pessoa city (CCZ/JP), that were collected in the time period from October 2005 to July 2006. For the analysis the SAS (StatisticalAnalysis System) software was used, inferential and descriptive statistical techniques were applied, to the significance level of 5% statistics. Considering the total sample, 271 animals were positive for external parasites infestation, being 62.7% the frequency in the studied sample, thus constituting the present study the first contribution to the knowledge of domesticated felines external parasites in the city of João Pessoa – PB. Six species of external parasites were identified on the domesticated and non-domesticated felines, with detected infestation by one or more parasites. The most frequent external parasite species was Ctenocephalides felis (27.3%), followed by Lynxacarus radovskyi (26.2%), Otodectes cynotis (17.4%), Felicola subrostratus (9.7%), Notoedres cati (2.1%) and Rhipicephalussanguineus (1.6%). An association between the infestation by external parasites and domestication, or non-domestication, of the animals was observed, with the existence of a significantly inferior percentage for domesticated animals in comparison to the one obtained for the non-domesticated. The only species of flea found was Ctenocephades felis. No significative difference between the presence offleas and the sex, age, breed, fur color, and fur size parameters was found. The most expressive clinical signs of infestation by fleas were not shiny fur 33.1% (39/118), alopecia 23.7% (28/118), stiff fur 16.9% (20/118) and itching 13.6% (16/118). By evaluating the nutritional condition, greater flea infestation positiveness was observed in animals that were underfed, that condition was statistically significant when the nutritional condition between the studied groups was compared. The obtained results allow us to conclude that the ectoparasitosis constitute important nosological entities in domesticated felines of João Pessoa city, in the state of Paraiba, caused mainly by Ctenocephalides felis and Lynxacarus radovskyi, being the domestication and the nutritional state of the animals the most influent epidemiological factors. / Objetivou-se com este estudo analisar a situação clínico-epidemiológica da infestação por ectoparasitos em felinos domésticos procedentes da cidade de João Pessoa – PB. Foram examinados para presença de ectoparasitos 432 felinos sem distinção de raça, sexo e com idades variadas, sendo 265 felinos domiciliados provenientes da rotina ambulatorial de Clínicas Veterinárias, Criadouros Comerciais e coleta em domicílio, no período de agosto de 2005 a Julho de 2006 e 167 felinos não domiciliados pertencentes ao Centro de Controle de Zoonoses do município de João Pessoa – PB (CCZ/JP), cujas coletas ocorreram a partir de outubro de 2005 a Julho de 2006. Para a análise foi utilizado o “software” SAS (Statistical Analysis System), aplicando-se técnicas de estatística descritiva e inferencial, ao nível de significância de 5% estatística. Considerando-se a amostratotal foram positivos para infestação por ectoparasitos 271 animais, sendo a freqüência de 62,7% na amostra estudada, constituindo-se o presente estudo na primeira contribuição para o conhecimento da ectoparasitofauna de felinos domésticos na cidade de João Pessoa – PB. Foram identificadas seis espécies de ectoparasitos nos felinos domiciliados e não domiciliados, detectando-se infestação por um ou mais parasitos. A espécie de ectoparasito mais freqüente foi Ctenocephalides felis (27,3%), seguido por Lynxacarus radovskyi (26,2%), Otodectes cynotis (17,4%), Felicola subrostratus (9,7%), Notoedres cati (2,1%) e Rhipicephalus sanguineus (1,6%). Observou-se associação entre a infestação por ectoparasitos e a domiciliação ou não dos animais, obtendo-se, para os animaisdomiciliados percentual significativamente inferior ao obtido para os não domiciliados. A única espécie de pulga encontrada foi Ctenocephades felis. Não foi constatada diferença significativa entre presença de pulgas e os parâmetros sexo,idade, raça, cor da pelagem, tamanho da pelagem e cor da pelagem. Os sinais clínicos mais expressivos em infestações por pulgas foram pêlo sem brilho 33,1% (39/118), alopecia 23,7% (28/118), pêlo eriçado 16,9% (20/118) e prurido 13,6% (16/118). Avaliando-se a condição nutricional foi observada maior positividade de infestação por pulgas em animais que apresentavam a condição subalimentado, sendo estatisticamente significativa quando se comparou a condição nutricional entre os grupos estudados. Os resultados obtidos permitem concluir que as ectoparasitoses constituem-se em importantes entidades nosológicas em felinos domésticos da cidade de João Pessoa - PB causadas principalmente porCtenocephalides felis e Lynxacarus radovskyi tendo como fatores epidemiológicos de maior influência a domiciliação e o estado nutricional dos animais.
