No. of bitstreams: 1 2012 - Adriana Cristina Pedroso Ferraz.pdf: 2396072 bytes, checksum: 4c8224201e7dfca3888239f1edd74e0f (MD5) Previous issue date: 2012-05-02 / CNPq / The research was divided into chapters. The first assessed the post-embryonic development of Chrysomya albiceps (Widemann) on chicken gizzard (control: beef). There were four replications (100g each diet, 40 1st instar/2nd generation larvae) per treatment, each recipient was placed in a larger one containing sawdust and then sealed. The mature larvae were weighed and stored in test tubes. The variation among mature larva weight means and the duration of the larva, pupa and total stages were analyzed by the Student t test (?=5%), the viabilities by ANOVA and the sex ratio by the chi-square test. The following were recorded: mean temperature 25.6oC and 72.4% relative air humidity, larva-adult period mean duration of 8.1 days (meat) and 8.2 days (gizzard); 71% to 87% larva viability; 100% and 99% pupa viability 58% and 67% larva and adult viabilities, respectively. Chicken gizzard was shown to be satisfactory as diet for C. albiceps. The second chapter assessed the post embryonic development of Chysomya putoria (Widemann) in chicken gizzard and homogenized chicken gizzard in 65% agar (control: meat). Four replications (60 mL diet, 40 1st instar/5th generation larvae) were made per treatment. The homogenate was prepared in a mixer (gizzard, distilled water and agar). A mean temperature of 20.6 oC and 67.7% relative air humidity were recorded. The mean duration of the larva-adult period was 8.868 days (meat), 8.676 days (gizzard) and 9.067 days (homogenate); the larva viability was 98%; 92% and 73%; the pupa viability was 98%; 91% and 71%; the larva and adult viabilities were 93%; 83% and 64%, respectively. There were significant difference in the duration of the pupa period between meat and the homogenate. Both diets were shown to be satisfactory for C. putoria. The third chapter assessed different ciprofloxacin concentrations (3.33 ?g/mL; 6.66 ?g/mL and 13.33 ?g/mL in gizzard/65% agar homogenate) on C. putoria development (the control received distilled water). They were replicated four times (60 grams diet, 40 1st instar/3rd generation larvae) in an acclimatized chamber 30oC day/28 oC night, 70+10%relative air humidity and 14-hour photoperiod. There was no significant difference for: mean individual larva weight, mean duration of the larva inoculation until abandonment and the larva, pupa and total stages. Only treatment 2 differed significantly from the control in the larval and total viability. Ciprofloxacin seemed not to alter C. putoria development. The fourth chapter assessed different gentamicin concentrations (4.44?g/mL; 13.33?g/mL and 66.66?g/mL) on C. putoria. The materials and methods were similar to those of chapter III. There was no significant difference for: mean individual larva weight, mean duration of the larva inoculation until abandonment and the larva, pupa and total stages. Only treatment 2 differed significantly from the control for larva viability. Gentamicin seemed not to alter C. putoria development. The fifth chapter assessed different ampicillin concentrations (66?g/mL; 81.33?g/mL and 166.66?g/mL) on C. putoria. The materials and methods were similar to chapter III. There was no significant difference for: mean individual larva weight, mean duration of the larvae inoculation until abandonment and the larval, pupa and total stages. There was no significant difference for larva and total viability, but pupa viability in T1 differed significantly from the control and T2, and T3 differed from the control. Ampicillin seemed not to alter C. putoria development. / A pesquisa foi dividida em cap?tulos. O primeiro avaliou o desenvolvimento p?s-embrion?rio de Chrysomya albiceps (Widemann) em moela de frango (controle: carne bovina). Foram quatro repeti??es (100g de dieta cada, 40 larvas de 1? instar/2? gera??o) por tratamento, cada recipiente inserido em outro maior contendo serragem e vedado. As larvas maduras foram pesadas e armazenadas em tubos de ensaio. A varia??o entre m?dias de massa de larvas maduras e dura??es dos est?gios de larva, pupa e total foram analisadas por Teste t de Student (?=5%), as viabilidades por ANOVA, a raz?o sexual pelo qui-quadrado. Foram registradas temperatura m?dia 25,6?C e umidade relativa do ar m?dia 72,4%; dura??o m?dia do per?odo de larva a adulto 8,1 dias (carne) e 8,2 (moela); viabilidades de larva 71% e 87%; viabilidades de pupa 100% e 99%; viabilidades de larva a adulto 58% e 67%, respectivamente. Moela de frango se mostrou satisfat?ria como dieta para C. albiceps. O segundo cap?tulo avaliou desenvolvimento p?s-embrion?rio de Chysomya putoria (Widemann) em moela e homogenato de moela de frango em agar 65% (controle: carne). Foram quatro repeti??es (60 mL de dieta, 40 larvas de 1? instar/5?gera??o) por tratamento. O homogenato foi preparado em mixer (moela, ?gua destilada e agar). Foram registradas temperatura m?dia 20,6? C e umidade relativa do ar m?dia 67,7%. A dura??o m?dia do per?odo de larva a adulto foi 8,868 dias (carne), 8,676 (moela) e 9,067 (homogenato); as viabilidades larvais 98%; 92% e 73%; as viabilidades de pupa 98%; 91% e 71%; as viabilidades de larva a adulto 93%; 83% e 64%, respectivamente. Houve diferen?a significativa na dura??o do per?odo pupal entre carne e homogenato. Ambas dietas mostraram-se satisfat?rias para C. putoria. O terceiro cap?tulo avaliou diferentes concentra??es de ciprofloxacino (3,33 ?g/mL; 6,66 ?g/mL e 13,33 ?g/mL em homogenato de moela/agar 65%) sobre desenvolvimento de C. putoria (controle recebeu agua destilada). Foram replicados quatro vezes (60 gramas dieta, 40 larvas 1? ?nstar/3? gera??o) em c?mara climatizada 30?C dia/28?C noite, 70+10% U.R. e 14 horas fotoper?odo. N?o houve diferen?a significativa: massa individual m?dio das larvas, dura??o m?dia da inocula??o das larvas at? abandono e est?gios larval, pupal e total. Apenas tratamento 2 diferiu significativamente do controle nas viabilidades larval e total. Ciprofloxacino pareceu n?o alterar desenvolvimento de C. putoria. O quarto cap?tulo avaliou diferentes concentra??es de gentamicina (4,44?g/mL; 13,33?g/mL e 66,66?g/mL) sobre C. putoria. Os materiais e m?todos foram semelhantes ao do cap?tulo III. N?o houve diferen?a significativa: massa individual m?dia das larvas; dura??o m?dia da inocula??o das larvas at? abandono e dos est?gios larval, pupal e total. Apenas tratamento 2 diferiu significativamente do controle na viabilidade larval. Gentamicina pareceu n?o alterar o desenvolvimento de C. putoria. O quinto cap?tulo avaliou diferentes concentra??es de ampicilina (66?g/mL; 81,33?g/mL e 166,66?g/mL) sobre C. putoria. Os materiais e m?todos foram semelhantes ao cap?tulo III. N?o houve diferen?a significativa: massa individual m?dia das larvas, dura??o m?dia da inocula??o das larvas at? abandono e est?gios larval, pupal e total. N?o houve diferen?a significativa: viabilidades larval e total, por?m viabilidade pupal do T1 diferiu significativamente do controle e T2, e T3 diferiu do controle. Ampicilina pareceu n?o alterar desenvolvimento de C. putoria.
