Abstract The objective of the current study was to carry out a survey of the main anatomopathological alterations in raising quails and evaluate possible interference of these in the bone tissue. To obtain the data, 23 quails were collected from farm in the central Serrana region of Espírito Santo. Necropsies with macroscopic descriptions, microbiological, coproparasitological, radiographic and histomorphometric tests were carried out. It was done data descriptive analysis and average comparision using Student T test. It was found that they presented lesions predominantly in the digestive system, followed by urinary and reproductive, and muscular system, were the altered color of the liver (47%) was the most frequent lesion. In the parasitological exams, it was found oocysts of Eimeira sp. (39.13%). In the microbiological exams, it was detected predominantly Escherichia coli (83%). Moderate osteopenia in quails, but the percentage of trabecular bone on bones was similar between healthy and diseased quails, without bone changes in histology. Microscopically, it was observed lung congestion as predominant lesion. It is concluded that there was predominance of alterations in the digestive system and mild parasitic infection; and although there was moderate level of osteopenia, there wasn’t bone change as a result of the observed infections. tissue 2 Santo descriptions coproparasitological test reproductive 47% 47 (47% lesion exams sp 39.13%. 3913 39.13% . 39 13 (39.13%) 83%. 83 83% (83%) histology Microscopically infection wasnt wasn t infections 4 (47 391 39.13 3 1 (39.13% 8 (83% (4 39.1 (39.13 (83 ( 39.

Este trabalho objetivou avaliar o potencial biótico e parâmetros da tabela de vida e fertilidade de Spodoptera albula (Walker, 1857) em condições controladas (25 ± 1°C, 70 ± 10% UR e fotofase de 14 horas). Avaliou-se a longevidade, períodos de pré, pós e oviposição, fecundidade e fertilidade de 13 casais. A longevidade das fêmeas (13,500 dias) foi significativamente maior que a dos machos (11,154 dias). A duração dos períodos médios de pré, pós e oviposição foram de 2,615, 1,769 e 9,385 dias, respectivamente. A fecundidade média foi de 1.417,69 ovos e a fertilidade 1.340,401 larvas por fêmea. Em média, as fêmeas copularam 1,231 vezes. Observou-se forte correlação positiva entre número de cópulas e a fecundidade (r = 0,847, p < 0,001) e, forte correlação negativa, entre o número de cópulas e a duração do período de pré-oviposição (r = -0,762, p = 0,002), e a longevidade (r = -0,788, p = 0,001). O potencial biótico de S. albula foi estimado em 8,768 x 1022 indivíduos/fêmea/ano. A taxa líquida de reprodução (Ro) foi de 353.904 vezes por geração e o tempo médio de uma geração (T) foi de 37,187 dias. A taxa intrínseca de aumento (rm) foi de 1,105, com uma razão finita de aumento (λ) de 3,019.

This study aimed to evaluate the biotic potential, life table parameters and fertility of Spodoptera albula (Walker, 1857) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photo phase). The longevity, pre, post and oviposition periods, fecundity and fertility of 13 couples were evaluated. The longevity of females (13.500 days) was significantly higher than those of males (11.154 days). The mean durations of the pre, post and oviposition periods were 2.615, 1.769 and 9.385 days, respectively. The mean fecundity was 1.417.69 eggs and mean fertility was 1.340.401 larvae, per female. On average, females copulated 1, 231 times. A strong positive correlation was observed between the number of copulations and fecundity (r = 0.847, p <0.001), as well as a strong negative correlation between the number of copulations and the duration of the pre-oviposition period (r = -0.762, p = 0.002), and longevity (r = -0.788, p = 0.001). The biotic potential of S. albula was estimated at 8.768 x 1022 individuals / female / year. The net reproductive rate (Ro) was 353,904 times per generation and the mean generation time (T) was 37.187 days. The intrinsic rate of increase (rm) was 1,105, with a finite rate of increase (λ) of 3,019.

Este estudo objetivou detalhar parâmetros biológicos dos estágios imaturos de Spodoptera albula (Walker 1857) em condições controladas (25 ± 1°C, 70 ± 10% UR e fotofase de 14 horas) e reunir informações sobre as plantas hospedeiras de suas larvas. Para tanto foram empregadas e validadas novas metodologias de criação e dieta artificial. A viabilidade das fases de ovo, larva, pré-pupa e pupa foi de 94,54; 97,33; 93,84 e 92,34%, respectivamente. A duração média das fases de ovo, larva, pré-pupa e pupa foi de 4,14; 16,37; 1,69; e 9,34 dias, respectivamente. Na fase de larva observou-se que 80,85% das fêmeas e 93,99% dos machos passaram por seis instares e os demais por sete, com protandria larval significativa. As larvas que passaram por seis e sete instares apresentaram razão média de crescimento de 1,58 e 1,48, respectivamente. Foram relacionadas 55 plantas pertencentes a 29 famílias botânicas. As pupas femininas foram significativamente maiores, observando-se protoginia. Tanto a metodologia de criação quanto a dieta larval mostraram-se adequadas, pois permitiram sobrevivência total de praticamente 80% e um detalhamento muito maior das observações relacionadas ao ciclo biológico, especialmente do estágio larval.

This study aimed to detail the temporal and morphological parameters of the immature stages of Spodoptera albula (Walker 1857) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase) and to gather information about their larval host plants. For this purpose, a new rearing method and artificial diet was employed and validated. The viability of the egg, larval, pupal and pre-pupal stages was 94.54, 97.33, 93.84 and 92.34%, respectively. The average duration of the egg, larval, pupal and pre-pupal stages was 4.14, 16.37, 1.69, and 9.34 days, respectively. During the larval stage, 80.85% of females and 93.99% of males passed through six and remaining through seven instars, with significant larval protandry. The larvae that developed through six and seven instars exhibited a mean growth rate of 1.58 and 1.48, respectively. Fifty five host plant species belonging to 29 families are listed. The female pupae were significantly larger, exhibiting protogyny. Both the rearing methods as well as the larval diet proved adequate, providing more detailled observations of the biological cycle, especially the larval stage, and resulting in an overall survival of almost 80%.
