Objetivou-se estudar a biologia de Automeris illustris (Walker, 1855), um hemileucíneo polifitófago considerado praga secundária da eucaliptocultura e cujas lagartas podem provocar erucismo. Os parâmetros biológicos foram obtidos em condições controladas de temperatura: 25 ± 1ºC, UR 70 ± 10% e fotofase de 14 horas, com observações diárias. Foram avaliados, em cada fase de desenvolvimento, aspectos morfológicos e etológicos, duração e viabilidade. Para relacionar as plantas hospedeiras foram reunidos dados de material coletado em campo e já referidos em bibliografia. Nas condições de laboratório observou-se que o ciclo de vida necessitou de aproximadamente 121 dias, cujos períodos médios das fases de ovo, lagarta, pré-pupa, pupa e adulta foram de 10,60; 80,56; 3,58; 19,17 e 7,83 dias, respectivamente. As lagartas passaram por seis ínstares e tiveram uma razão média de crescimento de 1,47. Observou-se um alto grau de polifitofagia sendo relacionadas 51 plantas hospedeiras pertencentes a 28 famílias. O potencial biótico foi estimado em 8.719.556 indivíduos ao ano.
ABSTRACT. Culicinae (Diptera, Culicidae) occurring in the State of Rio Grande do Sul, Brazil. This work lists the species of Culicinae recorded in the State of Rio Grande do Sul, Brazil. The present data is based on adult collections carried out in 11 physiographic zones from September/2001 to August/ 2002, published literature and entomological collection records. Fifty-seven species are listed, including 22 new occurrences to Rio Grande do Sul. The present study increased the geographic distribution range of Aedeomyia
In order to characterize the ecosystems of fruit trees of the West Region of Santa Catarina State in relation to the Tephritidae species from twelve different fruit species grown in orchards located in four counties (Chapecó, Cunha Porã, São Carlos and Xanxerê), McPhail traps, baited with glucose 10%, were used to sample flies, from October 1998 to September 2000. To characterize the faunistic fruit flies populations of each county, the abundance index, constancy, dominance and frequency of fruit flies population were analyzed. A total of 8,393 specimens of fruit flies were collected, belonging to 20 species in seven genera. In Chapecó, 17 fruit flies were sampled, corresponding to an index of diversity of 2.0, followed by Cunha Porã with ten species and an index of 1.5. In Xanxerê the index was 1.1 to eight species. The smallest index was found in São Carlos (0.9), to seven species. Ceratitis capitata (Wied.) was found accidental in almost all the orchards, with exception to one orange orchard in São Carlos, where it was accessory. Anastrepha fraterculus (Wied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
