Resumo
The colony of C. albiceps (Wiedemann, 1819) was established from larvae and adults colected in the "Estação para Pesquisa Parasitológica W.O. Neitz" area at UFRRJ and Seropedica District, Itaguai, Rio de Janeiro. (Latitude: 22º45'S; Longitude: 43º41'W and Altitude: 33 metres). The biological aspects of this species were studied in climatized chambers regulated at 60±10% RH and 14 hours photophase. The duration and the viability of the larval and pupal stages of C. albiceps was 5,2 and 4,53 days; 95,75% and 94%, respectively. An effect of group was observed on the larvae at the first and second instar. The average weight of mature larvae was around 75 mg, varying between 12,2 to 120 mg. Only mature larvae with average weight higher than 42 mg have originated adults. Oviposition peaks between the sixth and tenth days pos-emergence were observed. Survival curves of the males and females were estimated using the Weibull model.
