Exigências Térmicas, Período de Desenvolvimento e Sobrevivência de Imaturos de Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae)

The development and survival of the immature stages of the lesser mealworm Alphitobius diaperinus (Panzer) were studied at four constant temperatures (22°C, 25°C, 28°C, and 31°C). The development was completed at all temperatures. At 22°C, longer development period and lower survival were observed....

Summary:The development and survival of the immature stages of the lesser mealworm Alphitobius diaperinus (Panzer) were studied at four constant temperatures (22°C, 25°C, 28°C, and 31°C). The development was completed at all temperatures. At 22°C, longer development period and lower survival were observed. The optimal temperature was 31°C which promoted shorter development and higher survival. The basal temperature and thermal constant for egg, larva and pupa development were: 17.8°C, 19.2°C, and 16.5°C and 40.09, 239.48 and 59.56 degree-days, respectively. Estudou-se, em laboratório, o efeito de quatro temperaturas constantes (22ºC, 25ºC, 28ºC e 31ºC) sobre as fases imaturas de Alphitobius diaperinus (Panzer). Houve desenvolvimento de imaturos nas quatro temperaturas estudadas, sendo que a 22ºC observou-se maior duração do desenvolvimento e menor sobrevivência. A temperatura de 31°C foi a mais favorável para o desenvolvimento dos imaturos, com alta sobrevivência. Os estágios de ovo, larva e pupa apresentaram temperatura base (Tb) de 17,8ºC, 19,2ºC e 16,5ºC, respectivamente. As constantes térmicas (K) foram de 40,09 graus-dia (GD) para ovo, 239,48 GD para larva e 59,56 GD para pupa.
