RESUMO
Experiments with Squamatoides trivittatus were carried out in two different controlled temperatures (16ñ1§C/50-60 per cent RH and 27ñ1§C/70-80 per cent RH). The viability of larvae and pupae at 27§C was 89.82 per cent and 92.75 per cent respectively. Larvae did not develop at 16§C. Larval development lasted for 20ñ4hr, 16ñ8 hr and 60ñ7 hr for the first, second and third instars, respectively, completing a total of 96ñ6 hr. The mean pupal period lasted for 15.7ñ1.6 days. In longevity tables for the adults, life-expectancy for 50 per cent of the colony submitted to 16§C was of 1.78 weeks for males and 2,42 for females. At 27§C a life-expectancy of 1.15 weeks for males and 0.78 week for females was recorded. The average life-spans for males and females at 16§C were 3.5ñ2.0 and 3.8ñ2.6 weeks, respectively, and 1.9ñ1.2 weeks for both sexes. At 27ñC, the longevity recorded was of 2.1ñ1.3 weeks for males and 1.7ñ1.1 week for females.
