【 摘 要 】

Experiments with Squamatoides trivitattus were carried out in two different controlled temperatures (16±1°C/50-60% RH and 27±1°C/70-80% RH). The viability of larvae and pupae at 27°C was 89.82% and 92.75% respectively. Larvae did not develop at 16°C. Larval development lasted for 20±4 hr, 16±8 hr and 60±7 hr for the first, second and third instars, respectively, completing a total of 96±6 hr. The mean pupal period lasted for 15.7±1.6 days. In longevity tables for the adults, life-expectancy for 50% 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 3.5±2.0 and 3.8±2.6 weeks, respectively, and 1.9±1.2 weeks for both sexes. At 27°C, the longevity recorded was of 2.1±1.3 weeks for males and 1.7±1.1 week for females.
