摘要

Effect of 4 constant temperatures ranging from 20 to 35℃ on development of immature oleander hawk moth, Daphnis nerii (L.) was studied. Development occurred at all temperatures, however, survival was lowest at 20 and 30℃. The proportion of time spent in each life stage from hatch to adult about 10.3% for 1st instars, 6.8% for 2nd instars, 7.6% for 3rd instars, 9.5% for 4th instars, 13.4% for 5th instars, 7.8% for pre-pupal stage, and 44.6% for pupal stage. A developmental threshold of 1.35℃ was estimated for development from hatch to adult emergence. Development from hatch to adult emergence was fastest at 30℃, taking about 23 days, and slowest at 20℃ taking about 60 days.

本報告在實驗室中研究4種定溫對夾竹桃天蛾幼蟲發育之影響。天蛾幼蟲在所測試的定溫下均能發育，唯在20℃及35℃時存活率最低。幼蟲孵化至成蟲羽化所耗費時間的百分比如下：第一齡幼蟲佔10.3﹪、第二齡幼蟲佔6.8﹪、第三齡幼蟲佔44.6﹪、第四齡幼蟲佔9.5﹪、第五齡幼蟲佔13.4﹪、前蛹期佔7.8﹪、蛹期佔44.6﹪。幼蟲孵化至成蟲羽化的發育在30℃時最快，約需23天，在20℃時最慢，約需60天。發育的臨界溫度是1.35℃。
