麝凤蝶的发育起点温度和有效积温

在 1 6～ 3 1℃范围内设置了 6个温度对麝凤蝶ByasaalcinousKlug卵、幼虫、蛹的发育速率进行了测定。结果表明 ,卵、幼虫、蛹在 1 6～ 3 1℃范围内均能正常生长发育 ,尤以 2 5～ 2 8℃条件下最适宜于该蝶的生长发育 ,发育速率与温度呈直线关系。用直线回归法得到卵、幼虫、蛹的发育起点温度分别为 9 3 ,7 1 ,6 8℃ ,有效积温分别为 90 2 ,3 87 4,2 2 7 9日·度。

Threshold development temperature and effective temperature sum of Byasa alcinous

The developing rates of egg, larva and pupa for Byasa alcinous Klug were tested at the following six constant temperatures.The optimal temperatures of the growth and development were among 16,19,22,25,28 and 31℃.The results showed that egg,larva and pupa can normally develop between 16～31℃.The optimal temperatures of the growth and development were between 25～28℃.All the relationships between developing rate and temperature followed linear forms.The threshold development temperatures for egg,larva and pupa were 9^3,7^1 and 6^8℃,and the effective temperature sums for these stages were 90^2,387^4 and 227^9 degree-day.
