摘要：

设置16、19、22、25、28和31 ℃ 6个温度梯度条件,研究了温度对浙江天童国家森林公园9种鳞翅目昆虫繁殖力的影响.结果表明： 9种鳞翅目昆虫在19～28 ℃范围内可顺利产卵并孵化,随温度升高成虫的产卵前期缩短;四川尾尺蛾等8种昆虫在22 ℃时繁殖力最强,之美苔蛾最大繁殖力出现在25 ℃;9种昆虫的卵期随温度升高而缩短;产卵同步性和卵孵化同步性最大值均出现在较高的温度条件下.四川尾尺蛾卵的发育起点温度较低,为9.52 ℃,其他8种昆虫卵的发育起点温度在13.32～14.72 ℃;四川尾尺蛾卵的有效积温为120.82日·度,显著高于其他8种昆虫(45.09～68.30日·度）.研究得到的有效积温回归方程可初步用于9种昆虫发生的预测.

Abstract: Detailed experiments were carried out to investigate the effects of temperature on fecundity of nine lepidopteran species in Tiantong National Forest Park, Zhejiang Province, China. In the temperature range of 19-28 ℃, nine lepidopteran moths laid eggs and the eggs hatched successfully, and the preoviposition period was shortened with the rising of temperature. The largest fecundity of Ourapteryx ebuleata szechuana and other seven lepidopteran species occurred at 22 ℃, while that of Miltochrista ziczac occured at 25 ℃. The period of the embryonic stages of the nine lepidopteran species were shortened with the rising of the temperature. O. ebuleata szechuana had a lower developmental threshold temperature at 9.52 ℃ and a higher effective accumulated temperature of 12082 degreeday, while the other 8 species got the developmental threshold temperature between 13.32 ℃ to 14.72 ℃, and the effective accumulated temperature between 45.09 degreeday to 6830 degreeday. The regressive equation of effective accumulated temperature obtained in the research could be used to preliminarily forecast the occurring of the nine lepidopterans.

Key words: Lepidoptera, egg-hatching, effective accumulated temperature, fecundity.
