摘　　要：在室内研究不同温度(19℃、22℃、25℃、28℃和31℃)对金银花尺蠖幼虫取食量、取食速率、近似消化力和食物利用率的影响。结果表明,较低温度(19℃和22℃)时金银花尺蠖幼虫的取食量和取食速率比较小,近似消化力和食物利用率比较低,随着温度的升高,金银花尺蠖幼虫的取食量、取食速率、近似消化力和食物利用率均逐渐增大,到25℃时达到最大,分别为607.36 mg、27.47 mg/d、58.45%、20.81%;高温(31℃)时取食量明显减少,取食速率、近似消化力和食物利用率明显降低。根据所建立的平均取食量、取食速率、近似消化力、食物利用率与温度间的回归模型计算得出,金银花尺蠖幼虫取食量、取食速率、近似消化力和食物利用率最大的最适温度分别为26.15℃、25.02℃、25.38℃和25.30℃。The effects of temperatures（ 19℃,22℃,25℃,28℃ and 31℃） on the feeding capacity,feeding rate,approximate digestion and food utilization efficiency of Heterolocha jinyinhuaphaga Chu larvae was studied in the laboratory. The results showed that temperatures affected them significantly. At low temperatures（ 19℃ and 22℃）,its feeding capacity,feeding rate,approximate digestion and food utilization efficiency were lower. With the increasing of temperature,the feeding capacity,feeding rate,approximate digestion and food utilization efficiency increased gradually. At 25℃, they reached maximum,which were 607. 36 mg,27. 47 mg / d,58. 45% and 20. 81%,respectively,and decreased at high temperatures. According to the established regression model on average feeding capacity,feeding rate,approximate digestion,food utilization efficiency and temperatures,the optimum temperature for the biggest feeding capacity, feeding rate, approximate digestion and food utilization efficiency were calculated as 26. 15℃,25. 02℃,25. 38℃ and 25. 30℃,respectively.
