摘　　要：[目的]探讨温度对黑点切叶野螟发育和取食量的影响,为利用黑点切叶野螟防治空心莲子草提供基础数据。[方法]以空心莲子草为食料,系统研究了不同温度对黑点切叶野螟幼虫发育历期、取食量和日平均取适量的影响。[结果]在试验温度范围内,随温度的升高,黑点切叶野螟幼虫的发育历期缩短,取食量增加,日平均食叶量增加。在17、22、27、32℃恒温下幼虫的历期分别为(53.84±2.70)、(22.02±0.74)、(14.48±0.08)、(10.97±0.57)d,取食量分别为(51.85±11.18)、(229.07±53.41)、(323.71±111.37)、(174.76±35.76)mg,日平均取食量分别为(0.96±0.21)、(10.40±2.42)、(22.36±7.69)、(15.93±3.26)mg/d。当温度达到37℃后,黑点切叶野螟无法完成生活史。[结论]综合研究结果来看,黑点切叶野螟的最适发育温度为27℃。[Objective] The aim was to explore effects of temperature on development and leaf consumption of Herpetogramma basalis( Walker) to provide reference for controlling Alternanlhera philoxeroiders( Mart.) by using Herpetogramma basalis( Walker). [Method] Development duration,leaf consumption and daily leaf consumption of Herpetogramma basalis( Walker) under various temperatures on a Alternanlhera philoxeroiders( Mart.) diet were studied. [Result] Results showed that within the experimental temperatures( except 37 ℃),the development duration decreased,leaf consumption and daily leaf consumption were increased with the increase of temperature. At the constant temperature of 17 ℃,22 ℃,27 ℃,32 ℃,respectively,the development duration of larvae were( 53. 84 ± 2. 70) d,( 22. 02 ± 0. 74) d,( 14. 48 ±0. 08) d and( 10. 97 ± 0. 57) d,respectively; the leaf consumption were( 51. 85 ± 11. 18) mg,( 229. 07 ± 53. 41) mg,( 323. 71 ± 111. 37)mg and( 174. 76 ± 35. 76) mg,respectively; the daily leaf consumption were( 0. 96 ± 0. 21) mg,( 10. 40 ± 2. 42) mg,( 22. 36 ± 7. 69) mg and( 15. 93 ± 3. 26) mg,respectively. If the experimental temperature was more than 37 ℃,Herpetogramma basalis( Walker) could not finish life history. [Conclusion] The most suitable growth temperature for Herpetogramma basalis( Walker) is 27 ℃.
