摘要： 利用Y型嗅觉仪研究了水稻挥发物对二化螟初孵幼虫和3龄幼虫的趋性影响。处理包括健康苗与空白对照、二化螟为害苗与空白对照、稻纵卷叶螟为害苗与空白对照、健康苗与二化螟为害苗、健康苗与稻纵卷叶螟为害苗、二化螟为害苗与稻纵卷叶螟为害苗。结果表明，水稻挥发物对二化螟初孵和3龄幼虫都表现出显著的引诱作用。二化螟幼虫对不同处理水稻（健康苗、二化螟为害苗和稻纵卷叶螟为害苗）挥发物之间的趋向选择无显著差异。

Abstract:

The orientational behavior of the 1st- and 3rd- instar larvae of the striped stem borer (SSB, Chilo suppressalis) to the volatiles emitted from rice plants was studied with a Y-tube olfactometer. The following treatments were set: healthy plants vs clean air (HP vs CA), striped-stemborer damaged plants vs clean air (SSB-DP vs CA), rice leaf folder damaged plants vs clean air (RLF-DP vs CA), HP vs SSB-DP, HP vs RLF-DP and SSB-DP vs RLF-DP. The result showed that volatiles from all rice plants had significant attraction to both the 1st and the 3rd instar larvae. The orientational selection of larvae to the volatiles from differently treated rice plants(HP, SSB-DP, and RLF-DP) had no significant difference.
