摘要： 用离心法、蒸馏法、冷凝法和吸附法从12个绿豆品种和5个棉花品种植株中提取145份挥发物。用嗅觉仪测定螟黄赤眼蜂对提取物行为反应结果,表明协同素主要来自匍匐型绿豆品种,并主要由吸附法提取获得,活性物质主要存在于叶片中,并随生长期的增长而增加。绿豆植株提取物对螟黄赤眼蜂和玉米螟赤眼蜂均有显著引诱作用。螟黄赤眼蜂对非挥发性提取物没有明显反应。

Abstract: A total of 145 volat ile ex tracts were made from 12 varieties of mung bean and 5 varieties of co ttonplants using the cent rifugation,distillation,condensation and head-space methods.The responses of Tr ichogramma chilonis females to the plant ex tracts w ere evaluated using a 4-source olfactometer chamber.Extractsmade using the head-space method show ed the g reatest number of sig nificant responses of wasps.Synomoneswere mainly f rom creeping ty pe mung bean plants.Leaf ex tracts f rom creeping type mung bean were themost at tractive.Differences occurred betw een mung bean plants of different ages.Tr ichogr amma ostr inia andT.chi lonis show ed similar att ractiveness to creeping type mung bean leaf ex tracts.T.chi lonis wasps did notshow any response to non-volatile ex tracts.
