In observation-cage experiments some new contact kairomones for the egg parasiteTrichogramma evanescens Westwood are demonstrated.T. evanescens females search significantly longer on cabbage leaves treated with the wing scales of two hosts,Pieris brassicae L. andP. rapae L. Further, egg washes ofP. brassicae containing an oviposition deterrent pheromone for the butterflies, were found to have a contact-kairomonal effect on the parasite.T. evanescens females search significantly longer on cabbage leaves sprayed with a methanol or water wash ofP. brassicae eggs than on leaves treated with the solvent only.
在观察笼实验中,证明了一些新的接触信息素对卵寄生蜂拟澳洲赤眼蜂有引诱作用。拟澳洲赤眼蜂雌蜂在处理过寄主菜粉蝶和萝卜蚜的甘蓝叶片上停留的时间显著更长。进一步发现,含有蝴蝶产卵抑制剂信息素的菜粉蝶卵洗出液对寄生虫有接触性引诱作用。与仅用溶剂处理的叶片相比,拟澳洲赤眼蜂雌蜂在喷洒了甲醇或水清洗的菜粉蝶卵的甘蓝叶片上停留的时间显著更长。
