摘　　要：采用水蒸气蒸馏法分别提取艾蒿(Aremisia argyi)、凌霄(Campsis grandiflora)、紫茉莉(Mirabilisjalapa)、丁香(Syringa oblata)的挥发性物质,通过室内试验研究提取物对菜粉蝶(Pieris rapae L.)产卵行为的影响。结果表明4种提取物对菜粉蝶具有产卵忌避作用,艾蒿对菜粉蝶的产卵忌避作用最强,平均忌避率为65.7%,其次是紫茉莉,凌霄和丁香的产卵忌避作用相对较弱;随着放置时间的延长,各处理忌避效果均逐渐减弱,处理后24 h的忌避作用最强。艾蒿和紫茉莉提取物对菜粉蝶产卵正反比影响相对较强,产卵正反比分别为29.7%和24.7%,凌霄和丁香提取物对菜粉蝶产卵正反比影响作用相对较弱,产卵正反比分别为12.3%和18.7%。To evaluate the control effects of non-host plants on Pieris rapae L., bioassays were conducted to investigate the oviposition deterrent effects of 4 non-host plants such as argy wormwood（Artemisia argyi）, Chinese trumpet creeper （Campsis grandiflora）, marvel of Peru （Mirabilis jalopa）, and elove（Syringa oblata） on the butterfly in laboratory. Indoor bioassay re- sults showed that four kinds of plants extracts had oviposition deterrent effects on P. rapae. Oviposition deterrent activity of argy wormwood was strongest which the oviposition deterrent rate was 65.7%, followed by marvel of Peru, and that of Chi- nese trumpet creeper and clove were weaker. Deterrent activity of the four kinds of plant extracts was decreased with the time increased, and it was strongest at 24 h. Extracts of wormwood and marvel of peru had effect on oviposition sites of P. rapae, the average backs to front rates were 29.7% and 24.7% respectively. However Chinese trumpet creeper and clove extracts had weak effect on oviposition site of P. rapae, the average ovipositions back to front rates were 12.3% and 18.7% respectively.
