| 摘 要： | 本文探讨了番茄(Lycopersicum esculentum)、苦楝(Melia aze-darach)、黄花蒿(Artemisia annua)和甘野菊(Dendranthema boreale)等植物对菜粉蝶(Artogeia rapae)幼虫嗅觉和拒食的影响。在嗅觉器内,幼虫对植物气味有一定嗅觉反应,说明嗅觉在一定程度上与食物选择有关;但忌避与拒食间并不都呈直线关系,说明嗅觉不是该幼虫取食与否的唯一因素。所测试的试样均有一定拒食作用,其中番茄枝叶抽提物在拒食、减食方面表现出相当强的活性,值得进一步研究。

| Abstract: | Airflow olfactometer test for Artogeia rapae larvae showed that,to a certain extent,the larvae could discriminate various plant odors with olfactory organ(s).But not all the plant extracts used in this assay posse- ssed of same activities in food selection behavior as well as in olfactory responses.Such a phenomenon likely implys that the olfactory signals might not be the unique factor in food selection of the larvae. Most of the plant extracts used had antifeeding activities.Among these the alcoholic extr... |
