| 摘 要： | 本实验应用嗅觉仪测试了端尖食植瓢虫对分布在山东境内木犀科常见植物,近缘科黄杨科、槭树科、大戟科和金缕梅科常见植物,以及发生地常见植物的选择性。结果表明:木樨科的白蜡树对其有明显的招引,表明端尖食植瓢虫有可能会对其取食、危害;小叶女贞有可能成为其潜在的危害对象,其余木樨科、黄杨科、槭树科、大戟科和金缕梅科的山东省常见的树种,以及瓢虫发生地周围林木则对排斥有明显的排斥作用,表明这些植物不会成为端尖食植瓢虫的危害和寄主对象。这一结果表明其寄主扩散范围有限。

| Abstract: | The selectivity of Epilachna quadricollis to Oleaceae, Buxacea, Aceraceae, Euphorbiaceae. Hamamelidaceae and other plants were tested with Y-tube olfactometer in the experiment. The result showed that Fraxinus chinensis could at tract E. quadricollis obviously. L. quihoui is the potential hazard host of E. quadricollis. Oleaceae, Buxacea, Aceraceae, Eu phorbiaceae, Hamamelidaceae and other trees in Shandong Province were expelled; Epilachna quadricollis did not feed on these plants. The result showed that the ladybird diffusion risk is seldom. |
