摘要
利用Y型嗅觉仪测试红环瓢虫对其生境中害虫虫体气味的趋性反应。结果表明,红环瓢虫成虫对草履蚧幼虫和虫卵有明显的趋性;其幼虫对草履蚧雌成虫有明显趋性;且瓢虫对害虫的趋性反应与害虫虫体气味浓度相关,天敌昆虫必须达到一定数量时才表现出明显的趋性。
In this study,the behavioral tests of Rodolia limbata Motschulsky toward pests odor in their habitat are carried out,the results showed：the adult of R.limbata displayed significant tendency to larva of D.corpulenta and eggs ; the larva of R.limbata showed significant tendency toward female aduh of D.corpulenta.All the response of tendency tests of the natural enemies mentioned above was highly related to the density of pests odor,only when the density had reached certain level would the natural enemies show significant tendency.
