同种幼虫踪迹对未受孕异色瓢虫雌虫行为的影响

Effects of Conspecific Larval Tracks on Non-gravid Female of Harmonia axyridis

为探明幼虫踪迹对食蚜瓢虫取食和交配的影响,通过室内笼罩试验方法,研究了同种幼虫踪迹对未受孕雌虫停留时间和交配行为的影响。结果表明:幼虫踪迹对未受孕交配雌虫的停留时间没有显著的影响,食物条件对未受孕雌虫停留时间的影响也不明显,未受孕雌虫与雄虫的交配很少发生在蚕豆苗上,交配位置的选择具有一定的随机性。

Effects of conspecific larval tracks on staying time and mating behavior of non-gravid female of H.axyridis were investigated in this paper hy indoor enveloping test method. The results showed that the effect of larval tracks on non-gravid female of H. axyridis was not signifi- cant. As the same result, there was also no effect of food conditions on non-gravid female of H.axyridis. The mating site between the non- gravid female and male were random, and rarely took place on plants.
