摘要: 试验研究了不同饥饿程度的龟纹瓢虫雌、雄成虫对烟蚜的捕食作用.结果表明,不同饥饿程度的龟纹瓢虫雌、雄成虫对烟蚜捕食的功能反应均为Holling Ⅱ型,雌成虫的瞬间攻击率a大于雄成虫;不同饥饿程度的龟纹瓢虫雌、雄成虫在24h内对烟蚜的捕食量差异不显著;雌成虫捕食量大于雄成虫;饥饿时间愈长,烟蚜密度愈大,雌雄成虫间捕食量差异愈显著;未饥饿的龟纹瓢虫雌、雄成虫在24h内对烟蚜的捕食行为集中在6◇00~18◇00,雌雄成虫间的捕食速度(V)差异不显著;饥饿48h的龟纹瓢虫雌、雄成虫在24h内对烟蚜的捕食行为集中在试验开始后的0~4h,雌雄成虫间的捕食速度(V)差异也不显著.

Abstract: The study showed that the functional response of predation on M.persicae by the female and male adults of P.japonica with different extents of starvation belonged to the type of Holling Ⅱ.Female adults had a larger attacking rate than male adults, but the predacious amount of M.persicae by female and male adult predators of different extent of starvation within 24hrs had no significant difference.The predacious amount by female adult was larger than that of male.The significant difference of predacious amount between female and male adults increased with the time of their starvation and the prey density.The predation by unstarved female and male adult predators on M.persicae in 24 hours was concentrated at 6◇00~18◇00 and the predation rate (V)between female and male adults had no significant difference.The predation by starved female and male adults for 48h on the prey in 24 hours was at 0~4 hours after the experiment started, and the predation rate(V)between female and male starved adults had no significant difference either.
