捕虱管蓟马的捕食、交配和产卵行为

观察了捕虱管蓟马的多种行为，认为该虫的日常行为为取食、行走、搜索、休息、交配和产卵；对所试验的5种害虫的喜好程度依次为椭圆蚧卵，柑桔木虱卵、褐圆蚧卵、柑桔粉虱卵、桔全爪螨若虫，褐圆蚧若虫、桔全爪螨卵、椭圆蚧若虫、柑桔木虱一龄 若虫，除柑桔木虱一龄若虫外，取食差异不显；捕虱管蓟马取食卵的量比若虫多，经T－检验分析，两无明显差异；室内饲养蓟马和田间采获蓟马的行为，及各行行为间差异，通过二因素方差分析显示不显；不同虫态蓟马取食时间长短依次为雌成虫、雄成虫、若虫、在食物充足的情况下，不同虫态之间几乎没有竞争，偶有成虫捕食幼虫现象发生。对该虫的交配行为及产卵行为作了详细的观察，发现雌蓟马成虫和雄蓟马成虫都多次交配；雄虫之间的性竞争十分激烈，而雌虫之间几乎没有竞争。

Studies on preying, mating and oviposition of Aleurodothrips fasciapennis (Franlkin)

The diurnal activities of the predatory thrip Aleurodothrips fasciapennis (Franlkin) were observed. Among the five preys, the thrip preferred to the eggs of Aspidiotus destructor (Signoret), and then to the eggs of Diaphorina citri (Kuwayama), eggs of Chrysomphalus aonidum (Linnaeus), eggs of Dialeurodes citri (Ashmead), larvae of Panonychus citri (McGregor), larvae of Chrysomphalus aonidum (Linnaeus), eggs of Panonychus citri (McGregor), larvae of Aspidiotus destructor (Signoret) and the first instar larvae of Diaphorina citri (Kuwayama). By the mean of ANOVA there were no significant difference between each two preys except the first instar larvae of Diaphorina citri (Kuwayama). The difference between eggs and larvae consumed by the thrip was insignificant through T-test, though the thrip consumed more eggs than larvae. The behavior of thrips reared in the laboratory was similar to thrips collected from field. Adult females feed on more preys than adult males, and adult males more than larvae. The mating and ovipositing behavior was studied too.
