There were ants, lacewings, ladybirds, and beetles. 里面有蚂蚁,草蜻蛉,瓢虫,和甲虫。
The main factors interfering with community similarity were producing area, geographical region, species and quantites of predacious ladybirds. 影响群落相似性的主要因子为产区、地理位置、捕食性瓢虫的种类和数量。
Among the functional groups of natural enemies, ladybirds had a stronger ability of recovery, while spiders and parasitoids were weaker. 在天敌功能团中,瓢虫类恢复能力较强,蜘蛛类与寄生性天敌类较弱。
The distribution of ladybirds, green lacewings and spiders during cotton growth period was: the trap corn> the treatment cotton field> the contrast cotton field. 在棉花生长期间,瓢虫、蜘蛛和草蛉三者的总数均为玉米诱集带>处理棉田>对照棉田。
Numerical cladistic method was used for analyzing the phylogeny of ladybirds, based upon adult and larval characters. 根据成虫和幼虫的特征,应用数值支序方法探讨瓢虫科的系统发育。
Based on the systematical investigation of population dynamics of predacious ladybird in different cotton agroecosystem, the energy flow for predacious ladybirds was analyzed by the way of ecological energetic. 在系统调查棉田捕食性瓢虫种群数量动态的基础上,应用生态能学的方法,分析并比较了不同播种期、套间作等农业措施对棉田捕食性瓢虫控害功能的影响。
Predacious natural enemies included ladybirds, lacewings, predacious bugs, rove beetle and spiders, but populations were low and lagged behind the population peaks of insect pests. 捕食性天敌主要有瓢虫、草蛉、食虫蝽、隐翅虫和蜘蛛,但是发生数量低、数量高峰明显滞后于害虫数量高峰。
The relationship of predatory and competition between leafhoppers and ladybirds ( Coccinellidae), spiders and Microgramme spp., spiders and hawthorn spider mites, hawthorn spider mites and Microgramme spp., Microgramme spp. and gall midge ( Cecidomyiidae) were obvious due to the large niche overlap between them. 叶蝉与瓢虫、蜘蛛与小薪甲、蜘蛛与山楂叶螨、山楂叶螨与小薪甲、小薪甲与瘿蚊的二维生态位重叠较大,说明它们之间的捕食和竞争关系非常明显。
The surface showed clear signs of black stripe before the hatch of eggs; larva: The first instar larvae of the two ladybirds were not significantly different. 将孵化时卵表面呈现黑色条纹;2种瓢虫的1龄幼虫没有明显区别。
