摘要:
普通肉食螨广泛分布于粮库及仓储场所,是理想的天敌资源,对害螨及储粮害虫的卵和低龄幼虫有很好的防治潜能。为明确普通肉食螨对害螨的防控能力,以粗脚粉螨为对象,研究普通肉食螨原若螨、后若螨、雌成螨三种螨态对粗脚粉螨卵、幼螨、若螨和成螨的捕食功能反应。结果表明,普通肉食螨三种螨态对粗脚粉螨各螨态的功能反应均属于Holling Ⅱ型,普通肉食螨三种螨态中,雌成螨对粗脚粉螨卵、幼螨、若螨和成螨的攻击能力最强,攻击系数分别是0.913、1.030、1.017和0.989;普通肉食螨喜食粗脚粉螨幼螨,最大捕食效能为 42.436头/d;在捕食能力方面,除粗脚粉螨卵以外,普通肉食螨对粗脚粉螨的捕食能力大小均为:雌成螨>后若螨>原若螨,普通肉食螨对粗脚粉螨具有很好的防治潜能。本研究为普通肉食螨防治储粮害螨奠定了基础参数,为进一步应用普通肉食螨控制害虫害螨提供参考。

Study on predatory function of Cheyletuseruditus (Schrank) on Acarussiro (Linnaeus)
Abstract:
Cheyletuseruditus (Schrank) is widely existed in grain depots and warehouse, which is an ideal natural enemy resources with control potentialagainst pests and mites, especially for eggs and young larvae.In order to evaluate its biological control potential to Acarussiro (Linnaeus), functional response analyses were conducted of three C. eruditusstages, protonymph, deutonymph and female adult to four Acarussiro stages, eggs, larve, nymphs and adult.The results showed that the predation function of C.eruditusprotonymphs, deutonymphs and female adult all belonged to the HollingⅡtype to four stages of Acarussiro. The predation ability of female adult was the highest, and its attacking efficiency on different stages of Acarussiro was 0.913 (egg), 1.030 (larva), 1.017 (deutonymph), 0.989 (adult) respectively. The female adult of C.eruditus preferred to the larvae, with the maximum predatory efficiency 42.436 larvae per day. In terms of the predatory capacity of C.eruditus to Acarussiro, female adult showed the highest potential in preying different stages of Acarussiro except for the eggs, then was deutonymph. C.eruditus was the mostpotential native Phytoseiid species that might be used in Acarussiro control. This study laid a foundation parameter for the control of stored grain pest and mites by C. eruditus, and provided a reference for the further application of C. eruditus to control pest insects and mites.
