| 摘 要： | 在6个恒温下研究普通肉食螨Cheyletus eruditus(Schrank)不同螨态对椭圆食粉螨Aleuroglyphus ovatus(Troupeau)的功能反应。结果表明,普通肉食螨不同螨态对椭圆食粉螨的功能反应均属于HollingⅡ型,其中雌成螨的捕食能力最强,其次是雄螨、若螨、幼螨;在各温度处理中,雌成螨在28℃时具有较高的捕食功能;普通肉食螨在16℃的低温状态下捕食功能很低,仅有雌螨对猎物有捕食行为;在猎物密度不变的情况下,普通肉食螨捕食猎物的数量随自身密度的增加而下降。

| Abstract: | The predation of Cheyletus eruditus(Schrank) on Aleuroglyphus ovatus(Troupeau) was studied at 6 constant temperatures.The results showed that all functional response of C.eruditus in different developmental stages to A.ovatus can be described as HollingⅡtype.Among all stages and temperatures,female adult was the most efficient predatory stage at 28℃,Only female adult preyed on A.ovatus at 16℃.The density of predator affected the predatory ratio,in which the number of predation was slowly decreased with the increased density of predator. |
