摘　　要：研究了鳞翅触足螨雌雄成螨对腐食酪螨在6个恒温状态下的功能反应。结果表明鳞翅触足螨雌、雄成螨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强于雄成螨;在各温度处理中,雌成螨在28℃时具有较高的捕食效能;鳞翅触足螨12℃的低温状态下捕食效能较低;猎物密度不变的情况下,鳞翅触足螨捕食猎物的数量随自身密度的增加而下降。The predation of Cheletomorpha lepidopterorum （Acari： Cheyletidae ） on Tyrophagus putrescentiae （Acari：Acaridae） has been studied at six constant temperatures. The results showed that all the functional response of C. lepidopterorum on T. putrescentiae were the Holling Ⅱ functional response. The adult female was more efficient than the adult male. Among all stages and temperatures, adult female was the most efficient predatory stage at 28 ℃. At 12℃, C. lepidopterorum had a low predatory efficiency. The predator＇ s density affected its preying ratio and the preying ratio decreased with the increasing predator＇ s density.
