1988年在实验室内人工条件下,对三突花蛛捕食棉铃虫幼虫的功能反应进行了初步研究。三突花蛛的捕食功能反应是随猎物密度的增加而增大,而随其自身密度的增加而减少,随两者密度的增加,相互干扰越显著,捕食作用效应下降。建立了参数方程和模拟模型。该参数方程能在一定程度上描述雌成蛛对棉铃虫初孵幼虫至3龄幼虫的捕食作用。 In 1988 under artificial conditions in the laboratory, preliminary studies on the functional response of the three herbivores to predation on cotton bollworm larvae. The predation function response of the three spider mites increased with the increase of the density of the prey, but decreased with the increase of their own density. As the two densities increased, the mutual interference was more significant and the predation effect decreased. Established the parametric equation and simulation model. This parametric equation can describe the predation of female adult spiders to 3rd instar larvae of newly hatched larvae of cotton bollworm to some extent.
