摘要
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。
Functional response of Misumenops tricuspidatus to the larvae of its prey, Heliothis armigera, was studied in laboratory. Functional response of the predator to its prey density was found to be positively correlated with the prey density, and negatively correlated with its own density.
