在室内测定迭球螋（Forficula vicaria Semenov）成虫对棉蚜（Aphis gossypii Glover）的捕食作用。结果表明，迭球螋对棉蚜的捕食功能反应符合 HollingⅡ（1959）型模型，拟合的圆盘方程为Na ＝0．9936 Nt/（1＋0．0041 Nt ）；根据汪世泽等（1988）提出的 HollingⅢ型功能反应新模型Na ＝a·exp（-bN-1t ）拟合，求得日均最大捕食量176．9头，最佳寻找密度92头；利用 Holling（1959）寻找效应与猎物密度关系公式E＝a/（1＋aThNt ），结果表明寻找效应随猎物密度的增加而降低；利用 Hassell （1969）模型 E＝QP -m 和 Beddington（1975）模型 E＝aT/[1＋btw （P-1）]对寻找效应与迭球螋成虫密度之间的关系进行拟合，拟合方程分别为：E＝0．6318 P -1．3693和 E ＝0．7384/（2．2668 P -1．2668）， Beddington 模型更好地反映了寻找效应与迭球螋密度之间的关系；寻找效应与迭球螋密度和棉蚜密度之间的关系用 Beddington（1975）模型 E ＝a/[1＋aThN a ＋btW （P -1）]进行描述，拟合方程：E ＝0．7384/（2．2668 P ＋0．00404 Na -1．2668），寻找效应随迭球螋密度和猎物棉蚜密度的增大而下降。

Predation of Aphis gossypii by Forficula vicaria adults was determined in the laboratory. The results showed that the predator-prey model fitted HollingⅡ(1959):Na=0. 9936Nt/(1+0. 0041Nt). The largest dai-ly predation number was 176. 9, and the best seeking density was about 92 according to Holling Ⅲ new functional response model Na=a·exp(-bN-1t)by Wang Shize et al (1988). The relationships between searching efficien-cy and prey density were studied by using Holling (1959)model:E=a/(1+aThNt), showing that the searching efficiency decreased as the prey density increased. The relationships between searching efficiency and F. vicariadensity were described by Hassell (1969)model E=QP-m and Beddington (1975)model E=aT/[1+btw(P-1)] as E=0. 6318P-1.3693 and E=0.7384/(2.2668P-1.2668), respectively;Beddington (1975)model could de-scribe the relationships between searching efficiency and F. vicariadensity better than Hassell (1969)model. The relationships between searching density and A. gossypii and F. vicariadensities were described by Beddington (1975)model E=a/[1+aThNa+btW(P-1)]. as E=0.7384/(2. 2668P+0. 00404Na-1. 2668), suggesting that the searching efficiency declined when F. vicaria and A.gossypi idensities increased.
