三突花蛛对亚洲玉米螟幼虫的捕食作用
Predatory Function of Misumenopos tricuspidata on Larvae of Ostrinia furnacalis
摘要
Abstract
The predation function and searching response of Misumenops tricuspidatus on 2nd instar larvae of Ostrinia furnacalis (Guenee) were studied. The predation functional response of Misumenops tricuspidatus on larvae of Ostrinia furnacalis were fitted well with Holling' s type H model, Na = 1. 1359N/( 1+0. 09534N) , and the daily maximum number was 64.35. The searching rate model of Misumenops tricuspidatus could be described by Hassell - Varley model as E =0.4063P-0.5891 and by the Beddington model as E =0. 4026/[ 1+0.2382 (P -1) ]. The two models showed that the searching rate of Misumenopos tricuspidata decreased with the increase of predator' s density.关键词
