摘　　要：本文研究了中华草蛉幼虫对玉米螟卵的功能反应及2龄幼虫的种内干扰效应。研究表明,1～3龄幼虫的功能反应均属Holling Ⅱ型。二龄幼虫的干扰效应用Hassell模型E=QP^(-m)模拟,得出E=0.3146P^(-0.7294),随着2龄幼虫密度的增大,捕食作用率随之下降。The functioual responses of 1st-3rd instar larvae of C. sinica to the eggs of O.furnacalis and the mutural interference among the 2nd instar larvae were investigated in thelaboroctory. The results showed that the fanctional respunses all belong to Holling's typeⅡ. The mutural interference can be described by Hassell model as E=0. 3146P^(-0.7294).
