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。
In this paper, the functional response of the larvae of Chinese weed to the corn borer eggs and the intraspecific interference effects of the second instar larvae were studied. Studies have shown that, 1-3 instar larvae of the functional response are Holling Ⅱ type. The second-instar larvae ’s interference effect was simulated by Hassell model E = QP ~ (-m), and the result showed that E = 0.3146P ~ (-0.7294) .With the increase of second instar larvae, the predation rate decreased.
