摘要: 大草蛉雄成虫在捕食过程中,麦秆数越多,环境阻力越大,空间异质性越复杂,捕食作用率越低;大草蛉雄成虫种内干扰作用系数为0.9390,大草蛉雄成虫与龟纹瓢虫幼虫之间的种间干扰作用系数为0.8722,前者大于后者;竞争强度I与天敌P之间的关系为I=0.0640+1.11271gP.

Abstract: The more wheat stalks the adult Chrysopa septempunctata encountered, the more interference was met during the predation of C. septempunctata, which means that the predation efficiency was low when the spatial heterogeneity was complex. The coefficient of mutual interference within C. septempunctata was 0.9390, and that between C. septempunctata and Propylaea japonica was 0.8722. The frontier was greater than the latter. The correlation of competition strength(I) and the number of natural enemy (P) could be described as I=0.0640+1.11271gP.

Key words: Mutual interference, Spatial heterogeneity, Chrysopa septempunctata, Predation, ecosystem services, urbanization, InVEST model, driving factor, CLUE-S model
