摘要
在大试管内研究了草间小黑蛛对褐稻虱的捕食反应,测定了褐稻虱虫龄及温度对功能反应的影响,并建立了同时考虑这2个因子影响的 Holling 圆盘方程.还研究捕食者个体间的相互干扰反应,并建立草间小黑蛛对猎物密度和自身密度的共同反应模型.
Dwarf spider Erigonidium graminicolum is a key enemy to paddy brown planthopper Nilapavata lugens(BPH).The functional responses of dwarf spider to BPH have been studied in present paper.The effects of the prey-age and temperature on the response have been determined respectively, and the model considering the intergrated influence of the two factors has been constructed.Meanwhile,the effect of the interference among the spi- der's individuals has been studied and the model of the intergrated response of the spider to the density of itself and the prey has been built.
