摘　　要：通过对玉米三点斑叶蝉 (ZyginasalinaMit .)若虫的捕食效应研究表明 ,七星瓢虫 (Coccinellaseptempunc tataL)、多异瓢虫〔Hippodamiavariegata (Goeze)〕和菱斑巧瓢虫 (OenopiaconglobataL)对玉米三点斑叶蝉若虫的功能反应形式均属于HollingⅡ型。Lady beetles were the common predators in corn fields, which occurred in large number and had high control effect. The predatory effect of Coccinella septempunctata L,Hippodamia variegata (Goeze) and Oenopia conglobata L were studied in Xinjiang in 1999～2000. The result showed the predatory functional response of the lady beetles to 3rd 4th instar nymphs belonged to Holling Ⅱresponse. Coccinella septempunctata L adult and larvae respectively prey on 23.4742 and 56.4971 3rd 4th instar nymphs leafhoppers, Hippodamia variegata (Goeze) and Oenopia conglobata L adult respectively prey on 23.6967 and 24.3309 3rd 4th instar nymphs leafhoppers per day.
