摘要
青翅蚁形隐翅虫Paederus fuscipes Curtis乃农田常见的一种捕食性天敌,是害虫综合防治中可资保护利用的天敌种类。关于青翅蚁形隐翅虫对害虫的捕食作用,G.V.Manley(1977)对西马来西亚水稻叶蝉作过研究。国内祝长青(1984)进行了对玉米、豆、棉、蔬菜、甘薯等害虫的捕食量观察。湖北、湖南、浙江等省资料,零星涉及捕食的对象和捕食量。
Paederus fuscipes was the common predator in the fields, which occurred in large number and had high control effect. The predatory effect of P. fuscipes was studied in Sa County and Fuzhou of Fujian province in 1980—1986.P. fuscipes could prey on several species of main rice pests, and had a large predatory number on small pests such as rice planthopper,rice leafhopper, first appearance larva of paddy stem borer and rice thrip. It could respectively prey on 49 first appearance larvae of paddy stem borer, 24 2nd-instar nymphs of white back planthopper, 23 1st-instar nymphs of Nephotettix cinctlceps at maximum number per day. The predatory number of the female was more than that of the male. The resistance to food of the female was 3-12 days, and the male was 3—9 days. The predatory functional response of the female adults to 3rd—4thirtstar nymphs and female adults of white back planthopper belonged to Type Ⅱ response.
