近几年来国外对蚊虫的生物防治研究有所发展,现简要作一介绍。 1、病毒(viruses)虹彩病毒(iridBscenf viruses)一般对蚊幼虫感染率很低。感染率比较高的有质多角体病毒(cytopfasmic polyedrous Viruses),但感染的幼虫常常能化蛹,羽化为正常成虫。核多角体病毒(nuclear polyhedrousis Viruses)曾被建议作蚊虫防治剂,但存在只对少数种类感染率高及自然感染率不高的问题。 In recent years, foreign studies on the biological control of mosquitoes have been developed, are briefly introduced. 1, viruses (iridBscenf viruses) The general infection rate of mosquito larvae is very low. The infection rate of cytoplasmic polyedrous virus (cytopfasmic polyedrous Viruses), but the infected larvae often pupate, emergence into normal adults. Nuclear polyhedrousis Viruses have been proposed as mosquito control agents, but there is a problem with high rates of infection and natural infection only for a few species.
