昆虫病毒作为一种微生物杀虫剂,正越来越受人们的重视。然而,由于病毒杀虫剂潜伏期长,见效慢,幼虫感染病毒后取食量的变化受到不少学者的关注。Glass(1958)和Chamberlain(1958)用病毒防治红带卷蛾和烟芽夜蛾时发现,使用病毒后,幼虫的死亡率虽可达到100％,但不能减轻对作物的危害。Tanada(1962)使用病毒防治美洲棉铃虫,结果只有在幼虫1、3龄时感染病毒,才能避免对作物的为害。1973年,Harper使用人工饲料定量研究了病毒感染对粉
Insect virus as a microbial insecticide is more and more people’s attention. However, due to the long incubation period of the virus insecticide and the slow response, the change of the food intake of the larvae after being infected by the virus has attracted the attention of many scholars. When Glass (1958) and Chamberlain (1958) used the virus to control the red-bellied moth and the tobacco budworm, it was found that although the mortality of the larvae reached 100% after using the virus, the damage to crops could not be alleviated. Tanada (1962) used the virus to control American Helicoverpa armigera, and as a result, the virus was only infected at the first and third instar larvae in order to avoid crop damage. In 1973, Harper used artificial diet to quantitatively study the virus infection on flour
