自从Morris等(1954)把生命表方法引用到昆虫自然种群的研究以来,生命表方法逐渐发展成为研究昆虫种群动态的一种重要手段,并在农作物害虫、果树害虫、储粮害虫和卫生害虫的研究上广泛的应用(尹汝湛,1980:Harcourt,1969)。1973年以来,中山大学等在广东四会县大沙公社进行了水稻害虫综合防治的研究,7年的试验结果,原来为害严重的水稻三化螟Scirpophaga incertulas、粘虫Leucania separata、稻褐飞虱Nilaparvata lu-
Since Morris et al. (1954) introduced the life table approach to the study of insect natural populations, the life table approach has evolved into an important tool for studying insect population dynamics and has been widely used in crop pests, fruit tree pests, stored grain pests and hygienic pests Research on a wide range of applications (Yin Ruzhan, 1980: Harcourt, 1969). Since 1973, Sun Yat-sen University and other large sand commune in Sihui County, Guangdong conducted a comprehensive study of pest control, the results of seven years of trials, the original severely damaged rice borer Scirpophaga incertulas, armyworm Leucania separata, Nilaparvata lu -
