棉红铃虫Pectinophra gossypiella Saunders)是一种世界性棉花害虫,也是我国长江流域锦花生产上的主要害虫之一。从三十年代起,国内外许多学者对锦红铃虫的生物学,生态学特性以及防治技术等方面进行了许多研究。自1954年以来,生命表技术已成为国际上盛行的研究课题,并在许多害虫的研究上广泛应用,但关于红铃虫自然种群生命表的研究尚未见报道。从1980年起,我们开展了棉红铃虫自然种群生命表的研究工作,旨在探讨此项工作的研究方法,进而掌握红铃虫自然种群变动规律及其关键因子(Key factor),为制定红铃虫防治策略,提高综合防治水平,提供科学依据。
Cotton bollworm Pectinophra gossypiella Saunders) is a worldwide cotton pest and is also one of the major pests in the production of Jinhua in the Yangtze River valley in China. Since the 1930s, many scholars at home and abroad have carried out many researches on the biology, ecological characteristics, prevention and treatment of Rhodospirillum polygamis. Since 1954, life table technology has become an internationally prevalent research topic and has been widely used in many pests. However, there is no report on the life table of natural populations of Brady oryzoonia. Since 1980, we have carried out the research on the natural population of pink bollworm, which aims to explore the research methods of this work and to understand the natural population dynamics and the key factor of pink bollworm. In order to develop Red bollworm prevention and control strategies to improve the level of comprehensive prevention and control to provide a scientific basis.
