昆虫病毒杀虫剂是联合国粮农组织和世界卫生组织早在上个世纪八十年代开始倡导使用,列入21世纪重点开发对象并要求世界各国推广应用的最新生物防治技术。它是一种在自然界里自然生存的,且对害虫极具致命力的昆虫病原体病毒,经过多种分子生物学手段进行分离、提纯、复制、复配而成。这种人造“虫瘟”的全新概念源于20世纪五十年代后期,为限制当时迅猛发展的高毒、高残留化学农药而提出。
Insect virus Insecticide is the newest biocontrol technology that FAO and WHO started to advocate in the eighties of the last century, which is included in the key development target of the 21st century and requires popularization and application in all countries in the world. It is a kind of insect pathogen virus that naturally survives in nature and is extremely lethal to pests. It is separated, purified, duplicated and complexed by various molecular biological means. This new concept of artificial “worm blast” originated in the late 1950s and was put forward to limit the rapid development of highly toxic and high-residue chemical pesticides at the time.
