美国防治棉红铃虫仍以施杀虫剂为主要手段。全国农药量的一半用于棉花,其中大部分杀虫剂用于防治棉红铃虫和棉铃象甲。由于大量使用杀虫剂,天敌受到伤害,环境遭污染,而且费用增加。因此,近年来研究人员致力于研究通过管理栽培措施,防治棉红铃虫的危害。 The United States cotton bollworm control insecticide is still the main means. Half of the national pesticide is used in cotton, most of which are used to control cotton bollworm and boll weevil. Due to extensive use of pesticides, natural enemies are harmed, the environment is polluted, and costs increase. Therefore, in recent years, researchers have devoted themselves to studying and controlling the harm caused by pink bollworm by managing cultivation measures.
