一、防治对策及理论依据红铃虫是专以棉花的蕾、花、铃为取食藏身之处,且对青铃最为嗜好。当棉株生长发育到达现蕾时,也就是第一代卵始盛期即将开始刚期。如果这时棉株还没有现蕾,则羽化的成虫由于缺乏食料一般是不会产卵的,即使有时偶尔产一点卵,孵化的幼虫也不能成活,而无法危害棉花。于是形成第一代红铃虫卵在不同类型棉田出现的特点是,
First, the prevention and treatment measures and theoretical basis Red bollworm is a cotton bud, flowers, bells for the hiding place, and the most preference for the green bell. When the cotton plant growth and development to reach the bud, that is, the first generation of eggs is about to start just beginning period.
