摘要
绿盲蝽是江苏南通地区为害棉花的重要害虫。本文将绿盲蝽卵的发育过程分为4级,对各级的颜色与形态特征进行了描述,并明确了相应的发育历期。田间通过二代绿盲蝽卵量与发育级别的调查,结合发育历期资料,可准确预测二代2、3龄若虫的发生盛期。
Apolygus lucorum is the important cotton pest in Nantong, Jiangsu Province. The developmental period of eggs were divided into 4 stages, the egg color and morphology were described, and development duration of each stage was investigated. Through field survey of egg densities and development stages, combining with the da- ta of development duration we can forecast the perk period of the 2nd and 3rd instar nymphs in the second genera- tion of Apolygus lucorum.
