棉铃虫生物学习性与发生为害关系

阐述了棉铃虫营养生态学特性、生物学习性与其发生为害的关系。饲料中粗蛋白质量分数为 9.7%、糖质量分数为12 .5 %时对棉铃虫有最佳的营养效应 ,该饲料中碳水化合物对蛋白质的比率约为 1.3 ,与棉铃中两者的比例十分接近 ,这与棉铃虫偏嗜棉铃的特点相一致 ;同时棉铃虫的一般生物学习性 ,生物学高潜能性及大发生年卵的分布特点是造成棉铃虫长盛不衰的重要原因

Research Progress the Relation between the Biological Habit and Qceu rrence of Cotton Boll Worm

The factor affecting the damage oceurrence of cotton boll worm was various.The relationship between ecological and biological habit and the damage ocearrence of cotton boll worm was analyzed.The best nutrition food for cotton boll worm was the feed containing 9.7% protein and 12.5% sucrose,which rate of C:N is same as that of cotton boll.Thus,it was possible for cotton boll worm to eat cotton ball.And also,the habit of cotton boll worm and the charaetor of its egg distribution were another reason of the frequeacy occurrence of cotton boll worm.
