摘要
用已受过棉虫为害的棉叶饲养棉铃虫幼虫，其生长发育受到影响。与对照相比，幼虫生长受阻，虫体重较轻，且虫龄越小，阻碍作用越强，幼虫生长期延长，化蛹率和羽化率约有下降。在正常棉株和受害棉株之间，棉铃虫雌蛾产卵明显趋向正常植株，但未能发现幼虫在取食定向反应时也表现出趋性。
The growth and development of cotton bollworm larvae reared on the cottonleaves damaged by cotton pest in advance were suppressed,in comparison with those onthe leaves without damage,the growth of larvae were inhibited and got lighter body一weight,the earlier the instar,the stronger the effect of the inhibition was.The develop-mental duration of larvae was prolonged and their pupation and emergence rates weresomewhat reduced. The female moths prefered to oviposite on healthy cotton plants,rather than on those damaged before, despite it had not been found that the larvae pos-sessed this preference in feeding test of larvae.
