摘要
经过彭泽县两年的调查,棉铃虫的发生以山区最严重,平原次之,丘陵区最轻。发生情况也与农业措施有密切关系,如轮作间作、肥料和农药的施用、打顶整枝等等。最后对棉铃幼虫防治提出一些建议。
Through two years’ investigated in Pangze county,Jiangxi provmce,it is found that theoccurrence of bollworm(Heliothis armigera)is the heaviest in the mountain area, Secondaryin the plain and the lightest in hills area. It is also closely related with the cultural practice,such as crop rotation, fertilizer and pesticide application top and tiller cutting and so on.
