摘要
为有效控制枣树黄刺蛾的为害,连续几年对该虫的发生与防治进行了系统研究。研究结果看出,黄刺蛾在兰溪市 1 年发生 2 代,并以老熟幼虫在枝干上结茧越冬,在防治策略上采取主治第 1 代,控制第 2 代,在冬季剪除枝干上黄刺蛾的越冬茧,并在 1~2 龄幼虫期喷药,能收到预期效果。
To effectively control damage by Cnidocampa flavescens in Zizyphus jejuba, systematical studies on occurrence and control for years in succession indicated that C.flavescens had 2 generations a year in Lanxi, overwintered with cocoon by adult in branches. Measures like wiping out the first generation, controlling the second, cutting cocoon in winter, spraying pesticide during 1-2-instar had good effect.
