| 摘 要： | 桑皱鞘叶甲越冬成虫在湖桑和杂交桑桑园土层 30～ 50cm深处分布最多 ,分别占总虫数的65 0 7%和 65 92 % ,显著高于其它深度土层的成虫数 ;其次是 1 0～ 30cm深处 ,分别占 2 1 69%和 34 0 8% ;0～ 1 0cm以内无越冬成虫分布。越冬成虫 4月中旬开始出土 ,4月下旬大量出土 ,出土成虫数占总成虫数的 80 %以上。田间成虫 4月中旬开始为害 ,4月底到 5月上旬是发生和为害的高峰期。夏伐对桑皱鞘叶甲的成虫数量有显著的抑制作用。

| Abstract: | The mulberry beetle, Abirus fortunei (Baly),overwintered under ground in mulberry fields.65.07% and 65.92% of the total hibernating adults were distributed over 30～50cm underground in common mulberry fields and hybrid mulberry fields respectively,while the ratios of adults of 10～30cm underground were 21.69% and 34.08%.The hibernating adults emerged out of land and gnawed mulberry leaves from middle April,and more than 80% of the adults came out in late April.Damaging peaks occurr from late April to early May.Summer cutting of mulberry branch could restrain significantly population density of the adults. |
