雨尺蠖Semiothisa pluviata(Fabricius)在江西赣州以幼虫危害黑荆树Acaciamearnsii叶片,一年发生4代,以蛹越冬,世代重叠。5月上旬出现第1代幼虫,危害最盛为第3代幼虫。主要天敌有姬蜂Diplozon sp.、跳小蜂(学名待定)及白僵菌,还有大山雀Parus msjor commixtus(Swinhoe)、红尾伯劳Lanius cristatus lucionensis Linnaeus等鸟类。用2000—3000倍敌杀死或800—1000倍灭杀毙喷雾,防治效果在90%以上。
Semiothisa pluviata (Fabricius) The larvae of Acaciamearnsii are endangered by the larvae of Acaciamearnsii in Ganzhou, Jiangxi Province. Four generations occur each year, and the pupae overwinter. The generations overlap. The first generation of larvae appeared in early May, the third-generation larvae are the most damaging. The main natural enemies are the Bombyx Diplozon sp., Jumping bees (scientific name to be determined) and Beauveria bassiana, as well as the great tit Parus msjor commixtus (Swinhoe), red tail shrike Lanius cristatus lucionensis Linnaeus and other birds. With 2000-3000 times the enemy killed or 800-1000 times kill kill spray, control effect in more than 90%.
