竹箩舟蛾是竹子的重要食叶害虫 ,分布于我国南方产竹各省 ,在浙江省 1a 3~ 4代 ,均以蛹于土表下越冬。成虫发生期分别为 4月上旬~ 5月上旬、6月上旬~ 7月上旬、7月下旬~ 8月下旬、9月下旬~ 10月中旬。幼虫危害期分别为 4月下旬~ 6月中旬、6月中旬~ 8月上旬、8月中旬~ 10月上旬 ,以第 3代蛹越冬者幼虫可延至 10月下旬 ,第 4代为 10月中旬、11月下旬。第 3代幼虫各龄食叶量分别为 1.57、7.73、16.36、57.0 2、579.78cm2 ,幼虫期共取食竹叶 662 .4 6cm2 。雌性幼虫期食叶量比雄性多 12 %~ 15% ,每头成虫产卵量为 161~ 2 86粒。天敌有赤眼蜂、黑卵蜂、姬蜂、寄蝇等。并提出了相应的防治方法 Bamboo sparrow moth is an important leaf-feeding insect pests, distributed in the southern provinces of bamboo production in Zhejiang Province 1a 3 to 4 generations, are over the winter with the pupa in the soil surface. The incidence of adult worms are from early April to early May, early June to early July, late July to late August, late September to mid-October respectively. The larvae harms were from late April to mid-June, mid-June to early August, mid-August to early October, and the third generation of pupal wintering larvae could be extended to the end of October, the fourth generation of mid-October, Late November. The 3rd instar larvae fed on the leaves at different instars were 1.57, 7.73, 16.36, 57.0 and 2,579.78 cm 2, respectively. The larvae fed a total of 662.46 cm 2 of bamboo leaves. Female larvae eat more leaves than the male 12% to 15%, each adult fecundity of 161 to 2,86. Natural enemies Trichogramma, black eggs, wasps, fly and so on. And put forward the corresponding prevention and cure method
