摘要
1995～ 1999年 ,在新疆库尔勒市对梦尼夜蛾生物学特性及其防治进行了调查研究。梦尼夜蛾 1年发生 1代 ,以蛹在土壤 2 0～ 10 0 mm深处越冬。3月上旬始见成虫 ,发蛾高峰在 3月底 4月初 ,产卵部位集中 ,孵化整齐。幼虫共 6龄 ,平均历期为 2 9.6天 ,以幼虫食叶危害 ,危害盛期为 4月中旬至 5月上旬。
The paper reported the results of an investigation on the bionomics and control of Orthosia incerta Hiifnagel in 1995～1999 in Kuerlecity,Xinjiang. The results showed that the insect has one generation a year and overwinters with pupae in soil at the depth 20～ 100mm. In the first ten days of March, the adult begins to emerge. The climax of emerging happens from the late March to the early April. The larval has six instars with 29.6 days of the average larva stage, and in mid-April to earlyMay causes severe damage on leaves. The general control method against the pest is also proposed.
