茶木蠹蛾ZeuzeracoffeaeNietner是茶树的主要枝干害虫之一,尤其是新辟茶园被害严重。在安徽省一年1代,以老熟幼虫越冬,幼虫期为5龄,危害期长达120—150d,一生中可转移钻蛀5—10个枝干。经变温测定:蛹期发育起点温度C=(15.0±0.7)℃,有效积温K=(174±12)DD,预测式N=(174±12)/〔T-(15.0±0.7)〕(d),卵期发育起点温度C=(17.6±0.8)℃,有效积温K=(124±7)DD,预测式N=(124±7)/〔T-(17.6±0.8)〕(d)。
Tea looper moth ZeuzeracoffeaeNietner is one of the main stem pests of tea trees, especially the new tea plantations were severely victimized. In Anhui Province a generation a year to mature larvae overwinter, larvae of 5 years, the damage period of up to 120-150d, life-long transfer of 5-10 borers drill stem. The change of temperature at the beginning of pupal stage was C = (15.0 ± 0.7) ℃, and the effective accumulated temperature was K (174 ± 12) DD. The predictive value of N was (174 ± 12) / [T- ± 0.7)] (d), the onset temperature of egg stage was C = (17.6 ± 0.8) ℃, the effective accumulated temperature K was (124 ± 7) DD, the predictive value N was (124 ± 7) / [ T- (17.6 ± 0.8)] (d).
