摘要
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）。
Zeuzera coffeae Nietner is one of the dominant insect pests which damages branches and stems of tea plants,especially of young tea plants.In Anhui Province,the pest has one generation per year and overwinters in the 5th instar of adult larvae.The damaging period lasts 120—150 days and the larva damages 5—10 branches or stems all its life.According to the varying temperature measurements,the initial development temperature is (15 0±0 7)℃ for the pupa,(17 6±0 8)℃ for the egg,the effective accumulated temperature is (174±12) DD for the pupa,(124±7) DD for the egg.The predicting formulas are as follows:N=(174±12)/ T-(15 0±0 7) (d) (pupa);N=(124±7)/ T-(17 6±0 8) (d) (Egg).
