Bionomics and control of Chinolyda flagellicornis

Abstract: Chinolyda f lagellicornis (F .Smith) is a main pest damaged Cryptomeria fortunei .It has one generation a year in Wencheng of Zhejiang and the naturation larvas hibernate in soil of 2 ~ 20 cm during winter and summer .The hibernating ungrowing larvas begin to be pupae in April of the next year , in the early May it begins to lay eggs , then the larvas begin to hatch and do harm, until in the middle of June the serious harming arrives . Control in forests could be made at the larval stage by spraying tree crowns with 1 000-fold solution (30 kghm-2) of omethoate 40EC , resulting in 97.5 %of the 1 ~ 4 instars larvae being killed , and 91.3 % of the 5 ~ 6 instars larvae being killed .With 800-fold sultion (225 mLhm-2) of deltamethrin 2.5EC , resulting in 97.8 % of the 1 ~ 4 instars larvae being killed , and 93.6 % of the 5 ~ 6 instars larvae being killed .
