摘要: 鞭角华扁叶蜂在浙江省温州市主要危害柳杉, 1 a 发生1 代, 以老熟幼虫在2 ~ 20 cm土层中筑土空越冬越夏。越冬滞育幼虫次年4 月中旬开始化蛹, 5 月上旬开始产卵, 5 月下旬幼虫孵化并开始危害, 6 月中旬为危害盛期。林间防治试验表明, 40 %氧化乐果1 000 倍液, 施药量30 kghm-2 , 4 龄前幼虫死亡率为97.5 %, 5 ~ 6 龄死亡率为91.3 %;2.5 %溴氰菊酯800 倍液, 施药量225 mLhm-2 , 4 龄前幼虫死亡率为97.8 %, 5 ~ 6 龄死亡率为93.6 %。表4 参3

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 .
