柿树真绵蚧Eupulrinariacitricola(Kuwana)的报道在国内尚属首次。近年来该虫在河北省部分柿产区日趋严重,成为柿树的一种重要害虫。该虫在当地1年发生1次。以2龄若虫在当年生枝条上越冬,第二年3月上旬越冬虫体复苏,4月20~25日成虫交配,5月20~25日雌成虫产卵,6月10~20日若虫孵化后,固定在叶片上越夏,9月下旬越夏若虫蜕皮进入2龄,并转移到当年生枝条上越冬。农药防治结果表明:久效磷、氧乐果等有机内吸剂的防治效果很好,防治的最佳时间是6月中旬。该虫在当地的主要天敌有红点瓢虫ChilocoruskuwanaeSilvestri、黑缘红瓢虫C.rubidusHope和一种寄生蜂。
For the first time in China, the report of Eupulrinariacitricola (Kuwana) In recent years, the insects have become increasingly serious in some persimmon-producing areas in Hebei Province and become an important pest of persimmon trees. The bug occurs once a year in the area. The second instar nymphs were overwintered in the branches of the current year. The second trimester of early March recovered the overwintering larvae, adult mating on April 20-25, female adults oviposition on May 20-25, and nymph hatching on June 10-20 After fixed in the leaves of the summer, summer nymphs in late September molt into the 2nd age, and transferred to the annual branches of winter. Pesticide control results show that: monocrotophos, omethoate and other organic endosulfan control effect is very good, the best time to prevent and control in mid-June. The insects in the local main predators are red dot ladybugs ChilocoruskuwanaeSilvestri, black rim ladybug C.rubidusHope and a parasitic wasp.
