栗瘿蜂(Dryocosmus kuriphilus Yasuma-tsu)属膜翅目瘿蜂科,是我国板栗的主要害虫。此虫在我县普遍发生,严重地为害着栗树的生长和结实。为了大力发展板栗生产,于1980-1983年我们对栗瘿蜂的生物学特性和防治进行了研究,现将四年来试验研究情况整理如下。一、为害情况栗瘿蜂主要为害栗树树冠中下部的发育枝和结果枝的第1-5腋芽,细弱枝受害后不能抽生新梢,枝条当年即枯死;中庸枝和结果枝受害后有的虽能抽生弯曲的枝条,长出细窄的小叶片和雄花序,但由于栗瘿生长,消耗营养
Dryocosmus kuriphilus Yasuma-tsu belongs to Hymenoptera and is the main pest of Chinese chestnut. This worm is common in our county, seriously harming the growth and robustness of chestnut trees. In order to vigorously develop the production of chestnut, we studied the biological characteristics and prevention and cure of the gallnut beetle in 1980-1983, and we now summarize the experimental research in the past four years. First, the damage situation Chestnut bee mainly chestnut tree chestnut branches in the lower part of the development and the results of the first branch of the axillary buds 1-5, after the weak branches can not be sprouted new shoots, twigs then died; moderate branch and the results after the branch has Although it can draw a curved branches, grow thin narrow leaflets and male inflorescences, but due to the growth of chestnut, consumption of nutrients
