栗瘿蜂 Dryocosmus kuriphilusYasumatsu 在我县栗林分布地区普遍发生,并有逐渐扩大的趋势,严重为害着栗林的正常生长和结实。为了大力发展板栗生产,促进山区经济建设,我们对栗瘿蜂及其天敌进行了研究。1980—1981年分别在我县玉川公社(海拔910米)、辋川公社(海拔720米)、红星公社(海拔1100米)及长安县的内苑公社(海拔520米),按照不同立地条件设立四个点,观察栗瘿蜂生活史和天敌资源。现将初步获得的资料整
Dryocosmus kuriphilusYasumatsu occurs in the distribution area of chestnut forest in our county, and has a tendency of gradually expanding, seriously damaging the normal growth and fruiting of chestnut forest. In order to vigorously develop the production of chestnuts and promote the economic construction in mountainous areas, we studied the chestnut bee and its natural enemies. From 1980 to 1981, they were set up according to different site conditions in Tamagawa commune (elevation 910m), Wangchuan commune (720m above sea level), Hongxing commune (1,100m above sea level) and Neiyuan commune (elevation 520m) Four points, observed chestnut bee life cycle and natural enemy resources. Now the preliminary information obtained
