摘要
本文在掌握粟瘿蜂生物学、生态学特性的基础上,经广泛试验,在多种防治方法中,筛选出完全结合营林措施进行的"连年冬剪保护枯瘿"的治理方法。经实际应用,防效可达97.55%;挽回损失(平均)50.04%,产品品质提高。文中明确提出,在治理栗瘿蜂中,树势是基础,天敌是关键。
Extensive experiments have been done with a good command of the char- acteristics of ecology and biology about chestnut gall wasps.The way to control withered gall through continuous annual winter pruning has proved to be the best one combining with various measures in building forests. After the practi- cal application of it, the rate of controlling can come to 97.55%. The paper suggests that tree growth is essential and natural enemy is a decisive factor in the course of controlling chestnut gall wasps.
