摘要： 板栗瘿蜂是我国板栗主要害虫,虫瘿是该害虫危害产物.在自然状态下,虫瘿的形成和发育性状在个体间差异显著.本文对栗瘿蜂在直观上容易识别和观测的虫瘿的形成及其形态、生物学指标进行检测,并对其与虫室数和虫量的相互关系进行定量分析,结果表明,单瘿质量近似正态分布,变异系数为0.1712,峰度系数1.3853,个体质量最大和最小相差15.5倍,体积相差6.4倍.虫瘿质量(X₁)、体积(X₂)与瘿内虫室数和虫数(Y)呈正相关关系,相关系数分别为R₁²=0.813,R₂²=0.874,达到显著水平.不同板栗品种对栗瘿蜂的抗性为处暑红>蜜蜂球>二水早.天敌主要是中华长尾小蜂,虫瘿寄生率72.7%,幼虫(虫室)寄生率24.06%.

Abstract: Dryocosmus kuriphilus is one of the most important pests on chestnut in China, and cecidum is the jeopardized result of Dryocosmus kuriphilus.Under natural condition, the growth status of different cecidum of Dryocosmus kuriphilus was differed, and the weight of individual cecidum was submitted to normal distribution. The zooecium number was positively related to cecidum quality and volume. For three different varieties of chestnut, their resistance to Dryocosmus kuriphilus were different, and the order was Chushuhong > Mifengqiu > Ershuizao. Torymus sinensis Kamijo was the dominant natural enemy. The cecidum-parasitized ratio was 72.7%, and the zooecium-parasitized ratio was 24.06%.
