摘要
在金阳县800—1800 m不同海拔段,对棉蚜寄生蜂种类和数量进行了调查。寄生蜂对棉蚜寄生率为2.63%。共发现棉蚜寄生蜂3科3属4种:蚜虫跳小蜂Aphidencyrtus aphidivorus、印度三叉蚜茧蜂Trioxys indicus、蚜茧蜂T.sp.、棉蚜蚜小蜂Aphelinus gossypii。印度三叉蚜茧蜂占寄生蜂总数的90.38%,是花椒棉蚜寄生蜂优势种群。经统计,印度三叉蚜茧蜂在1000—1800m范围内随着海拔升高而雌雄性比下降。
The species composition and number of the parasitoids against Aphis gossypii in Zanthoxylum armatum were investigated at different altitudes of 800-1800 meters in Jin Yang county.The parasite rate of parasitoids was 2.63%.Four species of parasitic wasps belonging to 3 families,3 genera were found:Aphidencyrtus aphidivorus,Trioxys indicus,T.sp.,Aphelinus gossypii.Trioxys indicus account for 90.38%of the total number of parasitic wasps,and was the dominant population of Aphis gossypii.The other three species were Aphidencyrtus aphidivorus,T.sp.and Aphelinus gossypii.According to statistics,the ratio of Female-Male of Trioxys indicus decreased with the increase of altitude in the range of 1000-1800 meters.
