摘要 测定内吸性药剂吡虫啉、乐果和敌敌畏对薄壳山核桃Carya illnoensis k.Koch警根瘤蚜Phylloxera notabilis的防治效果。试验结果表明,3种药剂施用后警根瘤蚜的数量均大幅减少,防效均在91%以上,以6%吡虫啉可湿性粉剂防效最好;施药4个月后,6%吡虫啉可湿性粉剂处理调控效应最好,株危害率和叶片危害率分别降低至3.3%和8.5%。生产上可选用6%吡虫啉可湿性粉剂进行防治。 The control effects of three pesticides imidacloprid,dimethoate and dichlorvos against Phylloxera notabilis on Carya illinoensis were determined. The results showed that the amount of P. notabilis decreased significantly after spraying with control effects all over 91%,a nd the best one was imidacloprid 6% WP. After 4 months of application, the imidacloprid 6% WP had the best control effect with plant damage rate and leaf damage rate decreased to 3. 3% and 8. 5%. Therefore, imidacloprid 6% WP was suggested to use in production.
