摘　　要：用45%晶体石硫合剂、40%杀扑磷乳油、24%虱蚧净乳油、2.5%敌杀死乳油、40%氧化乐果乳油5种农药,在花椒吹绵蚧休眠期和若虫活动游走期进行农药防治试验。结果表明,在花椒吹绵蚧休眠期用45%晶体石硫合剂防治的最佳时期为3月中旬;花椒吹绵蚧若虫活动游走期,农药防治最佳时期为4月中旬,防治效果依次为40%杀扑磷乳油>24%虱蚧净乳油>2.5%敌杀死乳油>40%氧化乐果乳油。In dormant and activities wander period of Icerya purchasi Maskell of Chinese prickly ash,pesticide control test was carried out using 45% lime sulphur crystal,40% methidathion oil,24% lice targioni oil,2.5% decisoil oil,40% omethoate oil.The results showed that mid-March is the best time of pesticide control in dormant period of Icerya purchase Maskell of Chinese prickly ash,and mid-April is the best time for pesticide control in activities wander period of Icerya purchasi Maskell of Chinese prickly ash.The pesticide control effects in proper order is 40% methidathion oil 24% lice targioni oil2.5% decisoil oil40% omethoate oil.
