| 摘 要： | 使用40%氧化乐果乳油、50%甲胺磷乳油两种内吸性杀虫剂树干注射防治松纵坑切梢小蠹的试验表明：树干注射化学药剂对防治蛀梢期小蠹成虫有较好的效果。两种药剂平均杀虫效率均在70%以上，50%甲胺磷的效果略高于40%氧化乐果。药剂对云南松树梢和针叶均无不良影响。以8月采取每孔注射1.5ml的40%氧化乐果乳油或50%甲胺磷乳油的防治效果最佳，杀虫率均达到87%以上。

| Abstract: | Experiment on control Tomicus piniperda by injecting 40% omethoate em ulsifiable concentrate (EC) and 50% methamidophos EC into stem shows stem inject ion has good effects on control of Tomicus piniperda adults in the period of eat ing tops of trees The average efficiency of the two chemicals reaches above 70 % , of which 50% methamidophos EC is a little higher than 40% omethoate EC The c h emicals have no side effect to the growth of the trees The optimum injection t i me is August and the proper amount is 15ml per hole, of which the efficiency w ill reach over 87% |
