| 摘 要： | 松叶蜂在贵州省主要分布在凤冈、清镇、平坝、安顺、普定等县，松叶蜂以幼虫为害松树林木的针叶，影响林木生长，重度为害时，可造成林木零星或成片枯死。2007年下半年，松叶蜂（第2代）在凤冈县大面积发生，使凤冈县400hm^2的松林遭到危害。在凤冈县进行了松叶蜂生活史调查和防治试验。试验结果表明，松叶蜂在凤冈县一年发生两代。第一代发生在4月上旬至7月上旬，第2代在7月上旬至翌年的4月上旬。第一代幼虫发生在5月中旬至6月中旬，第2代幼虫发生在8月中旬至9月中旬。对松叶蜂的防治可在两个时期进行，即茧期和幼虫期，可分别采取物理防治和化学防治，化学防治比物理防治更有效、彻底。化学防治的最佳时期为5月中旬和8月中旬，喷药防治的效果显著高于烟雾防治，可将灭幼脲和速灭杀丁作为首选药物。

| Abstract: | Pine sawfly was mainly distributed in Fenggang,Qingzhen,Pingba,Anshun and Puding of Guizhou Province.Pine sawfly was pine tree needle pest and influenced forest growth.Severe pine sawfly caused few or many withering forest.At the second half year of 2007,pine sawfly(second generation) occurred in large areas of Fenggang County,which damaged 400 hm2 pine forest in Fenggang County.Investigation and control measures of the life history of pine sawfly were carried out in Fenggang County.Test result showed that there were two generations of pine sawfly in Fenggang County within each year.The first generation was from early April to early July,and the second generation was from early July to early April next year.The larvae of first generation was from middle May to middle June,and the larvae of second generation was from middle August to middle September.The control of pine sawfly could be carried out at two stages(cocoon stage and larvae stage) by physical control and chemical control.And the chemical control was more effective and complete.The optimum stage for chemical control was middle May to middle August.Efficiency of spraying control was higher than that of smog control,and the diflubenzuron and sumicidin were the preferred pesticides. |
