摘　　要：桦三节叶蜂是近年来湖北省神农架林区危害红桦树的主要食叶害虫。3%高渗苯氧威乳油、1.2%烟碱.苦参碱乳油、2%阿维菌素乳油、5%桉油精乳油喷雾、喷烟防治试验结果表明:3%高渗苯氧威乳油、1.2%烟碱.苦参碱乳油分别用水稀释25 000倍、6 000倍喷雾,48 h后,校正防效均达到89.5%;用柴油分别稀释120倍、50倍喷烟,48 h后,校正防效均达到93.6%。Arge sp. was an important defoliator attacking Betula albo-sinensis in Shennongjia Forest region. High permeation fenoxycarb 3% EC, matrine-nicotine 1.2% EC, abamectin 2% EC and eucalyptol 5 % EC were used against the pest by means of spraying or fogging. The results showed that the corrected control effect reached 89. 5 % 48 h after the spraying of high permeation fenoxycarb 3 % EC and matrine-nicotine 1.2% EC diluted into 25 000 and 6 000 times respectively with water while the corrected control effect reached 93.6% 48 h after the fogging of the above two pesticides diluted into 120 and 50 times respectively with diesel.
