柑枯潜叶蛾是柑桔主要害虫之一,为害新梢嫩叶,容易引起溃疡病发生。1980-1987年初,我省推广使用了拟除虫菊酯类农药,有效地控制了柑桔潜叶蛾的为害,保障了柑桔正常的生产。但是,1987年夏、秋梢期,各地先后发现拟除虫菊酯类农药防治柑桔潜叶蛾药效明显下降,甚至无效。对此我们经过两年研究,认为沙蚕毒类农药、苯酰脲类农药和有机磷农药水胺硫磷等,可取代拟除虫菊酯类农药防治柑桔潜叶蛾,获得较理想的防治效果。现将研究结果述后。材料和方法 1.供试药剂:10％高效灭百可乳油(英国壳牌公司产)、20％速灭杀丁乳油(日本住友化学工业公司产)、20杀灭菊酯乳油(石岐农药厂产)、巴丹原粉(含量98.6％,日本武田药
Citrus moth leaf moth is one of the major pests of citrus, damage shoots young leaves, easily lead to ulcer disease. From 1980 to 1987, the province promoted the use of pyrethroid pesticides, which effectively controlled the damage of citrus leafminer and ensured the normal production of citrus. However, the summer of 1987, the autumn period, around the pyrethroid pesticides have been found around the efficacy of citrus leaf moth significantly decreased, or even invalid. In this regard, after two years of research, we believe that Nereis also have the potential to be more effective in preventing and treating citrus leafminer insects by replacing pyrethrins with pesticides such as chlorfenapyr, . The research results are described later. MATERIALS AND METHODS 1.
