黄蛱蝶是为害苎麻较普遍,且较严重的害虫。幼苗受害,影响早生快发,有效株减少4～7％;成株期受害,叶片受害率达24～56％。产量一般损失达8％左右,是苎麻高产优质的障碍因素之一。 五十年代末浙江农大对此虫的形态特性、生活史方面有过简单记载,六十年代我省农业厅相继进行过调查;八十年代宜春地区农科所曾进行过小面积防治试验,取得较好的效果。随着麻织品出口的扩大,种植苎麻面积发展很快,对产量与品质的要求愈来愈高。为确保苎麻高产优质,我们在以往小区试验基础上,1985年在分宜县麻区推广药剂适时防治黄蛱蝶取得了很好的效果。 Yellow butterfly is the damage to ramie more common, and more serious pests. Seedlings affected, affecting the early fast hair, effective strains reduced by 4 ~ 7%; adult damage, leaf damage rate of 24 to 56%. The general loss of output of about 8%, is ramie high yield one of the obstacles. The late 1950s Zhejiang Agricultural University morphological characteristics of this pest, life history has been a simple record, the province’s Department of Agriculture in the 1960s have conducted a survey; agricultural areas in the 1980s Yichun had conducted a small area of ​​prevention and control of the experiment, obtained Better effect. With the expansion of the export of hemp fabrics, the area for ramie planting has been developing rapidly, and the requirements on the output and quality have become higher and higher. In order to ensure the high yield and quality of ramie, on the basis of the previous plot test, in 1985, it was proved that Huangma butterfly can be used in the promotion of medicament timely and effectively in the area of ​​Fenyi County.
