苧麻卜馍夜蛾属鳞翅目、夜蛾科。迄今除中国麻作所张继成等人1987年曾报道外,尚无他人作过专门研究。该害虫的发生和危害不压于苧麻夜蛾,1983年起连续3年对该虫作了田间,室内药效试验和药剂筛选工作,现介绍如下: 一、发生和危害性在达县地区多年调查,以新栽麻区和新植苧麻地的植株,发生量人,危害较重。一年之内,头麻地少、二麻地多,有两个完整的世代,有时三麻比二麻发生量大,危害重。据1983—1985年期间在达县、大竹等地调查,重害麻田内的虫口密度至少在8万头以上,对苧麻产量的影响是很大的。卜馍夜娥的幼虫多集中在苧麻的叶背上危害,初孵幼虫将下表皮翻开,只啃食叶肉,留下
Ramie Bupawiensis genus Lepidoptera, noctua. So far, except for the case of Zhang Jicheng, who was under the supervision of China’s Ma Zuozuo, who was reported in 1987, no other people have done any special research. The occurrence and harm of the pest does not pressure ramie nightworm, since 1983 for three consecutive years the field made in the insects, indoor efficacy tests and pharmaceutical screening, are as follows: First, the occurrence and dangers in the Daxian area for many years Investigation to newly planted areas and newly planted ramie plants, the amount of people, endanger the heavier. Within a year, there are fewer head and thickened land, more land and more land, and two complete generations. Sometimes three mulch produce more than two mulch and endanger heavy weight. According to the survey conducted in Daxian and Dachang from 1983 to 1985, the density of pest population in Matiantia was at least 80,000 or more, which had a great impact on the yield of ramie. Bu 馍 nocturnal E larvae are mostly concentrated in the leaves of ramie on the endangered, newly hatched larvae open the lower epidermis, eating only the leaves, leaving
