| 摘 要： | 豆野螟Maruea testulalisGeyer(1832)是我国豆类蔬菜,特别是长豇豆Vigna sesguipedalis的主要害虫。在杭州,一年发生七代,以预蛹越冬。以1—3代为害为主。一龄幼虫头宽0.197毫米,Dyar常数为1.653。随虫龄增加,取食场所从花器转向豆荚。产卵前期为3—4天,羽化后6—8天卵量最集中。幼虫、蛹发育历期与日平均温度间的对数回归方程为Y1=3.5825—1.7766x,Yp=3.8118-2.0800x。卵期2—4天。田间为害以6—8月为主;灯下威虫有7月和9—10月两个高峰。有分距姬蜂Cremastus sp.和稻苞虫寄蝇Pseudoperiehaeta insidiosa二种天敌。应用80%敌敌畏800倍等农药,在百花虫数达40头上下、二龄幼虫约占50%时,兼喷植株、落地花,能达到降低花、荚被害率,提高鲜荚产量、品质和降低成本的效果。

| Abstract: | The legume pod-borer, Maruca testulalis Geyer, is regarded as a key pest attacking vegetable legumes, especially the yard long bean, Vigna scsquipcdalis, in South China. Studies on its bionomics and control were conducted in Hangzhou during 1977-1980.By laboratory and field observation we found it had seven generations per year in Hangzhou. The first three generations were the most injurious. It overwintered as per-pupa near the soil surface and emerged in late May. The female moths fed with 25% glucose solution had preovipositional period of three to four days and the peak of ovi-position occurred on the sixth to eighth days after pairing. The young larvae attacked buds and flowers and the older larvae bore into the pods till pupation. Cremastus sp. and Pseudoperichaeta insidiosa were found to be larval parasites. Logarithmic regression equations of developmental time to mean atmospheric temperature of the days of larval and pupal development are Y,=3.5925-1.7766o; and Yp=3.8118-2.0800a; respectively. There are obviously two peaks of adult flight according to the light trap captures for seven years. Although the second peak is higher than the first one, the former is less important economically.Effective control may be effected by weekly application for two to three times with 80% DDVP (1:800) sparying at the moment when total amount of eggs plus larvae reaches about 40 per hundred flowers (half being the second instar larvae). |
