弄蝶绒茧蜂Apanteles baoris Wilkinson,又名稻苞虫绒茧蜂,是直纹稻苞虫幼虫期寄生天敌的优势种.近年调查,稻苞虫各代自然寄生率一般为26.7-35.5%,最高达85.7%.稻苞虫幼虫被寄生后,食叶量减少28-63%,一般不结大苞,对抑制稻苞虫,减轻水稻被害程度作用明显.因此,1980年我们对此蜂的生物学特性作了进一步的观察,结果报道如下: Apanteles baoris Wilkinson, also known as the Brachypodium parasitoid, is the predominant species of parasitoids in the larvae of R. japonica .In recent years, the natural parasitism rate of the rice sheathworm was 26.7-35.5% Up to 85.7% .Basic insects larvae parasitic, the amount of leaves reduced by 28-63%, generally do not end bracts, inhibition of rice shellworm, reduce the degree of damage caused by rice significantly.Therefore, in 1980 we bees Biological characteristics were further observed, the results reported as follows:
