摘　　要：2004年对扬州地区露地蔬菜上的豌豆彩潜蝇寄主种类及危害程度进行了调查,采用五点取样法共查到豌豆彩潜蝇的蔬菜寄主6科23种,主要分布在菊科、十字花科、豆科和葫芦科等的蔬菜上,其中以莴苣、花椰菜、豌豆、油菜、蚕豆受害最为严重;选择性田间调查和室内试验证明,莴苣是豌豆彩潜蝇最嗜好寄主。根据不同蔬菜上的豌豆彩潜蝇发生危害动态分析了豌豆彩潜蝇在自然条件下对寄主的选择性。The host plant species and the harm extent of Chromatomyia horticola （Goureau） on outdoor vegetables were investigated in 2004 in Yangzhou City. There are 23 species of plants that belong to 6 families as hosts of C. horticola, in which Compositae, Cruciferae, Laguminosae and Cucurbitaceae are the main families. It occurs seriously on lettuce, cauliflower, pea, rape and horsebean. The hosts can be divided into four types： the most fitting host, fitting host, preferable host and secondary host. The oviposition of C. horticola on 8 kinds of hosts selected was checked under microscope, which had proved the investigation of host suitability and lettuce is the favorite host. According to the population dynamics of C. horticola on the outdoor vegetables, the host selectivity of C. horticola was analyzed under natural condition in this paper.
