蔬菜生产上常见的潜叶蝇种类主要有四种:美洲斑潜蝇、南美斑潜蝇、番茄斑潜蝇、豌豆潜叶蝇。它们危害的共同特点都以幼虫潜入叶片内取食叶肉为主,但危害最重的则是豌豆潜叶蝇。一、危害症状识别1.美洲斑潜蝇:成虫、幼虫均可危害。成虫在叶片正面取食和产卵,幼虫从叶片正面潜入叶片和叶柄危害,产生不规则蛇形白色虫道,叶绿素被破坏,影响光合作用,受害重的叶片脱落,造成花芽、果实被灼伤,影响蔬菜产量,严重时使植株枯死。美洲斑潜蝇发生初期虫道呈不规则线状伸展,虫道终端明显变宽有别于 There are mainly four kinds of leaf miner commonly found in vegetable production: leaf miner, leaf miner, leaf miner and pea leaf miner. Common characteristics of their harm to larvae sneak into the leaves of the predominant leaves, but the most damaging is the pea leaf miner. First, the identification of hazardous symptoms 1 American Leafminer fly: adult, larvae can be hazardous. The adult larvae feed on the front of the leaves and lay eggs. The larvae infiltrate the leaves and petioles from the front of the leaves to produce irregular serpentine white larvae. The chlorophyll is destroyed and the photosynthesis is affected. The heavily damaged leaves fall off, resulting in flower buds, burns, Affect the yield of vegetables, the plants died in serious cases. In the early stage of occurrence, the American larvae showed irregular linear extension,
