萝卜蝇属双翅目花蝇科种蝇类,系腐食性害虫,对有机肥料发酵气味有强烈趋性。萝卜蝇的幼虫(俗称蛆虫),是由萝卜蝇成虫羽化后5——10天(一般为八月下旬左右)开始在萝卜、白菜等寄主植物的叶基部或株根周围0.5——3厘米潮湿的松软土壤中产卵,孵化24小时后蛀入寄主组织内生活。萝卜蝇的幼虫不仅危害萝卜表皮,造成许多弯曲的沟道,还能蛀入内部造成孔洞,并引起萝卜腐烂,失去食用价值。 防治方法 1.坡地或平地起垄种植。这样可使土壤排水良好,质地疏松,有机物分解 Drosophila diptera is a family of flies, which are rotten pests and have a strong tendency to ferment the organic fertilizer. Radish fly larvae (commonly known as maggots), is radish adult emergence from 5 to 10 days after emergence (usually about late August) in the radish, cabbage and other host plants around the leaf base or roots 0.5--3 cm wet Of spongy soil and hatch into the host tissue 24 hours after hatching. The larvae of the radish fly not only endanger the radish epidermis, causing many curved channels, but also erode holes and cause rotting and loss of food value. Control methods 1. Slope or flat Ridge planting. This will make the soil well drained, loose texture, decomposition of organic matter
