地蛆是我市蔬菜的主要害虫之一,而韭菜受害最重。在掌握其消长规律的基础上采用糖醋液诱杀地蛆成虫,可避免农药喷撒及药液灌根方法的防效低、成本高、易污染环境的缺点。1.掌握关键防治期危害韭菜的地蛆种类繁多,世代交替复杂。但在我市每年大致有三个高峰期即下/4～上/5,下/5～上/6、中/9～上/10.在一般年份第一个高峰期最为明显。这三个高峰期即为防治关键时期,通过测报抓住第一高峰期到来之前大量诱杀成虫,并兼顾对其它各代的防治即可取得良好防效。
Maggot is one of the city’s major pests of vegetables, and chives hardest hit. On the basis of grasping the pattern of its growth and decline, the use of sweet and sour sauce to kill maggots adults can avoid pesticide spraying and liquid medicine irrigation method of low efficiency, high cost, easy to pollute the environment shortcomings. 1. Grasp the key prevention and treatment of leeks maggots a wide range of generations alternately complex. However, there are roughly three peak periods in the city each year, namely, the next / 4 ~ on / 5, the next / 5 ~ on / 6, medium / 9 ~ on / 10. The first peak in the general year most obvious. These three peak periods are the key period for prevention and control. By seizing the first peak period, a large number of trapping and killing of adult worms can be achieved by taking advantage of the control of other generations to achieve good prevention and control.
