采用悬挂防虫帐、色板和糖醋液诱杀防治杨梅果蝇,比较不同方法的杨梅果蝇成虫或幼虫数量,筛选杨梅果蝇较佳的绿色防控技术。结果表明,3种方法对杨梅果蝇均有较好的防治效果,其中防虫帐法可极大地减少果实中果蝇幼虫数,比对照(色板:1块黑板+1块黄板)鲜果和落果的果蝇幼虫数分别低18.5头/百果和13.7头/百果。比较不同色板(黄色和黑色)和不同颜色糖醋液容器(黑色、透明和红色),发现杨梅果蝇对黑色有明显趋性。黑色容器+敌百虫∶红糖∶白醋∶白酒∶清水=1∶5∶10∶10∶20处理的诱杀效果较好。建议以防虫帐或黑板+糖醋液诱杀对杨梅果蝇进行绿色防控,以减少化学农药施用。
The use of insect pest control, color plates and sweet and sour vinegar trapping prevention and control bayberry fruit fly, compare the different methods of the number of adults or larvae of fruit fly, screening bayberry fruit flies better green prevention and control technology. The results showed that all the three methods had good control effects on the fruit flies of Myrica rubra. The insect-repellent method could greatly reduce the number of fruit fly larvae in the fruit, and the number of fruit flies was significantly lower than that of the control (color board: 1 blackboard + 1 yellow board) The number of fruit fly larvae dropped 18.5 heads per hundred and 13.7 heads per hundred fruit, respectively. Comparison of different color plates (yellow and black) and different colors of sweet and sour liquid containers (black, transparent and red), found that bayberry fruit flies on black obvious predisposition. Black container + trichlorfon: brown sugar: white vinegar: white wine: water = 1: 5:10:10:20 trapping treatment effect is better. Proposed insect pest control or blackboard + sweet and sour vinegar on the green fly control of fruit fly to reduce the use of chemical pesticides.
