一、桃蛀螟的防治。桃蛀螟俗称桃蛀心虫,一年发生2～3代,以老熟幼虫在树皮缝、树洞、向日葵花盘和玉米秸秆内越冬。桃蛀螟成虫喜在枝叶密茂的桃果上产卵,或在两个及两个以上的桃果相互靠近的地方产卵,初孵幼虫先在果梗基部沿果核蛀入为害。幼虫蛀食果肉,排出虫粪为害后的果实不堪食用。防治措施:①冬季清园时,树干老翘皮刮除干净,集中烧毁,清除并烧毁桃园附近的玉米和向日葵等秸秆。②成虫发生期,在桃园中用黑光灯或挂糖醋液罐诱杀成虫。③害虫发生期及时摘除虫果,捡拾落果。④5月中旬对果实进行套袋。⑤在桃蛀螟卵期与幼虫孵化期喷布
First, beetle borer control. Peach moth borer, commonly known as peach wormworm, occurred 2 to 3 generations a year to mature larvae in bark stalks, tree holes, sunflowers and corn stalks wintering. Peach moth adults prefer to spawn on peach trees with dense foliage or spawn where two or more peaches reach each other. The newly hatched larvae are preyed at the base of the stem. Larvae eaten fruit pulp, excreted insect pests harmful to the fruit after eating. Prevention and treatment measures: ① in the winter clearing garden, the old tree bark scraping away the old scraps, concentrated burned, cleared and burned Taoyuan near the corn and sunflower straw. ② adults occur in Taoyuan, black light or hanging vinegar tank trapping adults. Pests timely removal of insect fruit, pick up and drop fruit. ④ mid-May fruit bagging. ⑤ in Taoyu borer eggs and larvae hatching period spray
