摘要
桃小食心虫是我国北方枣树常发性蛀果害虫,也是宁夏中宁圆枣种植区的主要害虫。通过持续监测与调查,掌握桃小食心虫在中宁圆枣上的发生规律和为害特点,并通过定期调查诱蛾量和蛀果率,比较微胶囊迷向剂、迷向丝对桃小食心虫的防治效果。结果表明:桃小食心虫在中宁枣区1年发生1代,以老熟幼虫在树冠下1 m半径范围内的表土或储藏附近的土中做茧越冬,成虫出土盛期一般在5月下旬至6月中旬。透明胶管和膏体迷向剂区树冠上部蛀果率均为1.5%。研究桃小食心虫性信息素迷向防控技术在宁夏中宁圆枣产区的应用效果,可为该害虫的绿色防控提供参考。
The Carposina niponensis Walsingham fruit-boring insect pest and frequently occurs in jujubes in northern China.It is also the primary pest in the round jujube planting region in Zhongning of Ningxia.The sex pheromones has been used to prevent and control the pests,which could provide references for green prevention and control.Its occurrence laws and damage characteristics have been obtained through continuous monitoring and investigations.The control effects of microcapsules lure agent and lure filament were compared through regular surveys of trap catches and the rate of bored fruits.The results show that it has one generation per year in jujube planting area of Zhongning.The mature larvae overwinter in the surface soil within 1 m radius under the crown,or in the cocoons of nearby soil.The adults become active generally in late May and middle of June.The rates of fruit decay are all 1.5%in the upper part of the crown under the treatment of transparent hose and pasty lure agents.
