梨小食心虫性信息素诱捕器应用评价

梨小食心虫是梨树上一种重要的蛀食性害虫,为了推动果园害虫的无公害防治以及指导合理应用性信息素防治梨小食心虫,2012年在河北省昌黎县对梨小食心虫性信息素诱捕器进行了应用评价研究。研究了梨小食心虫的发生规律,性信息素诱捕器颜色、类型、放置位置等对梨小食心虫雄性成虫诱捕效果的影响。结果表明,梨小食心虫诱集出现3个高峰期,分别在6月下旬、7月下旬、8月中旬;三角式和船式诱捕器的诱捕效果显著优于水盆式和干式诱捕器;白色、绿色诱捕器效果明显好于黄色,树冠外围诱捕梨小食心虫的数量明显高于内膛。

Application Evaluation of Grapholitha molesta Sex Pheromone Traps

Grapholitha molesta Busck is an important pest in pear trees. In order to promote pollution prevention and control to guide the rational application of sex pheromone in oriental fruit moth control pear orchard application information in Changli county of Hebci province, the trap of Grapholitha molesta were applied in 2012. In the paper the infection regularity of Grapholitha molesta busck, sex pheromone traps color, type, position, effect of luring core number of Grapholitha molesta busck male adult trapping were studied. The resuhs showed the oriental fruit moth trapping appeared 3 peaks in late June, late July, and mid August respectively. Trapping effect of the triangle and the ship types was significantly better than the basin and dry type traps. White, green traps were significantly higher than that of yellow and the number of canopy entrapment Grapholitha molesta busck was also significantly higher than celia.
