不同药剂对红棕象甲的防治效果研究

Study on Control Effects of Different Medicament on Rhynchophorus ferrugineus Fabricius

[目的]筛选防治红棕象甲的最佳药剂配方。[方法]设5组处理(其中1组为CK),3次重复,采用灌淋法,对为害国王椰的红棕象甲进行田间防治与室内防治研究,同时对未被红棕象甲危害的国王椰、大王椰、加那利海枣、老人葵进行药剂喷施,施药10 d后检查所用药剂对棕榈科植物的安全性。[结果]除CK外,其余4组药剂处理的防治效果均在65%以上。其中,以3%甲氨基阿维菌素苯甲酸盐500倍液的防治效果最佳,对红棕象甲幼虫的田间与室内的防治效果分别达93.35%、100%;其次为45%马拉硫磷500倍液,田间与室内的防治效果分别为84.45%、89.7%。同时,4种药剂对棕榈科植物安全。[结论]3%甲氨基阿维菌素苯甲酸盐500倍液对红棕象甲的防治效果最佳。

[Objective]The study aimed to choose the best medicament to control Rhynchophorus ferrugineus Fabricius.[Method]5 treatments were set up,3 repeats,the field control and indoor control were conducted by the method of trickling the medicament on the plants,at the same time,medicaments were sprayed on Ravenea rivularis,Roystonea regie,Phoenix canariensis,Washingtonia robusta H.Wendl,the security of each medicament to palmaceous plants were determined after 10 days.[Result]The control effects of 4 treatments reached above 65%.Among them,500 times liquid of 3%emamectin-benzoate had the best control effect,the effect of field control and indoor control were 93.35%,100%,respectively;secondly for 500 times liquid of 45%malathion,control effect were 84.45%,89.7%.And 4 medicaments were safe to palmaceous plants.[Conclusion]500 times liquid of 3%emamectin-benzoate had the best control effect.
