摘　　要：[目的]筛选有效的加拿利海枣红棕象甲防治方法。[方法]采用灌淋法、灌根法和综合法3种化学防治方法,研究了生物农药0.3%印楝素对红棕象甲幼虫的防治效果。[结果]综合法防治效果最好,灌淋法其次,灌根法最差;采用综合法,喷施0.3%印楝素EC500和1 000倍液时,15 d后,防治效果分别为97.06%和89.66%。[结论]综合法喷施0.3%印楝素能有效防治加拿利海枣红棕象甲。[Objective] The study aimed to select the effective method to control the Rhynchophorus ferrugineus Larvae on Phoenix canariensis.[Method]The chemical control methods such as topical application,root irrigation and comprehensive method by spraying azadirachtin were carried out against the the Rhynchophorus ferrugineus Larvae on Phoenix canariensis.[Result] The Result showed that the control effect of comprehensive method was the best,topical application method was better,root irrigation method was worst.When 0.3% azadirachtin EC was diluted 500 times and 1 000 times applied to control the larvae,the control effect of was respectively 97.06% and 89.66% using comprehensive method by spraying 500 and 1 000 times liquid of azadirachtin after 15 days.[Conclusion] Using comprehensive method with spraying azadirachtin can be used to prevent the Rhynchophorus ferrugineus Larvae on Phoenix canariensis.
