不同剂型的氟虫腈制剂对蝇与蜚蠊的杀灭效果及使用剂量研究

Efficacy and dosage of the different fipronil formulations against fly and cockroach

目的研究不同剂型的氟虫腈制剂对蝇与蜚蠊的杀灭效果及使用剂量。方法采用国标GB/T 13917.7-2009《农药登记用卫生杀虫剂室内药效试验及评价第7部分:饵剂》、GB/T 13917.10-2009《农药登记用卫生杀虫剂室内药效试验及评价第10部分:模拟现场》、GB/T 13917.1-2009《农药登记用卫生杀虫剂室内药效试验及评价第1部分:喷射剂》分别对不同剂型的氟虫腈制剂的杀灭效果进行检测并评价,并运用方差分析与t检验对不同浓度、不同成分杀虫剂的杀灭效果进行比较。结果 3种不同厂家的2.5%氟虫腈悬浮剂对蜚蠊的药效达到国家A级标准;6种氟虫腈微乳剂对蝇的药效,除1家为不合格产品外,其他均分别达到国家A或B级标准,3%与6%氟虫腈微乳剂浓度组灭蝇效果差异无统计学意义(P>0.05);0.05%氟虫腈灭蟑胶饵达到国家A级标准,与其他成分的灭蟑饵剂的杀灭效果差异亦无统计学意义(P>0.05)。结论氟虫腈杀虫剂灭蝇与蜚蠊效果良好,但在具体使用中,需降低使用浓度。

Objective To determine the efficacy and dosage of the different fipronil formulations against fly and cockroach. Methods GB/T 13917.1-2009 Laboratory efficacy test methods and criterions of public health insecticide for pesticide registration- Part 1： Spray fluid; GB/T 13917.7-2009 Laboratory efficacy test methods and criterions of public health insecticide for pesticide registration-Part 7： Bait and GB/T 13917.10-2009 Laboratory efficacy test methods and criterions of public health insecticide for pesticide registration-Part 10： Analogous site are adopted to test and evaluate the efficacy of the fipronil formulations. One-way ANOVA and Independent-Samples t test are adopted for the comparison of the efficacy of the different groups. Results Three kinds of 2.5% fipronil flowable concentrates from different factories belong to rank A according to the national standard. Among the six different fipronil micro-emulsions, five of them belong to the rank A and B. There is no significant difference between 3% and 6% fipronil micro-emulsions on the efficacy against fly （P〉0.05）. The 0.05% cockroach bait belong to the rank A, which has no significant difference with other baits （P〉0.05）. Conclusion Different fipronil formulations have high efficacy against fly and cockroach, but should be used in lower dose.
