摘　　要：目的 进一步明确薄荷油、尤加利油、木姜子油、广藿香油、柠檬油对除虫菊素气雾剂的增效活性,为其开发提供理论依据。方法 以淡色库蚊为试验昆虫,采用密闭圆筒熏蒸法测定5种精油对淡色库蚊的熏蒸时效;采用5.8 m^(3)小屋法对增效活性明显的植物精油进行复配组合,筛选出最佳复配组合配制成品气雾剂,并与市售产品进行室内药效及模拟现场测试比较。结果 在密闭圆筒熏蒸法中发现木姜子油、柠檬油、薄荷油、尤加利油、广藿香油对淡色库蚊均具有较好的生物活性,KT_(50)均在25 min以内。使用5.8 m^(3)小屋法试验得出增效效果较好的配方:P-A(10.0%木姜子油+1.0%除虫菊素),P-B(10.0%尤加利油+1.0%除虫菊素),P-G(6.0%尤加利油+10.0%木姜子油+1.0%除虫菊素),其增效系数分别为1.175 4、1.211 2、1.364 6。选取配方P-G制成气雾剂,采用5.8 m^(3)小屋法进行室内药效测试,采用28 m^(3)模拟现场法进行模拟现场测试。在室内药效测定中,配方P-G的KT_(50)为2.775 2 min, 24 h死亡率为98.67%;在模拟现场试验中,气雾剂P-G的KT_(50)为11.680 0 min, 24 h死亡率为73%。结论 除虫菊素气雾剂增效剂配方P-G具有明显的增效效果,产业化开发前景较好。Objective This study aims to provide further clarification regarding the activity enhancement effects of peppermint oil,eucalyptus oil,Litsea cubeba oil,patchouli oil,and lemon oil on pyrethrin aerosol insecticide,and to establish a theoretical basis for the development of this insecticide.Methods The common mosquito Culex pipiens pallens was employed as the test insect.The fumigant effect of five essential oils on Cx.pipiens pallens was determined by the closed cylindrical fumigation method.Based on the 5.8 m^(3) room method,the oils exhibiting discernible activity enhancement were combined by multiple combinations.In addition,the optimal combination was selected and formulated into a finished aerosol insecticide.This was then subjected to a comparison of indoor efficacy and a simulated field test of commercially available products.Results The closed cylindrical fumigation method demonstrated the efficacy of various essential oils,including Litsea cubeba oil,lemon oil,peppermint oil,eucalyptus oil,and patchouli oil,against Cx.pipiens pallens.The KT 50 values for these oils were all within 25 min,indicating their potential for rapid biological activity.The combinations that exhibited superior enhancement effects when utilizing the 5.8 m^(3) room method were as follows:The following combinations were identified as having the most promising enhancement effects:P-A(10.0%Litsea cubeba oil+1.0%pyrethrin),P-B(10.0%eucalyptus oil+1.0%pyrethrin),P-G(6.0%eucalyptus oil+10%Litsea cubeba oil+1.0%pyrethrin);and P-G exhibited the highest enhancement coefficient(1.3646),followed by P-B(1.2112)and P-A(1.1754).The P-G formula was selected for the production of the aerosol,and the 5.8 m^(3) cabin method was used for the indoor efficacy test.The simulated field test was carried out using the 28 m^(3) simulated field method.In determining the indoor efficacy of the formulation,P-G,the KT 50 was found to be 2.7752 min,with a 24-hour mortality rate of 98.67%.In the simulated field trials,the KT 50 of the aerosol formulation,P-G,was d
