The testing of efficiency of chemical insecticide in single and multiple formulation to death of Andes mosquitoes which carrier to Dengue fever with fogging machine in healthy region 3

Abstract

The objective of study is the effectiveness of chemical in single and multiple formulation to fogging to killed insect which carrier to Dengue fever with fogging machine as guideline of department of disease control and studied the rapidly and trendly of resistant of Andes mosquitoes in healthy region#3 by Cage Bio-assay as the standard of world health organization. (WHO) For using of substance of insecticide from regional surveying: Single formulation has 2 types, it is consisting of Deltamethrin 1% W/V EC and Cypermethrin 10% W/V EC. Multiple formulation have 2 types, Deltamethrin 0.5% W/V plus S-Bioallethrin 0.75% W/V and Casper-Series (Zeta-cypermethrin 2.25% W/V. The ratio of substance of insecticide will refer as the guideline of maximum value of WHO by testing with Aedes Aegypti amount 6 types as following: Aedes mosquitoes in laboratory (F61) and Andes mosquitoes in region of Kosamphee Kamphaengphet, Sanburi Chainat, Chumtabong Nakhonsawan, Buenarang Pichit and Huaikhot Uthaitani. The result of study of effectiveness of single and multiple formulation can affect to death of Aedes mosquitoes in laboratory more than 90% which it is not different with multiple formulation to testing with region. It was found that the effect with region of Buenarang Pichit 75.2%, Kosamphee Kamphaengphet 80% which less than standard of WHO. So, all of single-1 single-2 and multiple-1 formulation are effect to kill Andes mosquitoes more than 90% in 6 types. Andes mosquitoes in region, Buenarang Pichit and Kosamphee Kampaengphet have decrease of sensitivity with multiple-2 formulation.  The fogging of insecticide will have effectiveness as the guideline of department of disease control.
