The study, firstly, aimed to study an efficiency and a long-lasting effect of Lambda-cyhalothrin10%CS impregnated netting–jacket (30 mg/m2) against Anopheles minimus (laboratory strain), and Aedes aegypti (laboratory and Rayong strains). Secondly, the study attempted to test an effect of Lambda-cyhalothrin10%CS impregnated-netting cloths, and insecticide susceptibility level on Aedes aegypti (Rayong strain) by following the WHO standard procedure. The results found that the efficiency of Lambda-cyhalothrin10% CS impregnated netting–jacket (30 mg/m2) on An. minimus achieved greater than 80% mortality rate over seven months period and its efficiency of impregnated-netting cloths (at 30, 60, and 120 mg/m2) was last longer than six months against Ae. aegypti (laboratory strain) but it was not effective against Ae. aegypti (Rayong strain) in any dosages. Moreover, Ae. aegypti (Rayong strain) was also resistant to Lambda-cyhalothrin at standard diagnostic doses of 0.03% and 0.15% with 8.13 and 44.33 mortality rates, respectively. It was concluded that Lambda-cyhalothrin10%CS impregnated materials were likely effective to control An. minimus better than Ae. aegypti. However, before a large-scale implementation, the adverse effects and acceptance on the target population should be studied.
