    • Behavioural responses of deltamethrin- and permethrin-resistant strains of aedes aegypti when exposed to permethrin in an excito-repellency test system. 

      Paeporn, P; Supaphathom, K; Sathantriphop, S; Chareonviritaphap, T; Yaicharoen, R (‎2007)‎
      his study compared the behavioural avoidance responses of the permethrin-resistant and deltamethrinresistant strains of Aedes aegypti, a primary vector of dengue haemorrhagic fever (‎DHF)‎ in Thailand. The background of biochemical-based resistance mechanism assay of these two strains revealed a significant increase of esterase activity and monooxygenase levels when compared with a laboratory- usceptible strain. Glutathione-S-transferase activity was found to increase only in the permethrin-resistant strain. The DNA sequence of knockdown resistance ...
    • Detection of insecticide resistance in Aedes aegypti to organophosphate and synthetic pyrethroid compounds in the north-east of Thailand. 

      Pimsamarn, S.; Sornpeng, W.; Akksilp, S.; Paeporn, P; Limpawitthayakul, M (‎2009-12)‎
      Aedes aegypti is a vector of dengue fever, which is a public health problem in the north-east of Thailand. During epidemics, emphasis is laid on the use of insecticides for the control of the disease. A survey of insecticides used was carried out in eight provinces, namely Amnat Charoen, Kalasin, Mukdahan, Nakhon Phanom, Sakon Nakhon, Si Sa Ket, Ubon Ratchathani and Yasothon. The study indicated that temephos was the only chemical used for the control of mosquito larvae while cypermethrin was used as space spray for the control of adult mosquitoes. ...
