Technical Abstract: A key strategy to reduce insect-borne disease is to reduce contact between disease vectors and hosts. In the current study, residual pesticide application and misting system were applied on militarily relevant materials and evaluated against medically important mosquitoes. Field evaluations were carried out in Chanthaburi province, Thailand from February to July 2015. Groups of ground-mounted structure of HESCO geotextile (2x3 m) and camouflage netting (3x3 m) were constructed. These materials are extensively used for perimeter defense during US military field operation. The residual pesticide formulation containing '-cyhalothrin and the pesticide misting system containing permethrin were applied on each type of structures. To evaluate effects of residual treatment and misting system, day and night biting mosquitoes were collected using BG sentinel traps and CDC light traps, respectively. Results demonstrated that treated HESCOs and camouflage netting enclosures substantially reduced mosquitoes (=50%) compared to untreated units. Moreover, misters significantly reduced mosquito populations at treated units more than treated structures without misters. The effect of residual pesticide on materials lasted for more than two weeks but could not be retained to week ten after application in this tropical climate. Residual pesticide applications and misting system on militarily relevant materials revealed the promising results for mosquito control in Thailand.
