A comparison of different types of ovitraps for outdoor monitoring of aedes mosquitoes in Kuala Lumpur

Dengue is a significant public health problem in Malaysia and vector surveillance is one of the important components in a vector control program. Routinely vector surveillance in Malaysia is performed through larval surveys. However, larval surveys have several limitations. Thus ovitraps are used as an alternative method for monitoring dengue vectors. The aim of this study was to determine the effectiveness of Standard Ovitrap (SO), Mosquito larvae Trapping Device (MLTD), Double Sticky Ovitrap (DST) and NPK Fertiliser Trap to monitor the abundance of Aedes mosquitoes. Each ovitrap was placed at four different sampling points and rotated to the next position every one week. Larvae and adult mosquitoes were collected and identified in the laboratory. All four trapping methods successfully collected larvae of Aedes mosquitoes. The mean number of larvae per ovitrap in DST was significantly higher (p 0.05) between these solutions. Findings from this study conclude that DST is the most effective ovitrap to monitor Aedes larvae, while NPK Fertiliser trap is the most effective ovitrap to trap Aedes adult mosquitoes in the study area.
