Malaria is still one of the most important diseases in Malaysia. A study was conducted in the coastal area of Kuala Penyu, Sabah, where the malaria vector, Anopheles sundaicus s.s is highly abundant. This study aims to determine the biting patterns and the relationship between meteorological factors and the abundance of An. sundaicus s.s. Mosquitoes were collected indoors and outdoors by human landing collection from 1800 to 0600 h. All collected mosquitoes were identified to the species level. Meteorological parameters including monthly temperature, rainfall, relative humidity and wind speed were analyzed. A total of 2,294 An. sundaicus s.s were collected (2,010 outdoor and 284 indoor). Peak biting time for outdoor occurred between 2100 to 2200 h and between 2400 to 0100 h for indoor. The seasonal abundance of An. sundaicus s.s appeared to be influenced by monthly temperature patterns (p=0.0044), compared to other meteorological parameters. The population densities of An. sundaicus s.s showed the greatest abundance during high temperature season, April to August with the highest density was recorded in May, while December was the lowest. This study provides information on biting patterns throughout the night and seasonal abundance of An. sundaicus s.s. This information serves as a basis for providing health education on the importance of personal protective equipment among residents to prevent mosquito bites, as well as to improve vector control strategy planning to be more efficient, effective and reduce operating costs.
