Biting behavior of Malaysian mosquitoes, Aedes albopictus Skuse, Armigeres kesseli Ramalingam, Culex quinquefasciatus Say, and Culex vishnui Theobald obtained from urban residential areas in Kuala Lumpur. Asian Biomedicine 8(3): 315-321
Background: There are several species of mosquitoes that readily attack people, and some are capable of transmitting microbial organisms that cause human diseases including dengue, malaria, and Japanese encephalitis. The mosquitoes of major concern in Malaysia belong to the genera Culex, Aedes, and Armigeres.
Objective: To study the host-seeking behavior of four Malaysian mosquitoes commonly found in urban residential areas in Kuala Lumpur.
Methods: The host-seeking behavior of Aedes albopictus, Armigeres kesseli, Culex quinquefasciatus, and Culex vishnui was conducted in four urban residential areas in Fletcher Road, Kampung Baru, Taman Melati, and University of Malaya student hostel. The mosquito biting frequency was determined by using a bare leg catch (BLC) technique throughout the day (24 hours). The study was triplicated for each site.
Results: Biting activity of Ae. albopictus in urban residential areas in Kuala Lumpur was detected throughout the day, but the biting peaked between 0600–0900 and 1500–2000, and had low biting activity from late night until the next morning (2000–0500) with biting rate ≤1 mosquito/man/hour. Biting behavior of Ar. kesseli was distinctly crepuscular, which exhibited two peaks of activity at 0600–0700 and 1900–2000, while Culex quinquefasciatus and Cx. vishnui were nocturnal feeders with multiple biting peaks throughout the night.
Conclusion: This study recommends optimal time for fogging to be conducted in Malaysia and neighboring countries according to the peak biting peak obtained.
