title: Host-feeding pattern of Culex quinquefasciatus Say and Mansonia annulifera (Theobald) (Diptera: Culicidae), the major vectors of filariasis in a rural area of south India.
abstract: Culex quinquefasciatus and Mansonia annulifera are abundant in the rural areas of Kuttanadu, Kerala, India. Bloodmeal identification for individuals of these species collected in this region was determined by the agar-gel precipitin test. A total of 2,328 blood smears from Cx. quinquefasciatus (1,148) and Ma. annulifera (1,180) was tested. Results showed that Cx. quinquefasciatus and Ma. annulifera were highly anthropophilic and that human feeding accounted for 74 and 66% of the total bloodmeals tested. Feeding on cattle accounted for only 1.5 and 2.1% of Cx. quinquefasciatus and Ma. annulifera bloodmeals, respectively. This study showed the high anthropophilic feeding rates of Cx. quinquefasciatus and Ma. annulifera collected from an endemic belt of Malayan filariasis, where epidemiological studies revealed the coexistence of Bancroftian and Malayan filariasis.
