Abstract

Mosquitoes serve as one of the main vectors in the transmission of zoonotic diseases including malaria, dengue and lymphatic filariasis from one host to another host. This present study was done to determine the prevalence of mosquito-borne endoparasites in several endemic residential areas for filariasis in Kuching, Serian and Betong Division, Sarawak. Mosquitoes were collected by mosquito net and human landing method. Thick blood smears were stained with Giemsa to examine for the presence of mosquito-borne endoparasites. There was a total of 47 individuals (34.49%), 28 individuals (74.40%), eight individuals (4.85%) and 14 individuals (3.64%) of bloodfed mosquitoes sampled in first and second samplings at Kampung Serian Ulu, Kampung Krusen Kranji and Kampung Rampangi respectively. Low occurrence of mosquito-borne endoparasites (n=2; 0.35%) from one female Culex and one female Aedes found in first sampling at Kampung Serian Ulu and (n=l, 0.43%) from one female Culex in the second sampling at Kampung Serian Ulu was detected positively for microfilarial nematode but negative in other two sampling sites. The occurence of female and blood-fed mosquitoes was highly dependent on the density of human and backyard farming at the study sites. There was low occurrence of vectors for filariasis in all study sites.
