    Abstract:
    Monthly indoor resting density, age distribution, survival rate and host-preference of Culex quinquefasciatus, a filariasis vector were studied from June 1988 to May 1989 in Mysore city. During this period, a total of 7522 adults were collected in 72 man-hour of search spreading to twelve spots covering the entire city. The annual per man-hour density observed was 104.5, being 76.8 for female and 24.3 for male. Nulliparous and parous (1-parous and 2-parous) mosquitoes were collected throughout the year while 3-parous and 4-parous mosquitoes were recorded during cold and rainy seasons only showing an increase in the number of gonotrophic cycles. Precipitin test of blood smears from the gut content of C. quinquefasciatus was done by taking 2536 mosquito blood smears. Of these, 94.1 per cent preferred human blood, 1.4 per cent bovine and 3 per cent avain. As the species evaluated is a major vector of filariasis, the present study on its resting density and the host preference will be helpful in vector monitoring in Mysore city. Various results on this species at Mysore have been discussed in the light of earlier studies conducted elsewhere.
