Abstract
A year round study was conducted in Trivandrum city during the period of March 1984 to February 1985 to elucidate the relation between certain physico-chemical factors and seasonal density ofMansonia larvae (Culicidae: Diptera).Mansonia uniformis was found to be the predominant species during this period, whereasMansonia annulifera was less than 10% of the totalMansonia collected. The period of high prevalence was found to be January–March. Out of the 6 physico-chemical factors studied Na+, K+, and pH showed statistically significant correlation with the larval density, while Ca++, Mg++ and rainfall showed no significant relation.
