Susceptibility studies on Culex tritaeniorhynchus Giles, 1901, to insecticides in the state of Goa.
Tests conducted on the adults of C. tritaeniorhynchus in Goa during 1988-89 against organochlorine, organophosphate and carbamate insecticides showed that the LC50 values against DDT and dieldrin after 1 h of exposure were 2.2 and 1.2 per cent respectively. The LT50 values against malathion (5%), fenitrothion (1%) and propoxur (0.1%) were 19, 22 and 35 min respectively. Thus, taking into consideration the base-line data available for C. quinquefasciatus, the species can be considered susceptible to dieldrin, malathion, fenitrothion and propoxur. However, the results with DDT were equivocal and require verification.
