Effect of malathion analogs upon resistant and susceptible Culex trasalis mosquitoes.
The effects of minor variations in the malathion molecule upon the resistance of Culex tarsalis have been examined. By replacing the carboethoxy group by carbomethoxy, the 60-fold resistance to malathion is abolished. The results confirm the importance of carboxyesterase action in determining susceptibility to malathion.
