Abstract: | Incorporation of [14C]leucine into proteins of 3rd instar Culex pipiens quinquefasciatus Say larvae increases linearly with time between 1 and 4 h. Garlic oil as well as the active larvacidal principle from it, viz. diallyl disulphide, inhibits significantly synthesis of the larval proteins. The maximum reduction in incorporation is observed during the first hour of treatment. The incorporation of [14C]phenylalanine is also inhibited by garlic oil and the effect is irreversible. Garlic oil does not seem to have any effect on proteins already labelled and it does not suppress substantially oxygen uptake by the larvae. |
