ABSTRACT The feeding capacity of C. carnea larvae on T.aurantii and C.hesperidum was investigated under laboratory conditions of 25°C ± 2 and 60-70 % R. H. It was found that the predating efficiency increased as the larvae grew older. Rate of prey consumption was highest on T.aurantii. The biomasses of carbohydrate, lipid and protein consumed by larvae were estimated. The results showed that a certain quantity of protein was consumed by the larva at each instar whatever the type of prey, while the quantity of the other two components depended on the prey type. |
