EFFECTS OF DIFFERENT GROWTH FACTORS ON THE POTATO APHID, MACROSIPHUM EUPHORBIAE (APHIDIDAE: HOMOPTERA), FED ON AN ARTIFICIAL DIET1
Published online by Cambridge University Press: 31 May 2012
Abstract
Macrosiphum euphorbiae (Thomas) was fed on artificial diets containing coumarin, phloridzin, kinetin, kinetin riboside, royal jelly, ALAR-85, and chlorogenic acid. Incorporation of chlorogenic acid in the artificial diet improved the growth of the potato aphid which was studied up to 17 generations. Coumarin and kinetin riboside at higher concentrations inhibited growth whereas phloridzin prolonged the developmental period of aphids in the second and third generations. The inhibitory effect of ALAR-85 and kinetin became apparent in the third and second generation nymphs, respectively, which did not reach the adult stage. Addition of royal jelly neither enhanced growth nor fecundity of M. euphorbiae.
