Abstract:
Experiment on the predatory potential of grub and adult stage of C. sexmaculata on five different species of aphid, viz., mustard aphid, L. pseudobrassicae, cotton aphid, A. gossypii, maize aphid, R. maidis, cowpea aphid, A. craccivora and gaillardia aphid, U. compositae was conducted under laboratory condition at Department of Agricultural Entomology, B. A. College of Agriculture, Anand Agricultural University, Anand. The highest (21.67±1.31) number of A. craccivora individuals were consumed by first instar. Second instar preferred R. maidis (34.27±0.86), while third and fourth instar grubs were fed on A. gossypii, with consumption 57.13±1.02 and 79.87±0.77, respectively. Significantly, the highest (188.6±1.62) number of A. gossypii were consumed by grub than rest of aphid species. The maximum (828.2±7.96) numbers of A. craccivora was consumed by the adult of C. sexmaculata. Total consumption by C. sexmaculata in its entire life time was more on A. craccivora.
