Studies on the intraguild egg predation of Coccinella transversalis and Menochilus sexmaculatus were undertaken in the Bio-control Laboratory, Department of Entomology, IGKV, Raipur, Chhattisgarh during the year 2019-20 and 2020-21. Egg predation of M. sexmaculatus by different growth stages of C. transversalis was found to be significant. Among all the stages of C. transversalis, female beetle was found to be highly voracious towards the heterospecific egg predation. Maximum egg predation,i.e. 22.66 of M. sexmaculatus was observed by the female beetle of C. transversalis which was on par with the 4th instar larvae (19.10) followed by 3rd instar larvae (14.70) and male beetle (10.40) of C. transversalis and minimum predation was further observed in the 2rd instar larvae (2.50) and no predation was observed in the 1st instar larvae of C. transversalis. Egg predation of C. transversalis by different growth stages of M. sexmaculatus also varied significantly. Among all the stages of M.sexmaculatus, 4th instar larvae were found to be highly voracious towards the heterospecific egg predation. Maximum egg predation, i.e. 24.67 of C. transversalis was observed by the 4th instar larvae of M. sexmaculatus which was on par with the 3rd instar larvae (24.44), followed by female beetle (23.33) and male beetle (16.89) of M. sexmaculatus and minimum predation was also observed in the 2rd instar larvae (7.33) and no predation was observed by the 1st instar larvae of M. sexmaculatus.
