Storage of grains and their merchandises are significant part of post-harvest maneuvers. Yearly losses of stored grains commodities as a result of numerous biotic factors are noteworthy in financial terms. There is a dreadful necessity to protect the stored cereals and their products against deterioration, particularly the quantitative as well as qualitative losses in storage. The herein reported experimentations were performed to examine the toxic potentials of various insect growth regulators (IGRs), viz., methoxyfenozide 240SC, buprofezin 25%WP, flufenoxuron 10DC, triflumuron 20SC, tebufenozide 20SC, pyriproxyfen 10.8ECandlufenuron 50EC against fertility, fecundity and adult emergence of Triboliumcastaneum(Herbst) and Trogoderma granarium (Everts). Outcomes of the bioassays disclosed that remarkable decrease in fertility and fecundity of the insects was noted as a result of adult contact with IGRs treated diet. Fecundity was notably abridged by application of tebufenozide treatment trailed by methoxyfenozide whereas pyriproxyfen and buprofezin showed slight impact on T. granarium and T. castaneum. The findings concerning to the impact of IGRs treated diet on fertility of adults showed that the pyriproxyfen was remained highly operative in reducing hatching of the eggs while tebufenozide was proven minimum operational for the control ofboth insects. The production of progeny was least in case of pyriproxyfen and highest in tebufenozide for the bioassayed insects. From results of the study, it is determined that use of the IGRs has proven highly operative for controlling the two target insect pests. So, these compound mainly pyriproxyfen,triflumeron, lufenuron and flufenoxuron should be included as an effective constituent in integrated pest management of insect pests of stored commodities.
