- Abstract
The herein reported was conducted to evaluate the toxic effect of seven insect growth regulators (IGRs), viz., lufenuron 50EC, flufenoxuron 10DC, pyriproxyfen 10.8EC, tebufenozide 20SC, methoxyfenozide 240SC, triflumuron 20SC, and buprofezin 25%WP against adults of Trogoderma granarium (Everts) and Tribolium castaneum (Herbst). Results revealed that the highest mortality 20.78% was observed when T. granarium adults were allowed to feed on triflumeron treated diet, whereas flufenoxuron was statistically at par with triflumeron having adult mortality 20.23%. The effect of lufenuron and pyriproxyfen was at par with each other having adult mortality 16.59 and 16.18%, respectively. Tebufenozide was the least effective against the adults of T. granarium with 6.63% mortality. In case of T. castaneum the highest mortality was 37.64 and 33.32% due to the effect of triflumeron and flufenoxuron, respectively. Adult mortality of T. castaneum due to the application of lufenuron, pyriproxyfen and buprofezin was 31.16, 22.87 and 18.13%, respectively. Minimum mortality (6.84%) was observed in tebufenozide treatment application. Moreover, the mortality response in case of T. granarium was highest 15.91% when adults were allowed to feed on treated wheat compared to rice and maize with the mortality of 14.80 and 13.79%, respectively. Similarly, the adult mortality of T. castaneum on wheat, rice and maize was 26.36, 23.13 and 19.37%, respectively. It was evident from results that IGRs are comparatively more persistence and effective when applied on wheat than on rice and maize. It is legitimate to concluded that the applications of IGRs have proved to be quite effective against the adults of both species under study. Hence, these compounds particularly flufenoxuron, lufenuron and triflumeron should be considered as potential gears in integrated management of stored grain insect pests.
