The effect of regulating compounds on the growth of Tribolium confusum du Val (Coleoptera: Tenebrionidae)

Abstract : Confused flour beetle, Tribolium confusum du Val (Col.: Tenebrionidae) is one of the most important stored product pests of flour in Iran. In this research the effects of insect growth regulators (IGRs): teflubenzuron, hexaflumuron and pyriproxyfen on oviposition rate, emergence of adults, repellency effects of 17 days-larvae and adults of confused flour beetle have been studied. The results showed that, the highest and lowest of inhibitory reproduction were observed in teflubenzuron (88.5%) and pyriproxyfen (77.4%), respectively. All IGRs significantly were reduced the oviposition rate of T. confusum.The maximum and minimum of inhibitory emergences of adults were observed in Teflubenzuron (86.26%) and pyriproxyfen (75.73%), respectively. Results showed that, reproduction and adult emergences inhibitories were directly correlated with the IGRs concentrations. Repellency effects of IGRs on adults indicated that, the highest and lowest were recorded for teflubenzuron (48.12%) and pyriproxyfen (39.37%). This effect?s experiment on 17-days old larvae showed that, maximum and minimum repellency were in teflubenzuron (47.5%) and pyriproxyfen (36.87%), respectively. These results suggested that IGRs could be used as safe insecticides to control of confused flour beetle
