Abstract: Solasodine, a glycoalkaloid exhibited growth regulating activity in the last instar larvae of Tribolium confusum.  The larvae were treated with 0.1, 0.25, 0.5, 0.75, 1, 1.5,2, 2.5, 3% concentrations of Solasodine in solvent acetone. Solasodine resulted in marked growth and developmental disruption and inhibition of metamorphosis. The larval development to adults was greatly reduced resulting in the formation of mosaics, deformed pupae, deformed adults due to interference of Solasodine with moulting process and adult eclosion.  The resultant forms were ruled out from further development and reproduction. Our results suggest that Solasodine inhibits growth and development of T. confusum, suggesting its potential as an effective insect growth regulator in integrated pest management modules.
