In the present study, insecticidal activity of Leaves extracts of Lamium purpureum were evaluated as contact toxicants, fumigant and F1 progeny production inhibitors to red flour beetle Tribolium castaneum, the leaves of L. purpureum were collected around Sharada area Kano by hand picking, identified at herbarium of Department of Biological Sceince, Bayero University Kano, washed with clean water, dried under shade, grounded into fine powder using pestle and mortar, extract were obtained by cold percolation using ethanol as solvents, four extract concentrations were prepared using 50% DMSO solution. T. castaneum were obtained from infested flour at A. Rimi market kano, identified by its morphological appearances maintain and reared under ambient conditions (32 ± 0.64°C, 68 ± 3% R.H and 12L: 12D photoperiods) all bioassays were carried out in small transparent plastic containers (4cm height and 6cm diameter). Data generated were subjected to analysis of variance using SPSS (version 20) means were separated at 5% level by Turkey’s tests. Results obtained indicates that leaves extract of L. purpureum were effective as contact toxicant, fumigants and inhibitors of F1 progeny production of T. castaneum hence leaves extracts of L. purpureum has potential to be used as control agent of red flour beetle T. castaneum infesting stored food products. The findings of this study reveal the usefulness of yet another bio pesticide and its incorporation into traditional storage pest management system is recommended.
