Insecticidal efficacy of citrus (Citrus spp) peel powder (CPP) against Tribolium castaneum (Herbst) was carried out in the
Department of Zoology and Environmental Biology, University of Calabar, Nigeria. Treatments constituted CPP (orange,
tangerine, lemon, grape and lime) admixed separately with maize grain (popcorn) at different dosages of 1, 2, 3, 4, and 5 g
per 50 g equivalent to 2, 4, 6, 8, and 10 % w/w laid out in completely randomized design with four replications. Parameters
measured included mortality, larval development, adult emergence and weight loss. Sweet orange and Tangerine at 8 and 10
% w/w were efficacious compared to other treatments as they significantly caused higher mortality of T. castaneum, reduced
oviposition, larval development, and inhibited adult emergence as well significantly reduced weight loss. Increase in
concentration resulted to increase in efficacy. Therefore, Tangerine and sweet orange peel powders can serve as a protectant
against T. castaneum at a higher concentration.
Key words: Citrus peel, Tribolium castaneum, mortality, oviposition, popcorn
