    Efficacy of Chrysanthemum cinerariaefolium, Neorautanenia mitia and Gnidia kraussiana against larger grain Borer (Prostephanus trancutus Horn) and Maize Weevil (Sitophilus zeamays Motschulsky) on Maize (Zea mays L.) grain seeds
    (Academic Journals Inc., 2011) Mulungu, L. S.; Ndilahomba, B.; Nyange, C. J.; Mwatawala, M. W.; Mwalilino, J. K.; Joseph, C. C.; Mgina, C. A.
    Studies to evaluate the effectiveness of natural protectants in controlling Prostephanus truncatus and Sitophilus zeamays in stored maize using a Completely Randomized Design (CRD) with three replications. The treatments consisted of natural protectants viz., pyrethrum (Chrysanthemum cinerariaefolium), Neorautanenia mitis, N. mitis with talc as carrier, Gnidia kraussiana powder and untreated control. Actellic Super Dust included as a standard insecticide control. The data collected included the number of dead and live insects, number of damaged and undamaged maize seeds, number of holes per seed, percentage damage and weight loss. Seeds treated with Actellic super dust, pyrethrum and G. kraussiana powder had significantly lower number of live insects and damaged seeds as compared to untreatedcontrol. Among the natural protectants, pyrethrum and G. kraussiana powder showed good potential in protecting maize grain against P. truncatus and S. zeamays. Positive and significant correlations between the numbers of live insects with number of damaged seeds, percentage damaged seeds, average number of holes per seed and weight loss were observed.

    Evaluation of sweet wormwood (artemisia annua l.) as stored grain protectant against maize storage weevil (sitophilus zeamays, motschulsky) and larger grain borer (prostephanus truncatus, horn) on stored maize grains
    (African Journal of Science and Research, 2016) Mwalilino, J. K.; Mwendo, M. M.; Mdangi, M. E.; Mulungu, L. S.
    The objectives of the study were to evaluate the effects of Artemisia annua powder on the mortality of S. zeamays and P. truncatus in the treated maize grain. The experiments were set up as a Completely Randomized Design (CRD) with three replications. The experiments were conducted in SUA Pest Management Centre(SPMC) for 8 weeks. The treatments consisted of different levels of natural protectant A. annua powder (viz: 0.5 g, 1.0 g and 10 g) and untreated control. Actellic Super Dust was included as a standard insecticide control. The data collected included the number of dead and live insects, number of damaged maize grains and percentage damage. Grains treated with Actellic dust, and A. annua powder at all tested levels had significantly controlled S. zeamays insect. Maize seeds treated with Actellic Super Dust surpassed other treatments in controlling P. truncatus due to lower number of live insects and damaged seeds. Artemisia annua at 1.0 g and 10 g had an effect on number of damaged seeds and dead insects as compared to the control. Generally, A. annua powder is effective in controlling these tested storage pest species of maize grains.
