    Comparative Efficacy of Jatropha curcas L. Seed Powder for the Control of Callosobruchus subinnotatus (Pic) on Stored Bambaranut, Vigna subterranea (L.) Verdcourt
    (Department of Agronomy, Nasarawa State University Keffi, 2015-12-12) Dattijo, S.A.; Ajayi, Folorunso A.; Ibrahim, B.I.; Adaebitan, S.A.; Gurama, U.A.; Garba, M.
    The study was to assess insecticidal effectiveness of Jatropha curcas L. seed powder on Callosobruchus subinnotatus (Pic) infesting stored bambaranut, Vigna subterranea (L.) Verdcourt. The experiment was laid out in a factorial design of 4×2 levels (seed powder at the rates of 0.0, 0.5. 1.0 and 1.5 g, with and without addition of the synthetic insecticide at 0.01 g/20 g bambaranut seed) and laid out in a completely randomized design, in three replicates. Results obtained showed lowest oviposition, progeny emergence and seed damage (5.33, 1.58 and 1.83, respectively) in bambaranut seeds admixed with 1.0 g of the seed. Although, statistically similar to all other treatments, it was significantly (P≤0.001) better than the control treatment in which 33.83 eggs were laid and 24.08 adults emerged from 22.92 emergence holes. In addition, at six (6) days after treatment, highest adult mortality rate (99.17%) similar to that (99.17%) obtained in the synthetic insecticide was also recorded in seeds treated with 1.0 g seed powder. However, all other treatments were also significantly better than the control, in which 72.50% of the introduced bruchids died. Comparatively, lowest rate of seed damage (6.68%) and lasting effect was also obtained with the addition 1.0 g seed powder. In conclusion, appreciable level of protection on bambaranut seeds was achieved using seed powder of J. curcas. Therefore, it is recommended that for effective management of C. subinnotatus infesting bambaranut, farmers could use 5 Kg seed powder on 100 Kg bambaranut seeds.

    CONTACT EFFECT OF Jatropha curcas L. EXTRACTS FOR THE CONTROL OF Callosobruchus subinnotatus (Pic) ON STORED BAMBARA NUT, Vigna subterranea (L.) VERDCOURT
    (Department of Agronomy, Nasarawa State University Keffi, 2021-03-02) Dattijo, S.A.; Garba, M.; Ajayi, Folorunso A.; Gurama, U.A.; Hauwa, Y.I.
    The research was conducted in the year 2017 at the Entomology Laboratory of the Department of Crop Protection, Bayero University Kano to assess insecticidal properties of Jatropha curcas L. leaf and seed powders on Callosobruchus subinnotatus (Pic) infesting stored bambara nut, Vigna subterranea (L.) Verdcourt. The study aimed at comparing the effectiveness of the product with conventional chemical insecticide (pirimiphos-methyl 2%). Factorial experiment of 2×2×2 levels (leaf and seed powders at the rates of 0.0 and 0.5 g, with and without addition of the synthetic chemical at 0.01 g/20 g bambara nut seed) were laid out in a completely randomized design and replicated three times. Results obtained indicated positive contact effect of Jatropha leaf/seed extracts on adult bruchids. The results also showed strong repellent both singly and combined treatments although better results were obtained on leaf and seed combination with increase with the time of exposure. In conclusion, appreciable level of protection on bambara nut seeds was achieved using seed powder of J. curcas. Therefore, it is recommended that for effective management of C. Subinnotatus infesting bambara nut, farmers could use 1.0 g seed powder on 20 g bambara nut seeds

    EFFECT OF FUMIGATION OF POWDER LEAF AND SEED EXTRACTS OF JATROPHA CURCAS L. ON CALLOSOBRUCHUS SUBINNOTATUS (PIC) ON STORED BAMBARA (VIGNA SUBTERRANEA (L.) VERDCOURT) NUTS
    (Department of Agronomy, Nasarawa State University Keffi, 2021-11-11) Dattijo, S.A.; Garba, M.; Ajayi, Folorunso A.; Ja'afar, I.A.; Hauwa, Y.I.
    The research was conducted in the year 2017 at the Entomology Laboratory of the Department of Crop Protection, Bayero University, Kano to assess fumigation properties of Jatropha curcas L. leaf and seed powders on Callosobruchus subinnotatus (Pic) infesting stored bambara nut, Vigna subterranea (L.) Verdcourt. The study aimed at comparing the effectiveness of the products with conventional chemical insecticide (pirimiphos-methyl 2%). Factorial experiment of 2×2×2 levels (leaf and seed powders at the rates of 0.0, 0.5. 1.0 and 1.5 g, with and without addition of the synthetic chemical at 0.01 g/20 g bambara nut seed) were laid out in a completely randomized design and replicated three times. Fumigant toxicity effect was observed on the emerged insects, though the result was significantly (P< 0.001) lower. In conclusion, appreciable level of protection on bambara nut seeds was achieved using seed powder of J. curcas. Therefore, it is recommended that for effective management of C. subinnotatus infesting bambara nut, farmers could use 1.0 g seed powder on 20 g bambara nut seeds.

    Insects and Their Products as a Potential Source of Food, Feed and Economic Security: A Review
    (Department of Agronomy, Nasarawa State University Keffi, 2020-01-01) Dattijo, S.A.; Ajayi, Folorunso A.; Garba, M.; Ahmad, M.; Jinjiri, A.
    Due to many ways by which they are exploited, insects and their products could be a very big business. They are sold for agricultural protection, crop pollination, as well as human, livestock and pet nutrition. In addition, their products are sold for pharmaceuticals, health, and the implements for research, art works and a host of other uses. This review focused on commercialization of insects and their products with a view of sharing existing knowledge on global commerce of various insects and their products. Available literature revealed that there was an increase in demand for edible insects in the United States of America and prices were as high as $150 kg-1. Similarly, between 2010 and 2015, animal feed market in the United Kingdom grew at 3.5% annually and is currently worth £5 billion. Because of its scarcity, high demand, and recognition of its healing properties, royal jelly, one of the most sought after from bee products commands astronomical price internationally. In addition, no any other industry could generate high level of employment as sericulture, especially in rural areas where it takes 11 workdays to produce a Kg of raw silk. The contribution insects and their products can give to improve the economy of a developing country such as Nigeria is considerable, but underestimated or neglected. Insects are unlikely to make a major contribution in the near future, but the idea that they are potential source of overcoming the economic problems is not as farfetched as it seemed. Therefore, there is the need to adopt an added value approach to insects and their products and sensitize as well as encourage small-scale farmers, who are disadvantaged in international market participation due to lack of access to information, services, technology or the capacity, to produce larger volumes of quality insect products.
