    (U. P., 2016-09-05) Mgbemena, I. C.; Ezea, C. O.; Ebe, T. E.; Nwachukwu, A. A.; Nwannah, A. L.
    The study aimed at determining the prevalence of asymptomatic malaria among students of Federal University of Technology Owerri, was carried out between July and September 2015. Blood samples of 160 students who lived both in school hostels and off campus residents were examined using Giemsa stained thick and thin films. A total of 40 students (25%) were infected with Plasmodium falciparium, with an overall asymptomatic case of 11.25%. Students of age 16-22 years had the highest prevalence of 28.28%, with an asymptomatic case of 46.43%, age group 23-29 years had a prevalence of 19.67%, with an asymptomatic case of 41.67%. It was observed that male students had the higher prevalence of 26.15%, with an asymptomatic case of 47.06%, while that of the females was 24.21%, with an asymptomatic case of 43.48%. On the relationship of malaria parasites and genotype, students with genotype ‘AA’ had an infection rate of 27.69%, with an asymptomatic case of 47.22% and students with genotype ‘AS’ had a prevalence of 13.33% with an asymptomatic case of 25%. The result shows that students with blood group O had highest prevalence of 60%, with an asymptomatic case of 61.1%. Blood group A has a prevalence of 27.5% with an asymptomatic case of 27.8%, and Blood group B has a prevalence of 12.5%, with an asymptomatic case of 11.1%, while blood group AB which was 5.62% of the study population had no case of prevalence. Asymptomatic malaria is prevalent in this community as reflected in this study; this could impact negatively on the health of the population. More efforts are needed to encourage public enlightenment on malaria diagnosis and treatment.

    Phytochemical characterization and insecticidal property of Jatropha plant
    (Global Journals Inc. (USA), 2016) Mgbemena, I. C.; Ebe, T. E.; Ezea, C. O.; Irokanjo, C. E.; Okechukwu, R. I.
    Phytochemical analysis on the pulverized leaf sample of Jatropha curcas as well as the insecticidal activity of the ethanolic leaf extract on Callosobruchus maculatus was carried out. The study investigated the mortality rate as a result of treatment of grains with the leaf extract at different dilutions of 20, 40, 60, 80 and 100mg/ml. These were tested against C. maculatus by treating 20g of bean sample with the extract and then infesting each in a plastic container with 20 adults of the insect and the untreated grains were used as the control. The plant extract resulted in a significant increase (P<0.001) in adult mortality at the end of 96 hours but there was no significance difference (P=0.084) after 24 hours. The result had a general dose-response characteristic. There was also significant variation in the phytochemical composition of the plant leaf. Compaared to other phytochemicals, the concentration of saponin and tannin were higher in the plant leaf.
