Item Assessment of Stored Flour Types and Effectiveness of Freezing, Sun-Drying and Hermetic Storage in the Management of Red Flour Beetle, Triboliumcastaneum (Herbst) in Ilorin(School of Agriculture and Agricultural Technology, Federal University of Technology, Akure, Nigeria, 2020) Yusuf, R.O.; Ojumoola, A.O.; Uddin II, R.O.; Adesiyun, A.A.Infestation and contamination of flour by the red flour beetle, Tribolium castaneum (Herbst) is a major constraint to flour storage especially in many households of sub Saharan Africa region. Unlike grain protection, flour protection does not lend itself to the use of plant powders, ash, sand and other admixture-based materials often employed by householders in the region as innocuous and cheap alternatives to synthetic insecticides. Scanty information however exists on how effective the few methods used for stored grains insect pest management will be for stored flour. In this study, flour use and T. castaneum management practices of householders in Ilorin, Nigeria was investigated in a survey using questionnaires. Effects of different duration of freezing, sun-drying and hermetic storage treatments on adult and larval mortality of T. castaneum and on population growth in three commonly stored flour types identified during the survey were also evaluated in the laboratory at the Department of Crop Protection, University of Ilorin, Ilorin Nigeria. Furthermore, the effect of each physical method on organoleptic characteristics of treated flour types was assessed. Results showed that semolina, yam and wheat flours were most preferred by householders in the study area. In addition, 12 hours of freezing and 6 hours of sun-drying significantly (p<0.05) caused complete adult and larval mortalities (100.0%) while also preventing population increases in the three most preferred flour types even after 3 months of post-treatment storage. In contrast, hermetic storage treatment for 336 hours caused lower (p<0.05) mean percentage mortalities (6.0% - 16.0%; 7.0% - 12%) and higher post-treatment storage population changes (11.20 – 16.60; 160.60 – 189.80) of T. castaneum adults and larvae respectively in all the flour types. However, none of the treatments negatively affected the organoleptic characteristics of the flours at p=0.05. Information provided in this study will enhance utilization of locally available physical methods for effective management of T. castaneum in the stored flours.Item Comparative efficacy of Azadirachta indica and Moringa oleifera in the control of Callosobruchus maculatus (F.) against stored cowpea (Vigna unguiculata)(Nigerian Journal of Agriculture, Food and Environment.

(Coleoptera: Chrysomeli-dae) Infesting Cowpea Grains(Selcuk Journal of Agriculture and Food Sciences, 2020-11) Ilesanmi, T.O.; Awolola, G.V.; Uddin II, R.O.; Suleiman, Mustapha; Lawal, Mujidat TemidayoSynthetic pesticides usage to prevent cowpea weevils have been reported to be harmful, sometimes leading to the untimely demise of consumers by ingestion of contaminated grains. To save lives, efforts are intensely made to seek after safer alternatives one in particular, is the use of plant based biopesticides. A study was conducted to investigate the effectiveness of N-hexane and ethanol extracts of both sesame leaf and seed and; Trichilia heudelotii leaf to control Callosobruchus maculatus infesting grains of cowpea. Methods employed involved dressing cowpea seeds (100 g) with the botanical extracts at 0 (control), 0.5, 1.0 and 1.5 ml respectively. Next, six pairs of newly emerged adult C. maculatus were introduced into glass vials containing treated seeds in three replicates and observation was conducted for; adult mortality; emergence of larvae, pupae, and new adults of the insect; weight loss of cowpea grains and; qualitative phytochemical screening. Results presented revealed that the N-hexane and ethanol extracts of both sesame and T. heudelotii were significantly (p < 0.05) effective mostly at 1.5 ml in controlling the weevil when compared to the control. Phytochemical analysis indicated the presence of some useful bioactive compounds in the extracts. Observation on weight loss of cowpea revealed that all the various treatment especially at 1.5 ml sustained a significant (p < 0.05) weight compared to the control (40.00±6.67) which was lower. A plausible usage of homemade biopesticide using sesame and T. heudelotii could be suggested as additives to cowpea grains in the control of C. maculatus
