Sawa, Caleb Obadia","doi":"10.5455/sf.sdabdul","DOIUrl":"https://doi.org/10.5455/sf.sdabdul","url":null,"abstract":"Studies were carried out to examine the insecticidal properties of powdered extract of four plant species, namely Allium sativum (L.) (bulb), Drimia maritima (L.) Baker (bulb), Erythrina senegalensis (L.) (stem bark), and Khaya senegalensis (Desr.) (stem bark), against maize weevil ( Sitophilus zeamais Motschulsky) infestation on stored maize ( Zea mays L.). The efficacies of the plant powders at four levels of concentration (0.5, 1.0, 2.5, and 5.0 g) on maize weevil ( S. zeamais Motschulsky) mortality monitored over 24-, 48-, 72-, and 96-hour intervals were assessed and compared to the industrially formulated insecticide, Coopex (Permethrin 0.5%), using the standard method, respectively. The results obtained revealed that the powdered extract of the four plant species evaluated showed varying degrees of efficacies at certain levels of concentration. The infested maize grain treated with bulb powder of A. sativum (L.) and stem bark powder of K. senegalensis (Desr.) proved to be the most efficacious with recorded lethal doses (LD 50 ) of 0.07 and 0.08 g, respectively, after 24 hours. Bulb powder of D. maritima (L.) Baker and stem bark powder of E. senegalensis (L.) had an LD 50 of 5.10 and 0.20 g, respectively, after 24 hours. On the strengths of these findings, it is evident that A. sativum (L.) and K. senegalensis (Desr.) are potential plant materials for bio-control of maize weevil ( S. zeamais Motschulsky) infestation on stored maize grains.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124087070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is based kerogen pyrolysis, biomarkers, palynofacies and vitrinite refelctance. The total organic carbon (TOC) contents is generally below 1% and thus, classified the samples as having fair to relatively good source generative potential. The kerogen is predominantly of Type III and Type IV indicative of mainly gas with limited liquid hydrocarbon generating potential. Vitrinite reflectance, biomarkers and pyrolysis Tmax indicate that the samples are thermally mature and entered early mature to peak oil window stage. Molecular biomarkers indicates that the samples were deposited under suboxic marine environment with a major contribution of aquatic algae and microorganisms and significant amount of terrigenous organic matter input. This suboxic condition is recognized as one of the controlling factor for the organic matter preservation during the sedimentation. High concentrations of regular sterane C27, indicating suboxic conditions, typical of marine environment of deposition. The high thermal maturities experienced by the samples have influenced the nature of the organic matter thereby cracking them into thermogenic gas due to Tertiary volcanic intrusion konwn to be present in the Yola Sub-basin.","PeriodicalId":128977,"journal":{"name":"Science Forum (Journal of Pure and Applied Sciences)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125517758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
