Dry femur and ribs of the African humped cow (Bos indicus), rabbit (Lepus spp), goat (Capra hircus), sheep (Ovis aries), dog (Canis domesticus) and pig (Suis scrota) were burnt with fire wood flame. The resulting charcoal was ground aseptically using mortar and pestle and sieved to produce the fine inert dust for the assay. Charcoal dusts of the animals and permethrin powder were comparatively tested at the rates of 0.25, 0.50 and 1.00 % w/w against stored resistant and susceptible maize infested with S. zeamais. Although the charcoal dusts of cow and sheep were best at controlling S. zeamais infestation after matching with the efficacy of permethrin, the potentials of all the charcoal dusts of the mammals should be exploited in the management of weevil infestation in both stored resistant and susceptible maize. Complete suppression of S. zeamais progeny emergence and total grain protection from pest-feeding were achieved with ~0.25 % (w/w) of each of the animal charcoal dusts in resistant maize stored for 54 days. In the susceptible variety however, higher dust concentration of z 0.50 % (w/w) was needed to achieve same result. High mortality and protection achieved by the charcoal dusts may be attributable to weevil cuticular abrasion, active components of the bones and combustion-related factors. Type of maize variety stored and protected with the animal bone charcoal dusts had no obvious impact on weevil mortality at short storage duration of < 5 days. However, at prolonged storage duration of 54 days, varietal effect became conspicuous in terms of adult emergence and grain damage","PeriodicalId":183712,"journal":{"name":"Nigerian Journal of Entomology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114493913","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}

Results showed that Laraforce 2.5EC sprays significantly (P<0.05) lowered population and damage of the Maruca larvae in both the early and late season planted crop compared with the untreated controls.

This study investigated ectoparasites infestation on livestock reared within residential apartments and those sold in the market from August 2014 to September 2015. Visual inspection of the head, neck, abdomen, trunk, leg, tail, pelvic and wings were performed to search for ectoparasites after which physical handpicking technique using forceps and brushing were employed to remove the ectoparasites. A total of 1,032 animals were examined for ectoparasites over a period of twelve months, 792 (76.7 %) of them were reared within residential premises while 240 (23.3 %) were those sold in the markets. The overall infestation rates was 596 (57.7 %) with those being sold in the market having an infestation rate of 70.0%compared to 54.0 %in those reared within residential areas. The infestation of the animals sold in the market was significantly higher than those reared within residential premises. (X2= 3.841, P < 0.05). Level of infestation was higher in female animals, this was however not statistically significant (P <0.05). The animals sold in the market also had higher varieties, this was also not statistically significant (P < 0.05). Boophilus species was the most predominant tick encountered in the study followed by Amblyomma, Rhihicephalus and Hyalomma genera. The predominant species of lice, mites and fleas were Linognathus, Demodex and Ctenocephalides species respectively. The enforcement of already existing prohibition on stray and roaming animals in urban areas will go a long way to preventing spread of infestation in both animals and humans. For the urban livestock farmers, interactive health education, highlighting the zoonotic disease implications of cohabiting with animals will enhance the adoption of more responsible and hygienic animal handling and production.","PeriodicalId":183712,"journal":{"name":"Nigerian Journal of Entomology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122004885","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}

This study was aimed at evaluating the prospects of using ethanol leaf and seed extracts of Picralima nitida in the control of Culex quinquefasciatus and Aedes aegypti, at their larval stages. Fourth instar larvae of test organisms were exposed in static bioassays to the crude extracts of P. nitida. Concentrations tested were 0.15 – 0.75 %w/v, at exposure periods of 24, 48 and 72 hours. At the end of assays (72 hr), the highest concentration (0.75 % w/v) of the ethanol leaf extract of P. nitida resulted in 48.00 and 50.40% mortality of larvae of Cu. quniquefasciatus and Ae. aegypti, respectively. At the same exposure period (72hr) the ethanol seed extract (0.75 %w/v) resulted in larval mortality of 74.40 and 60.80 % for Cu. quinquefasciatus and Ae aegypti, respectively. The 72h LC50 values obtained from probit analysis revealed that larvae of Cu. quinquefasciatus were more susceptible to the seed extract than larvae of Ae. aegypti, with 72 h LC50 values of 0.500 and 0.650 % w/v, respectively. Phytochemical (qualitative) screening of the leaves and seeds of Pnitida detected the presence of alkaloids, cardiac glycosides, saponins and terpenes. In addition, flavonoids and tannins were detected in the seeds. This preliminary investigation has revealed that the leaves and seeds of Pintida hold larvicidal potential. Their formulation as alternatives to synthetic larvicides should therefore be considered.","PeriodicalId":183712,"journal":{"name":"Nigerian Journal of Entomology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122161915","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 factorial experiment consisted of three local eggplant cultivars (Biu Stripped, Biu White, and Biu Green), two insecticides {Endosulfan and Neem Seed Aqueous Extract (NSAE)} and three spray regimes {at 2 weeks after transplanting (WAT), 2 and 4 WAT and at 2,4 and 8 WAT}. Among the three cultivars (Biu Green, Biu stripe and Biu White), Biu Green (BG) showed some degree of resistance to the larvae and had higher fruit yield which makes it the best cultivar. Untreated cultivars had significantly higher number of larvae and higher percentage fruit damage in both 2008 and 2009 rainy seasons. Both Endosulfan and NSAE were better than the control. NSAE performed better in terms of fruit yield and therefore the best insecticide for safer and higher fruit yield. The results also showed that three sprays significantly lowered the number of larvae per plant/plot. The larvae of Eublemma olivacea was found to be damaging young fruits and leave of eggplant in the area. Based on the outcome of this study, farmers can spray their eggplant three times with NSAE for a better fruits yield.","PeriodicalId":183712,"journal":{"name":"Nigerian Journal of Entomology","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134175153","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}
