The data showed that Acetamiprid was the most effective against RPW. The effective mixtures against R. ferrugineus were Jujuba oil with Acetamiprid, also used car oil with inorganic salts, which resulted in 100% recovery of treated palm. Continuing treatment of infested palms for 6 consecutive months by injecting used car oil mixed with inorganic saline solution resulted in 100% recovery for both date palm cultivars. Spraying these substances on the affected trunks had no effect on RPW. Pouring the tested solutions around the roots of the affected palm had the least effect against RPW. Injection of the tested pesticides into the ganic salt, compared to the control group. There is a significant difference between the treatments.","PeriodicalId":58873,"journal":{"name":"昆虫学(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70484307","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}

Anopheles funestus sensu lato (s.l.) mosquitoes were identified as species using polymerase chain reaction assay (PCR). Furthermore, Plasmodium falciparum infection status was determined using the enzyme-linked immunosorbent assay (ELISA) leesoni was found positive for P. falciparum (infection rate: 10.98%) in Cameroon. Conclusion: A very high P. falciparum infection rate was observed in this study in A. funestus s.s., highlighting its high implication in malaria transmission in Cameroon.

It is our fervent believe that the contribution of the apiculture sector to its sustainable human development and specifically increases the income of beekeepers and traders of bee products through improved commercialization of quality bee products in Nigeria which will in turn lead to a drastic increase in the GDP of the nation. The overall goal of the Nigeria Apiculture Value Chain (AVC) Development Program is to contribute to an increase income of beekeepers and other actors on the AVC through increase in production capacity, stimulate the efficiency and competitiveness of the AVC products by improving standards, processing capacity so as to access higher value niche markets through Fairtrade International (FLO) certification or organic certifications and to achieve a total sales value of over $5 million by 2035 (Sustainable Development Goal SDG) target on Food Security. Apiculture provides highly desirable products such as honey, comb/wax, pollen, propolis, bee venom, royal jelly, apilarnil and apilanil prop, value added products and pollination services. It is of note to stress the need to urgently embrace the use of modern techniques in keeping honeybees for industrial development of Nigeria and also to enhance exportation of the products to earn growth in the Nigeria’s GDP by diversifying the monolithic economy that is presently based on crude oil exportation.","PeriodicalId":58873,"journal":{"name":"昆虫学(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41566723","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}

Pioneer variety 25R78 is putatively tolerant, meaning that the plant can survive successful Hessian fly infestation with reduced growth effects. To understand if Hessian fly-tolerance in wheat results in reduced yield effects and to analyze the economic feasibility of tolerant wheat as a Hessian fly control method, this study focused on analyzing the effect of infestation on tolerant wheat yield. This study analyzed tolerant Pioneer variety 25R78, resistant Pioneer brand variety 25R32, and susceptible Pioneer brand variety 25R47 through harvest. Treated plants were infested using a plastic cover and allowing 1 - 2 female flies to lay eggs for two hours. We measured head, fertile head number and tiller number. Seeds were analyzed by measuring total seed number and weight, as well as average seed number and weight. Tolerant and resistant plants showed no significant effects on yield in comparison to susceptible wheat. The infested tolerant plants were comparable in yield to infested resistant plants. Therefore, we propose that tolerance incorporated into wheat varieties will lower selection pressure on Hessian fly populations and increase the durability of these wheat lines.","PeriodicalId":58873,"journal":{"name":"昆虫学(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42709158","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}

Using the GC-MS analysis, we observed a compound peak, which could not be identified by comparison to mass spectra in the mass spectral library. This unknown compound was often the largest peak in the chromatogram and had a retention index and mass spectral fragmentation similar to nonanal. However, there were several differences in the fragmentation pattern. When compared to a nonanal reference standard, it was evident that this was a different compound. Hydrodistillation of pony hair was another extraction method to obtain the unknown component in higher concentrations. Analysis of this extract with GC-flame ionization detector (FID) with GC-MS confirmed the same unknown peak.
