Only 40 mg/100 mls of aqueous extracts of Endod leaves of the shoot sourced from Eldoret killed > 80% of exposed L1s.

Crude and only ethyl acetate root extracts of the plant at different concentrations were examined on 1 st - 4 th instars larvae of Cx. quinquefasciatus . LC 50 value of ethyl acetate extract after 24 h of exposure against 3 rd instar larvae of Cx. quinquefasciatus were also examined on some non target organisms. Phytochemical analyses of the root extracts of A, reticulata were also investigated. 100% mortality were noticed at very low concentrations of petroleum ether, hexane, and ethyl acetate root extracts of A. reticulata against 3 rd instar larvae of Cx. quinquefasciatus . LC 50 and LC 90 values of ethyl acetate root extract was lower than petroleum ether and hexane root extracts after 24, 48, and 72 h of exposure. Crude and ethyl acetate root extracts showed excellent larvicidal activity against Cx. quinquefasciatus mosquito species. 100% mortality was observed at very low concentration for crude and ethyl acetate root extracts. LC 50 and LC 50 values gradually decreased with time of exposure for crude and ethyl acetate root extracts of A. reticulata . No mortality and sluggishness were observed in control experiments as well as on examined non target organisms.

Given that avoidance may be a viable option to decrease exposure to infected mosquitoes, we conducted a study to determine the biting patterns for mosquitoes during the 12 hour period from 18h00 to 06h00. Host-seeking mosquitoes which landed on the exposed legs and hands were collected using a mouth aspirator. Mosquitoes were continuously collected during the first 50 minutes of each hour and rested for the remaining 10 minutes. The hourly catches of mosquitoes were kept in labeled cups according to the hour of collection. A total of 711 mosquitoes from three genera and seven species were collected. Four species belonged to Culex , two to Mansonia and one to Armigeres . Among the collected species, six were recognized as vectors of pathogens in Bangladesh including the vectors of filariasis [ Culex quinquefasciatus (56.54%), Mansonia uniformis (15.75%), Mn. annulifera (12.38%), and Armigeres subalbatus (4.64%)] and Japanese encephalitis [ Cx. tritaeniorhynchus (7.17%), and Cx. vishnui (1.55%)]. One non-vector species of mosquito, Cx. hutchinsoni (1.97%), was also collected during the study. In general, biting commenced just after sunset, increased gradually, peaked between 24h00 and 01h00 and decreased to the lowest level between 05h00 and 06h00. The biting densities of mosquitoes ranged from 9.1 mosquitoes per men hour (mph) in July to 16.5 mph in May, with an overall average of 11.85 mph. The highest and lowest biting density was found in May and July respectively. Biting activity of various vector species differed during different hours in the night. Use of personal protection methods should be encouraged during the peak biting times to minimize vector-host contact.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70856922","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}

Laboratory investigations were carried out to evaluate the impact of extracts; prepared from the stems and leaves of Achyranthes aspera; on the survival, behaviour and morphology of Ae. aegypti larvae. Healthy and disease-free parts of A. aspera extracted in hexane were screened for their larvicidal activity against early fourth instars of dengue vector in accordance with the WHO protocol. The investigations clearly established the larvicidal efficiency of both the extracts, though hexane stem extracts proved to be 0.82 fold more efficient than the leaf extracts. The bioassay resulted inLC 50 value of 68.133 and 82.555 ppm, when larvae were exposed to the hexane stem and leaf extracts of A. aspera , respectively. On the other hand, at LC 90 level, the hexane leaves extract proved to be 18% more efficient as compared to the hexane stem extract of A. aspera. Behavioural observations of the treated larvae revealed excitation and restlessness with persistent and aggressive anal biting behaviour indicating the probable effect of the extracts on the neuromuscular system of larvae. Microscopic observations of the dead larvae showed shrunken internal membrane of anal papillae and abnormally stretched body. Further the treated larvae of Ae. aegypti showed distorted alimentary canal with loss of pigmentation and partial or total cell destruction. Our results suggest the probable use of hexane extracts of A. aspera as an efficient and eco-friendly larvicide against Ae. aegypti . Further investigations are needed to identify the bioactive constituent and ascertain its effectiveness in the field conditions .","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70856873","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}

Larval mortality toxicity was calculated after 24 hours exposure period and the results obtained show that all the extracts exerted varying significant (P<0.05) percentages of larvae mortality effect; extract of C. gigantea was found to have the highest mortality rate at LC 50 and LC 90 . From the phytochemical screening conducted on the plants, it was observed that the plants contain some secondary metabolites which are likely responsible for the larvicidal properties exhibited by the tested plants.
