Several methodologies have been developed to control those vectors as means to get rid of those diseases with least hazardous effect on environment. The aim of the present study is to evaluate the potentiality of leaf extract of the plant Alangium salvifolium as larvicide, pupicide as well as smoke toxic agent against Culex vishnui group mosquitoes. Various concentrations of crude and Chloroform: Methanol (v/v 1:1) extracts of leaves of A. salvifolium were prepared and applied against each of four successive instars larvae and pupae. In another study the smoke toxicity effect was studied after preparation of the mosquito coils from air dried leaf of the plant. First instar larvae showed 100% mortality at 0.5 mL crude concentration in 24 h. followed by second instar larvae (86.67%) and lastly fourth instars larvae (56.67%). 13.33% death rate was observed for the pupae with same concentration of crude extract. The LC 50 and LC 90 values of the solvent extract were 48.89 and 71.78 ppm respectively. The plant based mosquito coil exhibited 32% mortality against adult mosquitoes within 3 hr. No negative impact was observed on non-target organisms.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70857400","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}

Aedes aegypti causes certain diseases like dengue, yellow fever andchikungunya. There are no effective vaccines and drugs available for those diseases. The control of Aedes aegypti is the only effective way for prophylyxis from this disease. Radiation has played an important role in insect pest management. To determine the radio sensitivity, an experiment was conducted to understand the effect of γ - radiation at higher doses on immature stages of Aedes aegypti. One day old pupae were irradiated with variable doses between 100Gy to 1000Gy to study the pupal viability, adult emergence and development of malformation if any. The dose response curve between the pupal viability and dose was determined and there was a marked difference in radiation sensitivity . It was observed that the pupal viability decreased with increase in radiation dose in dose dependent manner. Pupal viability of about 99.2%, 61.4%, 42.5%, 13.4%, 7.5%, 6.7% and 3.9% was found after exposure to gamma radiation at 100Gy, 250Gy, 400Gy, 550Gy, 700Gy, 850Gy and 1000Gy respectively. Similarly, adult emergence was also drastically affected by radiation exposure. The percent adult emergence from irradiated pupae were about 99.2%, 61.3%, 42.4%, 13.4%, 7.2%, 6.4%, and 3.0% at 100Gy, 250Gy, 400Gy, 550Gy, 700Gy, 850Gy and 1000Gy respectively. Morphological deformities on both pupae and adult of Aedes aegypti were noticed after irradiation indicates the somatic damage of pupae and adults. It was observed that head, thorax and part of the abdomen with fore wings were released but the rest of the body still attached to the puparia. Similarly, few malformed adults with curled legs, crumpled wings and with curved abdomen were obtained due to the effects of high dose of gamma radiation at 400Gy and above.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70857737","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}

In this study we demonstrate adulticidal effect of ethanol extracts of mature green fruits and leaves of Endod on Anopheles gambiae adults in the laboratory. Material & Methods: Different concentrations (80, 40, 20, 10, 10, 5 and 2.5 mg) of Ethanol extracts of leaf and mature green fruits of Endod, Neem and deltamethrin were used to impregnate standard Whatman No. 1 filter papers and wall surfaces. Wall surfaces were modeled from plywood measuring 26 x 26 cm 2 . The surfaces were then smeared with a mixture of mud and cow dung, cement or used as it were (plain). Three to five day old laboratory and field sourced female An. gambiae were then exposed for five minutes, withdrawn put in clean paper cups and left to be observed for mortality after 24 hours. Results: Mortalities of exposed female An. gambiae were higher for extracts of Endod sourced from the highlands than that from the lowlands for laboratory reared (60%) and (40%) and field sourced (30%) and (28%) respectively. Mortalities were higher on modeled surfaces (61%) than on Whatman No. 1 papers (30%). Toxicity level of extracts of Endod were below the WHO threshold of >80% mortality irrespective of part or source. Deltamethrin met the threshold on all surfaces while Neem on cement surfaces only. Conclusion: Ethanol extracts of mature green fruits and leaves of Endod are a potential adulticide against An. gambiae adults.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70857328","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}

Insecticides of botanical origin may serve as suitable alternative in near future. In the present study, crude plant extracts of 32 commonly available plants were evaluated at different concentrations against third instars larvae of Culex quinquefasciatus to establish their mosquito larvicidal activity. Methods : Three different Concentrations (0.1, 0.5 and 1.0%) of crude extracts were prepared from selected plants and observed larval mortality after 24h, 48h & 72h of post exposure against third instars larvae of Cx. quinquefasciatus . LC 50 and LC 90 were determined by using log-probit analyses. Effects on non target organisms were also tested. Result : Among the tested concentrations, highest mortality was recorded at 1% concentration of crude extract within 72 hours of exposure in all plant extracts. In laboratory based larvicidal bioassay, lowest LC 50 and LC 90 values were recorded in fruit extracts of Solanum nigrum and Solanum sisymbrifolium respectively. Mosquito larvicidal property of Clerodendrum viscosum , Cleome viscosa, Alangium salvifolium, Murraya k oenigii, Polyalthia longifolia and Derris indica were also satisfactory. Tested non-target organisms were entirely safe against the tested concentrations during study.

A morphometric analysis was carried out to characterize the morphology of adult females An. arabiensis and to test the existence of morphological variations among local populationsof females An. arabiensis found in eastern Sudan.Adult females An. arabiensis were collected from four sites in Kassala State, eastern Sudan (Kassala, New Halfa, Aroma and Wager). In addition, An. arabiensis specimens, obtained from Sennar laboratory colony were also used in the study. Collection of females An. arabiensis mosquitoes was done by hand capture during the rainy season 2008. Thirty seven morphological characters were examined on samples representing each of the collection sites. One Way ANOVA testshowed significant differences in most of the measured characters on females An. arabiensis . Principal component analysis showed that the populations studied differed mainly in the body size of mosquito. A discriminant function analysis was used, based on the new variables generated by principal component analysis, to select an aggregate of morphological characters which collectively could differentiate local populations of females An. arabiensis and to assess the reliability associated with multivariate statistics. Using the body size measurements, the analysis revealed that geographical clustering of field collected females An. arabiensis populations were not clear and the body size characters had little discrimination values. The cluster analysis summarized the phylogenetic relationships among the different populations of An. arabiensis according to their mean body sizes . Laboratory colony samples had a smaller body size compared to the field collected ones. The morphometric analysis confirmed the existence of some geographical variations in the mosquito body size among local populations of An. arabiensis in eastern Sudan.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70857470","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}

We evaluated laboratory bioassay of Chilodonella uncinata , a natural protozoan parasite of mosquito larvae. Methods Two formulations and four strains: North India (Monsoon and Pre-monsoon) strain, South India strain, updated strain of Chilodonella uncinata were tested against Anopheles stephensi , Culex quinquefasciatus and Aedes aegypti larvae at four institutes. Results & Interpretation Delayed development was noted in mosquito larvae exposed to Ch. uncinata formulation that produced better effect in all larval species. Efficacy of this biolarvicide is not dose dependant as least dose produced maximum mortality with minimum post exposure. An. stephensi larvae were most sensitive followed by Cx. quinquefasciatus and Ae. aegypti which required longer post exposure. Of the four strains, updated strain was most effective and stable; south India strain had rapid killing effect; Pre-monsoon strain was more effective than Monsoon strain as the later required 20x higher dose (cs/ml) to induce satisfactory mortality in An. stephensi larvae with higher values for LT 50 (4.71) and LT 90 (6.84) as against LT 50 (2.5) and LT 90 (3.57) of former strain. Tea bag formulation is easy to store, transport and treat, was found to have a shelf life of >18 months resulting in satisfactory efficacy against An. stephensi with LT 50 (5.16) and LT 90 (7.69) noted at 0.25 g even after 6 months of storage. These laboratory test data suggest that a lower dose of this protozoan formulation can be used as a potential biolarvide to control mosquito larvae as an alternative to chemical insecticides under integrated vector management.","PeriodicalId":92079,"journal":{"name":"Journal of mosquito research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70857674","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}
