“…uniformis was the most abundant among the Mansonia species and is a vector of both filariasis and JE. 21,22 More than half of the mosquito collections in the present study were potential vectors of both JE and filariasis. Aedes albopictus, which formed 0.05% of the mosquito samples is an important vector of many arboviral diseases such as dengue and chikungunya.…”

a b s t r a c tBackground: Vector monitoring in military stations would help in protecting the armed forces from vector borne diseases such as malaria, Japanese encephalitis and filariasis.Methods: Adult mosquitoes were collected from four villages around a military station in India using light traps and the species composition was estimated. Insecticide susceptibility of disease vectors against DDT, deltamethrin and permethrin was established using WHO kits.Results: The known malaria vectors constituted 4.9% of the total mosquito collections and Anopheles philippinensis/nivipes (2.05%) was the most abundant. Japanese encephalitis and dengue vectors constituted 25.3 and 0.05% whereas the known vectors of both Japanese encephalitis and filariasis formed 50.9%. The mean (AESE mean ) of annual parasitic index, slide positivity and Plasmodium falciparum percentage among the civilian population during the study period were 1.46 AE 0.37, 1.65 AE 0.77 and 50.2 AE 10.7. The filariasis vector Culex quinquefasciatus was resistant to DDT with 65.4% mortality whereas the DDT resistance in the Japanese encephalitis vector Culex vishnui gr. with 91.9% mortality needs to be confirmed. All other species tested were susceptible to DDT, deltamethrin and permethrin.

“…The Culex quinquefasciatus is a major public health problems in India and filariasis is potentially risk of infection [2] These diseases affect the health and quality of life of millions of people in Worldwide [3]. An estimated 120 million people in tropical and subtropical areas of the world are infected with lymphatic filariasis [4].…”

Objective: The present study was undertaken with the aim of finding out the efficacy of essential oils (EOs) as anti-mosquito agents for commercial purposes. Plant source insecticides as an alternative to chemical insecticide, this study were evaluated to assess the knock-down and adulticidal prospective of the essential oils against Culex quinquefasciatus. The plant essential oil is largely cultivated throughout India and in all Tropical countries. Methods:The selected botanical essential oils were procured from commercial producers of plant essential oils and aromatic substances were used in this study. Knock-down and Adulticidal bioassay was performed according to WHO protocol. A single dose of the essential oils was used in the preliminary screening. 20 adult mosquitoes (3-5 d old glucose fed mosquitoes) were exposed on treated paper for one hour and knocked down and live mosquitoes were counted at 5 minute intervals. Results:Among the twenty three oils tested, 100% knock-down and adult mortality was recorded at 10%/cm 2 dose of calamus, camphor, cinnamon, citronella, clove, eucalyptus, lemongrass, pine, thyme and tulsi oils respectively. At 10 % concentration, clove oil (KT50 =1.8 and KT90 = 2.03 min) was found to be the most potential treatment. After 15 min exposure period clove oil registered the lowest knock-down dose which was calculated as (KD50 =1.8 %/cm 2 and KD90 =11.2 %/cm 2 ). The lower and upper 95 % confidence limits for clove oil were calculated as 0.2 and 4.2 min respectively. Conclusion:From the results it can be concluded that the adult of the Cx. quinquefasciatus were susceptible to the essential oils. Such findings would be useful in promoting research aiming at the development of new agent for mosquito control on basis of chemical compounds from indigenous plant sources as an alternative to chemicals.

“…Another mosquito species Culex quinquefasciatus is the principal vector for Wuchereria bancrofti, the filarial worm that causes filariasis and Japanese encephalitis (Agrawal and Sashindran, 2006). Lymphatic filariasis is a major public health problem worldwide.…”

Midgut symbiotic bacteria are known to play fundamental roles in the biology of mosquitoes, however knowledge of midgut bacterial communities associated with mosquitoes is scanty due to limitation of the isolation techniques based on culturing. In this study, the composition and diversity of midgut bacteria in field collected and lab reared adult female Anopheles gambiae and Culex quinquefasciatus mosquitoes was explored using the Illumina sequencing. Deoxyribonucleic acid was isolated from the pooled midgut extracts and their 16S rRNA gene sequenced using Illumina sequencing platform. Operational taxonomic units (OTUs) were analyzed using QIIME 1.8.0; taxonomy was assigned using BLASTn against SILVA 119 and hierarchical clustering was done using R program software. Out of the total number of sequence reads obtained, 145 OTUs were realized at 3% genetic distance. ). The bacterial composition and diversity appeared to be influenced by the environment and the species of the mosquitoes.
