Staphylococcus hominis is a culturable component of the bacterial microbiome of Anopheles stephensi. Here, we present the annotated draft genome sequences of three S. hominis isolates from A. stephensi. These genomic resources will facilitate experiments to further our understanding of the role of bacteria in mosquito biology.

BACKGROUND There are several plant extractions which are being used for mosquito control. The aim of this study was to evaluate the efficacy of Olea vera, Linum usitatissimum and Piper nigera against Anopheles stephensi and Aedes aegypti under laboratory conditions. METHODS These tests were carried out using WHO recommended bioassay method for adult mosquitoes. RESULTS The extracts from bla...

Background and purpose: Insecticide resistance in mosquitoes particularly malaia may lead to reemergence of malaria epidemics. This study aimed to investigate the effect of oral and intramuscular administration of ivermectin on guinea pigs exposed to Anopheles stephensi mosquitoes, the main malaria vector. Materials and methods: The effect of ivermectin was studied in oral and intramuscular ad...

Rabbit antibodies to five antigens (AJ** 29, 35, 43, 64, and 80 kDa) derived from the ovaries of Anopheles stephensi tended to reduce the number of eggs produced. Ingestion of anti-mosquito ovary antibodies did not show a detectable effect on the mortality of mosquitoes. Antisera raised against An. stephensi ovaries showed cross-reactivity in other tissues and in the ovaries of other Anopheles ...

Anopheles (Cellia) stephensi Liston is a major vector species of malaria in Indian subcontinent. Taxonomists have worked on its various morphological aspects and immature stages to explore additional and new taxonomic attributes. Scanning electron microscopic (SEM) studies have been conducted on the fourth instar larva and pupa of An. stephensi to find additional taxonomic features for the firs...

Anopheles stephensi, a major vector for malaria parasite transmission, responds to Plasmodium infection by synthesis of inflammatory levels of nitric oxide (NO), which can limit parasite development in the midgut. We have previously shown that Plasmodium falciparum glycosylphosphatidylinositols (PfGPIs) can induce A. stephensi NO synthase (AsNOS) expression in the midgut epithelium in vivo in a...

 Introduction: Malaria is still one of the most important communicable diseases in the world. The main measure for vector control is using insecticides as residual spraying and recently impregnated bednet with pyrethroid insecticides. Comparative study on the efficacy of pyrethroid impregnated torn bed nets (lambdacyhalothrin and bifenthrin) and Deet against malaria vector, Anopheles stephensi,...

Larvicidal activity of pectolinaringenin from Clerodendrum phlomidis was evaluated against Anopheles stephensi and antifeedant, larvicidal and growth inhibitory activities were evaluated against Earias vittella. Pectolinaringenin exhibited larvicidal activity of 100 and 98.24% against 2 nd and 4 th instar larvae of Anopheles stephensi at 5ppm concentration. It exhibited LC50 values of 0.35 and ...

The objective of the present study is to determine the bioefficacy of different crude extracts of Ajuga remota against anopheline and culicine larvae. Larval susceptibility of crude carbon-tetrachloride, methanol and petroleum-ether extracts of Ajuga remota leaves was observed against the malaria vector, Anopheles stephensi and the filariasis vector, Culex quinquefasciatus. Among the extracts t...
