Malaria is transmitted by Anopheles stephensi and for controlling the malaria parasite Plasmodium spp., the vector mosquito has to be controlled. Extensive use of synthetic and chemical insecticides has resulted in environmental hazards and also in development of physiological resistance among vector mosquito species. Plant products are considered to be a potential alternative approach as they ...

This study investigated proteomic changes occurring in Anopheles gambiae and Anopheles stephensi during adult mosquito aging. These changes were evaluated using two-dimensional difference gel electrophoresis (2D-DIGE) and the identities of aging related proteins were determined using capillary high-pressure liquid chromatography (capHPLC) coupled with a linear ion-trap (LTQ)-Orbitrap XL hybrid ...

Clostridium bifermentans serovar malaysia (C.b.m.) is highly toxic to mosquito larvae. In this study, the following aquatic nontarget invertebrates were treated with high C.b.m. concentrations (up to 1,600-fold the toxic concentration for Anopheles stephensi) to study their susceptibility towards the bacterial toxin: Planorbis planorbis (Pulmonata); Asellus aquaticus (Isopoda); Daphnia pulex (C...

two strains of anopheles atroparvus, one resistant and another sceptible to ddt and two of anopheles stephensi, one resistant and one susceptible to ddt were tested for their irritability to ddt. various laboratory investigations of the effects of insecticides on mosquito behavior and their irritability were carried out. in these series of experiments a comparison was made between the results o...

glutathione s-transferases (gsts) are a major family of detoxification enzymes which possess a wide range of substrate specificities. interest in insect gsts has primarily focused on their role in insecticide resistance. in this study, following world health organization (who) routine susceptibility test, dna was extracted from specimens of anopheles stephensi collected from the kazeroon distri...

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 blac...

We understand little about photo-preference and the molecular mechanisms governing vision-dependent behavior in vector mosquitoes. Investigations of the influence of photo-preference on adult mosquito behaviors such as endophagy and exophagy and endophily and exophily will enhance our ability to develop and deploy vector-targeted interventions and monitoring techniques. Our laboratory-based ana...

We report the identification of genomic sequences in various anopheline mosquitoes (family Culicidae: suborder Nematocera: order Diptera) showing homology to the class II, short inverted-terminal-repeat (ITR) transposable element P from Drosophila melanogaster (family Drosophilidae; suborder Brachycera: order Diptera). Anopheles gambiae appears to have at least six distinct P elements. Other an...

The keratinophilic soil fungus Chrysosporium tropicum was evaluated as a biological control agent against Anopheles stephensi larvae in the laboratory. Culture filtrates of C. tropicum were found to be toxic to An. stephensi larvae at various concentrations. The ranges of the 50% lethal concentration (LC50) values of fungal filtrates were 16.60-17.78, 12.02-12.88, and 34.67-35.48 microl/ml agai...

Use of synthetic pesticides causes some unfortunate consequences such as environmental pollution, pests/ vector resistance and toxicity to other non-target organisms including human beings, biological pesticides from plant, microbial origin are environmentally safe pesticides. Microbial insecticides are especially valuable because their non-toxicity to non-target animals and human beings. Labor...
