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...

Vector control is one of the major global strategies for control of malaria. However, the major obstacle for vector control is the development of multiple resistances to organochlorine, organophosphorus insecticides and pyrethroids that are currently being used in public health for spraying and in bednets. Salivary glands of vectors are the first target organ for human-vector contact during bit...

BACKGROUND & OBJECTIVE Though the relationship between mosquito density and transmission of malaria in different regions of the country is known, no studies are available on the relationship between mosquito catches and malaria cases in Kalsi area of Dehradun district in Uttaranchal. Hence, the present study was done to evaluate the role of anopheline mosquitoes catches and prevalence of malari...

BACKGROUND & OBJECTIVES Certain indigenous fish can play potential role in vector control. The study recorded distribution of Aphanius dispar (Rüppell) in its native habitats in Gujarat, India and evaluated its larval propensity for Indian mosquito vectors. METHODS Fishes were surveyed in various districts of Gujarat and samples were collected from coastal habitats and were identified to spec...

It is estimated that every year malaria infects approximately 300 million people and accounts for the death of 2 million individuals. The Plasmodium parasites that cause malaria in humans are transmitted exclusively by mosquito species belonging to the Anopheles genus. The recent development of a gene transfer technology for Anopheles stephensi mosquitoes, using the Minos transposable element m...

Seasonal abundance and tendency to feed on humans are important parameters to measure for effective control of malaria vectors. The objective of this study was to describe relation between feeding pattern, abundance, and resting behavior of four malaria vectors in southern Iran. This study was conducted in ten indicator villages (based on malaria incidence and entomological indices) in mountain...

BACKGROUND & OBJECTIVES Interest in insect glutathione s-transferases (GSTs) has primarily focused on their role in insecticide resistance. These play an important role in biotransformation and detoxification of many different xenobiotic and endogenous substances including insecticides. The GST activity among 10 laboratory selected insecticide resistant and susceptible/control strains of Anophe...

BACKGROUND This study aimed to identify and determine the larval and adult mosquitoes (Culicidae) fauna in Hamedan County, western Iran. METHODS It was a cross-sectional study which took place in four area of the Hamedan County. Sampling methods for larvae, pupae and adults were dipping, hand catch, night catch and total catch. Larvae and adult mosquitoes collected and were sent to laboratory...

OBJECTIVES The objective of this study was to evaluate larvicidal activity of native marine algae against main malaria vector Anopheles stephensi. STUDY DESIGN The total 70% methanol (MeOH) extract and partition fractions of chloroform (CHCl3), ethylacetate (EtOAc), and MeOH from two algae, Sargassum swartzii and Chondria dasyphylla were investigated for larvicidal activities against late III...

A resistant strain of An. stephensi was confirmed to have high resistance to knock down and kill by four different pyrethroids in bioassays in comparison with a susceptible strain. Permethrin, lambda-cyhalothrin and deltamethrin were more irritant to the susceptible strain than the resistant as judged by time for first take-off, but nets treated with alphacypermethrin appeared to be more irrita...
