The use of chemicals or bio-larvicides for the control of Culex quinquefasciatus and Anopheles stephensi breeding in pit latrines and overhead tanks (OHT) respectively is discouraged owing to many undesirable impacts in the environment. Due to faecal contamination and poor survival, use of predatory fish in OHTs is not feasible. The use of expanded polystyrene (EPS) beads is a potential alterna...

BACKGROUND & OBJECTIVES Malaria is the major health problem in western Rajasthan yet its vector fauna and transmission dynamics thereof is not understood properly. The present investigations report complete profile of qualitative and quantitative aspects of anopheline species occurring in different settings of desert ecosystem. METHODS Area with irrigation through canal for more than 20 years...

Malaria control among nomadic populations has, in the past, posed serious logistic difficulties. Presented in this article are the results of a pilot study in which permethrin was sprayed on the tents of over 26000 nomadic Afghan refugees in an area of Pakistan where seasonal malaria outbreaks occur. In this area Anopheles culicifacies and A. stephensi are the malaria vectors. Population survey...

OBJECTIVE To determine the levels of malathion resistance and prevalence of the malathion carboxylesterase mechanism among mosquitoes in Sri Lanka. METHODS Bioassays were carried out using WHO-recommended methods on samples of the following Sri Lankan mosquito vectors: Culex quinquefasciatus, C. tritaeniorhynchus, C gelidus, Anopheles culicifacies B, A. subpictus, Aedes aegypti and A. albopic...

Development of resistance to DDT in malaria vectors is being reported from various parts of India. Jharkhand state in India is one of the high malaria endemic states with Plasmodium falciparum accounting for 44% of the cases1. In order to find out the rationale of using DDT in vector control, this study was carried out on insecticide susceptibility of malaria vectors in 12 endemic villages of s...

Global climate change can potentially increase the transmission of mosquito vector-borne diseases such as malaria, lymphatic filariasis, and dengue in many parts of the world. These predictions are based on the effects of changing temperature, rainfall, and humidity on mosquito breeding and survival, the more rapid development of ingested pathogens in mosquitoes and the more frequent blood feed...

A field trial was carried out in the Chabahar District of Sistan and Baluchistan Province, southeastern Iran on the efficacy of mosquito nets treated with a suspension formulation of deltamethrin (K-O THRIN) against malaria vectors. Treated nets were used in three villages, and in the two control villages, one used untreated nets and the other used indoor spraying with deltamethrin (WP 10%), wi...
