or solid particles with a size in the range of 10–1000 nm. Depending upon the method of preparation, nanoparticles, nanospheres or nanocapsules can be obtained. Controlled release and particle degradation characteristics can readily be modulated by the choice of matrix constituents1. Efficacy of Chrysosporium tropicum, a pathogenic fungus mediated silver and gold nanoparticles was reported agai...

Frequent use of synthetic larvicides has led to the development of resistance in many species of mosquitoes as well as risk of environmental pollution. Recently, encapsulating essential oils (EOs) in surfactants or polymers is being employed as an approach to control the volatility of EOs as green larvicides. In this research, components of tarragon (Artemisia dracunculus) essential oil were id...

Aedes aegypti (L.) is known as vector of dengue and chikungunya fever. Larvicides are used to control this vector. We evaluated the efficacy of newly developed formulations of larvicides to control Ae. aegypti under field conditions for 24 weeks post single application. Mosdop P and Mosdop TB containing diflubenzuron (2% and 40 mg/tablet, respectively) as the active ingredient, were applied at ...

Sir,?In the Indian Medical Gazette of (i) January 1938, page 17, (?) April 1938, page 254, (Hi) August 1938, page 468, you published articles and letters on the subject of the breeding places of Siphunculina junicola. Since 24th March, 1937, I have been carrying out an investigation to try and find out the natural breeding places of the Siphunculina junicola fly in this area. I can now report d...

Immature stages of Anopheles bellator and of An. argyritarsis were found in artificial containers. The great number of on-returnable containers now produced, may be playing an important role in the increase in the number of available breeding places for culicid mosquitoes.

OBJECTIVE To assess the contributions of both microbial larvicides and insecticide-treated nets (ITNs) in terms of reducing malaria incidence in an integrated vector management programme in an area moderately endemic for malaria in the western Kenyan highlands. METHODS A pre-post, control group design was used. Larval and adult vector populations were surveyed weekly in six separate valley co...

Environmentally friendly botanical larvicides are commonly considered as an alternative to synthetic larvicides against Aedes aegypti Linn. In addition, mosquito resistance to currently used larvicides has motivated research to find new compounds acting via different mechanisms of action, with the goal of controlling the spread of mosquitos. Essential oils have been widely studied for this purp...
