The best way to control mosquito borne diseases is to control the mosquito population. The present study was executed to evaluate the mosquito larvicidal activity of Nicotiana plumbaginifolia leaves against malarial vector Anopheles stephensi.Crude extracts and three different solvent extracts were bio-assayed against An. stephensi larvae. LC50 and LC90 values were determined appropriately. Qua...

Bioactive molecules of plant origin play a significant role as defensive agents in different insect species. Chemical compounds medicinal plants have been an exciting alternative to standard methods controlling mosquito larvae. The present study evaluates the solvent extracts D. hamiltonii for toxicity against three Bioassay revealed that effect methanol increased larval mortality with increasi...

Successful development of Plasmodium in the mosquito is essential for the transmission of malaria. A major bottleneck in parasite numbers occurs during midgut invasion, partly as a consequence of the complex interactions between the endogenous microbiota and the mosquito immune response. We previously identified SRPN6 as an immune component which restricts Plasmodium berghei development in the ...

Background: Mosquitoes are responsible for the transmission of many pathogens and parasites and consequently serious diseases in humans. Currently, application of plant derivatives has been suggested as an alternative bio-control technique for these medically important vectors. Methods: In this study the essential oil and methanol extract of Achilleaw...

possibilities. During a study of village malaria in Mysore State (Sweet, 1937), several anophelines were studied, including A. stephensi, from various parts of the State, but no evidence of races of Indian anophelines based on egg patterns could be found and it was concluded that other methods to distinguish possible differences would have to be used. Such a new approach to the subject was sugg...

tagetes minuta l. is considered as an annual plant growing in the temperate zones of south america. it has been used as carminative, anti-inflammatory, anti-abortion,vermifuge, bronchodilator and hypotensive. in the current study the locally cultured plant of tagetes minuta l. was studied for phytochemical and larvicidal properties.the phytochemical analysis of aerial parts of the plant exhibit...

Vector borne diseases are affecting millions of people annually. Entomopathogenic fungi toxicity on malaria vectors increase mortality rates, and are less effective on nontarget organisms, thus representing a control measure that could be used in integrated programmes. Before metabolites of entomopathogenic fungi can be integrated into control programmes, an effective delivery system must be de...

BACKGROUND & OBJECTIVES Anopheles stephensi, an important vector of malaria continues to be distributed widely in the Indian subcontinent. The natural vigour of the species combined with its new tolerance, indeed resistance to insecticides has made it obligatory that we look for control methods involving genetic manipulation. Hence, there is an immediate need for greater understanding of the ge...
