The microcephaly epidemic in Brazil generated intense debate regarding its causality, and one hypothesised cause of this epidemic, now recognised as congenital Zika virus syndrome, was the treatment of drinking water tanks with pyriproxyfen to control Aedes aegypti larvae. We present the results of a geographical analysis of the association between the prevalence of microcephaly confirmed by Fe...

morphological and electrophoretic analysis of the crystalline inclusions (parasporal crystals) of sporulated cultures of b. thuringiensis ssp. kumamotoensis dsm 6070 (bt 6070) was conducted via phase contrast and scanning electron microscopy and sodium dodecyl sulphate-polyacrylamide gel electrophoresis. the activity of the spore-crystal suspensions against house fly (musca domestica) larvae wa...

Aedes aegypti mosquitoes are responsible for transmission of many viral diseases, such as Zika fever, dengue fever, yellow fever, and chikungunya. Emergence of resistance to currently used pesticides among mosquitoes has increased the importance for the search for novel mosquito control agents. Natural products, particularly plant and microbe derived secondary metabolites, are good sources in t...

BACKGROUND Development of insecticide resistance occurred due to the continuous and misuse of synthetic insecticides therefore, the recent study was conducted to explore eco-friendly plant extracts that have some potential to suppress mosquito larval population. METHODS WHO recommended mosquito larval bioassay method for insecticide was used while for the analysis of citrus oils for limonin a...

The crude extracts of fruits of Sapindus mukorossi, leaves of Cestrum nocturnm, Cestrum diurnum, and Asclepias curassavica were tested under laboratory conditions against Aedes aegypti, a vector of dengue and chikungunya, for their larvicidal properties. Bioassay experiments carried out with crude alcoholic extracts of Sapindus mukorossi, Cestrum nocturnm, Cestrum diurnum, Asclepias curassavica...
