BACKGROUND & OBJECTIVES A strain of Bacillus amyloliquefaciens (VCRC B483) producing mosquito larvicidal and pupicidal biosurfactant was isolated from mangrove forest soil. The present study was aimed at studying the kinetics of growth and production of the mosquitocidal biosurfactant by this bacterium. METHODS Dynamics of growth, sporulation and production of mosquitocidal biosurfactant were...

Methanolic extracts of leaves and seeds from the chinaberry tree, Melia azedarach L. (Meliaceae) was tested against mature and immature mosquito vector Anopheles stephensi Liston (Diptera) under laboratory condition. The extract showed strong larvicidal, pupicidal, adulticidal, antiovipositional activity, repellency and biting deterency. The M. azedarach seed and leaf extracts were used to dete...

Two of the most important challenges facing humanity in the 21st century comprise food production and disease control. Eco-friendly control tools against mosquito vectors and agricultural pests are urgently needed. Insecticidal products of marine origin have a huge potential to control these pests. In this research, we reported a single-step method to synthesize silver nanoparticles (AgNP) usin...

INTRODUCTION Aedes aegypti is responsible for the transmission of the dengue and yellow fever viruses. This study evaluated the effects of extracts from Cnidosculos phyllacanthus, Ricinus communis, and Coutarea hexandra on the developmental periods of A.aegypti larvae and pupae. Crude extracts of C. phyllacanthus and C. hexandra and oil from R. communis and C. phyllacanthus were used. METHODS...

The pink bollworm Pectinophora gossypiella is one of the most destructive insects attacking cotton fields world-wide. The present study was conducted to evaluate the survival and developmental effects of the novel chitin synthesis inhibitors (CSIs), Noviflumuron and Novaluron, on this insect pest, after treatment of 1-day old eggs. These CSIs exhibited ovicidal activities on eggs, in a dose-dep...
