Bacillus spp. metabolites are effective in eradicating Aedes aegypti (Diptera: Culicidae) larvae with low toxicity to non-target species.

The growing spread of dengue, chikungunya and Zika viruses demand the development of new and environmentally safe control methods for their vector, the mosquito Aedes aegypti. This study aims to find novel larvicidal agents from mutualistic (endophytic and rhizospheric) or edaphic bacteria that have no action against non-target organisms. Eleven out of the 254 bacterial strains tested were able to kill Ae.

Selective activity of diselenides against Aedes aegypti (Diptera: Culicidae) larvae.

Introduction: Aedes aegypti (L.) is the major vector of arboviruses that causes serious public health concerns in tropical and subtropical countries.

Methods: We examined the larvicidal activity of 1,2-diphenyldiselenide [(PhSe)2] and 1,2-bis(4-chlorophenyl) diselenide [(p-ClPhSe)2] and determine its toxicity to different non-target organisms.

Larvicidal activity of substituted chalcones against Aedes aegypti (Diptera: Culicidae) and non-target organisms.

Background: The expansion of Aedes aegypti (Diptera: Culicidae) population has increased the number of cases of arboviruses, in part due to the inefficiency and toxicity of the chemical control methods available to control this vector. We synthesized 19 chalcone derivatives and examined their activity against Ae. aegypti larvae in order to select larvicidal compounds that are non-toxic to other organisms.
