Bacillus thuringiensis (Bt) is a bacterium of worldwide interest, due to its high toxicity to a wide range of insect vectors of pathogens to humans and agricultural pests. The insecticidal action of Bt is conferred by the presence of protein crystals, which act as toxins. Several studies are carried out in order to select Bt strains from different ecosystems with mosquitocidal action for vector insects. It is o...

This study relates multiple parameters that are involved in the occurrence and control of malaria in the Amazon. Ebbs and floods, black and white waters, fishponds, and “repiquete” (Amazonian waters phenomenon) influence the density of Anopheles darlingi Root, 1926. The adaptive processes, genetic background, and resilience of Anopheles vectors change in response to climate and environmental changes. This study...
