Efficiency of oviposition traps with biolarvicides for monitoring Aedes aegypti...
Oliveira, Maxcilene da; Silva, Joelma Soares da; Viana, Juliete Lima; Tadei, Wanderli Pedro; Pinheiro, Valéria Cristina SoaresThis study verified the efficiency of ovitraps combined with Saccharopolyspora spinosa and Bacillus thuringiensis israelensis for monitoring Aedes aegypti and Aedes albopictus in laboratory and field conditions. In the laboratory, for A. aegypti, there was no difference in eggs number between treatments and grass infusions. For A. albopictus, the average of eggs was higher in the grass infusion. In the dry seas...
Identification techniques and culture media for the growth of Bacillus thuringi...
Viana, Juliete Lima; Lobo, Katiane dos Santos; Vieira Neta, Maria dos Remédios Araújo; Duarte, Iolanda Cristina Silveira; Delforno, Tiago PalladinoBacillus 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...
