Wolbachia is an intracellular bacterium, which naturally infects a number of mosquito species that are important vectors of human diseases, including Aedes albopictus, Culex quinquefasciatus and Cx. pipiens. Recent evidence suggests that Wolbachia can induce resistance to pathogens in mosquitoes, modifying their ability to transmit them. It is common for Wolbachia densities to vary in different Wolbachia: host relationships, and among adult individuals collected in the field from the same host population. It has been observed that this variation in bacterial density correlates positively with the degree of resistance to pathogens. In this work, real-time PCR technique was developed for the determination of the levels of variation of Wolbachia density in Aedes albopictus according to the tissue in which the infection is lodges, the sex and age of the host insect.
