A pilot program in a 150-acre zone in Miami in 2018 released as many as 375,000 Wolbachia-infected male Aedes aegypti mosquitoes per week for six months and succeeded in reducing the female Ae. aegypti population by more than 75 percent.
New research on bacterial endosymbionts in insects suggests that such bacteria may infect a wide variety of insect species but a low proportion of individuals within those species.
A new study of genetic samples from Aedes aegypti mosquitoes from around the world finds no evidence of naturally occurring infection with Wolbachia bacteria, a positive sign for efforts that artificially introduce Wolbachia to mosquito populations to reduce their numbers or interrupt their ability to transmit disease-causing pathogens.
While many animals, like humans, consume a varied diet to get their necessary nutrition, some insects can extract nourishment from a nutritionally poor food source through symbioses with microbial symbionts.
