wolbachia and impact on sex -

Oct 24,  · The many strains of Wolbachia can do some amazing things to their insect hosts: changing their sex, killing their offspring, and possibly even creating new species. And, in Author: John Timmer. Wolbachia is an endosymbiont bacteria that infects the gametes of up to 76% of the world's insect species, causing such bizarre effects as cytoplasmic incompatibility, male-to-female sex-change, parthenogenesis, and in some cases outright killing off of all male off-spring.

Wolbachia causes the feminization of chromosomally male embryos in several species of crustaceans and insects, including the leafhopper Zyginidia contrast to the relatively well-established ecological aspects of male feminization (e.g., sex ratio distortion and its consequences), the underlying molecular mechanisms remain understudied and by: 6. Jun 17,  · Wolbachia pipientis is a common endosymbiotic bacterium of arthropods that strongly inhibits dengue virus (DENV) infection and transmission in the primary vector, the mosquito Aedes aegypti. For that reason, Wolbachia-infected Ae. aegypti are currently being released into the field as part of a novel strategy to reduce DENV by: 2.

Feb 09,  · Wolbachia have been detected in five butterfly families (Nymphalidae, Papilionidae, Pieridae, Lycaenidae and Hesperiidae), while the family Riodinidea is not reported for infection so far. Wolbachia in butterflies have been concerned in basic biological evolutions such as sex ratio distortion, sperm-egg incompatibility and speciation [31, 32].Cited by: 8.
