Wolbachia: Reproductive Parasitism and Control Strategies
Wolbachia
&
Reproductive Parasitism
Wolbachia
is a Reproductive Parasite
Assume that the average clutch size is 10 (
5F : 5M
). Record the expected number
of male and female offspring for each arthropod and label the phenotype.
Observation:
Answer with:
Yellow fever mosquitoes are usually uninfected;
therefore, offspring will
develop normally

Wolbachia is a fascinating bacterium known for inducing reproductive parasitism in arthropods, affecting their offspring's sex ratios and survival. This article explores the impact of Wolbachia on different species, genetic crosses, cytoplasmic incompatibility, and vector control strategies such as the World Mosquito Program and Genetic Engineering. Discover the complex interactions between Wolbachia and its host organisms, and the innovative approaches to utilizing Wolbachia for population control and disease prevention.
