How Wolbachia spreads
Wolbachia spread within wild Aedes aegypti populations through replacement technique:
Establishment and Spread Mechanism
-
Strain Selection
Wolbachia wAlbB strain originating in Aedes albopictus was selected due to its stability under high temperature and hot climate
-

Mosquito Release Strategy
The strategy to release both male and female Aedes aegypti carrying Wolbachia into dengue hotspots

Maternal Transmission
Wolbachia are passed down naturally from mothers to their offsprings (vertical transmission)

Cytoplasmic Incompatibility (CI)
Wolbachia-carrying male mosquitoes cause cytoplasmic incompatibility when they mate with wild-type female mosquitoes, leading to egg infertility
