Dengue fever
a virus-based disease spread by mosquitoes
100
What bacterial infection of insects was used for dengue control?
Wolbachia infection
100
How was the Mosquito's fitness tested for the wMEl strain?
Larval development time
100
Gradual diversification of species potentially into new species through a mechanism of natural selection
Descent with Modification
200
How does Wolbachia invade the host?
Cytoplamic incapability
200
A. aegypti embryos microinjection
How was Wolbachia transmitted into the mosquito's cell?
200
What did the semi-field cage system show?
Rapid invasion from relatively small numbers is possible
200
Hierchial organization suggest...?
common ancestor
300
the mosquito that spread dengue fever
Aedes aegypti
300
What induces cytoplasmic incapability in A. aegypti?
wMelPop-CLA infection
300
Why would increased fitness for the infected mosquitoes be beneficial?
The increased fitness would allow the virus resistant mosquitoes to "replace" the naturally occurring wild-type mosquitoes.
