Begin with a paper cup containing adult mosquitoes, sealed with gauze to prevent their escape.
Place cotton balls soaked in an antibiotic-containing sucrose solution on the gauze, and cover them with a Petri dish to maintain humidity.
As the mosquitoes feed, they ingest the antibiotics, eliminating their endogenous gut microbiota.
Remove the cotton and initiate a starvation period to clear residual antibiotics from the mosquitoes' gut.
Take a tube containing bacteria suspended in a sucrose solution supplemented with a phagostimulant to stimulate feeding.
Take a sealed feeder unit, load it with the bacterial suspension, and secure it.
Connect the unit to a preheated feeding device and place it over the cup containing the pre-starved mosquitoes.
As the mosquitoes feed, bacteria travel into the gut and colonize it, forming a defined bacterial population.
The fed mosquitoes carrying this bacterial population are ready for host-pathogen interaction studies.
Infiltrate the sterile cotton balls in the sucrose solution containing antibiotics and place it over the top of the paper cup containing mosquito.
Cover the cotton balls with a 10-centimeter Petri dish to prevent the water from evaporating. Re
