Inside this insectary, at the Uganda Virus Research Institute, a scientist carefully prepares feed for the mosquitoes under their care.
These caged mosquitoes are fed on sugary water and are being constantly monitored by scientists studying their behavior.
Scientists here are investigating whether populations of the malaria-carrying insects can be reduced by genetic modification.
They re looking at the viability of releasing large numbers of genetically modified mosquitos into the wild to influence future generations.
The study is being led by scientists here at the institute in Kampala with researchers from the Target Malaria group.
Dr. Jonathan Kayondo is the principal investigator managing the project.
