In addition to this, the insectary has no pathogens, so there is no chance of encountering infected insects or materials during the visits. Lastly, one of the big advancements in midge rearing was the use of artificial feeders. These blood feeders use sheep blood and artificial membranes made from silicon and nylons to feed the midges, therefore no animals are needed or harmed to provide blood meals.
The open house hosted ~71 people from the USDA Center, Kansas State University, and the wide horizons classes at Manhattan High School. During the tours the visitors were able to see the custom rearing facilities for mosquitoes and midges and saw the incubators that housed the adults (Figure 2) and the rearing racks (Figure 3). The history of ABADRU and their research results were also discussed.
