Barcoded Insect Screens to Optimize Articial Diets

Koen Dechering of TropIQ in The Netherlands will produce an artificial meal for breeding blood-feeding mosquitoes more easily and effectively in the lab. They will develop a high-throughput screening approach using molecular barcodes carried by endosymbiont bacteria that each tag an individual meal consumed by a live mosquito. The barcodes can then be used to identify those meals that best promote egg laying and longevity from a large pool of test foods. They will rationally design the protein and lipid compositions of the test foods for their screen by using mass spectrometry on blood-fed mosquitoes. Optimized diets identified from the screen will be further validated and analyzed for stability also at tropical ambient temperatures.
