The High-throughput WAFFL System for Treating and Monitoring Individual Drosophila melanogaster Adults

Abstract

Non-mammalian model organisms have been essential for our understanding of the mechanisms and control of development, disease, and physiology, but are underutilized in pharmacological phenotypic screening assays due to low throughput compared to cell-based systems. To increase the utility of using Drosophila melanogaster in screening, we have designed the whole animal feeding flat (WAFFL), a novel, flexible, and complete system for feeding, monitoring, and assaying flies in a high throughput format. Our system was conceived keeping in mind the use of off-the-shelf, commercial, 96-well consumables and equipment in order to be amenable to experimental needs. Here we provide an overview of the design and 3-D printing manufacture specifications.
