This is an organizational chart for the “Screw worm educational and control” project Walter is now working on again. You can click to enlarge it. Screw-worm is a type of myiasis caused by C. hominivorax larvae, for those who’ve just joined us. Note that Bishopp is directing the project overall, while Walter is in charge of all of the control activities. At this point, those activities consist mainly of educating farmers about animal husbandry practices to prevent screw-worm infections in livestock. One other name to note: E.F. Knipling, who is now an assistant entomologist in the research branch of this project. In a few years, he’s going to come up with a truly ingenious strategy for controlling this pest. He’ll also be heavily involved in another project that will later shape Walter’s career.
