Smell Science to Snare Screwworm Flies | Portland Maine News
Description
Scientists are unlocking the secret of the New World screwworm’s scent to craft smarter, targeted traps that lure only the pest—no more fly clutter. By zeroing in on the irresistible odor of aging beef liver, researchers hope to isolate the key chemicals that draw female screwworms, cutting down on the tedious work of sifting through thousands of insects. Their goal? A precise lure that not only monitors the pest’s spread but also helps eliminate breeding populations. They’re also redesigning traps to ditch sticky surfaces and make collection easier. The most promising formulas are headed to Panama for real-world testing, while labs in Kerrville keep refining the science—backed by a broader strategy of releasing sterile flies to break the cycle of infestation.
