ARS Science Key to Stopping ‘Man-Eating’ Parasite

S. Elliott,  Tellus,  2021.
Screwworm infestations were once prevalent in the United States, with 230,000 cases reported in 1935 alone. ARS scientists Edward Knipling and Raymond Bushland conceived and developed the sterile insect technique (SIT) to control and eradicate screwworms. With SIT, sterilized ...

The Sterile Insect Technique: Success and Perspectives in the Neotropics

D. Perez-Staples, F. Diaz-Fleischer and P. Montoya,  Neotropical Entomology,  14. 2020.
Here, we review SIT in the Neotropics and focus on particular recent successful cases of eradication of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), as well as effective programs used against the Mexican fruit fly Anastrepha ludens (Loew), the New World screwworm ...

Study Could Lead to Power Over Parasite

D. Shore,  ,  2020.
Scientists have long had a name for a gruesome insect that feeds on live flesh of warm-blooded mammals: C. hominivorax, Latin for “man eater.” But now, they have the parasite’s number. In a paper published this week in the journal Communications Biology, researchers from ...

Genomic analyses of a livestock pest, the New World screwworm, find potential targets for genetic control programs

M. J. Scott, J. B. Benoit, R. J. Davis, S. T. Bailey, V. Varga, E. O. Martinson, P. V. Hickner, Z. Syed, G. A. Cardoso, T. T. Torres, M. T. Weirauch, E. H. Scholl, A. M. Phillippy, A. Sagel, M. Vasquez, G. Quintero and S. R. Skoda,  Nature Communications,  3:424. 2020.
We identify and analyze the expression of genes that are likely important for host-seeking behavior (chemosensory), development of larvae in open wounds in warm-blooded animals (heat shock protein, immune response) and for building transgenic strains for genetic control programs ...

America’s Never-Ending Battle Against Flesh-Eating Worms

S. Zhang,  The Atlantic,  2020.
The United States Department of Agriculture undertook what would ultimately become an immense, multidecade effort to wipe out the screwworms, first in the U.S. and then in Mexico and Central America—all the way down to the narrow strip of land that is the Isthmus of Panama. The ...

Concept and history of genetic control

Scott, M. J. and Benedict, M. Q.,  Genetic Control of Malaria and Dengue,  2:31-54. 2016.
Genetic control of insects is an established method, mainly for insects that are important crop and veterinary pests such as medflies and screwworm. Efforts to use the same technologies against insects of medical importance, especially mosquitoes, have had limited success. The ...
