Examples of diamondback moth in a Sentence

Recent Examples on the Web Anthony Shelton, a professor of entomology at Cornell University, worked with Oxitec on the experimental release of the diamondback moth in 2017. Eric Niiler, Wired, "Can a Genetically Modified Bug Combat a Global Farm Plague?," 24 Sep. 2020 Scientists at Cornell University ran a study comparing Oxitec's diamondback moths with the real thing and to study their affect on a small moth population. Caroline Delbert, Popular Mechanics, "Pesticides Can't Control This Pesky Moth, So Scientists Are Turning To Genetics," 29 Jan. 2020 The diamondback moth has also been resistant to pesticides, the more traditional approach to pest control. Caroline Delbert, Popular Mechanics, "Pesticides Can't Control This Pesky Moth, So Scientists Are Turning To Genetics," 29 Jan. 2020 Pests monitored: Pheromone lures are available for diamondback moths and moths that produce armyworms, cabbage loopers, corn earworms, European corn borers, tomato pinworms, and cutworms. The Editors Of Organic Life, Good Housekeeping, "The 7 Best Organic Pest Control Techniques For Your Garden," 18 Dec. 2017 The diamondback moths are not irradiated, though, because the irradiation strategy didn’t work. Sarah Zhang, The Atlantic, "Genetically Modified Moths Come to New York," 8 Sep. 2017 Researchers from Cornell University are studying whether the engineered insects could be used to reduce the population of the diamondback moth—a European species that has become an agricultural pest in the United states. Jason Daley, Smithsonian, "Genetically Modified Moth May Soon Be Coming to New York Crops," 11 July 2017 Like Oxitec’s mosquitoes, its diamondback moths are genetically engineered to be self-limiting. Sarah Zhang, The Atlantic, "Genetically Modified Moths Come to New York," 8 Sep. 2017 The idea is that as the gene will spread among male moths while continuing to kill female moths—and eventually the diamondback moth population will crumble.
