UF researchers discover ‘green’ pesticide (methionine) effective against citrus pests

[font size=3]GAINESVILLE, Fla. — University of Florida researchers have discovered a key amino acid essential for human nutrition is also an effective insecticide against caterpillars that threaten the citrus industry.
The Lime Swallowtail, or Citrus Swallowtail, is a well-known agricultural pest from southern Asia discovered in the Caribbean in 2006, and researchers say its potential impact on the U.S. citrus industry is cause for serious concern.
“Everything that’s in the Caribbean eventually gets to Florida – Florida is an invasive magnet,” said UF lepidopterist Delano Lewis, lead author of the study published in the current issue of the Journal of Economic Entomology. “That’s why we’re trying to make the first strike to see how to stop it.”
Experiments conducted on the UF campus at the Florida Museum of Natural History’s McGuire Center for Lepidoptera and Biodiversity and the College of Medicine show when methionine is sprayed on leaves it is 100 percent effective in killing larvae related to the Lime Swallowtail caterpillars within two to three days. If not controlled, the caterpillars can completely defoliate young wild lime plants.
