Hannah Burrack, North Carolina State UniversityUnlike many other fruit flies, spotted-wing drosophila prefer fruit that is just reaching maturity. The invasive spotted-wing drosphila can be a picky eater at times.
Research led by North Carolina State University entomologist Hannah Burrack shows the pest prefers certain varieties of raspberries and blackberries over other varieties, according to a news release.
That means growers could reduce some of the damage the fly causes by avoiding those preferred varieties.
Along the same line, growers could focus their control campaigns more on the susceptible varieties.
The three-year study looked at spotted-wing drosophila preferences in commercial fields as well as in laboratory experiments.
An article detailing the research, "Variation in selection and utilization of host crops in the field and laboratory by Drosophila suzukii Matsumara (Diptera: Drosophilidae), an invasive frugivore," was published in the March 14 issue of Pest Management Science.
