A Potential Repellent Against the Coffee Berry Borer

Research Conducted at Sustainable Perennial Crops Laboratory Has Updated Our Knowledge about Entomology [A Potential Repellent Against the Coffee Berry Borer (Coleoptera: Curculionidae: Scolytinae)]

Fresh data on Life Science Research – Entomology are presented in a new report. According to news reporting originating in Beltsville, Maryland, by NewsRx journalists, research stated, “The coffee berry borer, Hypothenemus hampei (Ferrari), continues to pose a formidable challenge to coffee growers worldwide. Because of the cryptic life habit of the insect inside coffee berries, effective pest management strategies have been difficult to develop.”

The news reporters obtained a quote from the research from Sustainable Perennial Crops Laboratory, “A sesquiterpene, (E,E)-alpha-farnesene, produced by infested coffee berries has been identified as a potential repellent against the coffee berry borer both in laboratory bioassays and a field experiment in Hawaii. Various laboratory bioassays revealed significantly lower levels of infestation in berries treated with different concentrations of the (E,E)-alpha-farnesene. A field experiment in Hawaii resulted in up to 80% decreased coffee berry borer captures in traps containing a standard 3:1 methanol: ethanol attractant and a bubble cap formulation of (E,E)alpha- farnesene compared to traps with just the attractant. (E,E)-alpha-farnesene was still active 19 wk after installation in the coffee plantation, based on 59% lower insect captures in traps containing the attractant + (E,E)-alpha-farnesene (1,737 insects) compared to traps containing the attractant (4,253 insects). The easy to install bubble caps are a welcome contrast with other pest management strategies that require spraying.”

According to the news reporters, the research concluded: “The placement of (E,E)-alpha-farnesene in bubble caps in coffee plantations when coffee berries first become susceptible to infestations (ca. 90 d post-flowering) might result in lower infestation levels throughout the season, and consequently, increased yields and profits.”
