A Promising Lure May Curb South American Fruit Fly

Controlling damaging Anastrepha fruit flies in their country of
origin before they enter the United States is the goal of cooperative research
between the Agricultural Research Service (ARS) and
ISCA Technologies, Inc.,
of Riverside, Calif.
Anastrepha fruit fly species are a serious pest in many
regions, from northern South America to northern Mexico, penetrating into
southern Texas. Anastrepha species have moved into California, Arizona
and Florida, where growers are especially vulnerable to these flies, which
infest citrus, including grapefruit and oranges, as well as pears, peaches and
C. Robacker of the
Quality and Fruit Insects Research Unit in Weslaco, Texas, previously
worked with a team of researchers from outside companies to develop an
effective synthetic fruit fly lure. When tested on sticky bottle traps, this
lure proved 20 times more effective than standard ammonium phosphate McPhail
traps for capturing South American fruit flies (A. fraterculus). The
lure remained effective for up to 16 weeks.
The lure shows great promise as a tool for detecting and monitoring
Anastrepha species, according to Robacker. It could also be used for
mass-trapping, or at bait stations or kill stations. Future research will
determine if the lure will work in other geographical areas and for other
species of fruit flies.
ISCA focuses on traps and lure-dispensing technologies and seeks new
attractants that target important pests in both urban and agricultural
settings. ISCA will continue to work with ARS to develop an effective and
affordable lure and dispensing combination for this group of fruit flies, and
will field test their formulations in Brazil.
The cooperative research and development agreement between ARS and
ISCA allows for two years in which to jointly develop and market a successful
Anastrepha lure in South America.
ARS is the U.S. Department of
Agriculture's chief scientific research agency.
