                                    Citation: Yee, W.L. 2002. Status of Tephritid fruit fly control. Washington State Horticulture Association Proceedings.p.168-172.Interpretive Summary: Abstract only for proceedings
                                Technical Abstract: Current control of the two major tephritid fruit fly pests in Washington and the Pacific Northwest, the western cherry fruit fly, Rhagoletis indifferens, and the apple maggot, Rhagoletis pomonella, is based almost entirely on insecticide use.  To develop alternatives to, or, more realistically, to augment  insecticide-based control, the biology and ecology of both flies need to be fully understood.  Studies are being conducted at the Yakima Agricultural Research Laboratory to better understand the flies and to test methods for their control and detection. Studies with the western cherry fruit fly deal with the effects of a cherry diet on fly longevity and fecundity, the daily and seasonal activities of flies, fly mating behavior, and the effects of nematodes on fly mortality.  Studies with apple maggot  deal with the effects of ammonia on trapping flies and re- evaluation of host usage by the fly in Washington.  A study testing the efficacy of the brown sugar flotation technique for detecting western cherry fruit fly larvae is also being conducted.
