摘要

In choice tests, blueberry maggot Rhagoletis mendax Curran flies were exposed to blueberries or marbles (surrogate berries) in a highbush blueberry Vaccinium corymbosum L. planting. Significantly more R. mendax flies were attracted to cages baited with blueberries compared with marbles. In additional experiments, five volatile compounds consisting of butyl butanoatc, cis-3-hexen-l-ol, alpha-terpiniol, geraniol, and trans-2-hexenal were extracted and identified from ripening blueberries using gas chromatography and mass spectroscopy (GC-MS) techniques. Late in the season, butyl buianoate and cis-3-hexen-1-ol were as attractive to R. mendax as ammonium acetate (1BEEM~(R)capsule). Increasing the load-rates of butyl butanoate and cis-3-hexen-l-ol did not significantly increase trap captures.
