Improved control of the western cherry fruit fly, <i>Rhagoletis indifferens</i> (Diptera: Tephritidae), based on area-wide monitoring

A monitoring program, using spherical wooden traps of Saturn Yellow color, was tested on an area-wide basis for control of the western cherry fruit fly, <i>Rhagoletis indifferens</i> Curran. All calendar sprays were eliminated and substituted by sprays applied only after the first female flies were caught on any of 8 traps/ acre. This approach resulted in elimination of all spray treatments for <i>R. indifferens</i> control in 4 of 10 study orchards during the 1977 season. The remaining study orchards required one fewer spray treatment. In 1978, 1 of 14 study orchards required 4 fewer treatments. Among the remaining orchards, 3 sprays were eliminated in 2 orchards, 2 sprays in 4 orchards and 1 spray in 6 orchards. It is estimated that the average saving in spray costs alone amounted to about $31.00/ acre in 1977 and $26.00 in 1978. The overall reduction in number of sprays applied was about one-half during 2 seasons. The orchard blocks under the fly monitoring program had about the same level of infestation in the fruit as the calendar treatment blocks.References
