Studies conducted with the adult western cherry fruit fly,
Rhagoletis indifferens Curran, revealed that successful oviposition
occurred in three distinct phases, the prepenetration phase, the
penetration phase and the postpenetration phase. During the
postpenetration phase which averaged 51 seconds (range 18 to 86), the
females dragged their ovipositor over the...
Adult emergence studies conducted with Rhagoletis indifferens
Curran reveal that diapause development in this insect is completed
most rapidly at approximately 3°C. These results coupled with those
reported by Brown (1978) confirm that chilling at 3°C. for ca. 200 days
is best when high percent emergence, good synchrony of emergence,...
Air temperatures and soil temperatures at the surface, two inches,
and four inches under a grass cover were recorded over a 93 day period.
These data were used along with other temperature data from bare soil
in the construction of three sets of models for the prediction of
maximum and...
