Abstract:From full bloom to 9 d after fruit set, detection Qfradioactively labeled ("'Zn) plum curculio, ConotTachelu8 nenuphaT (Herbst), in field cages containing three or four dwarf apple trees revealed that the adult beetles were active on the trees mainly during the night. From full bloom to petal fall, they spent most of the day on the ground beneath the trees. As the season progressed the weevils gradually invaded the trees until, by fruit set, most were in the trees. At this time, although they were active throughout the day and night, they were most active in late afternoon and at night. After fruit set, activity was lower than at fruit set and more erratic. Mean daily rate of movement within the cage was positively related to mean daily temperature.
