Spatial and Temporal Distribution of Oviposition by Plum Curculios, Conotrachelus Nenuphar
Abstract
The spatial and temporal patterns of oviposition of the plum curculio, Conotrachelus nenuphar (Herbst), were established near Gainesville, Florida, by placing suitable host fruit at 3 and 6 ft above the ground in wild plum and oak thickets. Females consistently oviposited more in fruit at the higher level, and they readily located fruit placed in non-host trees. Oviposition occurred from 11 March to 7 October and peaked in early June. Although the plum curculio is considered a multivoltine species in the southeastern U. S., the short period when wild host fruit is available and the relatively long time it takes these insects to complete a generation means that only one major generation is produced each year in north central Florida.Downloads
