| Abstract:
Cranberry tipworm, Dasineura oxycoccana Johnson (Diptera: Cecidomyiidae) is a key pest of rabbiteye blueberries, Vaccinium ashei Reade, in the southeastern United States. In an attempt to develop monitoring protocols for detecting D. oxycoccana in blueberry fields, four colored (yellow, white, green, and blue) sticky traps were evaluated for monitoring D. oxycoccana. There was no significant difference in attraction of D. oxycoccana to colored sticky traps. In a separate study, three sampling techniques (unbaited yellow sticky boards, bud emergence and bud dissection) were evaluated for their effectiveness in detecting D. oxycoccana populations in rabbiteye and southern highbush blueberry plantings. Emergence techniques detected significantly more D. oxycoccana adults from floral buds compared with sticky boards or bud dissection sampling methods. Emergence and dissection methods were not significantly different in detecting D. oxycoccana in either floral buds or leaf buds. Overall, the only sampling technique that was capable of detecting D. oxycoccana eggs was bud dissection. | |
