| Western cherry fruit fly expected to emerge Sunday The Union County Cherry Fruit Fly Inspector Greg Franklin has announced that emergence of the first adult Western cherry fruit flies will start Sunday in the La Grande area. Unmanaged fruit trees do not make good shade trees because they harbor a multitude of insect and disease pests. Those who choose to spray their own trees are reminded to be certain the product they use is for fruit/cherry trees. lt is recommended to remove any cherry trees not used for fruit production and replace with a suitable shade tree. OR Remove all blossoms or fruit from trees prior to cherry fruit fly emergence. OR Cut trees down. Franklin will cut unwanted cherry trees down at no cost. Western Cherry Fruit Fly Biology Notes: Cherry fruit flies spend about 10 months out of the year as pupae in the soil. Presently, Ridley Pest Control (541-910-7378) is the only known commercial pesticide operator (CPO) in Union county available for cherry fruit fly control. Tree height and canopy influence effectiveness of sprays. Eggs hatch within seven to 70 days then larvae feed in the fruit for two to three weeks. Other licensed CPOs (through the Oregon Department of Agriculture) are encouraged to contact the Union County OSU Extension office to be included on the service provider list. Call Franklin at 541-663-3345. However, the wood will be left on site. Management options for the Western cherry fruit fly include: Spray your own trees with registered insecticide products. Adults begin laying eggs in fruit seven days after emergence. Larvae then emerge from the fruit, drop to the ground and pupate in the soil and overwinter until this time next year. |
