Comparison of Oriental fruit moth trap catches 2010 and 2011
After weeks of no activity, Oriental fruit moth adult emergence has begun.
Oriental fruit moth is a direct pest of pome and stone fruit crops. The cool spring has delayed spring adult emergence, but high trap catch numbers in the last week indicate that egg laying will begin this week. This is in dramatic contrast to 2010 when degree days were accumulating two weeks ahead of normal. If using insecticides for control of Oriental fruit moth, pink and petal fall stages are timings available for treatment sprays. If using mating disruption, then pheromone dispensers should already be in the orchard.
