We are currently in a lull of direct pest activity throughout the western apple region. Codling moth degree-day (DD) accumulations have reached about 800 and 1250 in Henderson and Cleveland/Lincoln Counties, respectively. First-generation adult emergence is essentially complete in orchards at elevations of ~2100 ft, and in lower elevations (<800 ft) second-generation adult emergence is predicted to begin in about a week.

Tufted apple bud moth cumulative DDs are about 1,000, so there is still time to make an insecticide application for this pest if one has not been made in the past couple of weeks.

Second generation oriental fruit moth flight is also nearing completion, with low trap captures in orchards we’ve been monitoring.
Curative applications of insecticides/miticides for control of aphids, leafhoppers, or European red mites is the main concern at this time. However, overall populations remain low in most orchards, so be sure to scout orchards for these pests to determine the need for an insecticide.
