Apple Orchard Pests

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Apple Orchard Pests banner​​​​​​​

DATCP cooperators maintain pheromone traps in their orchards to monitor the seasonal activity of economically important apple pests. Data from insect traps is integral to orchard integrated pest management programs and contributes to reduced damage and pesticide use. In​sect​s currently monitored include apple maggot, codling moth, dogwood borer, lesser peachtree borer, redbanded leafroller, and obliquebanded leafroller. The results ​are presented below and will be updated weekly through August.​​
