Biology: Overwinter as adults and move to fruit trees when other food (field crops or weeds) is not as abundant. Feed with piercing-sucking mouthparts.
Symptoms: Deep pits in fruit; water-soaked gumming on peach fruit; brown spots in tissue of apples.
Monitoring: Use sweep nets in weedy areas or orchard borders; inspect fruit for damage.
Treatment Threshold: No threshold determined.
Degree Day Model: None
Management Considerations: Early-season feeding causes fruit distortion. Injury near harvest causes pits and sunken areas on fruits and lowers fruit quality and storability.
