Early Pest Detections - Codling Moth & Peach Twig Borer

Codling Moth & Peach Twig Borer

Pest Alert: Early Detection of Codling Moth & Peach Twig Borer

Location: Farmway & Karcher area, Treasure Valley, Idaho
Date: March 24, 2026

Backyard growers in the Farmway and Karcher area have reported early captures of key orchard pests in delta traps:

• Codling moth (Cydia pomonella) – 1 adult captured
• Peach twig borer (Anarsia lineatella) – 1 adult captured

These detections are earlier than typically expected, signaling that pest activity has begun in localized areas.

What This Means

• This may represent early flight initiation (biofix approaching or beginning) for both pests.
• Even low trap counts are important—they indicate the start of adult emergence.
• Warmer early-season conditions may be accelerating development.

Recommended Actions for Growers

• Deploy traps immediately if not already in place (especially in apples, pears, peaches, nectarines).
• Check traps regularly (2–3 times per week) to monitor trends.
• Record first consistent captures to establish a reliable biofix.
• Begin tracking Growing Degree Days (GDD) for precise timing of:
  • Egg hatch (Codling moth)
  • Larval emergence (Peach twig borer)Why It Matters

Why It Matters

Accurate timing based on trap data + GDD allows for:

• Improved spray timing
• Reduced unnecessary pesticide applications
• Better pest control and fruit protection
