Field Identification
A small tortricid whose caterpillars live inside pea pods, eating seeds and leaving frass that ruins shelling day. You notice the moth never—you find the crime at the kitchen bowl.
Single creamy larva per pod usually; tiny entry hole near calyx or suture. Flight peaks tie to degree-days; pheromone traps catch males for timing, not mass murder.
How to Deal With It
Organic Control Methods
Bt kurstaki or spinosad during egg hatch—must contact fresh pods; repeat after rain; evening sprays spare some daytime flyers.
Trichogramma releases target eggs in research and specialty fields; generalist parasitoids help at margins—preserve flowering strips.
Early-maturing cultivars escape late flights; destroy crop residues; wide rotation away from Vicia/Pisum neighbors.
Floating row cover until flowering—remove for pollination if needed, then accept some loss or hand-pollinate tunnels.
Trap thresholds vary by region—learn your local biofix instead of guessing from a meme chart.
