Cydia nigricana (Fabricius, 1794) - (pea moth)

The moth is a pest of peas in Europe. The larvae feed on the developing seeds of peas, causing significant yield and quality losses. In Germany, around 20% of organically grown peas have been rejected in the mid 2000s due to damage by the moth exceeding tolerable levels. The pods of various other legumes (vetches, clover, lentil) are also attacked. The development time for the egg and the 5 larval stages lasts around 5 weeks. The mature larva moves to the ground and spins a cocoon for hibernation just below the soil surface. It then pupates in the spring and emerges as adult during the flowering time of the pea crop. Oviposition takes place in early summer. Crop rotation is recommended and insecticides are used in conventional pea crops. Various alternative control methods including resistance and biological control are being explored.

The adult has a wingspan of around 15 mm. The forewings are olive to dark brown with some light stripes along the leading edge.
