In Switzerland, ten years after the introduction of dry harvested field peas for animal feed, C. nigricana has become a serious pest. The hatching of the moth starts at 150 day-degrees above 10 degrees C (accumulated from the beginning of the year). The flight is observed from mid-May until the beginning of July when temperatures are higher than 18 degrees C. About one half of the seeds in a pod are damaged by one larva.
