Answer: There are a number of insect pests that can cause the damage you describe: Cutworms - These dull colored worms feed on the foliage at night and clip plants off at the soil. During the day they hide in the soil just below the soil surface. Pea Weevil - The adults are brownish with white, black and grayish markings. The white, small, larvae have brown heads and mouths. The adults feed on blossoms and lay eggs on the young pods. The larvae burrow into the seed. Loopers - are green with light stripes down their
sides. They hump up when crawling and feed on the foliage. Green Cloverworm - The larvae are green and have 3 pairs of legs in the middle of the body and have white stripes down their sides. They feed on the leaves and pods.
Without knowing which pest is ravaging your crop, it's difficult to make a recommendation for treatment. If you can catch the culprit in the act, and it is a worm-like critter, the botanical Bacillus thuringensis should control them. Be sure to read the label and apply according to label directions.
