Field tests on 3 crops showed that feeding of seed maggots. Hylemya Platura (Meigen) and H. florilega (Zetterstedt) , was most damaging to seedlings of 'Fordhook 242' lima beans. Surviving seedlings of 'Tendercrop' snap beans and 'California Light Red Kidney' dry beans had approximately the same degree of injury. When seedlings from 3 snap bean cultivars were slightly damaged by seed maggots (0–25% loss of the 1st pair of unifoliate leaves) , there was a significant yield loss (11–48%). Yield reduction in Fordhook lima beans and California Light Red Kidney dry beans was observed only in seedlings which had more than 75% loss of the 1st pair of unifoliate leaves.
