In: Journal of Economic EntomologySummary: Ensayos de campo en 3 cultivos mostraron que la alimentacion de los gusanos de la semilla, Hylemya platura (Meigen) e H. florilega (Zetterstedt), fue mas nociva en plantulas de frijol tipo lima var. Fordhook 212. Las plantulas sobrevivientes de habichuela var. Tendercrop y de frijol var. California Light Red Kidney tuvieron aproximadamente el mismo grado de dano. Cuando las plantas de los 3 cultivares de habichuela estaban ligeramente danadas por los gusanos de la semilla (0-25 por ciento de perdida del primer par de hojas unifoliadas), hubo una reduccion significativa del rendimiento (11-18 por ciento). La reduccion en el rendimiento del frijol lima Fordhook y California Light Red Kidney, se observo solamente en plantulas que tenian 75 por ciento de dano en el primer par de hojas unifoliadas. (RA-CIAT)Summary: 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 french beans and California Light Red Kidney dry beans had aprox. the same degree of injury. When seedlings from 3 french bean cultivars were slightly damaged by seed maggots (0-25 percent loss of the 1st pair of unifoliate leaves), there was a significant yield loss(11-18 percent). Yield reduction in Fordhook lima beans and California Light Red Kidney dry beans was observed only in seedlings that had more than 75 percent loss of the 1st pair of unifoliate leaves. (AS)
