文摘

It was studied the tolerance of five spring pea cultivars to Bruchus pisorum based on the weevil damage and chemical composition of seeds related to pea weevil tolerance. From visibly damaged pea seeds by pea weevil was isolated the parasitoid Triaspis thoracica Curtis (Hymenoptera, Braconidae). Cultivars with a lower protein and phosphorus content had a lower level of damage. The crude protein, crude fiber and phosphorus content in damaged seeds significantly or no significantly was increased. Modus, followed Glyans had emerged as tolerant cultivars against the pea weevil. They had the lowest total damaged seed degree, loss in weight of damaged seeds, values of harmfulness coefficient and lower protein and phosphorus content.KeywordsBruchus pisorumpea cultivarsdamaged seedscrude proteincrude fiberphosphorus
