Exploration of arthropod fauna on linseed and management of bud fly and capsule borer

Abstract

Linseed (Linum usitatissimum L.), commonly known as flax, is one of the oldest cultivated oilseed crops. It is grown on approximately 1.95 lakh hectares in India and offers numerous benefits. Linseed is valuable in human diets, provides raw materials for industries such as paints and textiles, and serves as cattle feed. A portion of its oil is consumed by humans, as it contains all eight essential amino acids and is a rich source of omega-3 and omega-6 fatty acids (linolenic acid). Despite its benefits, linseed cultivation faces challenges from various insect pests and diseases at different growth stages, which severely impact its yield and quality. Among these biotic stresses, the bud fly (Dasyneura lini) is the most destructive pest, causing up to 80% seed yield loss. Limited research on linseed pest management has been conducted in southern Bihar. Therefore, this study aimed to identify major natural enemies of linseed pests and develop effective management strategies for bud fly and capsule borer under changing climatic conditions to minimize yield losses. newline
