摘要

Twelve genotypes of bitter gourd viz., six resistant (IC-213311, IC-256185, IC-248256, IC-248282, HK-127 and MC-58), four medium resistant (HK-112, HK-156, BL-237 and Jaunpuri), one susceptible [IC-44410] and one highly susceptible (IC-85619-A) to melon fruit fly, Bactrocera cucurbitae were included to study the different physico-chemical traits associated with resistance and their influence on pest multiplication. Per cent fruit infestation and larval density were significantly and positively correlated with fruit diameter and negatively correlated with fruit toughness. Ascorbic acid, nitrogen, protein, phosphorus, silica, tannin, flavanol, total phenol, total ash, potassium, reducing sugar, non-reducing sugar and total sugar were significantly and negatively correlated with fruit fly infestation (r=-0.85 to -0.98) and larval density/fruit (r=-0.85 to -0.96), while the moisture content was positively associated with fruit fly infestation (r=0.89) and larval density/fruit (r=0.89).
