Present study of development, sex ratio and determination of damage of Callosobruchus chinensis was conducted on eight legumes namely green mung (Vigna radiata), black bean (Vigna mungo), lentil (Lens culinaris), white gram (Cicer arietinum), black gram (Cicer arietinum), soyabean (Glycine max), pea (Pisum sativum) and Cowpea (Vigna unguiculata). Development of Callosobruchus chinensis on the test legumes revealed that maximum number of adults (139.0) emerged on green mung, followed by Cowpea (91), black gram (68), white gram (17) and pea (10). Zero development was found in black bean, lentil and soyabean. Damage by Callosobruchus chinensis to eight legumes was highest in green mung (79.59), followed by black gram (59.30), Cowpea (51.04), and white gram (29.98) and pea (1.70). No damage was recorded in black bean, lentil and soyabean. The pest was considered as minor pest in Pakistan, although, it has been reported as major pest from the sub-continent. Present study was an attempt to fix the barrier for the pest in the leguminous commodities.
