Amylase activities began earlier (2 hours) in soybean and 4-5 hours later in cowpea hence soybean would respond faster to distortion (e.g. insect infestations) than cowpea. Moreso mean values of amylase activities for cowpea were scattered and not well defined. Reducing sugars in cowpea could be distorted earlier (Day 1) while that of soybean took up to Day 3 indicating that soybean is more stable than cowpea. These two factors may have contributed to making soybean more resistant to insect attack compared to cowpea.enSoybean, cowpea, reducing sugars, amylase, storage pests.Article
