Effects of secondary plant metabolites (caffeine and theophylline on reproduction of lepidopteran species were studied using Bombyx mori, Spodoptera litura, Danaus chrysippus and Catopsilia crocale… Expand
Changes in developmental rates and biomass energy in Callosobruchus maculatus (F.) (Coleoptera Bruchidae) reared on different foods and temperatures
Abstract The developmental rates and corresponding changes in the biomass of life stages of Callosabruchus maculatus were studied as functions of food type and temperature. The growth rate of C.… Expand
