Impact of diets and environmental variables on the biology of Callosobruchus maculatus (F). (Coleoptera: Chrysomelidae)

Callosobruchus maculatus is a global and widely distributed grain pest. Chemical control has potential toxicity risks, and the present study aimed to estimate the repercussions of environmental variations and diet effects on C. maculatus biology. Four different sets of temperature and humidity exhibited a different influence on the development of C. maculatus both in natural and artificial diet patterns. The present data revealed that the population of C. maculatus was surviving better at 27.5 − 32.5 °C and 80–90%. The artificial diet based on vicilin and chitinases suppressed C. maculatus, as evidenced by delayed developmental times and reduced adult longevity (AL).
