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

Abstract<italic>Callosobruchus maculatus</italic> 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 <italic>C. maculatus</italic> biology. Four different sets of temperature and humidity exhibited a different influence on the development of <italic>C. maculatus</italic> both in natural and artificial diet patterns. The present data revealed that the population of <italic>C. maculatus</italic> was surviving better at 27.5 − 32.5 °C and 80–90%. The artificial diet based on vicilin and chitinases suppressed <italic>C. maculatus</italic>, as evidenced by delayed developmental times and reduced adult longevity (AL). [ABSTRACT FROM AUTHOR]
