Divergence in the Morphology and Energy Metabolism of Adult Polyphenism in the Cowpea Beetle <i>Callosobruchus maculatus</i>.

ABSTRACT: Adult polyphenism is a prevalent form of adaptive evolution that enables insects to generate discrete phenotypes based on environmental factors. However, the morphology and molecular mechanisms underlying adult dimorphism in Callosobruchus maculatus (a global storage pest) remain elusive. Understanding these mechanisms is crucial for predicting the dispersal and population dynamics of C. maculatus. This knowledge can also provide a theoretical basis for biological control strategies. In this study, we compared the morphology of the hind wing and chest muscles, the transcriptional profiles, the energy metabolism substances, and the fecundity between the flight form and the normal form. The flight form displays a lighter overall appearance with small black spots, while the norm
