ABSTRACT

The members of the genus Callosobruchus, in particular, feed on stored beans. The species Callosobruchus phaseoli is distributed in Brazil, the United States of America, Nigeria, Colombia, Mexico, the Philippines and India. In India, this species was previously recorded from Coimbatore (Tamil Nadu) and in present investigation from Kanthewadi, Kembali, Gargoti and Haladi from district Kolhapur, Maharashtra (present investigation) on seeds of Lima bean (Phaseolus lunatus). Key characters of C. phaseoli are: Reddish brown and pubescent body; the pronotum is yellow with dark brown stripes and a white basal lobe; the elytra are mostly yellow with elongate white patches in the coastal area and variable black stripes at the lateral and apical parts. Pygidium swollen at the apex and the meta-femur with a distinct tooth-like angulation at its posterior end. The present study describes the taxonomy of C. phaseoli along with genitalia for the first time with color photographs.
