Aphthona whitfieldi Bryant (Coleoptera: Chrysomelidae) is a major insect pest of Jatropha curcas L. (Euphorbiacae) in Burkina Faso and other countries in West Africa. The insect pest feeds on the roots and the leaves of the plant. When the attacks are heavy, the plant may lose all its leaves and die off. Unfortunately, little information is available on the biology of this insect pest. A study was conducted on the biology of this insect pest in the Sissili province, South Burkina Faso and resulted in the knowledge of some of the biological features of the insect pest. Aphthona whitfieldi was reared from 13th July to 22th October 2015. Larvae and pupae were collected in J. curcas plantations near Leo, the capital city of the Sissili province, and brought to the laboratory for rearing. The insects were observed daily and the dimensions and the duration of each stage were recorded. We recorded two larval stages (1st and 3rd): a pre-pupa and a pupal stage. The pupa was free and white milk-like. Both the pre-pupa and the pupal stages lasted for five days. The 1st instar larva was smaller than the third one.
