(Callosobruchus chinensis)

Description

Callosobruchus chinensis is a common species of beetle found in the bean weevil subfamily, and is known to be a pest to many stored legumes. Although it is commonly known as the adzuki bean weevil it is in fact not a true weevil, belonging instead to the leaf beetle family, Chrysomelidae. Other common names include the pulse beetle, Chinese bruchid and cowpea bruchid. This species has a very similar lifestyle and habitat to Callosobruchus maculatus and their identities are often mistaken for each other. This beetle is a common pest targeting many different species of stored legumes and it is distributed across the tropical and subtropical regions of the world. C. chinensis is one of the most damaging crop pests to the stored legume industry due to their generalized legume diets and wide distribution. The first recorded sighting and description of C. chinensis was in China which is where the beetle gets its species name.
