Global InformationCallosobruchus chinensis information
Callosobruchus chinensis, also known as the adzuki bean weevil, pulse beetle, Chinese bruchid or cowpea bruchid,[1] is a common species of beetle found in the bean weevil subfamily. 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.
C. chinensis is originally distributed in the tropics and subtropics of Asia. The first recorded sighting and description of C. chinensis was in China, where the species gets its name.[2] They are now spread worldwide due to the international trade of legumes.
C. chinensis is known to be a pest to many stored legumes,[3] including green gram, lentil, cowpea, pigeon pea, chickpea and split pea. The majority of their lifespan is spent on the host plant, such as growth, feed and reproduction. The penetration throughout the legume can lead to severe damage to the plant quality and thus cause huge economic loss. C. chinensis is one of the most damaging crop pests to the stored legume industry due to their generalized legume diets and wide distribution.[4]
This species has a very similar lifestyle and habitat to Callosobruchus maculatus and their identities are often mistaken for each other.[5] It also exhibits reproductive interference with C. maculatus. These beetles can be monandrous or polyandrous, depending on their environment.
