''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 in 1758 which is where the beetle gets its species name. ==Habitat and distribution== ''C. chinensis'' displays a Cosmopolitan distribution pattern and has been spotted in most countries due to the commercial export of beans.〔 The beetle's natural ranges are in the tropics and subtropics of Asia, and their population has grown extensively since the cultivation and distribution of legumes. Their distribution is heavily influenced by human production and they only live by legumes that are suitable for them to mate on and their larvae to feed on. Both the larvae and the adults feed on the legume. Some of their common host plants include Green Gram, lentil, Cowpea, pigeon pea, chickpea and other pea species though they are known to live on many more legume hosts. The species' most preferred habitat is in the tropics, on green gram or chickpeas. They reach the height of egg production and legume infestation in July–August.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Callosobruchus chinensis」の詳細全文を読む スポンサード リンク
