''Carpophilus'' is a genus of sap beetles. They are agricultural pests that cause feeding damage to a variety of fruits, grains and other food products worldwide. The genus contains a great number of species.
Description
Adult ''Carpophilus'' are oblong-shaped beetles roughly 3 mm in length and black, brown or mottled yellow in colour. The elytra are short, exposing the last two abdominal tergites. The antennae are clubbed. Larval ''Carpophilus'' are yellowish with a brown head and a pair of urogomphi (giving the appearance of a forked tail). They are about 5 mm long when fully grown.Life cycle
Adult ''Carpophilus'' are active in spring and summer. They can fly several kilometres in search of host fruit. When this is discovered, the females lay eggs in fruit on the tree (in the case of stone fruit) or in fallen fruit on the ground (in the case of citrus, apples and figs). They may also lay in stored products such as dried fruit. Larvae feed and grow within the fruit. When mature, larvae leave the fruit to pupate in the ground. Larvae that infest stored products also pupate in them. There are several generations a year. Development from egg to adult takes approximately one month in summer. It is temperature-dependent, taking about 12 days at warm temperatures (32.2 °C) and up to 42 days at cooler temperatures (18.3 °C). Humidity also affects the life cycle, with faster development (and also more eggs laid) at higher humidity. ''Carpophilus'' can overwinter in the mature larva, pupa or adult stages, and does so in fruit, stored products, soil or in cracks or under bark of trees.Pest status
