Polytus mellerborgi, commonly known as small banana weevil, is a species of weevil widely distributed in southeastern Polynesia through Melanesia, Micronesia, Indo-Malaya, south China, Burma, India, Sri Lanka, other islands of the Indian Ocean to Madagascar and as far as Mexico and Central America.

Description

This small beetle is about 1.0 cm to 1.1 cm in length excluding the rostrum. [3] Due to the characteristic black color, the species can be misidentified as a diminutive form of Cosmopolites sordidus . [4] Antennae composed of eight antennomeres, a scape, pedicel and flagellum composed of six flagellomeres. The last flagellomere is the antennal club. Both flagellum and antennal club composed of most sensilla. According to research, there are five types of sensilla: sensilla trichodea, sensilla chaetica type 1 and 2, sensilla basiconica, and sensilla gemmiformia; and cuticular grooves found in the species. [5]

Biology

It is one of the most common pest that attack banana and plantains. Adults are found in numbers in decaying trunks and bores in the decaying corms and stalks of banana. [5] [6]

Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.

This species attacks both standing crops and stored cereal products, including wheat, rice, sorghum, oats, barley, rye, buckwheat, peas, and cottonseed. The maize weevil also infests other types of stored, processed cereal products such as pasta, cassava, and various coarse, milled grains. It has even been known to attack fruit while in storage, such as apples.
