Rhynchophorus Distinctus
''Rhynchophorus'', or common name palm weevils, is a genus of beetles in the weevil family, Curculionidae. Palm weevils are major pests of various trees in the family Arecaceae throughout the tropics including: coconut (''Cocos nucifera''), ''Areca catechu'', species of the genus ''Phoenix'', and ''Metroxylon sagu''. Two species are invasive pests outside their native ranges, ''Rhynchophorus ferrugineus'' and ''Rhynchophorus palmarum The South American palm weevil, ''Rhynchophorus palmarum'', is a species of snout beetle.

Rhynchophorus Ferrugineus
The palm weevil ''Rhynchophorus ferrugineus'' is one of two species of snout beetle known as the red palm weevil, Asian palm weevil or sago palm weevil. The adult beetles are relatively large, ranging between long, and are usually a rusty red colour—but many colour variants exist and have often been classified as different species (e.g., '' Rhynchophorus vulneratus''). Weevil larvae can excavate holes in the trunks of palm trees up to long, thereby weakening and eventually killing the host plant. As a result, the weevil is considered a major pest in palm plantations, including the coconut palm, date palm and oil palm. Originally from tropical Asia, the red palm weevil has spread to Africa and Europe, reaching the Mediterranean in the 1980s. It was first recorded in Spain in 1994, and in France in 2006. Additional infestations have been located in Malta, Italy (Tuscany, Sicily, Campania, Sardinia, Lazio, Marche, Puglia and Liguria), Croatia and Montenegro. It is also well esta ...

He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect Biological classification, classification.

Rhynchophorus Vulneratus
The palm weevil ''Rhynchophorus vulneratus'' is one of two species of snout beetle known as the red palm weevil, Asian palm weevil, or Sago palm weevil. The adult beetles are relatively large, ranging between long, and vary from a rusty red colour to almost entirely black; many colour variants exist and have led to considerable confusion with other species (e.g., '' Rhynchophorus ferrugineus''). Weevil larvae of these species can excavate holes in the trunk of a palm tree up to long, thereby weakening and eventually killing the host plant. As a result, these weevils are considered major pests in palm plantations, including the coconut palm, date palm and oil palm. Distribution The native range of this species is considered to include Indonesia, Malaysia, Myanmar, Singapore, and Thailand; outside its native range it has been reported and confirmed only from the United States. Originally from tropical Asia, this palm weevil (initially misidentified as the closely relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
