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 2 and 4 centimetres (1 and 1 + 1 ⁄ 2 inches) long, and vary from a rusty red colour to almost entirely black; many colour variants exist and have led to considerable confusion with other ...
Palmetto weevil grubs infesting a Bismarck palm. The palmetto weevil (Rhynchophorus cruentatus) is an insect native to Florida, but has been found as far as southern Texas to the west and South Carolina to the north. [1] [2] It is the largest weevil in North America and the only kind of palm weevil in the continental United States. [1]
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 2 and 4 centimetres (1 and 1 + 1 ⁄ 2 inches) long, and are usually a rusty red colour—but many colour variants exist and have often been classified as different species (e.g., R. vulneratus).
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. [3] Two species are invasive pests outside ...
The South American palm weevil, Rhynchophorus palmarum, is a species of snout beetle. The adults are relatively large black beetles of approximately one and a half inch in length, and the larvae may grow to two inches in length.
These large beetles are considered a major pest in palm plantations, mainly in Cocos nucifera, Metroxylon sagu and Metroxylon solomonense. In fact the adults lay eggs in wounds in the stems of palms. After hatching, the weevil larvae excavate tunnels in the trunk and feed on the tissues, frequently leading to the death the host plants.
Diocalandra frumenti, commonly known as the palm weevil borer, the lesser coconut weevil, [3] or four-spotted coconut weevil, [4] is a species of weevil in the family Curculionidae. It occurs in Africa, Southern Asia and Northern Australia, and is a pest of coconut and other palm trees.
The life cycle of the African Palm Weevil is similar to that of other Rhynchophorus species. The adults lay eggs in wounds in the stems of dying or damaged parts of palms. After hatching, the weevil larvae excavate tunnels in the trunk and feed on the shoot and young leaves, frequently leading to the death the host plants.
