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 ...
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).
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.
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 .

[MP 4] By the time one observes symptoms, the palm is usually already dead. Weevils are infected while feeding as adults or larvae, but only female weevils carry a large internal infestation around their oviducts and are capable of transmitting the nematode during oviposition. [6] Females are capable of laying as many as 693 eggs. [5]
During all stages of life, this species is red, with adult females often showing black patches on their backs after feeding. Red palm mite egg. Red palm mite eggs are 0.12 mm long and 0.09 wide. The eggs are smooth and can be found in groups attached to the underside of leaves. [2] Larvae are 0.18–.020 mm in length and only have three pairs ...
Small business owners should not forget about a rule — currently in legal limbo — that would require them to register with an agency called the Financial Crimes Enforcement Network, or FinCEN ...
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.
