Rhynchophorus bilineatus, common name Black Palm Weevil, is a species of beetles belonging to the family Curculionidae.
Rhynchophorus bilineatus can reach a body length of about 40mm. 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.
This species can be found in the Moluccas, Papua New Guinea and Solomon Islands. Reports of Rhynchophorus ferrugineus from these areas are likely to be misidentified specimens of bilineatus.
The larval grub is considered a delicacy in West Papua, as well in Papua New Guinea. [1] The Asmat, Korowai and Kombai peoples of southern New Guinea also hold the larva in high regard as a food source. [2] Sago larvae are roasted on a spit to celebrate special occasions in New Guinea. [3]
Beetles are insects that form the order Coleoptera, in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Some others also have unique characteristics, such as the common eastern firefly, which uses a light-emitting organ for mating and communication purposes
The Arecaceae is a family of perennial, flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem, except for the Hyphaene genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.
Sago is a starch extracted from the pith, or spongy core tissue, of various tropical palm stems, especially those of Metroxylon sagu. It is a major staple food for the lowland peoples of New Guinea and the Maluku Islands, where it is called saksak, rabia and sagu. The largest supply of sago comes from Southeast Asia, particularly Indonesia and Malaysia. Large quantities of sago are sent to Europe and North America for cooking purposes. It is traditionally cooked and eaten in various forms, such as rolled into balls, mixed with boiling water to form a glue-like paste (papeda), or as a pancake.
A woodworm is the wood-eating larva of many species of beetle. It is also a generic description given to the infestation of a wooden item by these larvae.
Entomophagy in humans or human entomophagy describes the consumption of insects (entomophagy) by humans in a cultural and biological context. The scientific term used in anthropology, cultural studies, biology and medicine is anthropo-entomophagy. Anthropo-entomophagy does not include the eating of arthropods other than insects such as arachnids and myriapods, which is defined as arachnophagy.
Washingtonia filifera, the desert fan palm, California fan palm, or California palm, is a flowering plant in the palm family Arecaceae, native to the far southwestern United States and Baja California, Mexico. Growing to 15–20 m (49–66 ft) tall by 3–6 m (10–20 ft) broad, it is an evergreen monocot with a tree-like growth habit. It has a sturdy, columnar trunk and waxy, fan-shaped (palmate) leaves.
The Kombai are a Papuan people living in the Indonesian province of South Papua, more specifically in Mappi Regency. Their total population is about 5,650.
Brentidae, sometimes known as the primitive weevils, is a cosmopolitan family of primarily xylophagous beetles also known as straight-snouted weevils. The concept of this family has been expanded with the inclusion of three groups formerly placed in the Curculionidae; the subfamilies Apioninae, Cyladinae, and Nanophyinae, as well as the Ithycerinae, previously considered a separate family. They are most diverse in the tropics, but occur throughout the temperate regions of the world. They are among the families of weevils that have non-elbowed antennae, and tend to be elongate and flattened, though there are numerous exceptions.
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 long, and are usually a rusty red colour—but many colour variants exist and have often been classified as different species. Weevil larvae can excavate holes in the trunks of palm trees up to 1 metre (3.3 ft) 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.
For the other plant known as sago palm, see Cycas revoluta.
Metroxylon sagu, the true sago palm, is a species of palm in the genus Metroxylon, native to tropical southeastern Asia. The tree is a major source of sago starch.
The palmetto weevil is an insect native to Florida, but has been found as far as southern Texas to the west and South Carolina to the north. It is the largest weevil in North America and the only kind of palm weevil in the continental United States. It infests palms and is considered a pest. Its main target is the Canary Island date palm, but date palms, sabal palms, saw palmetto, Washingtonia, Pritchardia, royal palms, Latania, coconut palms, Caryota, and Bismarckia are also susceptible. Distressed palm trees are usually attacked, which makes transplanted trees a frequent target. The Palmetto Weevils mate at the base of the palm branches where the females deposit their eggs. The grubs then eat into the palm tree, killing it. After the larvae have turned into adult weevils, the damage can be seen, but by then, it is considered to be too late for the tree. The life cycle from egg to adult for a palmetto weevil is about 84 days. For prevention, it is recommended an appropriate insecticidal crown drench is done twice a year for high value palms.
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 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. Weevil larvae of these species can excavate holes in the trunk of a palm tree up to 1 metre 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.
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, 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. 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.
TheAfrican Palm Weevil or Rhynchophorus phoenicis is a species of beetles belonging to the family Curculionidae.
Diocalandra frumenti, commonly known as the palm weevil borer, the lesser coconut weevil, or four-spotted coconut weevil, 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.
A hugu is a sago-palm weevil in Papua New Guinea that has been used by men of the Onabasulu people as a musical instrument. The musicians pin the beetle onto a sharpened stick and hold the beetle up to their mouths, spinning the stick and beetle. If they do this during daylight, the beetle will beat its wings and provide a buzzing sound. The musicians' mouths act as a variable resonance chamber, in the same way as it does for a musician playing a Jew's harp or musical bow. By opening and closing their mouths and changing the shape, musicians can raise and lower the pitch, and make the music louder or softer.
Mojojoy is the name of larvae of different palm weevils found in the Amazon region of Colombia, eaten as food and are known as a pest for various palm species. In Peru, it is known as suri or cocotero. The flavor has had different descriptions including resembling the taste of hazelnut or butter. It is also considered a sustainable food source.
