Rhynchophorus Phoenicis
The African Palm Weevil or ''Rhynchophorus phoenicis'' is a species of beetles belonging to the family Curculionidae. Varieties * ''Rhynchophorus phoenicis'' var. ''niger'' Faust, 1899 * ''Rhynchophorus phoenicis'' var. ''ruber'' Faust, 1899 Description ''African Palm Beetles'' can reach a body length of about 25 mm. These large beetles are considered a serious pest in palm plantations, particularly damaging young palms, mainly ''Cocos nucifera'', ''Metroxylon sagu'', Raphia species, ''Elaeis guineensis'' and ''Phoenix dactylifera''. 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. The larvae of this palm weevil are edible. Distribution The species is widespread throughout tropical and equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. 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 classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Curculionidae
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae. They include the bark beetles as the subfamily Scolytinae, which are modified in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae. Description Adult Curculionidae can be recognised by the well-developed, downwards-curved snout (rostrum) possessed by many species, though the rostrum is sometimes short (e.g. Entiminae). They have elbowed antennae that end in clubs, and the first antennal segment often fits into a groove in the side of the rostrum. The body tends to be robus ...

Cocos Nucifera
The coconut tree (''Cocos nucifera'') is a member of the palm tree family (Arecaceae) and the only living species of the genus ''Cocos''. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a Nut (fruit), nut. The name comes from the old Portuguese people, Portuguese word ''Coco (folklore), coco'', meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are ubiquitous in coastal tropical regions and are a cultural icon of the tropics. The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, form a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called ''coconut water'' ...

Metroxylon Sagu
''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. Description True sago palm is a suckering (multiple-stemmed) palm, each stem only flowering once (hapaxanthic) with a large upright terminal inflorescence. A stem grows tall before it ends in an inflorescence. Before flowering, a stem bears about 20 pinnate leaves up to long. Each leaf has about 150–180 leaflets up to long. The inflorescence, tall and wide, consists of the continuation of the stem and 15–30 upwardly-curving (first-order) branches spirally arranged on it. Each first-order branch has 15–25 rigid, distichously arranged second-order branches; each second-order branch has 10–12 rigid, distichously arranged third-order branches. Flower pairs are spirally arranged on the third-order branches, each pair consisting of one male and one hermaphrodite flower. The fruit is drupe-like, about ...

Raphia (palm)
Raffia palms (''Raphia'') are a genus of about twenty species of palms native to tropical regions of Africa, and especially Madagascar, with one species (''R. taedigera'') also occurring in Central and South America. ''R. taedigera'' is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods". They grow up to tall and are remarkable for their compound pinnate leaves, the longest in the plant kingdom; leaves of ''R. regalis'' up to long and wide are known. The plants are monocarpic, meaning that they flower once and then die after the seeds are mature. Some species have individual stems which die after fruiting, but have a root system which remains alive and sends up new stems which fruit. Cultivation and uses Fiber Raffia fiber is produced from the membrane on the underside of the leaf fronds. The membrane is taken off to create a long thin fiber, which can be rolled together for added ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elaeis Guineensis
''Elaeis guineensis'' is a species of palm commonly just called oil palm but also sometimes African oil palm or macaw-fat. It is the principal source of palm oil. It is native to west and southwest Africa, specifically the area between Angola and the Gambia; the species name, ''guineensis'', refers to the name for the area, Guinea, and not the modern country now bearing that name. The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, Cambodia, the West Indies, and several islands in the Indian and Pacific Oceans. The closely related American oil palm ''Elaeis oleifera'' and a more distantly related palm, ''Attalea maripa'', are also used to produce palm oil. ''E. guineensis'' was domesticated in West Africa along the south-facing Atlantic coast. There is insufficient documentation and insufficient research to make any guesses as to when this occurred. Human use of oil palms may date as far back as 5,000 years in Egypt; in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenix Dactylifera
''Phoenix dactylifera'', commonly known as date or date palm, is a flowering plant species in the palm family, Arecaceae, cultivated for its edible sweet fruit called dates. The species is widely cultivated across northern Africa, the Middle East, and South Asia, and is naturalized in many tropical and subtropical regions worldwide. ''P. dactylifera'' is the type species of genus ''Phoenix (plant), Phoenix'', which contains 12–19 species of wild date palms. Date trees reach up to in height, growing singly or forming a clump with several stems from a single root system. Slow-growing, they can reach over 100 years of age when maintained properly. Date fruits (dates) are oval-cylindrical, long, and about in diameter, with colour ranging from dark brown to bright red or yellow, depending on variety. Containing 61–68 percent sugar by mass when dried, dates are very sweet and are enjoyed as desserts on their own or within confectionery, confections. Dates have been cultiv ...

Beetles Of Africa
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. 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 life-forms; 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 (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
