Pseudotheraptus Wayi
''Pseudotheraptus wayi'', the coconut bug, is a species of leaf-footed bug in the family Coreidae. It is a pest of coconut in East Africa. Distribution ''P. wayi'' is found in tropical and subtropical Africa, its range including Côte d'Ivoire, Kenya, Tanzania, Zanzibar, Zambia, Botswana and South Africa. Life cycle Eggs are laid on host plants and take 30 to 40 days to develop, depending on external conditions. As a true bug, this species goes through incomplete metamorphosis, the nymph passing through five instar stages. The adult females survive for up to two months, laying two or three eggs a day. Host range ''P. wayi'' is a pest of coconut and various other fruit crops. It attacks the growing points of shoots, flowers (where it may cause petal drop) and fruit (where it may cause abnormal shape, pitting, brown or black lesions, exudation of gum and fruit drop). In coconuts, young nymphs feed at the base of male flowers, and older nymphs and adults feed on the female flowers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pecan
The pecan (''Carya illinoinensis'') is a species of hickory native to the southern United States and northern Mexico in the region of the Mississippi River. The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, Texas, and Mexico, which produces nearly half of the world total. The seed is an edible nut used as a snack and in various recipes, such as praline candy and pecan pie. The pecan is the state nut of Alabama, Arkansas, California, and Texas and is also the state tree of Texas. Name "Pecan" is from an Algonquin word, variously referring to pecans, walnuts, and hickory nuts. There are many pronunciations, some regional and others not.See "Pecan" at Wiktionary. The most common American pronunciation is . There is little agreement in the United States regarding the "correct" pronunciation, even regionally.

Hemiptera Of Africa
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles.

Green Bean
Green beans are young, unripe fruits of various cultivars of the common bean ('' Phaseolus vulgaris''), although immature or young pods of the runner bean (''Phaseolus coccineus''), yardlong bean ( ''Vigna unguiculata'' subsp. ''sesquipedalis''), and hyacinth bean (''Lablab purpureus'') are used in a similar way. Green beans are known by many common names, including French beans (), string beans (although most modern varieties are "stringless"), and snap beans or simply "snaps". In the Philippines, they are also known as "Baguio beans" or "" to distinguish them from yardlong beans. They are distinguished from the many other varieties of beans in that green beans are harvested and consumed with their enclosing pods, before the bean seeds inside have fully matured. An analogous practice is the harvest and consumption of unripened pea pods, as is done with snow peas or sugar snap peas. Culinary use As common food in many countries, green beans are sold fresh, canned, and f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oecophylla Longinoda
''Oecophylla longinoda'' (common name weaver ant) is a species of arboreal ant found in the forested regions of tropical Africa. They are one of only two extant species of the genus ''Oecophylla'', the other being ''O. smaragdina''. They make nests in trees made of leaves stitched together using the silk produced by their larvae. Description The worker is a fairly large ant with a length of . The antennae have twelve segments, the first segment exceeding in length the second and third combined. The clypeus, at the front of the head, is large and convex and overhangs the outer edge of the mouthparts. The large mandibles have long triangular teeth which cross over one another when the ant is at rest. This ant ranges in colour from orangeish-brown to dark brown; the thorax is clad in fine pubescence while the abdomen is covered with short erect hairs. The tip of the abdomen has glands that produce pheromones. The feet have suction pads which enables these ants to cling to surface ...

Anoplolepis Custodiens
''Anoplolepis custodiens'', commonly known as the common pugnacious ant, is a species of ant in the genus ''Anoplolepis'', native to central and southern Africa. Individual ants may come in a range of colors and sizes. Found in dry and cultivated areas, it is an important source of prey for some pangolins and aardvarks. Although generally aggressive, ants from other colonies of ''Anoplolepis custodiens'' are not attacked. Description The worker common pugnacious ant varies greatly in size and is up to long, and polymorphic, being yellowish-brown, reddish-brown or darker chocolate-brown, often with the abdomen darker than the rest of the ant. Darker individuals can be distinguished from the black pugnacious ant (''Anoplolepis steingroeveri'') by the chequer-board dark pattern on the gaster, which is caused by reflection of light by pubescent hairs which lie in different directions on the two sides. Distribution and habitat This ant is native to tropical sub-Saharan Africa. Its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Mango
A mango is an edible stone fruit produced by the tropical tree ''Mangifera indica''. It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. ''M. indica'' has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus ''Mangifera'' also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion. Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh. Etymology The English word ''mango'' (plural "mangoes" or "mangos") originated in the 16th century from the Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
