Cheilomenes Sexmaculata Pupa
__NOTOC__ ''Cheilomenes'' is a genus of ladybirds (Coccinellidae). Like other members of their subfamily they are large typical ladybirds. They are always shiny and often have bright spots on the elytra. The common African species ''C. lunata'' is an important predator of the citrus aphid, '' Toxoptera'', and wheat aphid, while ''C. vicina'' has been suggested as a biological control agent for the cowpea aphid. Both the larvae and adults are predatory. Freshly emerged larvae consume unhatched eggs, and eventually have a dappled appearance and 6 tubercles on each abdominal segment. Vulnerable stages in the life of ''C. sexmaculata'', including oviposition, hatching, moulting and pupation have been shown to occur after dark, probably as an adaptation to avoid exposure to natural enemies.

Chimoio
Chimoio is the capital of Manica Province in Mozambique. It is the fifth-largest city in Mozambique. Chimoio's name under Portuguese administration was ''Vila Pery''. Vila Pery developed under Portuguese rule as an important agricultural and textiles centre. The town lies on the railway line from Beira to Bulawayo, near the Cabeça do Velho rock. Located about 95 km from the Zimbabwean border, it has been a major destination for Zimbabwean immigrants looking for employment in Mozambique. History and landmarks Pre-colonial era The city of Chimoio, capital of Manica Province, lies on the Beira Corridor at an altitude of 750 metres, linking the coast and the interior of the continent. The name Chimoio comes from one of the sons of Ganda, paramount chief of the totemic Moyo clan, who came from M´bire and settled in those lands. Oral history says Chimoio, who was a great hunter, once killed an elephant in the lands of another clan. Chaurumba, their chief, judged Chimoio's be ...

Oman
Oman ( ; ar, عُمَان ' ), officially the Sultanate of Oman ( ar, سلْطنةُ عُمان ), is an Arabian country located in southwestern Asia. It is situated on the southeastern coast of the Arabian Peninsula, and spans the mouth of the Persian Gulf. Oman shares land borders with Saudi Arabia, the United Arab Emirates, and Yemen, while sharing Maritime boundary, maritime borders with Iran and Pakistan. The coast is formed by the Arabian Sea on the southeast, and the Gulf of Oman on the northeast. The Madha and Musandam Governorate, Musandam exclaves are surrounded by the United Arab Emirates on their land borders, with the Strait of Hormuz (which it shares with Iran) and the Gulf of Oman forming Musandam's coastal boundaries. Muscat is the nation's capital and largest city.

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] |
Russian Wheat Aphid
The Russian wheat aphid (''Diuraphis noxia'') is an aphid that can cause significant losses in cereal crops. The species was introduced to the United States in 1986 and is considered an invasive species there. This aphid is pale green and up to 2 mm long. Cornicles are very short, rounded, and appear to be lacking. There is an appendage above the cauda giving the aphid the appearance of having two tails. The saliva of this aphid is toxic to the plant and causes whitish striping on cereal leaves. Feeding by this aphid will also cause the flag leaf to turn white and curl around the head causing incomplete head emergence. Its host plants are cereal grain crops including wheat and barley and to a lesser extent, wild grasses such as wheatgrasses, brome-grasses, ryegrasses and anything in the grass family. The Russian wheat aphid is native to southwestern parts of Asia. It was introduced to many countries in Europe and Africa. It was first found in the U.S. in 1986 in Texas. The ...

Toxoptera Citricida
''Toxoptera citricida'' ( syn. ''Toxoptera citricidus'') is a species of aphid known by the common names brown citrus aphid, black citrus aphid, and oriental citrus aphid. It is a pest of citrus and vector for the pathogenic plant virus citrus tristeza virus. The aphid spread the virus through citrus groves in Brazil and Venezuela in the 1970s, leading to the near destruction of the citrus industry there. This aphid was first discovered in Florida in 1995. The adult aphid is shiny black and wingless (aptera) or winged (alate or alatoid), and the nymph is dark reddish brown. The aphid feeds on new buds and leaves. The virus is transmitted when the aphid introduces it into the phloem Phloem (, ) is the living biological tissue, tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as ''photosynthates'', in particular the sugar sucrose, to the rest of the plant.

Elytron
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), o ...

Ladybird
Coccinellidae () is a widespread family of small beetles ranging in size from . They are commonly known as ladybugs in North America and ladybirds in Great Britain. Some entomologists prefer the names ladybird beetles or lady beetles as they are not true bugs. Many of the species have conspicuous aposematic colours and patterns, such as red with black spots, that warn potential predators that they are distasteful. The majority of the more than 6,000 described species are generally considered beneficial insects, because many prey on herbivorous hemipterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies, ensuring their larvae have an immediate food source. However, some species such as the herbivorous Mexican bean beetle are agricultural pests. Etymology The name ''coccinellids'', created by Pierre André Latreille, is derived from the Latin word ''coccineus'' meaning "scarlet". The na ...
