Cheilomenes Sexmaculata
''Cheilomenes sexmaculata'' is a species of ladybird. Although sometimes known by the common name of six-spotted zigzag ladybird, this is misleading as there are several colour morphs and some colour morphs of the species can be confused with ''Micraspis discolor'' and ''Chilocorus nigrita''. The species has a wide distribution range within the Asian tropics and subtropical zones from India to Japan and parts of the Australian region. They have been introduced into the Caribbean islands as a biocontrol agent and their spread to South America was noted in 2019. It is well known as a predator of aphids and other small insects. Description This small beetle is about 3 to 4 mm in body length. Body color varies from yellow to canary yellow. Elytra black. Biology It is a voracious predator on several whiteflies and aphids such as ''Aphis gossypii'', '' Myzus persicae'', ''Aphis craccivora'', ''Amrasca'', ''Empoasca'' and '' Leptocentrus''. In addition to them, it feeds on a wide prey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Aphis Craccivora
''Aphis craccivora'', variously known as the cowpea aphid, groundnut aphid or black legume aphid, is a true bug in the family ''Aphididae''. Originally of probable Palearctic origin, it is now an invasive species of cosmopolitan distribution. Description ''Aphis craccivora'' is a small species of aphid. The female has a glossy black or dark brown body with a prominent cauda (tail-like protrusion), and legs in some shade of brown or yellow. The antennae have six segments and these and the limb segments, cauda and cornicles are pale proximally (close to the body) and dark distally (further from the body). The adults do not have wax on their dorsal surface but the nymphs are lightly dusted with wax. Winged females are up to long and have cross-barring on the abdomen. Wingless females are a little smaller. Distribution ''Aphis craccivora'' is believed to be Palearctic in origin but has expanded its range so that now it is near cosmopolitan. In recent years its range has extend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Diaspididae
Diaspididae is the largest family of scale insects with over 2650 described species in around 400 genera. As with all scale insects, the female produces a waxy protective scale beneath which it feeds on its host plant. Diaspidid scales are far more substantial than those of most other families, incorporating the exuviae from the first two nymphal instars and sometimes faecal matter and fragments of the host plant. These can be complex and extremely waterproof structures rather resembling a suit of armor. For this reason these insects are commonly referred to as armored scale insects. As it is so robust and firmly attached to the host plant, the scale often persists long after the insect has died. Some African Diaspididae are attended by ants of genus ''Melissotarsus''. The ants appear to consume the armored scales because Diaspididae are completely naked when ant-attended; the ant nest itself remains completely hidden under the bark of the tree.

Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Myzus Persicae
''Myzus persicae'', known as the green peach aphid, greenfly, or the peach-potato aphid, is a small green aphid belonging to the order Hemiptera. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. It also acts as a vector for the transport of plant viruses such as cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco etch virus (TEV). Potato virus Y and potato leafroll virus can be passed to members of the nightshade/potato family (Solanaceae), and various mosaic viruses to many other food crops. Originally described by Swiss entomologist Johann Heinrich Sulzer in 1776, its specific name is derived from the Latin genitive ''persicae,'' "of the peach". The syntype specimen of this species is located in the Illinois Natural History Survey Insect Collection. Life cycle Life cycle of the green peach aphid varies depending on temperature. A fully completed generation takes approximately 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropoda
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
