Coccinellidae
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 "scarl ...

Galinsoga Parviflora
''Galinsoga parviflora'' is a herbaceous plant in the Asteraceae (daisy) family. It has several common names including guasca (Colombia), pacpa yuyo, paco yuyo and waskha (Peru), burrionera (Ecuador), albahaca silvestre and saetilla (Argentina), mielcilla (Costa Rica), piojito ( Oaxaca, Mexico), galinsoga (New Zealand), gallant soldier, quickweed, and potato weed (United Kingdom, United States). History ''Galinsoga parviflora'' was brought from Peru to Kew Gardens in 1796, and later escaped to the wild in Great Britain and Ireland, being temporarily known as the 'Kew Weed'. The plant is named after the Spanish botanist Ignacio Mariano Martinez de Galinsoga. The species name parviflora''' translates to 'having small flowers'. In Britain, its name ''Galinsoga'' is sometimes popularly rendered as "gallant soldiers", and then sometimes altered to "soldiers of the Queen".

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.

Aphis Gossypii
''Aphis gossypii'' is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. Common names include cotton aphid, melon aphid and melon and cotton aphid. Distribution It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. It is common in North and South America, Central Asia, Africa, Australia, Brazil, East Indies, Mexico and Hawaii and in most of Europe. It is cosmopolitan in habitat. It thrives outdoors in southern Europe but survives only under glass in northern Europe. In the former Soviet Union it is found up to 54°N. Morphology The wingless female cotton aphid has an ovoid body about two millimetres long in varying shades of green. The legs are yellow, as are the antennae whi ...

Aphis Rumicis
''Aphis'' is a genus of insects in the family Aphididae containing at least 600 species of aphids. It includes many notorious agricultural pests, such as the soybean aphid ''Aphis glycines''. Many species of ''Aphis'', such as '' A. coreopsidis'' and '' A. fabae'', are myrmecophiles, forming close associations with ants.

Brachycaudus Helichrysi
''Brachycaudus helichrysi'' is a species of aphid first described by the German naturalist Johann Heinrich Kaltenbach in 1843. Its common names include leaf curl plum aphid, and leaf-curling plum aphid, and it is a serious pest of plum and damson trees. Description The viviparous wingless females have an oval or pear-shaped body and grow to a length of up to . Early in the season they are brownish but later they are yellowish-green. The antennae are pale green and short, about half the length of the body. There is no dark, shining patch on the dorsal surface of the abdomen, a fact which distinguishes it from the otherwise similar thistle aphid ('' Brachycaudus cardui''). The cauda (tail-like elongation) is bluntly rounded, the legs are pale except for the extremities, and the cornicles are pale-coloured, short and flanged. Winged females range from in length and have a blackish head with longer antennae, blackish thorax and a green abdomen with dark spots on the third to sixth ...

Brevicoryne Brassicae
''Brevicoryne brassicae'', commonly known as the cabbage aphid or cabbage aphis, is a destructive aphid (plant louse) native to Europe that is now found in many other areas of the world. The aphids feed on many varieties of produce, including cabbage, broccoli (especially), Brussels sprouts, cauliflower and many other members of the genus ''Brassica'', but do not feed on plants outside of the family Brassicaceae. The insects entirely avoid plants other than those of Brassicaceae; even though thousands may be eating broccoli near strawberries, the strawberries will be left untouched.University of Minnesota extension Cabbage aphids, from the '' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Insects Of Sri Lanka
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
