Woolly Apple Aphid
''Eriosoma lanigerum'', the woolly apple aphid, woolly aphid or American blight, is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. Description The adults of ''Eriosoma lanigerum'' are small to medium-sized aphids, up to 2mm long, and have an elliptical shape, are reddish brown to purple in colour but the colour is normally hidden by the white cotton-like secretion from the specialised glands in the aphid's abdomen which gives it the common name of woolly apple aphid. The wax is produced after each moult so newly moulted individuals lack the wax coating, the main purpose of which is thought to be to prevent the honeydew secreted by the aphids to contaminate them but it may also produce a shelter from the weather and from parasites and predators. It has sooty-brown antennae has six segments and the colour of the tibias varies from dark brown to yellowish. When the adults are crushed they leave a blood red stain. The pres ...

Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codling Moth
The codling moth (''Cydia pomonella'') is a member of the Lepidopteran family Tortricidae. They are major pests to agricultural crops, mainly fruits such as apples and pears. Because the larvae are not able to feed on leaves, they are highly dependent on fruits as a food source and thus have a significant impact on crops. The caterpillars bore into fruit and stop it from growing, which leads to premature ripening. Various means of control, including chemical, biological, and preventive, have been implemented. This moth has a widespread distribution, being found on six continents. Adaptive behavior such as diapause and multiple generations per breeding season have allowed this moth to persist even during years of bad climatic conditions. Geographic distribution Although the geographic origin of codling moths is unclear, there are theories of these moths originating from either Europe or the Mediterranean. Scholars believe that the codling moths were introduced to the Americas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coccinella Septempunctata
''Coccinella septempunctata'', the seven-spot ladybird (or, in North America, seven-spotted ladybug or "C-7"), is the most common ladybird in Europe. Its elytra are of a red colour, but punctuated with three black spots each, with one further spot being spread over the junction of the two, making a total of seven spots, from which the species derives both its common and scientific names (from the Latin ' = "seven" and ' = "spot"). Biology ''C. septempunctata'' has a broad ecological range, generally living where there are aphids for it to eat. and including, amongst other biotopes, meadows, fields, Pontic–Caspian steppe, parkland, gardens, Western European broadleaf forests and mixed forests. Both the adults and the larvae are voracious predators of aphids, and because of this, ''C. septempunctata'' has been repeatedly introduced to North America as a biological control agent to reduce aphid numbers, and is now established in North America. It has been designated the offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forficula Auricularia
''Forficula auricularia'', the common earwig or European earwig, is an omnivorous insect in the family Forficulidae. The European earwig survives in a variety of environments and is a common household insect in North America. The name ''earwig'' comes from the appearance of the hindwings, which are unique and distinctive among insects, and resemble a human ear when unfolded; the species name of the common earwig, ''auricularia'', is a specific reference to this feature. They are considered a household pest because of their tendency to invade crevices in homes and consume pantry foods, and may act either as a pest or as a beneficial species depending on the circumstances (see below). ''Forficula auricularia'' is reddish-brown in color, with a flattened and elongate body, and slender, beaded antennae. An obvious feature of earwigs is the pair of 'pincers' or forceps at the tip of the flexible abdomen. Both sexes have these pincers; in males they are large and very curved, whereas in ...

Earwig
Earwigs make up the insect order Dermaptera. With about 2,000 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forcep-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings". Some groups are tiny parasites on mammals and lack the typical pincers. Earwigs are found on all continents except Antarctica. Earwigs are mostly nocturnal and often hide in small, moist crevices during the day, and are active at night, feeding on a wide variety of insects and plants. Damage to foliage, flowers, and various crops is commonly blamed on earwigs, especially the common earwig ''Forficula auricularia.'' Earwigs have five molts in the year before they become adults. Many earwig species display maternal care, which is uncommon among insects. Female earwigs may care for their eggs, and even after they have hatched as nymphs will continue to ...

Lacewing
The insect order Neuroptera, or net-winged insects, includes the lacewings, mantidflies, antlions, and their relatives. The order consists of some 6,000 species. Neuroptera can be grouped together with the Megaloptera and Raphidioptera in the unranked taxon Neuropterida (once known as Planipennia) including: alderflies, fishflies, dobsonflies, and snakeflies. Adult Neuropterans have four membranous wings, all about the same size, with many veins. They have chewing mouthparts, and undergo complete metamorphosis. Neuropterans first appeared during the Permian period, and continued to diversify through the Mesozoic era. During this time, several unusually large forms evolved, especially in the extinct family Kalligrammatidae, often called "the butterflies of the Jurassic" for their large, patterned wings. Anatomy and biology Neuropterans are soft-bodied insects with relatively few specialized features. They have large lateral compound eyes, and may or may not also have o ...

Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

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 ...

Anthocoris Nemoralis
''Anthocoris nemoralis'' is a true bug in the family Anthocoridae. The species is native to Europe and is introduced in North America. It is a predator of aphids, spider mites and jumping plant lice, and is therefore used as a biological pest control agent. Description The adult of this species is about long and is mostly black, with white markings on its wings. The nymphs grow to about long, the smaller nymphs being yellowish to orange, and the larger ones having a yellowish to orange head and thorax and a darker coloured abdomen. Distribution ''Anthocoris nemoralis'' has a West Palearctic distribution and is found from the British Isles across Western Europe East to the Caucasus and South to the Mediterranean basin. It is absent from Fennoscandia. It was introduced into Eastern Canada accidentally, and then in 1963 was introduced purposefully into British Columbia in an attempt to control pear psylla. Later it spread southwards to California where it feeds on various ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
