Phyllotreta Nemorum
''Phyllotreta nemorum'', the turnip flea beetle or yellow-striped flea beetle is a species of beetle in family Chrysomelidae. The beetle is 2.4-3.5 mm long and black with sinuate yellow bands running down its elytra. It is found in the Palearctic.Joy, N 1932 A Practical Handbook of British Beetles The beetle feeds on various wild and cultivated Brassicaceae, and also on mignonettes ('' Reseda'' spp.) and brooklime ('' Veronica beccabunga''). Adults consume leaves while larvae are leaf-miners. They are themselves preyed on by swifts ('' Apus apus'') and parasitised by braconid and eulophid The Eulophidae are a large family of hymenopteran insects, with over 4,300 described species in some 300 genera.

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are '' Draba'' (440 species), '' Erysimum'' (261 species), '' Lepidium'' (234 species), '' Cardamine'' (233 species), and '' Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as '' Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and co ...

Agricultural Pest Insects
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alticini
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily. Though most tribes of the Galerucinae are suspect of rampant paraphyly in the present delimitation, the Alticini seem to form a good clade. Description and ecology The adults are very small to moderately sized Chrysomelidae (i.e. among beetles in general they are on the smallish side). They are similar to other leaf beetles, but characteristically have the hindleg femora greatly enlarged. These enlarged femora allow for the springing action of these insects when disturbed. Flea beetles can also walk normally and fly. Many flea beetles are attractively colored; dark, shiny and often metallic colors predominate. Adult flea beetles feed externally on plants, eating the surface of the leaves, stems and petals. Under heavy feeding the small roun ...

Eulophidae
The Eulophidae are a large family of hymenopteran insects, with over 4,300 described species in some 300 genera. The family includes the genus '' Elasmus'', which used to be treated as a separate family, "Elasmidae", and is now treated as a subfamily of Eulophidae. These minute insects are challenging to study, as they deteriorate rapidly after death unless extreme care is taken (e.g., preservation in ethanol), making identification of most museum specimens difficult. The larvae of a very few species feed on plants, but the majority are primary parasitoids on a huge range of arthropods at all stages of development. They are exceptional in that they are one of two hymenopteran families with some species that are known to parasitize thrips. Eulophids are found throughout the world in virtually all habitats (one is even aquatic, parasitising water-penny beetles). Eulophids are separable from most other Chalcidoidea by the possession of only four tarsomeres on each leg, a small, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braconidae
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include '' Aerophilus'', '' Aleiodes'', '' Apanteles'', '' Asobara'', '' Bracon'', '' Cenocoelius'', '' Chaenusa'', '' Chorebus'', ''Cotesia'', '' Dacnusa'', ''Diachasma'', ''Microgaster'', '' Opius'', '' Parapanteles'', '' Phaenocarpa'', '' Spathius'', and '' Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the labrum and the lower part of the clypeus are concave with respect to the upper clypeus and the dorsal margin of the mandi ...

Apus Apus
The common swift (''Apus apus'') is a medium-sized bird, superficially similar to the barn swallow or house martin but somewhat larger, though not stemming from those passerine species, being in the order Apodiformes. The resemblances between the groups are due to convergent evolution, reflecting similar contextual development. The swifts' nearest relatives are the New World hummingbirds and the Southeast Asian treeswifts. Its scientific name ''Apus'' is Latin for a swift, thought by the ancients to be a type of swallow with no feet (from Ancient Greek α, ''a'', "without", and πούς, ''pous'', "foot"). Swifts have very short legs which they use primarily for clinging to vertical surfaces (hence the German name ''Mauersegler'', literally meaning "wall-glider"). They never settle voluntarily on the ground, where they would be vulnerable to accidents and predation, and non-breeding individuals may spend up to ten months in continuous flight. Taxonomy The common swift was one o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veronica Beccabunga
''Veronica beccabunga'', the European speedwell or brooklime, is a succulent herbaceous perennial plant belonging to the flowering plant family Plantaginaceae. It grows on the margins of brooks and ditches in Europe, North Africa, and north and western Asia. It can be found on other continents as an introduced species. It has smooth spreading succulent branches that are often reddish, blunt oblong finely serrate leaves in opposite pairs close to the stem, and small bright blue or pink flowers with four petals. The species name ''beccabunga'' comes from Danish ''bekkebunge'' (literally "brook bunch") or a similar source. Medicinal usage Brooklime was one of three traditional antiscorbutic herbs (alongside scurvy grass and watercress), used in purported remedies for scurvy. However none of these herbs are rich in vitamin C Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits and vegetables, also sold as a die ...

Reseda (plant)
''Reseda'' , also known as the mignonette , is a genus of fragrant herbaceous plants native to Europe, southwest Asia and North Africa, from the Canary Islands and Iberia east to northwest India. The genus includes herbaceous annual, biennial and perennial species 40–130 cm tall. The leaves form a basal rosette at ground level, and then spirally arranged up the stem; they can be entire, toothed or pinnate, and range from 1–15 cm long. The flowers are produced in a slender spike, each flower small (4–6 mm diameter), white, yellow, orange, or green, with four to six petals. The fruit is a small dry capsule containing several seeds. Other common names include weld or dyer's rocket (for '' R. luteola''), and bastard rocket. Cultivation and uses Propagation is by seed, which is surface-sown directly into the garden or grass verge. The plant does not take well to transplanting and should not be moved after sowing. Mignonette flowers are extremely fragran ...

A Practical Handbook Of British Beetles
''A Practical Handbook of British Beetles'' is a two-volume work on the British beetle fauna, by Norman H. Joy, first published by H. F. & G. Witherby in January 1932. Contents Volume one (xxviii + 622 pages) consists of the text (largely a set of identification keys, with brief status notes for each species). Volume two (194 pages) contains 2040 line-drawings of whole beetles and features referred to in the keys (390 of these were taken from Spry and Shuckard's 1840 publication ''The British Coleoptera Delineated'' but the remainder were drawn by Joy). The book covers a fauna of about 3560 different species and has an emphasis on species identification, being "essentially a manual of identification for the use of collectors." A reduced-size reprint was produced by E. W. Classey in 1976, and again in 1997, while Pisces Conservation released an electronic version in 2009, solving a longstanding problem of availability.

Arthropod
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] |
Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfre ...
