Euaresta Aequalis
''Euaresta aequalis'' is a species of fruit fly in the genus '' Euaresta'' of the family Tephritidae. Description ''E. aequalis'' has elaborate markings on its wings, characteristic of the family Tephritidae, and brilliant green eyes. The diagnostic characters for this species are a tan or yellow body with a clear round spot on the wing in cell r4+5, separated from the wing margin by distinct brown band. All North American species of the genus '' Euaresta'' except ''E. aequalis'' and ''festiva'' have a base color of dark brown to black. This species is generally the largest of the North American '' Euaresta''. It is commonly known as the burr-seed fly. Distribution ''E. aequalis'' is distributed widely across the United States and southern Canada. The species was first observed in Mexico in 1969, in Baja California. It was introduced to Australia in the 1930s in an attempt to control invasive cocklebur.Cullen, J., Julien, M., & McFadyen, R. (2012). ''Biological Control of Weeds ...

Hermann Loew
Friedrich Hermann Loew (19 July 1807 – 21 April 1879) was a German entomologist who specialised in the study of Diptera, an order of insects including flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States. Biography Early years Hermann Loew was born in Weissenfels, Saxony a short distance south of Halle (Germany). The Loew family, though not wealthy, was well-placed. Loew's father was a functionary for the Department of Justice of the Duchy of Saxony who later became a ''Geheimer Regierungsrath'' of Prussia. Between 1817 and 1829 Loew attended first the Convent school of Rossleben, then the University of Halle-Wittenberg, graduating in mathematics, philology and natural history. Teacher, tutor and husband Recognizing his abilities as a mathematician, the university, on his graduation, appointed him as a lecturer in the same subjects. In 1830 he went to Berlin and gave lessons in differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthium
''Xanthium'' (cocklebur) is a genus of flowering plants in the tribe Heliantheae within the family Asteraceae, native to the Americas and eastern Asia and some parts of south Asia . Description Cockleburs are coarse, herbaceous annual plants growing to tall. The leaves are spirally arranged, with deeply toothed margins. Some species, notably ''Xanthium spinosum'', are also very thorny with long, slender spines at the leaf bases. The flower heads are of two types; One, in short terminal branches, produces only pollen. The other, in clusters in the axils of the leaves, produces seed. Unlike many other members of the family Asteraceae, whose seeds are airborne with a plume of silky hairs resembling miniature parachutes, cocklebur seeds are produced in a hard, spiny, globose or oval double-chambered, single-seeded bur long. It is covered with stiff, hooked spines, which stick to fur and clothing and can be quite difficult to detach. These burs are carried long distances fro ...

Rust Fungus
Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales (previously known as Uredinales). An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a very narrow range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. A single species of rust fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host specific, and can typically infect only one kind of plant. Rust fungi are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tortricid
The Tortricidae are a family of moths, commonly known as tortrix moths or leafroller moths, in the order Lepidoptera. This large family has over 11,000 species described, and is the sole member of the superfamily Tortricoidea, although the genus '' Heliocosma'' is sometimes placed within this superfamily. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting posture is with the wings folded back, producing a rather rounded profile. Notable tortricids include the codling moth and the spruce budworm, which are among the most well-studied of all insects because of their economic impact. Description Tortricid moths are generally small, with a wingspan of 3 cm or less.Hanson, Paul E. (04-11-2018). Insects and Other Arthropods of Tropical America. Cornell University Press. Many species are drab and have mottled and marbled brown colors, but some diurnal species are brightly colored and mimic other moths of the families Geometri ...

Stemborer
A stemborer (stem borer) is any insect larva, or arthropod, that bores into plant stems. However the term most frequently refers among the Coleoptera to the larva of certain longhorn beetles such as '' Dorysthenes buqueti'' and those of the genus '' Oberea'', and among the Lepidoptera to certain moths of the Crambidae, Castniidae, Gelechiidae, Nolidae, and Pyralidae families. Stem borers include: ;Coleoptera *Banana stemborer weevil ('' Cosmopolites sordidus'') * Coffee white stem borer (''Xylotrechus quadripes'') * Sugarcane longhorn stemborer (''Dorysthenes buqueti'') ;Lepidoptera *African pink stemborer (''Sesamia calamistis'') * African white stemborer (''Maliarpha separatella'') *Asiatic rice stemborer (striped rice stemborer, ''Chilo suppressalis'') * Banana stem borer (''Telchin licus'') * Egyptian stemborer (''Earias insulana'') *Gold-fringed rice stemborer (''Chilo auricilius'') *Pearl millet stem borer (''Coniesta ignefusalis'') *Spotted stem borer (''Chilo partellus'') * ...

Biological 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] |
Univoltine
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daniel William Coquillett
Daniel William Coquillett (23 January 1856, Pleasant Valley, Ill. – 7 July 1911 Atlantic City, New Jersey) was an American entomologist who specialised in Diptera. He wrote a revision of the dipterous family Therevidae and many other scientific papers in which he described many new species and genera of Diptera. Coquillett was also the first to attempt fumigation with hydrocyanic acid as a means for controlling citrus scale insects. He experimented in the Wolfskill orange groves where he was supported by the foreman and later quarantine entomologist Alexander Craw Alexander Craw (3 August 1850 – 28 June 1908) was a pioneer American economic entomologist. He was the first American entomologist to work in quarantine protection against foreign pests arriving by ship to San Francisco, California. Along with ... in 1888–89.

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Xanthium Strumarium
''Xanthium strumarium'' (rough cocklebur, clotbur, common cocklebur, large cocklebur, woolgarie bur) is a species of annual plants of the family Asteraceae. Some sources claim it originates in southern Europe and Asia, but has been extensively naturalized elsewhere. Others, such as the Flora of China and Flora of North America, state it originates in the Americas but was an early introduction to Eurasia. Reproductive biology The species is monoecious, with the flowers borne in separate unisexual heads: staminate (male) heads situated above the pistillate (female) heads in the inflorescence. The pistillate heads consist of two pistillate flowers surrounded by a spiny involucre. Upon fruiting, these two flowers ripen into two brown to black achenes and they are completely enveloped by the involucre, which becomes a bur. The bur, being buoyant, easily disperses in the water for plants growing along waterways. However, the bur, with its hooked projections, is obviously adapted to disp ...
