Hayhurstia are medium-sized aphids, with very small slightly swollen siphunculi. The podocarpus aphid is found in its native range of China, Japan, Malaysia, and Taiwan, the Riao Islands of Indonesia, New Zealand, and Australia. The forewing of the alate has the median vein only once branched. We often visited there to look for Wanderer Butterflies. The antennae are longer than the body, with secondary rhinaria in both the apterae and alatae. This genus includes seven species (four nearctic and three palaearctic) all of which feed on the needles of pine (Pinus). The antennae are about as long as the body or longer, with inconspicuous hairs. 2015). The antennal tubercles are well-developed and the antennae are longer than the body. The antennae are shorter than the body. The podocarpus aphid is recognizable by its blueish purple color (Figure 1). They are not attended by ants. These are large distinctive aphids with short antennae only about 0.3-0.4 times the body length. as the primary host and various daisies (Asteraceae) and Scrophulariaceae as secondary hosts. These aphids, like for example Forda, Geoica, Paracletus, Prociphilus and some Trama, have no siphunculi. (b) The primary rhinaria on the last two segments have thick, hairless, sclerotized rims. Small to medium-sized aphids (alate body length usually 2 - 3 mm) which have short antennae and siphuncular pores. Scientists have given each and every recognized species on earth its own scientific names to uniquely identify them to avoid confusion. Colopha is a small aphid genus, related to the genus Kaltenbachiella. A few species alternate from Rosaceae to grasses, but the majority of species remain on grasses (Poaceae) all year. Foottit RG, Maw HEL, Pike KS, Messing RH. Prociphilus species range from rather small to very large aphids. The head is broad and lacks antennal or median tubercles. The rostrum is rather long. The single species is thought to be an important vector of plant viruses. Several species are restricted to wetland or coastal habitats. Wingless females are dorsoventrally flattened and have peculiar projections on the head and prothorax. Some of the American species have been introduced to Europe. It has a sexual stage in its life cycle, but does not host alternate. The rostrum is distinctive in having a long and almost needle-like last rostral segment. About 24 species in North America, Europe and eastern Asia. It is characterised by the antennal terminal process on both winged and wingless adults being vestigial, less than 0.1 times the length of the base of the last antennal segment. Small elongate-oval aphids the adult viviparae of which may be winged or wingless. There are 14 Trama species worldwide, mostly living on the roots of Asteraceae where they are attended by ants. Forms on the secondary host often produce abundant wax. The abdomen has dark dorsal markings. The dorsum of the aptera is sclerotic or granulate with very short hairs. Each has its own distribution in Europe and North Africa (Atlantic, Pannonian and Mediterranean). ), whilst others remain all year on birch. Ericaphis feed on heaths (Ericaceae), Rosaceae and Liliaceae. The distribution is holarctic with 12 species worldwide. blind mole-rats (Species: 1, Individual: 1) They can be a serious pest on walnuts. Small delicate narrow-bodied aphids with a knobbed cauda. Other species live year round on the roots of grasses (Poaceae) or sedges (Cyperaceae). There is only one species in the genus Caricosipha paniculatae which feeds on greater tussock sedge (Carex paniculata) and the true fox sedge (Carex vulpina). Both the sexual and parthenogenetic females are oviparous. Very large aphids with a body length of 3.3 - 4.3 mm. Stomaphis feed on the stems and roots of a variety of tree species, A species name* is written in italics with the first word beginning with a capital letter. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006). It does not host alternate and does not appear to have a sexual stage in the life cycle. Paramyzus have well developed steep-sided antennal tubercles and long antennae, with a long terminal process. These are medium-sized aphids which look rather like some Myzus species. Medium sized aphids the adult viviparae of which may be winged or wingless. They have very low divergent antennal tubercles. The adult viviparae may be winged or wingless. They are not ant attended, but sometimes occur in mixed colonies with ant-attended species such as Tuberolachnus salignus. Baizongia alatae hold their wings roof-like when at rest, and the pterostigma has a dark central patch. Apterae are generally small to medium sized and pale coloured. The siphunculi are stump-shaped with a pronounced flange. The siphunculi are swollen and the wing veins are dark-bordered. There are about 15 species, 11 of which are in North America, two are European and one is east Asian. The rostrum is short, not reaching the middle coxae. The head is rough with spicules. In warmer climates they may reproduce viviparously throughout the year. The antennae are about half as long as body. Wingless adults (shown here) are greenish-gray or gray with a dark sclerotic dorsal abdominal plate. This is a very large genus sometimes assigned to its own subfamily, with species on conifers of the families Pinaceae and Cupressaceae. The cauda is knobbed and the anal plate is rounded. Most species retain a sexual stage in the life cycle and host alternate. Large populations of podocarpus aphids can cause stunting and curling of new growth on host Podocarpus plants (Figure 3, Figure 4). The fundatrices have no wax glands. Three species have lost their primary host and their sexual stages and live parthenogenetically year-round on grasses and sedges. Some of the more common species are listed below. The dorsum is pigmented usually greenish or blackish with many conspicuous hairs. A large genus of over 80 species worldwide. They have a sexual stage in the life cycle, but do not host-alternate. Most live on plants of the heather family (Ericacaceae), but with one on rose (Rosaceae) in North America. The cauda is finger or tongue-shaped. There are secondary rhinaria only on antennal segment 3. They have no antennal tubercles, and the front of the head is convex. Also the apterae on the secondary host have one-segmented tarsi. The cauda is tongue shaped, slightly constricted near the base. the President of your country). The fundatrices feed in spring on pear (Pyrus, Rosaceae), typically crumpling or rolling the leaves into pseudogalls. Another aphid in the same genus, Neophyllaphis varicolor, is often seen on podocarpus plants in Florida and appears similar to the podocarpus aphid, except the nymphs of these aphids can be yellow, orange, red, or purple in color (Miller and Halbert 2014). Aphids are medium-sized on winter hosts (2.0 - 2.6mm long), but small on summer hosts. In northern areas the populations are anholocyclic on grass roots. The siphunculi are rather long, cylindrical, with little or no apical reticulation The cauda is elongate and rather blunt finger-shaped. DNA barcoding reveals a mysterious high species diversity of conifer-feeding aphids in the mountains of southwest China. One species is an important pest of plum trees which are affected by fungi growing on the honeydew-coated leaves. Rather large aphids which are similar to Amphorophora in many respects, but have fewer caudal hairs. Spring colonies distort and discolour the leaves of apple and related trees (Rosaceae), before migrating to secondary hosts in umbellifers (Apiaceae) and other families. View all citations for this article on Scopus × Access; Volume 91, Issue 10 ; October 1959, pp. The body is grey-green and usually covered with a dense coat of flocculent wax The siphuncular cones are small and pale. They are cryptic when feeding, but very active when disturbed. There are 8 or more species worldwide feeding on the growing tips and young cones of spruces or firs. The antennae are shorter than the body and are without secondary rhinaria in the apterae. About half live on berries (Rubus: Rosaceae) and a few live on ferns. In such cases one name is chosen for the species and the other names are referred to as "synonyms" of the species name. There are three highly polyphagous species which are important pests. Their antennae have a relatively long terminal process with a few rhinaria on segment III. The genus is oriental in origin, but several species are now widely distributed. Usually all viviparae are alate. Frequently a particular individual of a species will mutate to a diverse colour, size, or growth habit. eukaryotes named Cercozoa; Ipomovirus genus members are transmitted by whiteflies, whereas the vectors of single-species genera Brambyvirus, Bevemovirus and Roymovirus are unknown [6]. for 'a species' or 'spp.' A small genus with only three species of aphids, two of which are only found in the Far East (subgenus Tuberolachniella). The siphunculi are longer than the cauda and have an apical expansion followed by a constriction below a strong flange. Paramyzus are not attended by ants. The apical rostral segment (RIV+V) is much longer than the second hind tarsal segment (HTII). A species name should have two parts as a binomial system: (1) generic name and (2) specific epithet. The body has numerous capitate hairs. A palaearctic genus of about 110 species. Adult viviparae may be winged or wingless. Most of the species (those in the subgenus Neotrama) have siphuncular pores on low cones, but the three species in the nominate subgenus have neither siphunculi nor siphuncular pores. The median frontal tubercle is less well developed. They have a sexual stage in the life cycle, but do not host alternate. Staticobium are medium to large aphids. Apterae on the secondary host differ from Kaltenbachiella apterae in having the fore-tarsi parallel-sided, with a ventral hair arising from a distal protrusion. Medium-sized to large elongate long-legged aphids. Antennal tubercles very weakly developed. The cauda is finger- or tongue-shaped. All adults apart from oviparae are winged insects. A genus of large aphids which tend to have aposematic colouration because they sequester toxins from the host plant Aconitum. The cauda is dark or pale and is tongue- or finger-shaped, at least 1.4× its basal width in dorsal view. in winter/spring and common reed (Phragmites) in summer, or may live year round on either host. Macrosiphum rosae (Linnaeus, 1758) Common Names. Antennal tubercles are well developed with two additional bumps on head The siphunculi are longer than the cauda. The body has numerous capitate hairs arising from tubercles on the body - just visible in this image. They have a sexual stage in the life cycle. Registers of Family-Group and Genus-Group Taxa of Aphidoidea (Hemiptera Sternorrhyncha) 178 >> Clypeoaphis Type species: Clypeaphis suaedae Soliman (= Clypeoaphis suaedae suaedae), by original designation No first use as family-group name is recorded in the database. A genus of fragile pale whitish, straw-coloured or very pale green aphids the adult viviparae of which may be winged or wingless. The frontal region of head is smooth. The extant species, Paraponera clavata , is found in Central America and South America, and the pain from its sting is said to be greater than any other insect sting on earth. Medium-sized yellowish to black aphids, the adult viviparae of which may be winged or wingless. With one exception (Longicaudus naumanni) the siphunculi are shorter than the cauda, often much shorter (<0.5 times). The antennal tubercles are well developed with diverging or parallel inner sides. But instead of producing a gall on the leaf lamina, first instar Kaltenbachiella fundatrices cause a gall near the base of leaf mid-rib. Small to medium-sized green, straw-coloured or ochreous-reddish aphids. The first picture (right) shows the aphid as it appears in life. The siphunculi are short and dark and slightly longer than the cauda. Aphids come in a variety of species. The birch-feeding species may have black dorsal abdominal markings. They have short appendages and other morphological features adapted to their mode of life. The antennae are short. The group includes the fluffy white woolly aphids. Terminal leaf damage on podocarpus caused by podocarpus aphids, Neophyllaphis podocarpi Takahashi. Some are host specific - others are found on a great variety of different plants, but never on sedges (Cyperaceae) and very rarely on grasses (Poaceae). The winged viviparae that emerge from these galls have a black head and pterothorax and a rather elongate greenish wax-dusted abdomen. Antennae are shorter than the body and have a very short antennal PT . The siphunculi vary in size and shape. Small, narrow and elongate greenish to olive brown aphids with long limbs. They are not attended by ants. Many species in the two main subgenera are associated with the heath and rhododendron family (Ericaceae), but others feed on taxonomically diverse plants. Wingless adults on secondary hosts are pear-shaped or globular and have a fused and pigmented head and prothoracic shield. The empodial hairs are spatulate. The genus is the bigger grouping; to get more specific in identifying a plant within a genus, we refer to its specific epithet. They do not host alternate and are not attended by ants. Other words only begin with a capital if they are proper nouns (including host genus names but not virus genus names**) or alphabetical identifiers. Small to medium-sized to elongate oval or pear-shaped aphids closely related to Rhopalosiphum aphids. The clypeus bears a forward directed tubercle, and the ratio of the terminal process of the last antennal segment to its base is about 1. They typically feed along the midrib of the upper surface of the leaves. Males have been recorded, but most populations have probably lost the sexual stage in the life cycle. The genus Aphidius contains many species that provide biological control of aphids in agricultural crops, greenhouses, urban landscapes, and home gardens. The following codes are used today: 1. Control of the podocarpus aphid is usually not necessary unless numbers become high enough to cause considerable plant damage. Genus is a group of plants which are related to each other in some or the other way. These are long-bodied aphids, similar to Eulachnus, but smaller and with 5-segmented antennae. This genus includes about 22 species which mainly feed on the twigs and branches of broadleaved trees especially oaks, chestnuts and beeches (Fagaceae). The Latin scientific name of a species, be it plant, animal, bacterium, fungus, etc., is a two-part name consisting of the genus name first (by the way: one genus, two genera) and the species name second. There is only one species in this genus. The winged forms have no black central abdominal patch. About 14 North American species, all living on pine (Pinus) needles except for one species on Douglas fir ( Pseudotsuga). Some feed on only one or two plant species, but others can be found on a wide range of plant hosts. Image copyright Maria Fremlin, all rights reserved. Linnaeus created the system of “binomial nomenclature,” which uses only two designations–genus and specific epithet as the species name.In the mid-1800s, scientists agreed on an expanded system of nomenclature. A genus of eight species all living on the leaves of sycamore or maple (Aceraceae). Very small to rather large aphids. They have a sexual stage in the life cycle overwintering as eggs, but there is no host alternation. Prociphilus have lost their evolutionary constraint to Populus and transferred their sexual generation in relatively recent times to live in pseudogalls on various more advanced "primary" hosts, e.g. They are not attended by ants. Siphunculi are long, flanged and not swollen, with a zone of regular polygonal reticulations covering the one-tenth to one-sixth near the end of the siphunculus. It may not work for all fundatrices or alatae and apterae from primary hosts (for those species with host alternation). Emigrant alates have a dark head and thorax and a pale body. In contrast to a wood’s common name, using the scientific or botanical name is a much more precise way of referencing wood: the only downside is that it’s Latin. The cauda is elongate triangular and much shorter than the siphunculi. The antennae are usually about half as long as body. When this happens, a population of plants exists with the same scientific name, but a sub-group displays different characteristics. Many can only raise successful colonies on one plant species. There are 31 species in the world. The complete life cycle of these species takes two years. The secondary host is a herbaceous plant where they form colonies on the roots or in a woolly wax mass above soil level. There are just 2 species in this genus feeding on the undersides of Walnut (Juglans spp.) The siphunculi are cylindrical, thin but with a broader base and with a constriction below the apical flange. They host alternate from various willow (Salicaceae) species as the primary host to various umbellifers (Apiaceae) as the secondary host. The characteristics of the genus are intermediate between Ovatus and Myzus. It consists of a collection of different species with similar characteristics. Spiracles are covered by tubercle-like opercula, an adaptation to regular immersion. change its url; duplicate it; make private; download it; delete it Cryptosiphum are rather small oval aphids that live within galls on mugworts (Artemisia species). Hitherto unknown and poorly known sexual morphs of three Asiatic species of the aphid genus Uroleucon (Hemiptera: Aphididae) October 2020; … Lives on chrysanthemum (Chrysanthemum), tansy (Tanacetum) and other members of the Anthemidae in the Asteraceae. A small genus with only three species of aphids, two of which are only found in the Far East (subgenus Tuberolachniella). Next, write the specific epithet, or the species' name, after the genus name. There are only 1-2 species in the genus. Phylloxera feed on plants in the walnut (Juglandaceae) and oak/chestnut (Fagaceae) families. Importance of Aphids Aphids are also called as plant lice and considered as polyphagous feeders because they munch on several species of ornamental plants, field crops, vegetables, fruits, weeds, grasses, and greenhouse, polyhouse, indoor and nursery plants (Photo 1. are aphid elimination specialists. In winged forms there are often dark segmental bars connecting the muscle plates on abdominal segments 3-5. Mimeuria ulmiphila makes a leaf-nest gall on maple. Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. This variation may occur geographically within a species. The siphunculi are stump shaped and the cauda is knobbed. The body is broadly oval in shape, never very elongate. The terminal (fused 4th and 5th) rostral segment is pointed or stiletto-shaped. Siphunculi are rather long, blackish and sclerotic, with the apical part reticulated and a small but distinct flange. Learn more about AphID. They do not host alternate, but remain all year on members of the Asteraceae, especially those in the tribe Anthemideae. Within the class Hexapoda there are over 750,000 different species of insects. Most of the 600 or so aphid species in Britain feed on a single genus or species of plant, where they suck phloem sap, and are not pests. There are about 19 species living on a great variety of plants, including Labiatae, Rosaceae, Iridaceae, Araliaceae and Grossulariaceae. Therioaphis feed on members of the pea and bean family (Fabaceae). Colonies may be dispersed or aggregated. Colonies are almost always attended by ants. Those of the apterae lack secondary rhinaria, whilst those of alates have secondary rhinaria on segments 3 or 3-4. About 4 species worldwide on various trees and shrubs. The winged forms have dark forewing veins with the media vein twice-branched. Cauda tongue-shaped and longer than its basal width. Antennal tubercles smooth, with inner faces divergent. Winged forms have forewings with an elongate pterostigma, tapering to a point at the wing apex. The cauda is elongate, constricted near the middle. They are not attended by ants. The remaining species, Tuberolachnus salignus is cosmopolitan, and feeds on willows (Salicaceae). The siphunculi are entirely dark. They often live in cryptic habitats near the ground. This North American genus is related to Pterocallis. The sclerotic markings of wings and body of alatae are pale to darkish grey or brown, not black. Laingia are narrow-bodied aphids. A genus of about 80 species worldwide living without host alternation on various dicots, particularly Fabaceae, Rosaceae, and Euphorbiaceae. They have a sexual stage in their life cycle but do not host alternate and are not attended by ants. The species name and scientific name are synonyms. Spruce trees are all coniferous evergreen trees of the genus Picea. About 7 species feeding on members of the bean family (Fabaceae). Winged forms have a trapezoidal black patch on dorsum in front of the siphunculi. The antennal tubercles are rather high, smooth, and divergent. The winged females will often have small scent glands, called pseudosensoria, present on their hind tibiae (the first segment of their hind legs) (Russell 1982). The scientific name of a species is always a double name (the genus name, and a specific name). There are only four species in this genus living mostly on nettles (Urticaceae). The female aphids can be winged or wingless. The dorsal cuticle is usually shiny black and strongly sclerotized. The secondary host is the roots or stems of plants such as buttercups (Ranunculus: Ranunculaceae) and Lysimachia (Myrsinaceae). They have a sexual stage in the life cycle overwintering as eggs, but there is no host alternation. Oviparae and males are wingless and reduced in size. Adult viviparae are all winged, except in a few species. in Europe and much of Asia; also recorded from the USA. They do not host alternate and are not attended by ants.
