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 telescopic development—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.
Gooseberry is a common name for many species of Ribes, as well as a large number of plants of similar appearance. The berries of those in the genus Ribes are edible and may be green, orange, red, purple, yellow, white, or black.
The blackcurrant, also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically.
Galls or cecidia are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology.
Ribes is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The various species are known as currants or gooseberries, and some are cultivated for their edible fruit or as ornamental plants. Ribes is the only genus in the family Grossulariaceae.
The redcurrant or red currant is a member of the genus Ribes in the gooseberry family. It is native across Europe. The species is widely cultivated and has escaped into the wild in many regions.
Ribes uva-crispa, known as gooseberry or European gooseberry, is a species of flowering shrub in the currant family, Grossulariaceae. It is native to Europe, the Caucasus and northern Africa. Gooseberry bushes produce an edible fruit and are grown on both a commercial and domestic basis. Its native distribution is unclear, since it may have escaped from cultivation and become naturalized. For example, in Britain, some sources consider it to be a native, others to be an introduction. The species is also occasionally naturalized in scattered locations in North America.
Ribes sanguineum, the flowering currant, redflower currant, red-flowering currant, or red currant is a North American species of flowering plant in the family Grossulariaceae, native to the western United States and Canada.
Cecidophyopsis ribis is an eriophyid mite which is best known for being a plant parasite, a pest of Ribes species, the genus that includes gooseberries and blackcurrants. It is commonly known as the blackcurrant gall mite or big bud mite. It feeds on the plants' buds, forming galls, and transmits a virus which causes blackcurrant reversion disease. The mite is a serious pest of blackcurrant crops in Europe, but rarely on other continents.
The jostaberry is a complex-cross fruit bush in the genus Ribes, involving three original species, the blackcurrant R. nigrum, the North American coastal black gooseberry R. divaricatum, and the European gooseberry R. uva-crispa. It is similar to Ribes × culverwellii, the jochelbeere, which is descended from just two of these species, R. nigrum and R. uva-crispa.
Ribes viburnifolium, is an uncommon North American species in the gooseberry family. It is known by the common names Catalina currant, Santa Catalina Island currant, island gooseberry and evergreen currant.
The white currant or whitecurrant is a group of cultivars of the red currant, a species of flowering plant in the family Grossulariaceae, native to Europe. It is a deciduous shrub growing to 1 m (3 ft) tall and broad, with palmate leaves, and masses of spherical, edible fruit (berries) in summer. The white currant differs from the red currant only in the colour and flavour of these fruits, which are a translucent white and sweeter.
The red-pea gall or red currant gall develops as a chemically induced distortion arising from the underside of the mid-rib of a vein on Quercus species and it is attached by a short stalk or peduncle. The red-wart gall is the sexual phase of the same species.
Ribes speciosum is a species of flowering plant in the family Grossulariaceae, which includes the edible currants and gooseberries. It is a spiny deciduous shrub with spring-flowering, elongate red flowers that resemble fuchsias, though it is not closely related. Its common name is fuchsia-flowered gooseberry. It is native to central and southern California and Baja California, where it grows in the scrub and chaparral of the coastal mountain ranges.
Ribes montigenum is a species of currant known by the common names mountain gooseberry, alpine prickly currant, western prickly gooseberry, and gooseberry currant. It is native to western North America from Washington south to California and east as far as the Rocky Mountains, where it grows in high mountain habitat types in subalpine and alpine climates, such as forests and talus. It is a spreading shrub growing up to 1.5 meters tall, the branching stems covered in prickles and hairs and bearing 1 to 5 sharp spines at intervals.
The Pineapple gall adelgid is a type of conifer-feeding insect that forms pineapple-shaped plant galls on its host species, commonly Norway and Sitka spruce. The adelgids are pear-shaped, soft-bodied green insects with long antennae, closely related to the aphid. "Adelges" lays up to one hundred eggs at a time, one on each needle. Adelges abietis is one of the most common species; synonyms are A. gallarum-abietis, Chermes abietis and Sacciphantes abietis.
Rheum ribes, the Syrian rhubarb or currant-fruited rhubarb, or warty-leaved rhubarb, is an edible wild rhubarb species in the genus Rheum. It grows between 1000 and 4000 m on dunite rocks, among stones and slopes, and is now distributed in the temperate and subtropical regions of the world, chiefly in Western Asia to Afghanistan and Pakistan and also in ladakh(Kargil) region of India. The Syrian rhubarb is a partially commercial vegetable collected from the nature in Eastern and Southern Anatolia, Northern Iraq and partly Northwestern Iran in early spring. Rheum ribes is considered as a valuable medicinal species in herbal medicine.
Euura viminalis is a species of sawfly belonging to the family Tenthredinidae. The larva feed within galls on the leaves of willows. It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae.
