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.
Pyrethrum was a genus of several Old World plants now classified as Chrysanthemum or Tanacetum which are cultivated as ornamentals for their showy flower heads. Pyrethrum continues to be used as a common name for plants formerly included in the genus Pyrethrum. Pyrethrum is also the name of a natural insecticide made from the dried flower heads of Chrysanthemum cinerariifolium and Chrysanthemum coccineum. The insecticidal compounds present in these species are pyrethrins.
Fuchsia is a genus of flowering plants that consists mostly of shrubs or small trees. The first to be scientifically described, Fuchsia triphylla, was discovered on the Caribbean island of Hispaniola about 1696–1697 by the French Minim monk and botanist, Charles Plumier, during his third expedition to the Greater Antilles. He named the new genus after German botanist Leonhart Fuchs (1501–1566).
Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. Presently, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia. Joseph Dalton Hooker was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent.
The University of California Botanical Garden is a 34-acre botanical garden located on the University of California, Berkeley campus, in Strawberry Canyon. The garden is in the Berkeley Hills, inside the city boundary of Oakland, with views overlooking the San Francisco Bay. It is one of the most diverse plant collections in the United States, and famous for its large number of rare and endangered species.
The Hiroshima Botanical Garden is located in Saeki-ku, Hiroshima in western Honshū, on the hill facing the Seto Inland Sea. The Garden was opened to the public on 3 November 1976.
Lilium longiflorum, often called the Easter lily, is a plant endemic to both Taiwan and Ryukyu Islands (Japan). Lilium formosanum, a closely related species from Taiwan, has been treated as a variety of Easter lily in the past. It is a stem rooting lily, growing up to 1 m high. It bears a number of trumpet shaped, white, fragrant, and outward facing flowers.
Raphides are needle-shaped crystals of calcium oxalate monohydrate or calcium carbonate as aragonite, found in more than 200 families of plants. Both ends are needle-like, but raphides tend to be blunt at one end and sharp at the other.
The Carl S. English Jr. Botanical Gardens are botanical gardens located on the grounds of the Hiram M. Chittenden Locks at 3015 NW 54th Street, Seattle, Washington.
Fuchsia magellanica, commonly known as the hummingbird fuchsia or hardy fuchsia, is a species of flowering plant in the evening primrose family Onagraceae, native to the lower Southern Cone of southern South America.
The Russian wheat aphid is an aphid that can cause significant losses in cereal crops. The species was introduced to the United States in 1986 and is considered an invasive species there. This aphid is pale green and up to 2 mm long. Cornicles are very short, rounded, and appear to be lacking. There is an appendage above the cauda giving the aphid the appearance of having two tails. The saliva of this aphid is toxic to the plant and causes whitish striping on cereal leaves. Feeding by this aphid will also cause the flag leaf to turn white and curl around the head causing incomplete head emergence. Its host plants are cereal grain crops including wheat and barley and to a lesser extent, wild grasses such as wheatgrasses, brome-grasses, ryegrasses and anything in the grass family.
Rhopalosiphum is a genus of aphid of the family Aphididae that includes 16 species worldwide. Apart from sucking the phloem of host plants and thereby being treated in agriculture as pests, some species are vectors for viral pathogens.
Tulip breaking virus is one of five plant viruses of the family Potyviridae that cause color-breaking of tulip flowers. These viruses infect plants in only two genera of the family Liliaceae: tulips (Tulipa) and lilies (Lilium).
Iris longipetala is a species in the genus Iris, it is also in the subgenus Limniris and in the series Longipetalae. It is a rhizomatous perennial, from North America. It has dark green or bluish green, grass-like leaves, small stem and 3–8 flowers, that range from creamy-white, pale blue to lavender blue. It is cultivated as an ornamental plant in temperate regions.
Megoura viciae is a large, green aphid in the family Aphididae native to Europe that feeds on plants in the genus Vicia. They are commonly known as vetch aphids for this reason.
Rhopalosiphum rufiabdominale, the rice root aphid or red rice root aphid, is a sap-sucking insect pest with a wide host range and a global distribution. As a member of the superfamily Aphidoidea, it is one of 16 species of the genus Rhopalosiphum. Adults and nymphs are soft-bodied and usually dark green with brown, red, or yellow tones. Like all aphids, reproduction is sexual and asexual, depending on the environmental conditions and host plant. Rice root aphids cause injury to external plant parts, namely the roots or stem, by feeding on plant sap and vector several important plant viruses. The hosts of this pest extend across multiple plant families with most belonging to Rosaceae, Poaceae, and Solanaceae. R. rufiabdominale is universally associated with Prunus species but also infests various field crops, greenhouse vegetables, cannabis, and other ornamental plants. While this aphid originates from east Asia, it spans nearly every continent. Dispersal is particularly widespread across the United States, India, and Australia, with crop damage documented in multiple instances, although economic losses are primarily associated with Japanese rice crops. Nonetheless, it remains a pest of serious concern due to its high mobility, discrete habitat, and adaptive plasticity, giving it the rightful reputation as a successful invader.
Hypericum hookerianum, or Hooker's St. John's Wort, is a perennial shrub in the flowering plant family Hypericaceae native to eastern and southern Asia. The specific name hookerianum is named for William Jackson Hooker.
Fuchsia microphylla, also known as small leaf fuchsia and small-leaved fuchsia, is a flowering shrub in the family Onagraceae. The specific epithet (microphylla) was named for the plant's small (micro) leaves (phylla).
