Aculops Fuchsiae
''Aculops fuchsiae'', commonly known as fuchsia gall mite, is a species of mite in the family Eriophyidae. It feeds on ''Fuchsia'' plants, causing distortion of growing shoots and flowers. It is regarded as a horticultural pest. Description ''Aculops fuchsiae'' is too small to be seen with the naked eye; female adult mites are between long and wide, with males slightly smaller. It is white or pale yellow in colour and has a wormlike or spindle-like body shape, with two anterior (front) pairs of legs. Biology ''Aculops fuchsiae'' is host specific and the only eriophyid mite known to attack ''Fuchsia''. It feeds on the shoot tips, where it sucks sap. It produces chemicals that interfere with the plant's normal growth, which instead becomes a distorted mass of reddish-pink or yellowish green tissue. There are several generations between late spring and autumn; the life cycle takes about 21 days at 18°C. There are four life stages: egg, larva, nymph and adult. Eggs take between 4 ...

Hartford H Keifer
Hartford Hammond Keifer (24 January 1902 – 20 August 1986) was a world authority on eriophyid mites. Based in California, he initially studied the local microlepidoptera before turning to mites in 1937. Personal life Keifer was born 1902 in Oroville, California, to John McCarl Keifer (1861–1928) and Elizabeth Burt (née Leggett; 1863–1922). As a child he had an interest in natural history and insects, and was encouraged by an aunt, Dr. Cordelia Burt Leggett. From 1920 to 1924, he attended the University of California, Berkeley and gained a Bachelor of Science degree in entomology. He married Mary Isabelle (née Ost; 1906–1990) in August 1928 and moved to Sacramento to work at the California State Department of Agriculture. Biography After graduation, Keifer worked for the Forest Service before accepting a position as an assistant to the curator at the California Academy of Sciences, San Francisco where he mounted and labelled a backlog of material. In 1925 he joined t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuchsia Magellanica
''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. Description This sub-shrub can grow to in height and width in frost-free climates, and where colder. The plant blossoms profusely over a long period with many small and tubular pendent flowers, in brilliant shades of red and purple, softer shades of pink and lavender, and some in white. ''F. magellanica'' is a consistently variable species across the whole of its natural range and, despite past usage and popular misconceptions, no scientific varieties are currently recognized by botanist Dr. Paul E. Berry, the leading authority on the genus. Care should be taken not to accord any of the many garden selections and hybrids with taxonomic status by using "var." Additionally, pollen stain tests conducted in the Pacific Northwest region of the United States by mem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animals Described In 1972
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms ...
