Alfred Nalepa
Alfred Nalepa (19 December 1856, in Werschetz – 11 December 1929, in Baden bei Wien) was an Austrian zoologist specializing in the field of acarology. He studied natural sciences at the University of Vienna, and from 1886 was associated with the ''Lehrerbildungsanstalt'' in Linz. In 1892 he returned to Vienna, where he was appointed professor of natural history at the ''Elisabethgymnasium''. He described many species in the field of acarology, and was the taxonomic authority of the gall mite family, Eriophyidae.

Eriophyidae
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly researched family. They are microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species. Notable species Notable species in this family include: *''Abacarus hystrix'', the cereal rust mite *'' Abacarus sacchari'', the sugarcane rust mite *'' Acalitus essigi'', the redberry mite, which affects blackberries *''Aceria chondrillae'', the chondrilla gall ...

Malus
''Malus'' ( or ) is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples, wild apples, and rainberries. The genus is native to the temperate zone of the Northern Hemisphere. Description Apple trees are typically talI at maturity, with a dense, twiggy crown. The leaves are long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink, or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree days (varying greatly according to subspecies and cultivar). Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); these are called self-sterile, so self-pollination is impossible, making pollinating insects essential.

Phyllocoptes Malinus
''Phyllocoptes malinus'', also known as the apple leaf mite, is a species of mite belonging to the genus ''Phyllocoptes''. It causes a gall, which is a swelling on the external tissues, on the leaves of apples (''Malus'' species). The mite is found in Europe and was first described by the Austrian zoologist Alfred Nalepa in 1892. Description of the gall Sometimes mistaken for a fungal infection, various species of mite develop irregular rust-like erineum; the commonest is caused by the apple leaf mite. The mites live and feed amongst minute, globular or wooly hairs on either side of the leaf, during the summer. The erineum are whitish-pink or red at first, later becoming rust-brown. Purple leaved varieties of ''M. sylvestris'' are particularly colourful. Infected leaves may fall in the late summer but the mites do not have a serious effect on the host tree. During the winter the mites are dormant living in the buds or under loose bark. The apple leaf mite is monophagous on speci ...

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) 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. In human pathology, a gall is a raised sore on the skin, usually caused by chafing or rubbing. Causes of plant galls Insects and mites Insect galls are the highly distinctive plant structures formed by some herbivorous insects as their own microhabitats. They are plant tissue which is controlled by the insect. Galls act as both the habitat a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Phyllocoptes Goniothorax
''Phyllocoptes goniothorax'' is a species of mite belonging to the genus ''Phyllocoptes'', which causes galls on the leaves of hawthorns (''Crataegus'' species). It was first described by Alfred Nalepa Alfred Nalepa (19 December 1856, in Werschetz – 11 December 1929, in Baden bei Wien) was an Austrian zoologist specializing in the field of acarology. He studied natural sciences at the University of Vienna, and from 1886 was associated with th ... in 1889. Description There are two types of galls on the leaves of hawthorns. The mites overwinter in a bud or in bark crevices, emerging to attack the new leaves as soon as the buds open, forming tight rolls on the edge of the leaves. The leaf can have many of these yellowish or red galls, which are hairy inside. The mite can also form an erineum on the underside of a leaf with reddish, violet or white hairs with swollen tips. The galls have been found on many different species of hawthorn, including, ''C. coccinoides'', ''C. l ...
