Pyemotes herfsi, also known as the oak leaf gall mite or itch mite, is an ectoparasitic mite identified in Europe and subsequently found in India, Asia, and the United States. The mite parasitizes a variety of insect hosts and bites humans, causing red, itchy, and painful wheals (welts). The mites are barely visible, measuring about 0.2–0.8 ...
Aceria mackiei, previously Eriophyes mackiei, the live oak erineum mite, is an abundant eriophyoid mite that produces leaf-blister galls on coast live oak, interior live oak, huckleberry oak, and canyon live oak. [1] This mite's ability to induce galls in oaks of both the black oak group and the intermediate oak group is unique. [1]
The microscopic mite Lorryia formosa (). The mites are not a defined taxon, but is used for two distinct groups of arachnids, the Acariformes and the Parasitiformes.The phylogeny of the Acari has been relatively little studied, but molecular information from ribosomal DNA is being extensively used to understand relationships between groups.
Zaborski further found that the mites were ectoparasites whose numbers had increased while feeding on the brood's eggs. [ 9 ] The mites usually feed on oak leaf gall midge ( Polystepha pilulae ) larvae and other insects, but, as Zaborski found, also parasitize periodical cicada eggs when those are available.
Hundreds of thousands of the tiny wind-soaring and itch-inducing critters can fall from trees every day and are packed with a venom that can paralyze prey 166,000 times their size.
Only young developing leaves are susceptible to colonisation by E. alphitoides.It only induces necrosis when infection occurs very early during leaf development. Because the pathogen develops late in spring, after the first leaves of oak seedlings have developed, it is more prevalent on the second and third flushes of leaves that develop in July and August.
Quercus ilicifolia, commonly known as bear oak or scrub oak, is a small shrubby oak native to the Eastern United States and, less commonly, in southeastern Canada. Its range in the United States extends from Maine to North Carolina , with reports of a few populations north of the international frontier in Ontario . [ 3 ]
Eriophyes tiliae is a mite that forms the lime nail gall or bugle gall. [2] It develops in a chemically induced gall; an erect, oblique or curved distortion rising up from the upper surface of the leaves of the lime (linden) trees (genus Tilia), such as the large-leaved lime tree Tilia platyphyllos, the common lime tree Tilia × europaea, etc.
