Petrobia is a genus in Tetranychidae (spider mites), containing 34 described species. [1] [2] [3] [4] It includes some pest species.

Description

Petrobia mites can be recognised by their reddish-brown cuticle, dark body contents and the first leg pair being very long. Each leg ends in pad-like claws and a hooked (uncinate) empodium with more than 1 pair of tenent hairs. The prodorsum of the body has three pairs of setae (ve, sci, sce) and there are no prominent lobes over the gnathosoma. The paranal setae (h2-3) are in a ventral position. [5]

The genus is usually divided into three subgenera: Mesotetranychus, Petrobia and Tetranychina (sometimes one or more of these are considered separate genera). Mesotetranychus has simple peritremes whereas Petrobia has anastomosing peritremes. Tetranychina usually has long dorsal setae on small tubercles (other subgenera sometimes have tubercles as well, but their dorsal setae are short). [6]

Reproduction

Species of Petrobia may reproduce either sexually (e.g. P. harti) or asexually (e.g. P. latens). [7] [8]

In P. harti, males make up 10% or less of field populations. Eggs are laid on the ventral surfaces of host plant leaves. [7]

Petrobia latens, on the other hand, has only female individuals. Females lay their eggs parthenogenetically on soil and under stones. [8]

Pests

Several Petrobia species are polyphagous plant pests, meaning they attack a wide range of plants: [5]

<i>Tetranychus urticae</i> Species of mite

Tetranychus urticae is a species of plant-feeding mite generally considered to be a pest. It is the most widely known member of the family Tetranychidae or spider mites. Its genome was fully sequenced in 2011, and was the first genome sequence from any chelicerate.

<span class="mw-page-title-main">Spider mite</span> Family of arthropods

Spider mites are members of the Tetranychidae family, which includes about 1,200 species. They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants, where they may spin protective silk webs, and can cause damage by puncturing the plant cells to feed. Spider mites are known to feed on several hundred species of plants.

<span class="mw-page-title-main">Acariformes</span> Superorder of mite

The Acariformes, also known as the Actinotrichida, are the more diverse of the two superorders of mites. Over 32,000 described species are found in 351 families, with an estimated total of 440,000 to 929,000 species, including undescribed species.

<i>Raoiella indica</i> Species of mite

Raoiella indica, commonly known as the red palm mite, is a species of mite belonging to the family Tenuipalpidae. A pest of several species of palm in the Middle East and South East Asia, it is now becoming established throughout the Caribbean. The invasion of this species is the biggest mite explosion ever observed in the Americas.

The Laelapidae are a family of mites in the order Mesostigmata. The family is also referred to in the literature as Laelaptidae, which may be the correct spelling.

<i>Bryobia</i> Genus of mites

Bryobia is a genus of mites in the spider mite family, Tetranychidae. The taxonomy of the genus is difficult. The genus has been revised several times. It is difficult to distinguish these tiny species from each other on the basis of morphological characters, and there is little agreement on which characteristics are of importance. Also, species can be variable in morphology. Over 130 species have been described, but many of the names are likely synonyms.
