Pterotermes is a monotypic genus of termites in the family Kalotermitidae. Pterotermes occidentis is the single species in the genus. This termite lives in the extremely dry conditions found in the Sonoran Desert in southwestern United States, Baja California and Mexico. It feeds on dry wood and lives entirely within a single piece of timber. [1]

Description

Pterotermes occidentis is the largest drywood termite found in the deserts of southwestern USA. It is a primitive species of termite and the castes are indistinct. The eggs hatch into nymphs which grow into "pseudergates", which act as workers before developing into either soldiers or winged reproductives. The winged reproductives have large black compound eyes with white eyespots immediately above. The thorax and abdomen are orange and the pronotum is relatively flat and does not curve downwards at the side. The soldiers have a rounded, flat-topped head, large wingbuds, and a massive pronotum with a V-shaped notch at the front which distinguishes them from other species found in the region. They are also unusual in having prominent eyespots. [1]

Blue palo verde with dead wood suitable for colonisation

After a mating flight, individual reproductives walk across the substrate, searching for a suitable hole or crevice in dry dead wood. They do not bore a hole, but may enlarge an existing one. They may be later joined in the hole by another individual, and one to three days later, seal the entrance with a faecal plug. [2] colony founding is a very slow process; after the nest has been in existence for a year, their offspring may number somewhere between zero and twelve. The colony expands by the creation of a haphazard collection of galleries. These are generally kept clean, but "kick holes" are made to the exterior in places through which faecal pellets are pushed. The holes are then resealed, and abandoned chambers may be filled with faecal pellets and the desiccated corpses of any colony members that have died. These termites are intolerant of moisture, feed only on dry wood and derive the water they need from their diet. Flights of reproductives occur in July and August. [1]

P. occidentis feeds mainly in dead branches of Parkinsonia florida , the blue palo verde, while Marginitermes hubbardi , another species of drywood termite present in the Sonoran Desert, mainly feeds on the skeletal remains of saguaro. [3] Dry timber being a very difficult food from which to extract nourishment, the termites accumulate an array of about forty symbiotic microorganisms in their gut to help them digest it. All colonies of P. occidentis have this wide range of gut symbionts, suggesting that the diversity is necessary for colony survival. [4]

<span class="mw-page-title-main">Termite</span> Social insects related to cockroaches

Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are distinguished by their moniliform antennae and the soft-bodied and typically unpigmented worker caste for which they have been colloquially termed "white ants"; however, they are not ants to which they are distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.

<span class="mw-page-title-main">Blattodea</span> Order of insects that includes cockroaches and termites

Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.

<i>Reticulitermes flavipes</i> Species of insect found in North America

Reticulitermes flavipes, the eastern subterranean termite, is the most common termite found in North America. These termites are the most economically important wood destroying insects in the United States and are classified as pests. They feed on cellulose material such as the structural wood in buildings, wooden fixtures, paper, books, and cotton. A mature colony can range from 20,000 workers to as high as 5 million workers and the primary queen of the colony lays 5,000 to 10,000 eggs per year to add to this total.

<i>Zootermopsis angusticollis</i> Species of termite

Zootermopsis angusticollis is a species of termite (Isoptera) in the family Archotermopsidae, a group known as the dampwood termites, or the rottenwood termites. As their name suggests, the dampwood termites can only survive by living off of wood that contains high amounts of moisture. They are found along the wet environments of the Pacific coast of North America. Most are found in the states of California, Oregon, Washington, Idaho, Western Nevada and in southern British Columbia. Termites are well known to be destroyers of wood, and although the dampwood termites can cause some damage, they are not as notoriously known to cause as much damage to buildings as the drywood termites. They occasionally have been carried to other parts of the country through wood shipments, but have not been able to become established in these areas due to undesirable environmental conditions.
