Beetles are insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
Mealworms are the larval form of the yellow mealworm beetle, Tenebrio molitor, a species of darkling beetle. Like all holometabolic insects, they go through four life stages: egg, larva, pupa, and adult. Larvae typically measure about 2.5 centimetres (0.98 in) or more, whereas adults are generally 1.25 to 1.8 centimetres in length.
Darkling beetle is the common name for members of the beetle family Tenebrionidae. The number of species in the Tenebrionidae is estimated at more than 20,000 and the family is cosmopolitan in distribution.
Pest control is the regulation or management of a species defined as a pest; such as any animal, plant or fungus that impacts adversely on human activities or environment. The human response depends on the importance of the damage done and will range from tolerance, through deterrence and management, to attempts to completely eradicate the pest. Pest control measures may be performed as part of an integrated pest management strategy.
Pearl millet is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity, and suggested area of domestication, for the crop is in the Sahel zone of West Africa. Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BC. 2023 is the International Year of Millets, declared by the United Nations General Assembly in 2021.
The Tenebrionoidea are a very large and diverse superfamily of beetles. It generally corresponds to the Heteromera of earlier authors.
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily.
Tenebrio obscurus, or the dark mealworm beetle, is a species of darkling beetle whose larvae are known as mini mealworms. These insects should not be confused with younger mealworms or with the confused flour beetle.
Hydnoroideae is a subfamily of parasitic flowering plants in the order Piperales. Traditionally, and as recently as the APG III system it given family rank under the name Hydnoraceae. It is now submerged in the Aristolochiaceae. It contains two genera, Hydnora and Prosopanche:
A trap crop is a plant that attracts agricultural pests, usually insects, away from nearby crops. This form of companion planting can save the main crop from decimation by pests without the use of pesticides.[1] A trap crop is used for attracting the insect and pests away from the field.[1] Many trap crops have successfully diverted pests from focal crops in small scale greenhouse, garden and field experiments; a small portion of these plants have been shown to reduce pest damage at larger commercial scales. A common explanation for reported trap cropping failures, is that attractive trap plants only protect nearby plants if the insects do not move back into the main crop. In a review of 100 trap cropping examples in 2006, only 10 trap crops were classified as successful at a commercial scale, and in all successful cases, trap cropping was supplemented with management practices that specifically limited insect dispersal from the trap crop back into the main crop.
Eleodes is a genus of darkling beetles, in the family Tenebrionidae. They are endemic to western North America ranging from southern Canada to central Mexico with many species found along the Mexico-United States border. Some species have been introduced to Colombia. The name pinacate is Mexican Spanish, derived from the Nahuatl (Aztec) name for the insect, pinacatl, which translates as "black beetle."
Hydnora africana is an achlorophyllous plant in the subfamily Hydnoroideae, native to southern Africa that is parasitic on the roots of members of the family Euphorbiaceae. It is also called jakkalskos or jackal food. The specific epithet africana means to be from Africa. Molecular data has suggested that Hydnoroideae is a "basal angiosperm" solidifying its place among the more primitive flowering plants. Hydnoraceae are the only angiosperms known to have no leaves or scales and are considered obligate parasites, completely dependent on their hosts to survive. The plant grows underground, except for a fleshy flower that emerges above ground and emits an odour of faeces to attract its natural pollinators, dung beetles and carrion beetles. The vegetative body of the plants has been reduced to only consisting of roots and flowers. The flowers act as temporary traps, retaining the beetles that enter long enough for them to pick up pollen.
Eleodes osculans, the wooly darkling beetle or woolly ground beetle, is a common insect in coastal southern and central California in wooded areas or chaparral, and in Baja California. As a stink beetle of genus Eleodes, its easily observed defensive posture is to raise its hind end and secrete an unpleasant odor. E. osculans has a length of 12-16 mm and is the only known darkling beetle species with reddish-brown hair covering most of its black exoskeleton. It is similar to Eleodes nigropilosa and Eleodes littoralis, which have darker hair.
Hydnora is a group of parasitic plants described as a genus in 1775. It is native to Africa, Madagascar, and the Arabian Peninsula. Hydnora pollinates through brood-site mimicry. This is a method of pollination in which the plant emits a smell that is attractive to insects, so that the plant can trap the insect and allow it to take pollen so that it can pollinate other Hydnora.
Toktokkies are various species of beetles that belong to the large Tenebrionidae family, also known as Darkling beetle. Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species that make distinct noises by tapping on the ground with the abdomen. The Tenebrionidae family to which these beetles belong is quite large, with almost 3,500 species inhabiting Southern Africa. Nearly 200 species of Toktokkies inhabit the Namibia and 20 have adapted to the extreme temperatures of the Namib Desert. The most common Toktokkies in the Namib Desert are the Fog Basking beetle and the button beetle or trench-digging beetle.
Asbolus verrucosus(LeConte, 1852), also known as the desert ironclad beetle or blue death feigning beetle, is a species of darkling beetle native to southwestern United States and northwestern Mexico, where it inhabits dry, sandy habitats such as the Sonoran and Mojave Deserts. It is highly adapted to hot environments and is omnivorous, consuming dead insects, fruits, lichen, and other plant matter. When threatened, the beetles are able to feign death. The species is becoming increasingly popular in the pet trade, due to their ease of care, hardiness, and longevity.
Physosterna cribripes, the desert toktokkie or woestyntoktokkie, is a flightless species of desert-dwelling darkling beetle or Tenebrionid found along the West coast of Namibia and Angola. This species has a body length of some 18.4 mm and a mass of 402 mg.
Hydnora visseri, the Visser's hydnora, is a subterranean holoparasitic plant, lacking leaves and roots, and is described from southwestern Namibia and northwestern South Africa and has the longest tepal lobes of all Hydnora species. The genus Hydnora is composed entirely of holoparasitic plants that attach to the root of their hosts and are restricted to Africa and southwestern Asia.
Palorus ratzeburgii, the small-eyed flour beetle, is a species of darkling beetle in the family Tenebrionidae.
Palorus is a genus of darkling beetles in the family Tenebrionidae. There are at least 4 described species in Palorus.
