Dermestes ater is a species of beetle in the family Dermestidae, the skin beetles. It is known commonly as the black larder beetle or incinerator beetle (not to be confused with Dermestes haemorrhoidalis , the African larder beetle, also sometimes referred to as the black larder beetle). [1] It is native to North America, but today it is found nearly worldwide. Like several other dermestid beetles, this species is a common pest of stored products. [1]

Description

The adult beetle is about 7 to 9 millimeters long. It has black or brown elytra and a coating of yellowish hairs. The male can be distinguished from the female by a row of bristles along the abdomen. The larva has long dark bristles. Its body is white except for its head capsule, dorsal plates and urogomphi, which darken in color to black, brown, or reddish as it grows. Adults reach a maximum length of about 14 mm and larvae of about 14 to 17 mm.

Adults of Dermestes ater resemble D. haemorrhoidalis and D. peruvianus but differ in several ways. In D. ater, the first visible sternite bear impressed lines parallel to the lateral margin that are angled inwards towards the base, therefore their end next to the metasternal hind margin is at some distance from the edge; while on D. haemorrhoidalis and D. peruvianus these lines are parallel to the side margin throughout their length. Dermestes ater further differs from the two other species in having a symmetrical pattern of light and dark pubescence on all abdominal sternites. The dark pubescence being near the side edges. The dark pubescence may be barely visible so these areas may appear glabrous next to the lighter (grey) pubescence. [2] Larvae of D. ater can be distinguished from close relatives in having their urogomphi backwardly directed, but appearing nearly straight in side view. Each tibia bears a short stout spine on dorsal apex of posterior face. Abdominal tergites 4-9 without retrorse tubercles but instead each has a row of about 30 short erect setae immediately posterior to anterior transverse ridge (larvae of other species have much fewer than 30). Head without frontal tubercles. [3]

Life cycle

The female lays 1 to 25 eggs at a time. They are whitish and about 2 millimeters long. The eggs hatch in a few days, depending on temperature. Larval development also depends on temperature, as well as humidity and food availability. Each larva may proceed through six to nine instars, taking 19 to 50 days to grow to maximum size. It then pupates for several days. The adult lives for around 169 days, depending on temperature. [1]

Economic and scientific importance

The beetle attacks many types of stored food and other products. It has been found in cheese, dried fish, leather, copra, silk, wool, milk powder, incinerated waste, [1] hog bristles, dried mushrooms, cacao, and ginger. [4]

It is an occasional predator, feeding on live insects; it is a pest of the sericulture industry because it preys on silkworm pupae, damaging the silk cocoons in the process. [5] It also feeds on housefly (Musca domestica) larvae and pupae in places where both insects congregate, such as poultry houses. [6] The adult may cannibalize larvae and pupae of its own species, and the larvae may eat each other and the eggs. [1] It is also a scavenger of dead animals. [4] It is a pest of museum collections, such as dried insects. [1] It has been found living in and consuming human corpses, so it may play a role in forensic entomology. [7]

The beetle carries several parasites including chicken tapeworms, and are found inhabiting chicken coops where they can spread the parasites to the birds. [8]

<span class="mw-page-title-main">Beetle</span> Order of insects

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.

<span class="mw-page-title-main">Khapra beetle</span> Species of insect

The khapra beetle, also called cabinet beetle, which originated in South Asia, is one of the world's most destructive pests of grain products and seeds. It is considered one of the 100 worst invasive species in the world. Infestations are difficult to control because of the insect's ability to survive without food for long periods, its preference for dry conditions and low-moisture food, and its resistance to many insecticides. There is a federal quarantine restricting the importation of rice into the U.S. from countries with known infestations of the beetle. Khapra beetle infestation can spoil otherwise valuable trade goods and threaten significant economic losses if introduced to a new area. Handling or consuming contaminated grain and seed products can lead to health issues such as skin irritation and gastrointestinal distress.

<i>Anthrenocerus australis</i> Species of beetle

Anthrenocerus australis is a species of beetle belonging to the Dermestidae family. It is commonly known as the Australian carpet beetle and is one of the most researched of the thirty-one species in the Anthrenocerus genus. This is generally attributed to its prevalence throughout Australia and New Zealand and the negative economic and agricultural impact it has as a pest. It is the larvae that causes damage to products, not the adult beetle. The total life cycle of this insect is around three years, most of which is spent as a larva. Once the beetle reaches maturity, it only lives for between two and six weeks.
