Brief Summary ( Anglèis )

fornì da EOL authors
The black carpet beetle, Attagenus unicolor, is a serious household pest, the most common and most destructive of the carpet beetles in North America and Mexico (the other species being the common carpet beetle, furniture carpet beetle, the varied carpet beetle, all in the dermestid family). Attagenus unicolor is thought to have been brought to the states from Europe in the 1800s. This insect is particularly common in areas with lower relative humidity, as their eggs are susceptible to molding in humid conditions. The name carpet beetle derives from the damage these pests have historically incurred on wool carpets, but they are trouble in a much more general sense than simply carpets. In the larval stage, Attagenus unicolor will damage any product containing keratin (furs, feathers, leather, wool, silk, dried meat, dander, hair). They also do great damage to man-made synthetic products when they are mixed in with natural products (e.g. wool-synthetic yarn blends) because they need to eat more in order to satisfy their nutritional needs. In addition, black carpet beetles attack plant products (grains and cereals), making them a kitchen pest as well as a general household pest. Their destructive eating habits are much feared in museums. This species lives up to 650 days as a larva, depending on conditions. Larvae are carrot shaped, may reach up to almost 13 mms, and are covered with bristles with a distinguishing tuft of long hair on the back segment. The adults, elongated dark beetles about 3-5mm long, live up to two months and feed on flower pollen.

Black carpet beetle ( Anglèis )

fornì da wikipedia EN

The black carpet beetle (Attagenus unicolor) is a 3–5-millimetre-long (0.12–0.20 in) beetle that can be a serious household pest. The larvae grow to 7 mm (0.28 in) in length, are reddish brown in colour and covered with bristles. The larval form feeds on natural fibres, damaging carpets, furniture and clothing.

Life cycle

Attagenus unicolor undergoes complete metamorphosis, which has four life stages: Egg, larvae, pupae and adult. Each stage looks different, and needs different amounts of time to reach the next stage.

Eggs are usually laid near or on a food source. If no food source can be found, the female will lay them in dark undisturbed locations where the larvae can feed on carpeting or clothing. They will also lay eggs on or near dog food or other pet food. Eggs take anywhere from 5 to 20 days to hatch depending on the conditions, such as temperature and humidity.

Larvae are about 1 mm (0.039 in) in size when they hatch from the egg. They grow fairly quickly depending on the food source availability and protein found in the food itself. Larvae moult about 10 to 15 times, or more depending on conditions. Sometimes if food is scarce they will retro-moult with the larvae moulting into a lower instar. They can do this multiple times, if they are large enough.

The larval stage is the longest and most destructive stage; they can remain as larvae for up to 3 years, although it does not typically take longer than 3 months to go through the larval stage if food and conditions are good. Larvae pupate in undisturbed locations, far away from the food source so that they aren't cannibalized.

Pupae are cream white but quickly turn yellow and darken with age. They do not eat in this stage nor move. They transform into the beetles in about 8 to 20 days, depending on the conditions. The beetle may stay in the shedded pupae case for an additional day or two.

Beetles start out white but darken with age. They typically do not eat, although they will sometimes eat flower pollen in the wild, but not indoors. Adults live for a few weeks, just long enough to mate and lay more eggs. They are eventually black in colour, hence the name Black Carpet Beetle. Females are capable of laying 50 to 100 eggs.

The whole life cycle under ideal conditions takes about 4 to 5 months, or less if given protein-rich food, such as pet food. The adult females will lay more eggs if water is present in small amounts.

Selon BioLib (5 juin 2021)[2] :

  • Attagenus unicolor japonicus Reitter, 1877
  • Attagenus unicolor simulans Solsky, 1876
  • Attagenus unicolor unicolor (Brahm, 1791)

Distribution

Attagenus unicolor a une aire de répartition cosmopolite[3]. Cet insecte aurait été importé aux États-Unis en provenance d'Europe au début du xixe siècle[4].

Ковровый кожеед, или ковровый жук (лат. Attagenus unicolor) — вид жесткокрылых насекомых из подсемейства Dermestinae внутри семейства кожеедов (Dermestidae). Распространён в Европе, Азии, а также Канаде, США, Мексике[1][2] и Австралии[3]. Подвид A. u. japonicus распространён в Хабаровском и Приморском краях, в Амурской области, Японии, Корейском полуострове, северо-восточном Китае и Монголии[4].

В природных условиях встречается заселяя гнёзда птиц, живущих в дуплах деревьев.

Описание

Тело жука овальное длиной 2,5—5,5 мм. Окрас равномерный от светло-коричневого до чёрного. Ковровый кожеед — довольно распространённый синантропный вид кожеедов. Живёт в том числе в домах, питаясь органическими остатками в домашней пыли.

Хозяйственное значение

Является серьёзным вредителем кожи, меха и шерсти, а также изделий из них. Также может повреждать перья, шёлк, зерно, муку и другие растительные продукты. Вред наносят только личинки.
