A new species Attagenus (s. str.) namibicus sp. nov. from Namibia is described, illustrated and compared with similar looking species. A list of all species from Namibia which belong to the genus Attagenus is furthermore provided. INTRODUCTION The genus Attagenus Latreille, 1802 is one of about 60 genera established within the beetle family Dermestidae. This genus includes of about 250 different species respectively subspecies worldwide (Háva 2015), 11 of them have still been recorded from the Republic of Namibia (Háva 2005, Herrmann & Háva 2007, Háva & Kadej 2008, Herrmann & Háva 2014, Háva, Herrmann & Kadej 2015, Herrmann & Háva 2016). In the present paper we describe a new species of this genus which was detected during an examination of some unidentified dermestids deposited in the collection of the Royal Belgian Institute of Natural Sciences (ISNB). MATERIAL AND METHODS The dried specimens were weakened for 5 days in a solution of 1% pepsin in diluted hydrochloric acid to free them roughly from protein tissues and to make the extremities of the body moveable, again. The abdomen was disconnected from the body and glued upside- down onto the same cardboard plate, just behind the beetle. -

PESTS of STORED PRODUCTS a 'Pest of Stored Products' Can Refer To
PESTS OF STORED PRODUCTS A ‘pest of stored products’ can refer to any organism that infests and damages stored food, books and documents, fabrics, leather, carpets, and any other dried or preserved item that is not used shortly after it is delivered to a location, or moved regularly. Technically, these pests can include microorganisms such as fungi and bacteria, arthropods such as insects and mites, and vertebrates such as rodents and birds. Stored product pests are responsible for the loss of millions of dollars every year in contaminated products, as well as destruction of important documents and heritage artifacts in homes, offices and museums. Many of these pests are brought indoors in items that were infested when purchased. Others originate indoors when susceptible items are stored under poor storage conditions, or when stray individual pests gain access to them. Storage pests often go unnoticed because they infest items that are not regularly used and they may be very small in size. Infestations are noticed when the pests emerge from storage, to disperse or sometimes as a result of crowding or after having exhausted a particular food source, and search for new sources of food and harborage. Unexplained occurrences of minute moths and beetles flying in large numbers near stored items, or crawling over countertops, walls and ceilings, powdery residues below and surrounding stored items, and stale odors in pantries and closets can all indicate a possible storage pest infestation. Infestations in stored whole grains or beans can also be detected when these are soaked in water, and hollowed out seeds rise to the surface, along with the adult stages of the pests, and other debris. -

PMI i.e. Post- Mortem Interval also known as Time Since Death is most important enigma, which has always successfully bedazzled an investigator or a forensic pathologist to determine the correct sequence in which the crime took place. The dead body does not always follow a strict rule towards the different stages of decomposition in regards to the time interval. The temperature, mode of death, food ingested, BMI i.e. Body Mass Index and other environmental factors also influence, the stages observed at different times and often in such scenario forensic entomology is referenced but sometimes, it is not possible to find blow flies or maggots after certain time period. In present study, the main focus is on establishing the post mortem interval through succession of hister sp. and other ground beetles in not only at different stages of decomposition also in different habitats and environmental factors on carcasses found on surfaces but also from exhume bodies. -

Attagenus (Attagenus) maculatus sp. n. from Greece and Bulgaria is described, illustrated and compared to related species. Key words: entomology, taxonomy, new species, Coleoptera, Dermestidae, Attagenini, Attagenus, Greece, Bulgaria INTRODUCTION The dermestid genus Attagenus LATREILLE, 1802 contains worldwide about 195 species and subspecies (HÁVA 2003, 2006), but only 8 species from Greece and 5 species from Bulgaria (KRAATZ 1858, MROCZKOWSKI 1965, 1968, ANGELOV 1988). While studying material from collections listed below, I found a new species of the genus and subgenus Attagenus LATREILLE, 1802 from Greece and Bulgaria. It is surprising that this conspicuous species remained for so long unknown, in spite of large collections made in the Balkans.

Black Carpet Beetle, Attagenus Unicolor (Brahm) (Insecta: Coleoptera: Dermestidae)1 Jerry E

Gahlhoff2 Introduction Adults The black carpet beetle, Attagenus unicolor (Brahm), is the Dark brown or black adults are oval shaped and 1/8 to 3/16 most common and most destructive of the five important inch in length. This stage feeds outdoors on pollen and species of carpet beetles in the United States. It damages nectar, migrating indoors to lay eggs about a week after household products containing keratin, a principal protein emergence. Adults can live nine months to three years found in animal hair and feathers. Plant products such as depending on food availability and other environmental cereals and grains, as well as synthetic fabrics not derived factors. from animal matter, may also be attacked. Dried insect specimens, such as those found in insect collections, are also devoured. Distribution The black carpet beetle is found throughout the United States, Canada, and Mexico. It is believed that this pest may have been imported to the United States in the early 19th century from Europe where it is not considered a major pest. Humidity plays a large role for development of carpet beetles. In the southern states, high humidity may often cause the black carpet beetle’s eggs to become moldy while in the northern states lower humidity is usually favorable for a successful egg hatch.

Occurrence, Ecological Function and Medical Importance of Dermestid Beetle Hastisetae
Occurrence, ecological function and medical importance of dermestid beetle hastisetae Enrico Ruzzier1, Marcin Kadej2 and Andrea Battisti1 1 Department of Agronomy, Food, Natural Resources, Animals and the Environment (DAFNAE), Università degli Studi di Padova, Padova, Italy 2 Department of Invertebrate Biology, Evolution and Conservation, University of Wrocªaw, Wrocªaw, Poland ABSTRACT Hastisetae are a specific group of detachable setae characterizing the larvae of Megatom- inae (Coleoptera: Dermestidae), commonly known as carpet and khapra beetles. These setae are located on both thoracic and abdominal tergites and they are the primary defense of the larva against invertebrate predators. According to previous studies, the main purpose of hastisetae is to work as a mechanical obstacle, but they are also capable to block and kill a predator. Hastisetae, single or aggregate, function as an extremely efficient mechanical trap, based on an entangling mechanism of cuticular structures (spines and hairs) and body appendages (antennae, legs and mouthparts). It is believed that this defensive system evolved primarily to contrast predation by invertebrates, however it has been observed that hastisetae may affect vertebrates as well. Although information on the impacts of vertebrate predators of the beetles is lacking, hastisetae have been shown to be a possible threat for human health as an important contaminant of stored products (food and fabric), work and living environment. Review of past and recent literature on dermestid larvae has revealed that despite these structures indicated as one of the distinctive characters in species identification, very little is known about their ultrastructure, evolution and mechanism of action. In the present work, we will provide the state of knowledge on hastisetae in Dermestidae and we will present and Submitted 1 July 2019 discuss future research perspectives intended to bridge the existing knowledge gaps.
