Louse is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research.
Bookworm is a general name for any insect that is said to bore through books.
Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are over 1,800 species described.
Psocoptera are a paraphyletic group of insects that are commonly known as booklice, barklice or barkflies. The name Psocoptera has been replaced with Psocodea in recent literature, with the inclusion of the former order Phthiraptera into Psocodea.
The wheat weevil, also known as the grain weevil or granary weevil, is an insect that feeds on cereal grains, and is a common pest in many places. It can cause significant damage to harvested stored grains and may drastically decrease crop yields. The females lay many eggs and the larvae eat the inside of the grain kernels.
Psocomorpha is a suborder of barklice, booklice, and parasitic lice in the order Psocodea. There are more than 20 families and 5,300 described species in Psocomorpha.
Troctomorpha is one of the three major suborders of Psocodea (barklice, booklice, and parasitic lice), alongside Psocomorpha and Trogiomorpha. There are more than 30 families and 5,800 described species in Troctomorpha. The order includes parasitic lice, which are most closely related to the booklice family Liposcelididae.
Oryzaephilus surinamensis, the sawtoothed grain beetle, is a beetle in the superfamily Cucujoidea. It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco. The species's binomial name, meaning "rice-lover from Suriname," was coined by Carl Linnaeus, who received specimens of the beetle from Surinam. It is also known as the malt beetle and may be referenced in the poem This Is The House That Jack Built in the line "....the rat that ate the malt that lay in the house that Jack built" the malt referenced may not be actual malted grain but a sawtoothed grain beetle.
The foreign grain beetle is a species of beetle in the family Silvanidae. It is related to the sawtoothed grain beetle.
Compsocidae is a family of Psocodea belonging to the suborder Troctomorpha. The family comprises two extant species in two genera, both found in Mesoamerica. Compsocus elegans is found in Mexico and Central America, while Electrentomopsis variegata is found in Mexico. The antennae of each species have 13 or 14 segments. Two extinct genera, Burmacompsocus and Paraelectrentomopsis are known from the Cenomanian aged Burmese amber of Myanmar.
Liposcelididae is a family of booklice of the order Psocodea, belonging to the suborder Troctomorpha. Members of this family are small and flattened, and often wingless. Mesothorax and metathorax fused in wingless forms.
Ectopsocidae is a family of Psocodea belonging to the suborder Psocomorpha. The family includes fewer than 200 species, most of them in the genus Ectopsocus.
Home-stored product entomology is the study of insects which infest foodstuffs stored in the home. It deals with the prevention, detection and eradication of the pests. The five major categories of insects considered in this article are flour beetles, the drugstore beetle, the sawtoothed grain beetle, the Indianmeal moth and fruit flies.
Psocodea is a taxonomic group of insects comprising the bark lice, book lice and parasitic lice. It was formerly considered a superorder, but is now generally considered by entomologists as an order. Despite the greatly differing appearance of parasitic lice (Phthiraptera), they are believed to have evolved from within the former order Psocoptera, which contained the bark lice and book lice, now found to be paraphyletic. They are often regarded as the most primitive of the hemipteroids. Psocodea contains around 11,000 species, divided among four suborders and more than 70 families. They range in size from 1–10 millimetres (0.04–0.4 in) in length.
The Angoumois grain moth is a species of the Gelechiidae moth family, commonly referred to as the "rice grain moth". It is most abundant in the temperate or tropical climates of India, China, South Africa, Indonesia, Malaysia, Japan, Egypt and Nigeria, with its location of origin being currently unknown. It is most commonly associated as a pest of field and stored cereal grains as they burrow within the kernel grains of crop plants, rendering them unusable for human consumption. By laying eggs between the grains themselves and hatching at a later time, often during the processing, transportation or storage stages, the moth can be transported to households or countries presently free of Angoumois grain moth infestations. Thus, constant protection against the Angoumois grain moth is required for grain up till the time of consumption.
The maize weevil, known in the United States as the greater rice weevil, is a species of beetle in the family Curculionidae. It can be found in numerous tropical areas around the world, and in the United States, and is a major pest of maize. This species attacks both standing crops and stored cereal products, including wheat, rice, sorghum, oats, barley, rye, buckwheat, peas, and cottonseed. The maize weevil also infests other types of stored, processed cereal products such as pasta, cassava, and various coarse, milled grains. It has even been known to attack fruit while in storage, such as apples.
Liposcelis bostrychophila is a species of booklouse in the family Liposcelididae. It is known nearly worldwide as a common pest of stored products. It is especially prevalent in cereals. In 2019 it was identified as a predator of mosquito eggs in a FAO/IAEA Insect Pest Control Laboratory which developed sterile males.
Grain damage is any degradation in the quality of grain. In the current grain trade, this damage can affect price, feed quality, food product quality, and susceptibility to pest contamination. Between the field and the end use, grain may go through any number of handling operations which can each contribute to grain damage. For example, grain might encounter free fall, conveyors, spouts, grain throwers, elevators, hoppers, dryers, and many more. Overall, these handling methods can be evaluated as to what effect they have on the grain. Damaged grain can often be characterized by the extent to which it reduces storage time. For example, cracked or broken kernels are more susceptible to insect or bacteria as well as chemical degradation. The damage to the actual grain is only one example of losses incurred after harvest. In order to quantify grain damage, one must also understand grain quality. Grain quality is a very broad term and can relate to many topics such as foreign material, chemical compositions, mechanical damage, insect infestations, and many more. These references to quality are highly dependent on the end use of the grain. Certain types of damage may be acceptable to specific industries, whereas others cannot use grain with these issues.
Integrated pest management in museums, libraries, archives and private collections is the practice of monitoring and managing pest and environmental information with pest control methods to prevent pest damage to collections and cultural property. Preserving cultural property is the ultimate goal for these institutions. The pests come in many different forms: insects, mites, rodents, bats, birds, and fungi and the two most common types are insects and fungi. It is widely recommended that every museum have some form of pest control in place and monitoring system to protect their collection and that museums review their storage and museum facilities to determine how to best control and prevent pest infestations while utilizing an Integrated Pest Management plan.
Manicapsocidae is a family of Psocodea. It contains 8 extant species in 4 genera, with most of the species being found in the Neotropics, with one species in the Afrotropics. The extinct family Electrentomidae has been suggested to be a synonym of this family, though this has been considered premature by other scholars in the absence of cladistic analysis. Confirmed fossil species of the family are nearly as numerous as living ones, extending back to the Mid-Cretaceous.
