Knowra Psocoptera Psocoptera Psocoptera is the traditional insect order comprising barklice and booklice. Modern classifications often treat it as a paraphyletic grouping within Psocodea because parasitic lice evolved from within it.
Psocodea : Psocodea is an insect order containing barklice, booklice, and parasitic lice. It is the broader order that includes the traditional Psocoptera grouping.
Incomplete metamorphosis : Incomplete metamorphosis is development through egg, nymph, and adult stages without a pupal stage. Psocopterans develop through nymphs that resemble smaller, wingless adults.
Stored-product pest : A stored-product pest is an organism that damages food or other materials kept in storage. Booklice can become nuisance pests in damp stores of food and paper goods.
Phthiraptera : Phthiraptera is the traditional order of parasitic lice that live on birds and mammals. Their inclusion in Psocodea makes traditional Psocoptera paraphyletic.
Paraphyly : Paraphyly describes a group containing a common ancestor and some, but not all, of its descendants. Psocoptera is often called paraphyletic because parasitic lice descend from within its lineage.
Molt : Molting is the shedding of an arthropod’s external cuticle as it grows. Nymphs must molt repeatedly before reaching the adult form.
Integrated pest management : Integrated pest management combines monitoring, prevention, and targeted control to limit pest damage. Reducing moisture and mold is often central to managing booklice indoors.
Amblycera : Amblycera is a suborder of chewing lice, many of which live on birds and mammals. It is one lineage of parasitic lice placed within Psocodea.
Insect : Insects are six-legged arthropods with bodies divided into head, thorax, and abdomen. Psocoptera belongs to this broader animal class.
Gregariousness : Gregariousness is the tendency of animals to gather in groups. Some barklice form aggregations and use shared silk coverings for protection.
