Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae)

Psocids belonging to the families Liposcelididae and Trogiidae are responsible for most of the psocid-related problems associated with stored products in the U.S. Lepinotus reticulatus belongs to the family Trogiidae, whereas psocids of the genus Liposcelis belong to the family Liposcelididae. L. reticulatus goes through four nymphal stages during its development from egg to adult; at 32.5°C (90.5°F) development is completed in 23 days (Opit et al. 2008a). L. reticulatus does not survive at relative humidities of 55% or less (Opit et al. 2008a). On oats, L. reticulatus population can increase 35-fold in a month, and on rice, barley, milo, and wheat it can increase 27-fold (Opit et al. 2008b). Literature Cited Opit, G.P. and J.E.
