Technical Abstract: Previously regarded as minor nuisance pests, psocids belonging to the genus Liposcelis are now a major problem for effective protection of stored-products world-wide. In this review we examine the apparent biological and operational reasons behind this phenomenon and why conventional pest management seems to be failing. We also investigate what is known about the biology, behavior, and population dynamics of major pest species to ascertain their strengths, and perhaps find weaknesses, as a basis for a rational pest management strategy. We outline the contribution of molecular techniques to clarifying species identification and understanding genetic diversity. We discuss progress in sampling and trapping, and our understanding of spatial distribution of these pests as a foundation for developing management strategies. Effectiveness of various chemical treatments and the availability and potential of non-chemical control methods are also critically examined. Finally, we outline research gaps and suggest future directions for research.
