Manual for identification of quarantine and other important pests of raw materials, stored products, and seedBy Mordkovich Ya.B., Sokolov E.A.
Kolos, Moscow, 384 pp., 1999
[In Russian; original title: Spravochnik-opredelitel' karantinnykh i drugikh opasnykh vreditelei syr'ya, produktov zapasa i posevnogo materiala]
The title is rather deceptive, as the illustrated keys cover only two insect orders (no mites, etc.), i.e. 400+ beetle species and ~160 spp. of lepidopteran larvae associated with stored products and seed worldwide, incl. many obscure species of no commercial relevance at all. Despite the outdated taxonomy, the book is helpful in providing valuable illustrations borrowed from authoritative sources, distribution and habitat/product data not found online elsewhere, and info on many beetle spp.

This manual concerns itself with insects and related organisms in forests and woodlands of North America, west of the 100th Meridian and north of Mexico. ("Eastern Forest Insects," by Whiteford L. Baker (1972) covers the area east of the 100th Meridian.) The intended primary users are practicing foresters and others responsible for preventing or minimizing insect-caused damage to forests and wood products. Thus, major purposes of the manual are to facilitate recognition of insects and their damage and to provide needed information for determining a course of action. The manual should also be useful to students of forestry and entomology, professional entomologists, extension specialists, forestry technicians, forest owners, forest recreationists, teachers, and others.
