The journal will publish principally Finnish entomological investigations on ecology, faunistics, behavior and systematics of insects and other terrestrial arthropods.

Mites pose a serious problem to plants worldwide, attacking crops and spreading disease. When mites damage crops of economic importance the impacts can be felt globally. Mites are among the most diverse and successful of invertebrates, with over 45,000 described species, with many more thousands to be discovered. They are responsible for a significant portion of the losses of crops for food, fibre, industry and other purposes, and require expensive and often controversial pest control measures. Understanding these mites is vital for entomologists, pest researchers, agronomists and food producers. Knowledge of mite pests helps to inform control strategies and optimize the production of economic plants and the agrarian economy. This encyclopedia provides a thorough coverage of the mites and the problems they cause to crops, yet it is easily searchable, organised by mite species and subdivided into helpful headings. It takes a worldwide view of the issue of mites injurious to economic plants, describing mites prevalent in different regions and discussing control methods appropriate in different environments. This book provides an encyclopaedic reference to the major mites, described by family in terms of their internal and external morphology, bio-ecology and family systematics. Methods of mite collection and laboratory study is described, as well as species diagnostic characteristics, worldwide distribution, host plants, identification by the type of damage they cause and control strategies, including chemical and biological intervention and integrated pest management measures. Mites of the following families are included: (Eriophyoidea, Tarsonemidae, Tuckerellidae, Tenuipalpidae, Tetranychidae, Acaridae, Penthaleidae). Mites of Economic Plants is an important resource for students of entomology and crop production, and as a thorough reference guide for researchers and field workers involved with mites, crop damage and food production.

This book first reviews the biology of Dytiscidae or water beetles, including life history and ecology. It then defines and keys adults & larvae (when known) of dytiscid fauna of Canada, the United States, and for some taxa also northern Mexico. The focus is on the fauna of Canada & Alaska, and adults of the 276 species known from this region are treated in detail. For each Canadian-Alaskan species, the following information is presented: nomenclature & synonymy; selected references; description, including illustrations of taxonomically important characteristics; comments on classification or variation; notes on ecology; and description of the species range, accompanied by a map of collection records. Checklists of the dytiscid fauna of Canada/Alaska are also presented, with the distribution of the species recorded by province/territory and Canadian ecozone. Includes systematic index.

Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. The World Catalogue of Insects series is an initiative compiling worldscale, authoritative catalogues of monophyletic insect taxa. Each volume in the series contains standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume five focuses on Tortricidae (Lepidoptera).

The first volume to appear in a new series of handbooks deals with the ca. 115 families of Diptera (flies and Mosquitoes) known or suspected to occur in the islands of Malesia. Diptera constitute one of the larger orders of insects, and are generally considered to be a taxonomically difficult group, even at the family level. They include various economically important groups, some for example acting as vectors of diseases in man and cattle, while others are beneficial in pest control by virtue of their parasitic of predatory habits. In this work, each family is characterised, and a key using characters of the adult insects enables identification to family level. In addition, information is provided on biology, ecology, economic importance, distribution, and status of taxonomic knowledge, with key references to each family. It further includes an introduction to the higher classification, general biology and morphology, with an extensive glossary. The text is illustrated with more than 200 line drawings. An exhaustive and up-to-date list of references facilitates access to the pertinent literature. For this book, the author has worked together with world specialists of the respective families. The Families of Diptera of the Malay Archipelago will be an indispensable tool for all those working in the fields of ecology, systematic biology, and conservation, as well as applied biology.
