A work on the songs of the grasshoppers and crickets of Western Europe, with over 1600 oscillograms taken from the 174 species and subspecies covered, as well as 11 confusibles from other orders (cicadas, amphibians and birds).
Most of the 170 species of grasshoppers and crickets included in this book can be identified instantly by their songs – and often more reliably than from their appearance. Orthopterans have recently become important subjects in evolutionary biological studies and are also increasingly used in the field of conservation as indicators of undisturbed habitat. The book comprises the following chapters: Introduction; Acoustic Methods; Sound Production and Reception of European Orthoptera; The Nature and Function of the Songs; The Value of the Songs in Taxonomy and Identification; Key to the singing Orthoptera of Western Europe, based primarily on their Songs; and other Animal Sounds that could be confused with Orthoptera Songs – illustrated with over 1600 oscillograms; three Appendixes (Check-list of the species included; Summary of Nomenclatural Changes; Data for the Song Recordings); Glossary; References; Index to Vernacular Names; and General Index.
This manual systematically describes basic management techniques needed to ensure best practices in raising crickets for food production. These techniques are based on 20 years of practical experience in cricket farming in Thailand, and previously unpublished data and knowledge collected by the author and support team. Robust research data related to cricket farming is still lacking, but will undoubtedly increase over time. However, in the interim, the growing cricket farming sector can be enhanced through the application of known best practices and related guidance.
