Proceedings of the Symposium on Management of Western Bark Beetles with Pheromones

Pages : 52
Book Description
Proceedings of the Symposium held in conjunction with the Annual Meeting of the Pacific Branch, Entomological Society of America. The objective of the meeting was to set in the record the status of research & development of semiochemicals for management of bark beetle-caused mortality in western North America. Despite the fact that some semiochemicals are being used in various bark beetle management scenarios in western North America there is need for additional research. Various semiochemical-based bark beetle management tactics such as spot baiting, trap-out, concentration & containment, anti-aggregation, & use of competing species are all under rigorous field testing.

A Catalog of Scolytidae and Platypodidae (Coleoptera).
Author: Donald E. Bright
Publisher: NRC Research Press
ISBN: 9780660167091
Category : Electronic books
Languages : en
Pages : 380
Book Description
This publication supplements Wood & Bright's 1992 catalogue of the world's Scolytidae and Platypodidae (bark beetles), updating the taxonomy of these two families to nearly the end of 1995 and including all known literature references to the end of 1994 (plus references to articles missed in the earlier bibliography). References which provide new information on taxonomy, host plants, or biology of a species are also included. The format of the supplement closely follows that of the 1992 catalogue. Each genus & species is listed with its page number from that catalogue; additional information on figures, distribution, hosts, and references to other subject areas are given. The publication also includes lists of host plants, arranged by scientific name, and the beetles attacking them.
