. Insect and disease conditions in the United States, 1979-83 : what else is growing in our forests?. Forest insects United States; Trees Diseases and pests United States; Plants Disease and pest resistance. Without Loran-C Decision Key, developed by the USDA Forest Service (Anderson and others 1983), considers variables, such as environment, economics, geographic location, and pest interaction, and then for- mulates management options for various scenarios. One advantage of this system is the ease with which it can be expanded or modified to include new technology—a more cost-effective approach than the publication of research results. Outlook The widely dispersed outbreak areas of 1983 were typical of an incipient outbreak, and most entomologists feel that beetle losses will increase throughout the Western Gulf States. Actual losses, however, will depend on winter temperatures and rainfall amounts. Resource managers are now better prepared than ever to deal with the southern pine beetle: detection, evaluation, and control techniques are all improving. Managers no longer think of the southern pine beetle as "just an insect ; Over the long run, losses can be reduced only through improved forest manage- ment. Such practices include. reducing the length of the rota- tion, thereby eliminating older, more susceptible timber, and planting trees suitable to the site. Managers will have to practice integrated pest management— management that is effective yet environmentally and economically responsible—if they hope to reduce southern pine beetle- caused losses. i.
