Download or read book Use of the Multi-Pher Trap to Monitor Spruce Budworm Populations written by Luc Joseph Jobin and published by Sainte-Foy, Québec : Forestry Canada, Quebec Region. This book was released on 1993 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Multi-Pher insect trap was first manufactured and marketed in 1984. In 1985, it was used in the development of a detection and monitoring system for the spruce budworm over a major part of the distribution area of the species in North America. From 1984- 89, 12 experiments to assess and optimize trap effectiveness were conducted in balsam fir stands infested by spruce budworm in the Gaspe Peninsula. Three models of the trap were compared and the number of males captured was considered an adequate measure of trap effectiveness. Testing compared lure brand and holder, insecticide, funnel, baffle, colour and trap placement, cleanliness, and holder.

Book Synopsis Guidelines for Using Sex Pheromone Traps to Monitor Eastern Spruce Budworm Population Densities by : M. D. Tenhagen
Download or read book Guidelines for Using Sex Pheromone Traps to Monitor Eastern Spruce Budworm Population Densities written by M. D. Tenhagen and published by . This book was released on 1996 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex pheromone traps are ideal for monitoring larval populations of spruce budworm during periods between outbreaks when larval densities are at extremely low levels. This note provides guidelines on the use of such traps to monitor budworm populations. It describes trap components and materials, assembly and handling of traps, selection of trapping sites and trap deployment, timing of trap-setting, collection of traps, and interpretation of catches.

Book Synopsis Computer Simulation for Integrated Pest Management of Spruce Budworms by : Carroll B. Williams
Download or read book Computer Simulation for Integrated Pest Management of Spruce Budworms written by Carroll B. Williams and published by . This book was released on 1982 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some field studies of the effects of various insecticides on the spruce budworm (Choristoneura sp.) and their parasites have shown severe suppression of host (budworm) populations and increased parasitism after treatment. Computer simulation using hypothetical models of spruce budworm-parasite systems based on these field data revealed that (1) effective parasites produce greater stability in budworm populations than ineffective ones and are more resistant to changes induced by insecticides; and (2) the level of budworm population suppression in most budworm·parasite systems is not proportional to the amount of insecticide applied. Only high insecticide dosages produce any effect on the budworm population. Cost-benefit analyses showed that very high investments are worthwhile, but moderate investments produce little effect. The study demonstrated that the computer simulation pmcess helps to define kinds of information needed for understanding the budworm-parasite system, and can predict system behavior under varying conditions.
