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 Monitoring Larval Populations of the Douglas-fir Tussock Moth and the Western Spruce Budworm on Permanent Plots by : Robert R. Mason
Download or read book Monitoring Larval Populations of the Douglas-fir Tussock Moth and the Western Spruce Budworm on Permanent Plots written by Robert R. Mason and published by . This book was released on 1994 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Procedures for monitoring larval populations of the Douglas-fir tussock moth and the western spruce budworm are recommended based on many years experience in sampling these species in eastern Oregon and Washington. It is shown that statistically reliable estimates of larval density can be made for a population by sampling host trees in a series of permanent plots in a geographical monitoring unit. The most practical method is to estimate simultaneously densities on a plot of both insect species by the nondestructive sampling of foliage on lower crown branches of host trees. This can be done either by counting all larvae on sample branches or by estimating the frequency of occurrence of a selected threshold number of larvae in samples. Statistics are given on the expected within- and between-plot variances and the number of sample plots needed in different sized monitoring units. In large monitoring units, plot densities of tussock moth and budworm larvae usually are not normally distributed, but they can be normalized by logarithmic transformation to predict the probability of subpopulations of any given density occurring somewhere in the unit. It is urged that sampling methods be consistent and that monitoring be done annually to accumulate continuous databases that reflect the behavior of defoliator populations over a long period.
