SAMPLING LOW DENSITY SPRUCE BUDWORM POPULATIONS FOR ISOZYME ANALYSIS
Published online by Cambridge University Press: 31 May 2012
Extract
A convenient and efficient method of determining if qualitative changes are associated with changes in density of insect populations is to search for changes in isozyme frequencies (Stock and Guenther 1979). However, obtaining sufficient material for analysis of low density populations presents a problem. We have found that the use of sticky traps baited with synthetic pheromone is an efficient and practical method of surmounting this problem.
