The problems that arise in developing a sampling design for the various life stages of the larch casebearer, Coleophora laricella (Hbn), are treated in relation to the changes in population density and distribution throughout the life cycle of the insect.
The basic principles of population sampling are followed in respect to stratification of the sampling universe into its logical components. Solo Survival: How to Survive Alone in the Wilderness for 1 week --Eastern Woodlands - Duration: Tom McElroy-Wild Survival Recommended for you.
