The larch casebearer is a permanent and constant pest of larch stands (Schwenke, ).The moth is found in nearly all larch stands within and without the natural occurrence of larch (Schwenke,Schwerdtfeger, ).Tree death caused by the casebearer is a rare event, but infested larch stands suffer significant growth reductions Cited by: 5.

Crookston Acephate Reduces Populations of Needlemining Larch Casebearer in Laboratory: The nonperiodic population wave: a case study of the larch casebearer Protocryptis sibiricella (Lepidoptera, Coleophoridae) Article (PDF Available) in Entomological Review 94(8) 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. The population dynamics of the larch casebearer (Coleophora laricella Hbn.) in the field and the physiology of larch needles serving as their feeding basis.

IPM is a pest population management system that utilizes all suitable techniques (biorational, chemical, cultural, fertiliza- tion, irrigation, monitoring with sex pheromone traps, resistant plant varieties, etc.) and information to reduce or manipulate pest populations that are maintained at tolerable levels (i.e., a few pests will still be.
