    Description

    Numerous investigations have shown that forest insect outbreaks usually occur in specific habitats. Frequently these outbreaks do not generally extend to other territories occupied by these same host trees. Moreover, in every stand subjected to an outbreak, both slightly undamaged plots and heavily damaged plots are found. Perhaps some plots are initially more resistant to insect attack, and insect distribution within forest ecosystems may have a mosaic pattern. Therefore investigation of the relation between dendrophagous insect distributions and initial heterogeneity of ecosystems may help us to understand the nature of forest stand resistance. This question lends interest to the peculiarities of dendrophagous insect distribution in relation to forest borders because borders and different glades are important factors in forest ecosystem heterogeneity.
