TY - JOUR T1 - An attempt to compare two methods to determine population size of pine foliophages wintering in forest litter A1 - Ignacy KorczyƄski A1 - Kamil Remenda JO - Acta Sci.Pol.

It was found that the method consisting in the measurement of the number of insects in the stand in 10 small plots was not markedly better than the method consisting in the measurement of the population size under the crown of one tree.
