Logistic regression approach to the prediction of tree defoliation caused by sawflies (Hymenoptera: Symphyta)
Journal of Forest Science 50 (6), 284-291
Abstract: A relationship between the abundance of phytophagous insects assessed from soil samples (in the case of Cephalcia lariciphila) or yellow sticky boards (in the case of T. nigritus) and percentage of defoliated trees was characterised by logistic regression.
