Liphschitz, N., & Mendel, Z. 1987 Histological studies of Pinus halepensis stem xylem affected by Matsucoccus josephi (Homoptera: Margarodidae).. IAWA Bulletin 9(4): 369-376.

Notes: The injury caused by Matsucoccus josephi to naturally artifically infested Pinus halepensis was studied with special emphasis on the reaction of the cambium to the insect attack and the subsequent changes in the xylem. Scars from stem injury were easily detected macroscopically due to discoloration on the stem cross section and involve narrowing of annual rings at the injury site for several years.
