  • Notes: [Special Issue: Proceedings of the ISSIS IX International Symposium on Scale Insect Studies held at The University of Padua, Italy, Sept. 2-8, 2001.] The soft scale P. tenuivalvata was discovered in Egypt in 1992 and, within a few years, has become the major pest of sugarcane, especially in upper Egypt. This paper describes the first instar nymph and second and third instar female nymphs of this species and provides a key for their separation.
