The date palm scale P. blanchardi is considered a serious pest in Algeria . The intense population of white scale not only hinders the normal development of the plant, but it also causes premature drying of djérids, and leads to the total loss of the palm.  In 2012 and 2013 a study on the bio-ecology of Parlatoria blanchardi is conducted in five  stations;  Chaâiba, Oumache,  Oasis of Biskra,  Outaya and Mzeraa. four generations per year are reported. The first generation occurs at the beginning of the summer in 2011 and 2012, the second in mid-July 2011  and 15 August 2012, the third at the end of September 2012 and 15 October 2013 and the fourth generation at the end of December 2011 and mid-January 2012.
