Notes: Title in English: [Life cycle, dynamics and natural enemies of Saissetia oleae Olivier (Homoptera: Coccidae) in olive orchards in Alto Palancia (Castellón-Spain).] Two olive orchards located in Alto Palancia (East Spain) were monitored for incidence of S. oleae between April and November 2002. As in other olive-growing areas in the Mediterranean Basin, S. oleae presented one generation, with crawlers peaking during the summer. At that time crawlers represented more than 99% of all living stages. Although both orchards received chemical treatments during the study period, four different microhymenopterans were recovered from S. oleae-infested shoots (Coccophagus lycimnia, Scutellista caerulea, Metaphycus flavus and M. lounsburyi). These could play an important role on regulating S. oleae populations in spring. It would be interesting to repeat this study on non-treated orchards to check if natural mortality factors could keep S. oleae numbers below its economic threshold.
