INTEGRATED PEST MANAGEMENT OF MEDITERRANEAN BLACK SCALE INS CT, SAISSETIA OLEAE (HOMOPTERA : COCCIDAE) ON OLIVE TREES ,

Abstract

The Mediterranean black scale, Saissetia oleae (Oliver) (Homoptera: Coccidae) is a serious pest of olive in Egypt. The present work is an attempt to use different pest management techniques for controlling this species. It includes the population dynamics of S. oleae and its natural enemies as well as the efficacy of spraying of some natural compounds and IGR (Bupofezin) on them. The results indicated that S. oleae had two generations per year on olive trees in April and August during both studied years (' 1998-1999 and 1999- 2000). This work indicated that Metaphycus bartletti Annecke & Mynhardt and Chyrsoperal carneae (Stephens) were the effective natural enemies of S. oleae on olive trees. Buprofezin was the most effective compound on the stages of S. olecte and ga\ie toxic effect against its natural enemies. M. pede, Jojoba, Neemazal and Biofly gave a moderate toxic effect against the natural enemies ofthis species.
