Black scale, Saissetia oleae (Oliver), has, until recently, been a minor pest of olive in California, and the specific chemical controls established for black scale have seldom been used. Chemical control of another scale, Parlatoria, a more serious pest of olive, resulted in some inadvertent control of black scale.
