oa Journal of the Entomological Society of Southern Africa - Population dynamics of the Mediterranean black scale, Saissetia oleae (Oliv.), on citrus in Israel. 3. Occurrence of a yellow form



The presence of a yellow variety in the populations of the Mediterranean black scale, Saissetia oleae (Olivier) Homoptera: Coccidae), in Israel is reported. The phenology of this variety on citrus resembled that of the common type, but it was probably subject to differential mortality during the early adult stage. Females of this variety produced only yellow-form progeny.
