oa Journal of the Entomological Society of Southern Africa - Insects associated with Pseudococcus spp. (Homoptera) in Palestine, with notes on their biology and economic status
During 1937 and 1938, citrus groves in the neighbourhood of Petah Tikvah, Mikveh Israel and Rishon-le-Zion were infested with mealy bugs showing distinct differences from the common citrus mealy bug, Pseudococcus citri Risso. and which were, until then, not known to occur in Palestine. Material was sent for examination to the British Museum and to authorities in the United States and elsewhere. Laing, of the British Museum, first reported that it was Ps. comstocki (Kuwana). Upon examination of further material, Laing realized that at least three species were included.
