The first record of red scale in Kenya Colony in the file of the Entomological Laboratory is for 1914, on citrus. It is known that the scale has been brought into the country in at least one consignment of citrus, which, being accompanied by a certificate from the country of origin that the plants were free from insect pests, was allowed to enter the country under the Plant Import Regulations then in force, without being inspected. It seems, therefore, likely that red scale is not indigenous to the country, but an introduced pest.
