Abstract

Since Maconellicoccus hirsutus (Green), a pest of many plants including Hibiscus, was introduced into Egypt in 1908, probably from the Oriental Region, it has spread to much of tropical Africa. There is little information available on its control, but the encyrtid Anagyrus kamali Moursi is known to give good control in Egypt. The ladybird Cryptolaemus montrouzieri Mulsant is a voracious feeder on M. hirsutus in Egypt, but it does not survive the Egyptian winter, although it may be useful in the tropical areas. M. perforatus (De Lotto) is synonymized with M. hirsutus, and the distribution and host-plants of this species in Africa are discussed. A lectotype is designated for M. ugandae (Laing), a species now known to occur throughout tropical Africa, especially on coffee and cocoa. It is illustrated and redescribed and compared with M. hirsutus. M. bardus De Lotto, known from South Africa only, is excluded from the study because it probably belongs to the genus Chorizococcus.
