Abstract

A new scale insect, Stictococcus vayssierei, has been found attacking all the underground parts of cassava. From surveys in all the cassava-growing areas of Cameroon, the insect seems to be limited to the southern part of the country, where it is a major pest of cassava. This is the semi-humid zone with a bimodal rainfall pattern. Field populations of the pest vary within fields and regions. More than 200 insects were observed on a single plant in many fields. Seasons seem to influence field populations.
