oa Journal of the Entomological Society of Southern Africa - An attempt to control the Seychelles scale, Icerya seychellarum (Westw.) (Homoptera: Coccidae), in South Africa by introducing Cryptochaetum monophlebi Skuse (Diptera: Cryptochaetidae)
The author visited Pietermaritzburg in January, 1959, in order to investigate the heavy infestation of the Seychelles scale, Icerya seychellarum (Westw.), on the Australian chestnut tree, Castanospermum australe Cunn. (Leguminosae), in the centre of the city. Dead and dying trees were found but this was not necessarily due to the scale infestation. Many other trees although heavily infested were perfectly healthy. The Parks Department in Pietermaritzburg was very concerned about the infestation and contemplated spraying the trees, but biological control of the pest was considered to be desirable.
