Abstract

In Cyprus,Aphytis chrysomphali (Mercet) andAphytis melinus DeBach are the only significant parasites of the California red scale,Aonidiella aurantii (Maskell).A. chrysomphali, presumably native, has been virtually displaced byA. melinus from the interior dry areas of the island after the importation of the latter in 1961. Presently the former parasite dominates only in some of the coastal areas with a mild and rather humid climate.Aphytis ? coheni DeBach that initially displacedA. chrysomphali in the release areas, was replaced by the latter parasite and was occasionally found in small numbers only in one location. Traces ofAphytis ?lingnanensis Compere were also found in some locations. Two otherAphytis spp., imported from California, were released and recovered but it is too early to determine their permanent establishment and significance.

Résumé

A Chypre,Aphytis chrysomphali (Mercet) etAphytis melinus DeBach sont les seuls parasites significatifs du pou de Californie,Aonidiella aurantii (Maskell).A. chrysomphali, probablement indigène, a été virtuellement déplacé parA. melinus des régions intérieures sèches de l'île après l'importation de celui-ci en 1961. A présent,A. chrysomphali domine seulement dans les régions côtières qui ont un climat doux et plutôt humide.Aphytis ?coheni DeBach, qui initialement avait déplacéA. chrysomphali dans les régions de libération, a été remplacé par ce parasite et est parfois trouvé en petits nombres seulement dans une région. Des traces deA. ?lingnanensis Compère furent également trouvées dans certaines régions. Deux autresAphytis spp., importés de Californie, furent libérés et repris mais il est trop tôt pour pouvoir déterminer leur installation permanente ainsi que leur signification.
