Abstract
Up to 1978 a programme for biological control of Quadraspidiotus perniciosus with mass reared Prospaltella perniciosi was carried out.
In the present situation all investigated Qu. perniciosus populations showed acceptable parasitation rates (from 11% up to 63%, mean 30%). On many sites the endemic endoparasitic wasp Aphytis sp. has a higher importance than Prospaltella.
