Influence of temperature and flowers on longevity of adult Platygaster demades

Researches the failure by Platygaster demades to provide effective biological control of apple leaf curling midge (ALCM). Postulates that it may be because the second, spring generation of the parasitoid is asynchronous with that of its host. Puts forward the suggestion for using buckwheat in apple orchards to prolong the first generation of P. demades sufficiently to synchronise with the second generation population of ALCM.
