I have aproblem with the leaves of the raspberries being eaten until they resemlbe lace I have found green hard backed beetles on the plants

A photograph of both leaf and Beetle would have been useful...The Beetle may not be the culprit, it could be feeding on the culprit. See if you can find it here
