I feel that I must start off by explaining that the title of this address is something of a misnomer. I started off with the intention of telling you about as many of our insect pests of grassland as I could, but once I started on the grass grub it was clear I could not do this, as my time was being completely taken up with this one pest and I decided to ,devote the whole paper to give you an appreciation of the control position concerning grass grub today and to describe some of our plans for the future.
