Hi everyone,

        To throw in my two cents on the following.

        There are photos in the biology department here from the pest
management program of a wasp 'parastizing' an aphid. I don't like to use
the word parasitized with the wasp, because it's not the adult that's the
parasite, instead it lays it's eggs inside the aphid and then the larvae
eats its way out (nobody said the insect world was nice!).

        As Susan pointed out, there are several parasitic species which
are being used for biological control. Out here, a lot of research is
being dedicated to biological eradication of forest pest species.

        As I said, my two cents :)!

Kind regards,
