Continuing the biological fight against a hardy foe – the maize-devastating western corn rootworm

CABI is continuing the fight against the maize-devastating western corn rootworm (Diabrotica virgifera virgifera) by collecting more than 22,000 live specimens of this chrysomelid beetle for further research into its biological control. Dr Stefan Toepfer has been busy in the maize fields of southern Hungary gathering the insects, which, of Mexican origin, have invaded many maize…
