Biosafety research into Diabrotica resistant Bt-maize: indicator organisms and monitoring methods
… cultivation of the Bt-maize variety MON88017 on non-target arthropods in the maize herb-layer was assessed. The non-deregulated MON88017, its near-isogenic line DKC5143 and the two conventional hybrids DK315 and Benicia were cultivated on a field-release site. Sweep netting, sticky traps, cob and …
