Abstract:
The efficacy of Bt maize MON 810-YieldGard® and of Trichogramma wasp against European corn borer (ECB) (Ostrinia nubilalis Hübner) was evaluated in the period of 2002-2008 in field trials on three localities in the Czech Republic. The efficacy of Bt maize on the reduction of the number of tunnels caused by ECB per 100 maize plants before harvest was always 100% and that in Trichogramma treatment was on average 50%. The mean increase of the yield of 15% and 10% was obtained in Bt maize and Trichogramma treatments, respectively in comparison with the untreated control. The damage curve and economic injury level by ECB on maize was developed for the evaluation of the yield losses and management of the pest control. The higher economic efficacy of growing Bt maize as compared to other control measures is documented.
