However, as the methodology for insect resistance monitoring remained unchanged compared to previous PMEM reports, the GMO Panel reiterates its previous recommendations for improvement of the insect resistance management plan. The GMO Panel considers that the farmer alert system to report complaints regarding product performance could complement the information obtained from the laboratory bioassays, but encourages the consent holder to provide more information in order to be in a position to appraise its usefulness. The data on general surveillance activities do not indicate any unanticipated adverse effects on human and animal health or the environment arising from the cultivation of maize MON 810 cultivation in 2014. The GMO Panel reiterates its previous recommendations to improve the methodology for the analysis of farmer questionnaires and conduct of the literature review in future annual PMEM reports on maize MON 810. The GMO Panel urges the consent holder to consider how to make best use of the information recorded in national registers to optimise sampling for farmer questionnaires, and requests to continue reviewing and discussing relevant scientific publications on possible adverse effects of maize MON 810 on rove beetles. Also, the GMO Panel encourages relevant parties to continue developing a methodological framework to use existing networks in the broader context of environmental monitoring.

The 2014 case-specific monitoring (CSM) dataset on maize MON 810 consists of a survey on compliance with non-Bacillus thuringiensis (non-Bt) refugia in Spain and Portugal, and dose-response and diagnostic dose bioassays to monitor for changes in susceptibility to Cry1Ab in target pests (European and Mediterranean corn borer) collected from Iberian populations. The 2014 PMEM report shows partial non-compliance with the implementation of non-Bt refugia in Spain as observed in previous years. Therefore, the GMO Panel recommends that the consent holder consolidates its efforts to increase the level of compliance, especially in regions of high maize MON 810 uptake, where such compliance is crucial to ensure the effectiveness of the ...
