“…Actually, the lethal concentrations of the population from Ebro (Spain) was in the lower range of the values obtained, though Bt maize in this area represented Ϸ70% of the transgenic maize cultivated in Spain in 2004 Ð2005. This Þnding is consistent with the lack of resistant development to Cry1Ab in Spanish populations (Farinó s et al 2004(Farinó s et al , 2011. Moreover, binding site analysis performed with S. nonagrioides larvae revealed that Cry1F and Cry1Ab proteins have different high-afÞnity binding sites (González-Cabrera et al 2006), making the development of cross-resistance unlikely.…”

Maize hybrids expressing the Cry1F toxin provide efficient control of lepidopteran pests. The Mediterranean corn borer, Sesamia nonagrioides (Lefèvre), is one of the most damaging pests of maize in the Mediterranean basin. In this work we firstly determined the efficacy of maize hybrids expressing the Cry1F toxin (event TC1507) to control neonates of S. nonagrioides. Leaf tissue feeding bioassays revealed that TC1507 maize is highly effective against this pest, and the percentage mortality obtained was comparable to that obtained with a Cry1Ab-expressing maize hybrid (Compa CB, event 176), which is known to be highly efficacious against S. nonagrioides. Secondly, interpopulation variation in the susceptibility to the Cry1F insecticidal protein was established for nine field-collected populations of S. nonagrioides (three Spanish, two French, two Italian, one Greek, and one Turkish). Estimates of the susceptibility of larvae to the Cry1F toxin showed low variability in lethal concentrations and growth inhibition concentrations among field populations. Moreover, no significant differences were found when they were grouped by geographical areas [Western Mediterranean (Spain and France) versus Eastern Mediterranean (Italy, Greece and Turkey)] or by history of exposure to Bt plants (Spanish vs. other populations). Therefore, the minor differences found in field populations can be attributed to natural variation in sensitivity to Cry1F. The importance of establishing baselines of susceptibility for resistance detection is discussed. Future changes in susceptibility of S. nonagrioides populations to Cry1F could be documented based on this baseline data.

“…Instead of incorporating the Bt-protein uniformly in the diet, it is added to the surface of the diet (e.g., Marçon et al, 1999;Siegfried et al, 2000Siegfried et al, , 2005Farinós et al, 2004Farinós et al, , 2011Farinós et al, , 2012Blanco et al, 2008;Gaspers et al, 2011). Important advantages of the surface treatment are the lower amount of Bt-protein required for each test and the reduction in costs associated with Btprotein preparation (Blanco et al, 2008).…”

“…Baseline data should be established preferably before the first introductions of maize 59122, but at least during the initial years of its launch prior to high market penetration. Ideally, the same areas should be monitored over time to reduce the natural geographical variation in susceptibility (Farinós et al, 2004(Farinós et al, , 2011(Farinós et al, , 2012Saeglitz et al, 2006;Gaspers et al, 2011). Appropriately designed sampling strategies should account for the abundance, distribution and dispersal behaviour of WCR, and local variability in susceptibility levels.…”

This Scientific Opinion reports on a risk assessment on an application for placing on the market of genetically modified maize 59122 for import and processing for food and feed uses and cultivation. The EFSA GMO Panel considers that maize 59122 is unlikely to have any adverse effect on the environment, except for the possible evolution of resistance to the Cry34Ab1/Cry35Ab1 proteins in coleopteran target pests. The Panel recommends the implementation of appropriate and diversified insect resistance management strategies and case-specific monitoring to delay and monitor the possible evolution of resistance to Cry34Ab1/Cry35Ab1 in coleopteran target pests, respectively. In addition, the Panel recommends revision of the applicants' insect resistance management plan and the proposed post-market environmental monitoring plan. Although maize 59122 is tolerant to glufosinate-ammonium-based herbicides, the Panel did not assess the potential adverse effects associated with the use of such herbicides on maize 59122, as maize 59122 will not be marketed in the European Union as a herbicide-tolerant crop. This Scientific Opinion updates the previous Panel safety evaluation of the food and feed uses, and import and processing of maize 59122 and derived products. The Panel concludes that the information available for maize 59122 addresses the scientific comments raised by Member States and that maize 59122, as described in this application, is as safe as its conventional counterpart and commercial maize varieties with respect to potential adverse effects on human and animal health. If subjected to appropriate management measures, the cultivation of maize 59122 is unlikely to raise safety concerns for the environment.

Following a request from the European Commission, the European Food Safety Authority (EFSA) evaluated the documentation submitted by France under Article 34 of Regulation (EC) 1829/2003 in support of its request to prohibit the cultivation of genetically modified maize MON 810 in the EU. Neither the scientific publications cited in the documentation submitted by France with relevance to maize MON 810 nor the arguments put forward by France reveal any new information that would invalidate the previous risk assessment conclusions and risk management recommendations made by the EFSA GMO Panel. EFSA considers that the previous GMO Panel risk assessment conclusions and risk management recommendations on maize MON 810 remain valid and applicable. Therefore, EFSA concludes that, based on the documentation submitted by France, there is no specific scientific evidence, in terms of risk to human and animal health or the environment, that would support the adoption of an emergency measure on the cultivation of maize MON 810 under Article 34 of Regulation (EC) 1829/2003.
