“…Bt-maize that is not truly high dose could thus yield susceptible adults that are available to mate with any WCR potentially carrying resistance alleles, and hence contribute to slow the onset of resistance evolution (Crowder and Onstad, 2005). Moreover, evidence has shown that several grass species can support the growth of WCR larvae (Clark and Hibbard, 2004;Oyediran et al, 2004;Wilson and Hibbard, 2004;Breintenbach et al, 2005) and may therefore serve as an additional (unstructured) refuge in which such host plants are abundant and appropriately distributed (Chege et al, 2005(Chege et al, , 2009Oyediran et al, 2005).…”

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.

“…The larvae, which emerge during the spring, can survive only on the roots of corn and on a limited number of grass species (Levine and Oloumi-Sadeghi 1991, Oyediran et al 2004. For many years, corn producers throughout the north central United States have managed this pest by practicing crop rotation, planting corn and a nonhost crop [such as soybean, Glycine max (L.)] in alternate years.…”

Analysis of the Dynamics of Adaptation to Transgenic Corn and Crop Rotation by Western Corn Rootworm (Coleoptera: Chrysomelidae) Using a Daily Time-Step Model

Western corn rootworm, Diabrotica virgifera virgifera LeConte, has overcome crop rotation in several areas of the north central United States. The effectiveness of crop rotation for management of corn rootworm has begun to fail in many areas of the midwestern United States, thus new management strategies need to be developed to control rotation-resistant populations. Transgenic corn, Zea mays L., effective against western corn rootworm, may be the most effective new technology for control of this pest in areas with or without populations adapted to crop rotation. We expanded a simulation model of the population dynamics and genetics of the western corn rootworm for a landscape of corn; soybean, Glycine max (L.); and other crops to study the simultaneous development of resistance to both crop rotation and transgenic corn. Results indicate that planting transgenic corn to first-year cornfields is a robust strategy to prevent resistance to both crop rotation and transgenic corn in areas where rotation-resistant populations are currently a problem or may be a problem in the future. In these areas, planting transgenic corn only in continuous cornfields is not an effective strategy to prevent resistance to either trait. In areas without rotation-resistant populations, gene expression of the allele for resistance to transgenic corn, R, is the most important factor affecting the evolution of resistance. If R is recessive, resistance can be delayed longer than 15 yr. If R is dominant, resistance may be difficult to prevent. In a sensitivity analysis, results indicate that density dependence, rotational level in the landscape, and initial allele frequency are the three most important factors affecting the results.

Teelt van sorghum als voedergewas lijkt perspectiefvol in Nederland

Rapport 1064Kasper, G.J., Teelt van sorghum als voedergewas lijkt perspectiefvol in Nederland.Wageningen Livestock Research, Rapport 1064.Samenvatting NL Sorghum kan in korte tijd veel voedingsstoffen opnemen, ook op armere en droge gronden, en gaat efficiënt om met voedingsstoffen, vooral stikstof en water. Het gewas groeit goed op gronden waar ook snijmaïs het goed doet. Recente proefveldonderzoeken in Nederland tonen ten opzichte van maïs gelijke tot 25% hogere opbrengsten (ds/ha/jaar), hogere gehalten aan ruw-eiwit (tot 69%) en zetmeel (-10 tot +24%). Kennishiaten zijn: 1) kennis over de voederwaarde, 2) gebrek aan praktische kengetallen over teelt, fermentatie en dierprestaties, 3) combiteelt winterrogge-sorghum in het groeiseizoen en 4) tussenteelt van sorghum bij continuteelt van snijmaïs. Summary UKSorghum absorbs a lot of nutrients in a short period of time, even on rather poor and dry soils. The crop has a favourable nitrogen and water use efficiency. The crop grows well on soils where maize grows well too. Recent field trial studies in the Netherlands show equal or higher than 25% yields (dry matter/ha/year), higher levels of crude protein (up to 69%) and starch (-10% to +24%) than maize.Knowledge gaps are: 1) feed evaluation characteristics, 2) practical data on cultivation, fermentation and animal performance, 3) combi-cultivation winter rye and sorghum per growing season, and 4) intercropping of sorghum in continuous maize cropping. De belangrijkste kennishiaten voor onderzoek van sorghum in Nederland zijn:• voederwaardering sorghum: het ontbreekt voornamelijk aan gegevens over de (darm)verteerbaarheid en de afbreekbaarheid in de pens.• melkveehouders vragen concrete cijfers van praktijkpercelen (o.a. drogestofopbrengsten), maar ook voederwaardering, voeropname, mycotoxinendruk en dierprestaties van ingekuilde sorghum.• het bepalen van broeikasgasemissies inclusief C-vastlegging in, en erosie van de bodem.• America. In Europe, most research data on the use of sorghum as dairy cattle feed originate fromFrance and Italy, where the crop has been evaluated for yield, feeding value including animal performance. In Italy, the effects of sorghum on greenhouse gas emissions and milk composition also have been studied.The purpose of this research is to explore the potential of sorghum as a fodder crop in North WestEurope with emphasis on the Netherlands, including feed and animal performance, compared to those of maize.Sorghum as a fodder crop can be distinguished in two types: a type that resembles grass (Sorghum Sudan) and a type that contains both green leaf and grain (Sorghum bicolor). Sorghum can grow on all soils where maize also grows well, preferably with a pH of 6.5 to 8. The crop can quickly absorb a lot of nutrients, even on rather poor and dry soils. This means that sorghum is efficiently dealing with nutrients, especially nitrogen and water. In the temperate climate of North West Europe, especial attention must be taken to the seeding period (germination, young plant and period from bloom), th...
