Update of environmental risk assessment conclusions and risk management recommendations of EFSA (2016) on EU teosinte

EFSA Journal, Volume 20, Issue 4, April 2022., 2022
Abstract Teosinte, wild maize relatives originating from Mexico and Central America, emerged as a noxious agricultural weed in France and Spain. In 2016, the European Food Safety Authority (EFSA) issued a technical report that assessed the available scientific information on teosinte for its relevance for the environmental risk assessment (ERA) and ...

Asian corn borer damage is affected by rind penetration strength of corn stalks in a spatiotemporally dependent manner

Plant Direct, Volume 6, Issue 2, February 2022., 2022
Abstract Asian corn borer, Ostrinia furnacalis (Guenée), is an important insect pest of maize throughout most of Asia. The rind of a maize stalk is a key barrier against corn borer larvae boring into the plant. There is a need to better understand the relationship between stalk strength and O.

Insect pest management in the age of synthetic biology

Plant Biotechnology Journal, Volume 20, Issue 1, Page 25-36, January 2022., 2022
Summary Arthropod crop pests are responsible for 20% of global annual crop losses, a figure predicted to increase in a changing climate where the ranges of numerous species are projected to expand. At the same time, many insect species are beneficial, acting as pollinators and predators of pest species.

Unoccupied aerial systems discovered overlooked loci capturing the variation of entire growing period in maize

The Plant Genome, Volume 14, Issue 2, July 2021., 2021
Abstract Traditional phenotyping methods, coupled with genetic mapping in segregating populations, have identified loci governing complex traits in many crops. Unoccupied aerial systems (UAS)‐based phenotyping has helped to reveal a more novel and dynamic relationship between time‐specific associated loci with complex traits previously unable to be ...

Assessment of the 2019 post‐market environmental monitoring report on the cultivation of genetically modified maize MON 810 in the EU

EFSA Journal, Volume 19, Issue 7, July 2021., 2021
Abstract Following a request from the European Commission, the EFSA assessed the 2019 post‐market environmental monitoring (PMEM) report on the cultivation of Cry1Ab‐expressing maize event MON 810. Like previous years, there was full compliance with refuge requirement in Portugal and partial compliance with refuge requirements by Spanish farmers ...

Global warming and increasing maize cultivation demand comprehensive efforts in disease and insect resistance breeding in north‐western Europe

Plant Pathology, Volume 70, Issue 5, Page 1032-1046, June 2021., 2021
Climate change will shift maize cultivation northward, requiring continuous multi‐resistance breeding approaches against existing and invasive pathogens and insects. Abstract Maize productivity is threatened by global climate change. Climate change scenarios suggest that north‐western (NW) Europe will get warmer and drier during the main crop‐growing ...

QTL Mapping of Traits Associated with Dual Resistance to the African Stem Borer (Busseola fusca) and Spotted Stem Borer (Chilo partellus) in Sorghum (Sorghum bicolor)

International Journal of Genomics, Volume 2021, Issue 1, 2021., 2021
Sorghum (Sorghum bicolor (L.) Moench) is an important food crop in semi‐arid tropics. The crop grain yield ranges from 0.5 t/ha to 0.8 t/ha compared to potential yields of 10 t/ha. The African stem borer Busseola fusca Fuller (Noctuidae) and the spotted stem borer Chilo partellus Swinhoe (Crambidae), are among the most economically important insect ...

Sixteen Years of Bt Maize in the EU Hotspot: Why Has Resistance Not Evolved? [PDF]

PLoS ONE, 2016
The majority of Bt maize production in the European Union (EU) is concentrated in northeast Spain, which is Europe's only hotspot where resistance might evolve, and the main target pest, Sesamia nonagrioides, has been exposed to Cry1Ab maize continuously

Maize Resistance to Stem Borers Can Be Modulated by Systemic Maize Responses to Long-Term Stem Tunneling

Frontiers in Plant Science, 2021
Limited attention has been paid to maize (Zea mays L.) resistance induced by corn borer damage, although evidence shows that induced defenses have lower resource allocation costs than constitutive defenses. Maize responses to short- and long-term feeding
