Nieuwsbericht | 12-09-2019 | 12:00 Article by British agricultural economist assesses the economic and environmental impacts that have arisen from the adoption and use of genetically modified (GM) insect resistant (IR) maize in Spain and Portugal in the 21 years since first planted in Spain in 1998.

AGROBERICHTENBUITENLAND_NL 12/09/19 Bt maize leads to an additional maize production of 1.89 M tons in Spain and Portugal

GM crop technology has been widely used in maize in many parts of the world over the last 21 years. In the EU, the only GM maize trait authorized for planting has been IR maize (resistant to corn borer), which was first authorized in 1998. The original IR maize trait approved for planting in the EU was Bt 176. Since 1998, the cultivation of Bt maize has allowed Spanish and Portuguese farmers to obtain an additional production of 1.89 million tons, using fewer resources and helping to reduce pressure on some scarce ones such as water.

Between 1998 and 2018, the total area under Bt maize in the two countries was 1.65 million hectares.

BMC 12/12/16 Baseline susceptibility of different European lepidopteran and coleopteran pests to Bt proteins expressed in Bt maize: a systematic review

Therefore, we collected data on the baseline susceptibility of different lepidopteran/coleopteran maize pests. Besides the use of Bt proteins in Bt maize insecticidal Bt proteins are used also in sprays like Dipel®. These are applied against different insect pests worldwide [14] in both organic and conventional agriculture [15]. Considering our inclusion criteria, we searched for studies of the Bt proteins that are expressed in commercial Bt maize varieties and that are toxic to European target organisms. Therefore, we excluded studies that used Bt formulations or the untruncated version of the Bt proteins for testing (23% of the studies).

PLOS 03/07/18 Effects of field history on resistance to Bt maize by western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) Abstract Western corn rootworm, Diabrotica virgifera virgifera LeConte, has evolved resistance to transgenic maize, Zea maize L., that produces the insecticidal protein Cry3Bb1, which is derived from the bacterium Bacillus thuringiensis.

PLOS 03/07/18 Effects of field history on resistance to Bt maize by western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae)

We hypothesized that the level of Cry3Bb1 resistance in populations of western corn rootworm could be influenced by farming practices. To test this hypothesis, we evaluated the effect of field history on resistance to Cry3Bb1 maize by western corn rootworm. In 2013 and 2014, rootworm adults were collected from the four types of maize fields: 1) current problem fields, 2) past problem fields, 3) rotated maize fields, and 4) continuous maize fields. Those field populations along with seven Bt-susceptible control populations were tested for Cry3Bb1 resistance with both plant-based and diet-based bioassays. Editor: Dean E. Ciênc. agrotec. vol.41 no.2 Lavras Mar./Apr. 2017 Efficacy of transgenic mayze insecticide treatment to control fall armyworm in late-season maize in São Paulo state, Brazil. Late-season maize in Brazil is characterized by rainfed cultivation, and is sown between January and April, after the summer crop, usually after early soybean.

Ciênc. agrotec. vol.41 no.2 Lavras Mar./Apr. 2017 Efficacy of transgenic mayze insecticide treatment to control fall armyworm in late-season maize in São Paulo state, Brazil

In the 2015 growing season, the acreage of late-season maize in the state of São Paulo was 370,100 hectares and the mean yield 4494 kg ha-1 (Conab, 2015). One of the main factors compromising the yield of late-season maize is the incidence of insect pests, whose populations have increased every year, reducing crop yields and thus causing losses to farmers (Fernandes; Carneiro, 2006).
