JOURNAL OF APPLIED ENTOMOLOGY - FEV 2017 - Fitness costs associated with Cry1F resistance in the European corn borer. Introduction The European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae), has been an economically important pest of maize in North America since accidental introduction to the eastern Unites States nearly a century ago (Mason et al. 1996; Siegfried and Hellmich 2012).
Injury caused by O. nubilalis to whorl- and reproductive-stage maize can result in significant yield loss (Mason et al. 1996). In 1996 and 2001, respectively, maize producing insecticidal toxins Cry1Ab and Cry1F, derived from the bacterium Bacillus thuringiensis (Bt), was commercialized for the management of O. nubilalis (EPA 2010). By 2015, Bt hybrids accounted for 81% of the total area planted to maize (ERS 2015). The extensive use of Bt maize targeting this pest has resulted in areawide suppression of O. nubilalis populations in several Midwest states (Hutchison et al. 2010). The evolution of pest resistance to Bt crops is, arguably, the greatest threat to the success of this management tool. Methods. Int J Mol Sci. 2016 Oct; 17(10): 1561.

The model was also used to estimate the efficacy of certain mitigation measures.

CHECKBIOTECH 14/12/10 Auburn researchers evaluate Bt corn hybrids. Whenever you buy insurance, it’s helpful to weigh the cost versus the benefit.
In other words, does the inherent risk justify the premium being paid? The same should be true whenever a grower makes the decision of whether or not to plant a Bt corn hybrid. “Bt corn is really a form of crop insurance that comes in the seed bag. The presence of one or more Bt genes in a corn hybrid will not increase yield potential. Instead, the gene(s) prevent yield losses from certain insects,” according to a recent evaluation of Bt corn hybrids conducted by researchers at Auburn University, including Kathy Flanders, Extension entomologist; Brenda Ortiz, Extension agronomist; Austin Hagan, Extension plant pathologist; and other cooperators. The most important thing to remember, states the report, is that if the population of the target insect in your field or area is high enough, Bt corn will pay off.

A preliminary study was performed by Eduardo G.
Virla of PROIMI-Biotecnología in Argentina and colleagues to investigate the relationship of Bt corn with cry1F protein to control the fall armyworm (Spodoptera frugiperda) and the corn leafhopper (Dalbulus maidis), a non-target pest. They aimed to study the effect of the transgenic corn on the process of laying eggs and the egg hatching rate of leafhoppers. Male and female corn leafhoppers were released in cages that contained two potted plants - one Bt corn plant in vegetative stage, with two visible leaf collars and a non-Bt corn plant.
The number of eggs and hatched nymphs were recorded. More eggs and hatched nymphs were observed on the Bt plant. Agron. Sustain. Dev. Volume 30, Number 4, October-December 2010 Lower mycotoxin levels in Bt maize grain. Agron.
