Several methods are used for monitoring #resistance to Bt crops. Such as #F2 screen, F1 screen, sentinel plots, DNA marker method, discriminating dose assay, dose-response assay etc., Among these most widely used method is F2 screen due to its high accuracy in detecting rare and any trivial form of resistance. F2 screen is so sensitive that it can detect resistance even when other methods fail to detect resistance. Several reports have been published that detected rare resistance using F2 screen in #Fall armyworm (for more information refer to this article https://doi.org/10.1016/j.cropro.2014.06.019)

Endotoxins from Bacillus thuringiensis are effective against FAW. Especially, Cry1Ac and Cry1F toxin. GMO such as Bt-Maize expressing Cry1F and Cry1Ac expressing Cotton are efficacious against FAW. However, FAW is evolving resistance to Cry toxins (you can see many reports from Brazil). Alternatively, bacteria associated with EPN's might be the next best source for Insect control.
