Increased long-flight activity triggered in beet armyworm by larval feeding on diet containing Cry1Ac protoxin. [PDF]
PLoS ONE, 2013 Evaluating ecological safety and conducting pest risk analysis for transgenic crops are vitally important before their commercial planting. The beet armyworm, Spodoptera exigua, a long-distance migratory insect pest, is not a direct target of transgenic ...

Editing the kinesin-12 gene affects responses to Bt toxin Cry1Ac in Helicoverpa zea [PDF]
Scientific ReportsCrops genetically engineered to produce insecticidal proteins from Bacillus thuringiensis (Bt) are used globally to manage key insect pests. However, the evolution of resistance to Bt proteins in at least 11 pest species has reduced the effectiveness of ...

Low temperature exposure influences nitrogen metabolism resulting in decreased Cry1Ac insecticidal endotoxin content in cotton seeds [PDF]
BMC Plant BiologyBackground Sudden temperature drops, resulting from extreme weather events, often occur during the boll-setting period of cotton in Xinjiang, China, causing decreased expression of Bacillus thuringiensis (Bt) insecticidal proteins in cotton bolls.

Large-scale assessment of lepidopteran soybean pests and efficacy of Cry1Ac soybean in Brazil
Scientific Reports, 2021 The soybean technology MON 87701 × MON 89788, expressing Cry1Ac and conferring tolerance to glyphosate, has been widely adopted in Brazil since 2013. However, pest shifts or resistance evolution could reduce the benefits of this technology.
