In general, genetically engineered plants actually have less innate pest resistance, which farmers then compensate for by spraying pesticides onto them, because it allows them to trade off that natural pesticide production for faster growth.
ChristianKl may be thinking of Bt corn (maize) and, for instance, the Starlink corn recall. Bt corn certainly does express a pesticide, namely Bacillus thuringiensis toxin.
