It has been demonstrated that pheromonal traps applied to different
agricultural crops can monitor the development of populations of fleas Mamestra
brassicae, Heliothis armigera, Agrothis segetum, and inform about the population
density, the number of generations and the peaks of activity in each generation. It was
appreciated that the species with the most plastic biological potential to adapt to the
changing environmental conditions is Heliothis armigera, which surpasses the Agrotis
segetum species by about 10% after the competition activity in the case when both
species live on one and the same agricultural lot.
