The area of my my scientific activity is generally known as biochemical ecology, which is a branch of ecology that describes the biochemical aspects of interactions among organisms and between organisms and the environment. In particular, my research is focused on the behavioral responses of aphids to the activity of plant allelochemicals. The aim of this research is learning the feeding mechanism of aphids depending on their systematic affiliation and the host plant range, which contributes to enriching the knowledge about the coevolution of plants and insects with piercing-sucking mouthparts. In addition to the cognitive values inherent in basic research, these studies also have application value. The understanding of the mechanisms underlying the selection and acceptance of host plants by aphids opens the way to developing environmentally friendly methods of reducing the number of these insects in agricultural crops. Research on the influence of natural and structurally modified allelochemicals on the behavior of aphids enables the detection of potential food deterrents with high specificity of activity. I am a full professor at the Institute of Biological Sciences, University of Zielona Góra, Poland.
