I am interested in understanding chemically mediated interactions in the larval stages mainly host plant preferences and molecular basis to larval olfaction (odorant receptors) compared to adults.
Using Egyptian cotton leafworm Spodoptera littoralis as a model species, I have been studying behavioral modulation in larva in response to sensory qualities from their host plants.
Current status: Extending the knowledge of larval modulation and host choice behaviors in adults from cotton leafworm to silver Y moth, Autographa gamma, a migratory pest in Sweden infesting sugar beets in Skåne.
