Project 2 Photoperiodism: circadian photoreception driving body composition changes in migratory Lepidoptera
To investigate the circadian and photoperiodic inputs in migratory Lepidoptera. Migratory animals typically undergo dramatic changes in body composition before migration. In multivoltine butterflies and moths, these changes occur in the generations that prepare for migration and typically encompass increase in fat body size and thoracic flight muscles. Such annual changes in behaviour and body composition are seasonally synchronized by photoperiod. The photoreceptive pathway and the role of the circadian system are only partly described in the diurnal migratory Monarch butterfly, but are lacking in nocturnal moths. In this project we will describe the photoreceptor system involved in the photoperiodic response in diurnal and nocturnal Lepidoptera at different life stages, such that spectral composition of light can be optimized to induce changes in body composition. Sensitivity in photoperiod response mechanisms will be described by comparing a nocturnal moth and diurnal butterfly. Autographa gamma (moth) and Pieris brassicae (butterfly) are the first choice since they can be easily raised on cabbage and are both multivoltine migratory species. Photoperiod sensitive life cycle stages will be established and will be subsequently used to establish spectral sensitivity of the photoperiodic response leading to adaptive changes in body composition. The circadian involvement in the photoperiodic body composition response will be established by knockdown or CRISPR-Cas9 genetic manipulation.
