Mark Bluemke David Tkache Ovipositing preferences in Manduca Sexta. Plant preference based on chemosensory or visual cues? Materials Manduca sexta Tobacco plants Tomato plants Milkweed (any non-preferred plant based on availability) Week 12: observe ovipositing behavior with intact antennae Week 13: observe behavior with antennae intact Week 14: observe behavior with antennae removed Week 15: observe behavior with antennae removed Week 16: observe behavior with antennae removed 1. It is well documented that the hawkmoth has a preference to oviposit onto plants that are their primary food such as tobacco plants. We would like to examine which cue is more important for site preference, chemosensory or visual. 2. Manduca prefer tobacco, then tomato plants. If the chemosensory cue is deprived, will that change oviposition choice? We will have a plant that is not of top choice for the hawkmoth and see if the hawkmoth chooses this plant more often after removal of antennae. 3.
