Neuroethology of oviposition behavior in the moth Manduca sexta.
Olfactory cues play decisive roles in the lives of most insect species, providing information about biologically relevant resources, such as food, mates, and oviposition sites. The nocturnal moth Manduca sexta feeds on floral nectar from a variety of plants (and thus serves as a pollinator), but females oviposit almost exclusively on solanaceous plants, which they recognize on the basis of olfa...
متن کاملPlant species- and status-specific odorant blends guide oviposition choice in the moth Manduca sexta.
The reproductive success of herbivorous insects largely depends on the mother's oviposition preference. In nocturnal insects, olfaction is arguably the most important sensory modality mediating mate finding, foraging, and host location. In most habitats, gravid females select among a number of plants of varying suitability, yet assessment of the neuroethological mechanisms underlying odor-guide...
متن کاملThe Organization of Flight Motoneurones in the Moth, Manduca Sexta
The morphology and the innervation of the main wing depressor muscles have been studied. The motoneurones to these muscles have dendrites ipsilateral to the muscle they innervate and located in the dorsal neuropile. With the exception of one motoneurone, to the dorsal longitudinal muscle, all motoneurone cell bodies are ipsilateral to the muscle they innervate. The morphologies of individual co...
متن کاملTemporally staggered glomerulus development in the moth Manduca sexta.
Glomeruli, neuropilar structures composed of olfactory receptor neuron (ORN) axon terminals and central neuron dendrites, are a common feature of olfactory systems. Typically, ORN axons segregate into glomeruli based on odor specificity, making glomeruli the basic unit for initial processing of odorant information. Developmentally, glomeruli arise from protoglomeruli, loose clusters of ORN axon...
متن کاملNeural correlates of behavior in the moth Manduca sexta in response to complex odors.
With Manduca sexta as a model system, we analyzed how natural odor mixtures that are most effective in eliciting flight and foraging behaviors are encoded in the primary olfactory center in the brain, the antennal lobe. We used gas chromatography coupled with multiunit neural-ensemble recording to identify key odorants from flowers of two important nectar resources, the desert plants Datura wri...
