Document Summary
Neuron: has dendrite (receives info) and axon (sends info). Sensory systems: cuticular modifications and projections that detect stimuli (hair, setae). Tympanal: membrane linked to chordotonal organs, often associated with air-filled sacs to enhance sound. Non-tympanal: trichoid sensilla sensitive to nearby sound vibrations, air currents. Tymbal: elastic cuticle produces sound by muscular relaxation and distortion. Mullerian mimicry: predators learn to avoid red/black spp. that are chemically protected. Bastian mimicry: looks like protected organism but no chemical defense. Moths were sampled, found distasteful, no longer eaten. When clicking was removed, moths were sampled again (and again realized they were inedible). Receptors in antennae, mouth, legs, ovipositor trap chemicals in pores. Pheromone: scent to be received by individual(s) of the same spp. (sex, aggregation, spacing, alarm). Kairomone: benefit receiver but disadvantage producer (e. g. host compound attracts parasitoid). Allomone: benefits producer but not the receiver (e. g. compounds that show distastefulness). Synomone: benefits both producer and receiver (e. g. plant compounds that attract parasitoids of herbivores).
