| Research Abstract |
Influences of neural re-construction and behaviors in a silk moth with expression of supernumerary prolegs were investigated. In mutant individuals, the proleg motor neurons were appeared in the larval second abdominal ganglion, and additional mechanosensory hairs were distributed in the second abdominal segment. Analyses of the walking pattern with prolegs suggest adjustments of walking cycles to maintain a particular length of the cycle period. An abnormal structure of the ganglion in mutant larvae inhibited ganglionic shortening and fusion in metamorphosis, resulted in separated metathoracic ganglion and influenced mating behaviors in adult males.
