Aulacophora nigripennis adults have winter diapause and accumulate myo-inositol during winter. To elucidate the relationship between diapause state and myo-inositol metabolism, two kinds of juvenile hormone analog (JHA), methoprene and pyriproxyfen, were topically applied to the diapausing beetles and subsequent changes in diapause state and myo-inositol content were observed. Application of JHA terminated diapause and also inhibited myo-inositol accumulation. These observations suggest that diapause state and myo-inositol content of this beetle are regulated by the JH endocrine system, although it remains unsolved whether the disappearance of myo-inositol was caused by direct action of JH or by an indirect effect accompanied by diapause termination.
