Abstract

1. 1. Male crickets Gryllus bimaculatus show a drastic change in circadian rhythm from nymphal diurnality to adult nocturnality, in association with an increase in activity level several days after the imaginai moult. 2. 2. The corpora allata implantation into male 7th or 8th instar nymphs produced supernumerary instar nymphs in about 30% of the implanted animals, but did not affected the normal development in the remaining animals. 3. 3. The majority of the supernumerary instar nymphs were diurnal and sexually inactive, although their internal reproductive organs appeared to be fully mature. 4. 4. The supernumerary instar nymphs became nocturnal with an increase in activity level several days after the imaginai (9th) moult. 5. 5. The roles of the nervous system in the regulation of the rhythm reversal are discussed.
