Summary Virgin Teleogryllus commodus females show rhythmic locomotor activity in light-dark (LD) and constant light (LL) conditions. A taped 3-h calling song stimulates them into further walking, and they lay few eggs. Successful mating suppresses or reduces circadian-controlled walking, but in LL-conditions the free-run still persists. Mated females no longer respond to the 3-h calling song. The number of eggs laid within 24–72 h after insemination increases, and the three effects of mating occur independently of one another. The possible physiological basis of these changes and their ecological and behavioral significance under field conditions are discussed. 相似文献

Summary Locomotor activity of the Teleogryllus commodus is under circadian control, with LL=25.3 h and DD=23.4 h. In LD 12:12 h, running occurs either exclusively during darkness (57%), mainly in the dark phase (35%), or with substantial activity peaks in both phases (8%). For oviposition, LL>24 h and DD<24 h; in LD 12:12 h, 80% of the studied deposited their eggs mainly during the light phase and 20% primarily during darkness. In the discussion, a temporal correlation between stridulation, spermatophore formation, and locomotion, and oviposition is established, which serves to make an encounter and mating between the sexes as likely as possible.Dedicated to Prof. Dr. M. Gersch on the occasion of his 70th birthday 相似文献

Summary The temporal relationship between male-calling and female-walking of Teleogryllus ocearicus has been studied. Both behaviors are under circadian control. A comparison of singingactivity under controlled environmental conditions and in the field at LD 13.75:10.25 h revealed that in spote of the very different situations, calling occurred during darkness; the times of onset, termination of singing and the calling quantity agreed as well. However, significant individual differences in singing activity were observed in either environment, and for specific males on consecutive nights.This paper is dedicated to Mr. Richard B. Gump, whose generosity has made the described research possible and the South Pacific Biological Research Station a reality 相似文献

Summary The calling song of the -cricket, Teleogryllus commodus, attracts for mating. Both calling and -locomotor activity are under circadian control and the behaviors occur approximately at the same time. Daily playback of calling songs for 3–12 h in constant light failed to entrain -running. Instead, calling acts as an external stimulus which can release -locomotion at any time of the 24-h period, while the clock-induced activity continues to run freely. The stimulatory effect of the calling song causes flexible extension of -locomotor activity, but a subsequent restorative period is necessary. The ecological consequences of acoustical stimulation are discussed. 相似文献
