Kinematics of phonotactic steering in the walking cricket Gryllus bimaculatus (de Geer).
Female crickets, Gryllus bimaculatus, are attracted by the male calling song and approach singing males; a behaviour known as phonotaxis. Even tethered females walking on a trackball steer towards a computer-generated male song presented from their left or right side. High-speed video analysis showed how this auditory-evoked steering was integrated with walking. Typically all the front and midd...
متن کاملHyperacute Directional Hearing and Phonotactic Steering in the Cricket (Gryllus bimaculatus deGeer)
BACKGROUND Auditory mate or prey localisation is central to the lifestyle of many animals and requires precise directional hearing. However, when the incident angle of sound approaches 0° azimuth, interaural time and intensity differences gradually vanish. This poses a demanding challenge to animals especially when interaural distances are small. To cope with these limitations imposed by the la...
متن کاملMechanisms underlying phonotactic steering in the cricket Gryllus bimaculatus revealed with a fast trackball system.
Phonotactic steering behaviour of the cricket G. bimaculatus was analysed with a new highly sensitive trackball system providing a spatial and temporal resolution of 127 microm and 0.3 ms, respectively. Orientation to artificial calling songs started at 45 dB SPL, it increased up to 75 dB SPL and then saturated. When exposed to two identical patterns of different intensity, crickets significant...
متن کاملInfluence of Electric Bulb Light Color and Type on the Attraction of Two Spotted Cricket (Gryllus bimaculatus De Geer)
Aside being a key nocturnal Agricultural pest, the two spotted cricket is an important source of protein for humans and livestock. While control is largely by synthetic pesticides, collection is majorly through hand picking and pouring of water into their burrows. In this study, we determined their phototactic response to LED and incandescent bulb light of different colours. An experiment was s...
متن کاملOlfactory learning in the cricket Gryllus bimaculatus.
The olfactory learning capability of the cricket Gryllus bimaculatus was studied. Crickets were deprived of drinking water for 4 days and were individually trained to associate peppermint with water and vanilla with NaCl solution. Their odour preference was tested before and after training by allowing them to choose between peppermint or vanilla sources. The time spent visiting each source serv...
