“…An additional condition for transitioning from the delicacy category is production on a sufficiently large scale, for which in which recent years important investments were made. Currently the largest commercial-scale house cricket production for human consumption is located in Asia and Africa [17,22], but throughout the world there are commercial producers also for zoo and pet food purposes [45] and for research use in laboratories [197]. Recently a large-scale industrial cricket farm was opened in Canada, with 12,000 metric tons annual capacity [198].…”

Lifelong exposure to artificial light at night impacts stridulation and locomotion activity patterns in the cricketGryllus bimaculatus

Living organisms experience a worldwide continuous increase in artificial light at night (ALAN), negatively affecting their behaviour. The field cricket, an established model in physiology and behaviour, can provide insights into the effect of ALAN on insect behaviour. The stridulation and locomotion patterns of adult male crickets reared under different lifelong ALAN intensities were monitored simultaneously for five consecutive days in custom-made anechoic chambers. Daily activity periods and acrophases were compared between the experimental groups. Control crickets exhibited a robust rhythm, stridulating at night and demonstrating locomotor activity during the day. By contrast, ALAN affected both the relative level and timing of the crickets' nocturnal and diurnal activity. ALAN induced free-running patterns, manifested in significant changes in the median and variance of the activity periods, and even arrhythmic behaviour. The magnitude of disruption was light intensity dependent, revealing an increase in the difference between the activity periods calculated for stridulation and locomotion in the same individual. This finding may indicate the existence of two peripheral clocks. Our results demonstrate that ecologically relevant ALAN intensities affect crickets’ behavioural patterns, and may lead to decoupling of locomotion and stridulation behaviours at the individual level, and to loss of synchronization at the population level.
