Phenotypic traits of laboratory-housed field crickets (Gryllus bimaculatus) bred from parents with a range of ages

Crickets were housed in individual boxes (approximately 18x10x7cm) from hatching . All individuals were kept at 28 degrees Celsius. Development time and lifespan data were obtained by weekly survival and adult emergence checks. Body mass was recorded to the nearest microgram using a calibrated balance. Weakly checks were done to record the date of adult emergence or death. Individuals had access to food (dried grass pellets - rabbit food from Science Selective) and water ad libitum. The data were entered in an Access data base and subsequently exported as csv file.
