Effects of light, temperature, and feeding status on flight initiation in postdiapause Colorado potato beetles (Coleoptera: Chrysomelidae)
Environmental Entomology 19 (2), 281-285
Abstract: Flight initiation in postdiapause Colorado potato beetles, Leptinotarsa decemlineata (Say), occurred at temperatures as low as 15°C in field trials, and the percentage of initiation increased gradually to 100% at 20°C.
Flight initiation and behavior were different between starved and fed beetles; starved beetles initiated more flights to greater heights and over longer distances. In wind tunnel studies, flight initiation increased with increasing light intensity.
