Amphicerus bicaudatus, known generally as the apple twig borer or grape cane borer, is a species of horned powder-post beetle in the family Bostrichidae. [1] [2] It is a pest of cultivated orchard trees as well as grapes and other tree species. [3]
Adults are long and cylindrical, about 6 to 13 millimeters long. Color can range from reddish brown to black. Larvae are white with a brown head and mandibles, about 10 millimeters long. [3]
Allen et al., 1991 finds some periodicity and some chaos in its population dynamics while Allen et al., 1993 finds only periodicity and quasiperiodicity. [4] Both examine the interaction of beetle, insecticide, cane removal, and the grapevine host. [4] The 1991 model shows some chaotic solutions while 1993 never does. [4]
