Effects of host tree species on attractiveness of tunneling pine engravers, Ips pini, to conspecifics and insect predators
Journal of Chemical Ecology 26 (4), 823-840
Abstract: The effect of host tree species on the attractiveness of tunneling Ips pini to flying beetles and their insect predators in Wisconsin was investigated. Tree species influenced the flight response of both predators and prey in the same rank order. Ips pini and its major predators, Thanasimus dubius and Platysoma cylindrica, were more attracted to I. pini males boring into bark-phloem disks of Pinus strobus L. than Pinus banksiana Lamb, and least attracted to I. pini males boring into bark-phloem disks of Pinus resinosa. Sources of within-tree, between-tree, and between-species variation in the degree of attraction elicited by tunneling beetles were quantified. A bioassay for evaluating host tree effects on pheromone based communication among bark beetles under conditions of controlled beetle entry was developed. Possible mechanisms of host species effects on the dynamics of predator and prey interactions in bark beetle ecology are discussed.
