AbstractIps calligraphus (Germar) has previously been recorded from Jamaica but this is the first record of Ips grandicollis (Eichhoff) in the island. In Jamaica, both bark beetles attack 5 species of Pinus, 4 of which had not been previously recorded. The beetles thrive mainly on freshly cut logs and weakened trees, but recently they have been rising to economic importance in plantations. Successful attack on live trees is enhanced by mass aggregation of dispersing adults during invasion. Some adults may re-emerge after a phase of oviposition and disperse to new food sources. There is degeneration of flight muscles during oviposition, and regeneration to allow for another dispersive flight. In I. calligraphus attacking Pinus caribaea there was a mean of 26.74 ± 6.86 (mean ± SE) eggs per gallery, while in I. grandicollis there was 19.29 ± 3.04. The proportion of females at emergence was 0.57 ± 0.03 and 0.05 ± 0.02 in I. calligraphus and I. grandicollis, respectively.

Potential Use

As a group, arthropod natural enemies have been shown to substantially reduce within-tree pine bark beetle populations. However, little is known about the impacts of individual species on bark beetle mortality. In a controlled laboratory study, we measured the effects of two predaceous histerid species, Platysoma parallelum (Say) and Plegaderus transversus (Say), on Ips calligraphus (Germar) and Ips grandicollis (Eichhoff) brood mortality. Platysoma parallelum was found to have a greater impact on I. grandicollis mortality than Ple. transversus when only one histerid and prey species were present. No significant differences in I. calligraphus mortality were observed for either of the two histerid species. More I. grandicollis brood was killed per introduced Pla. parallelum adult than per introduced Ple. transversus adult likely as a result of the larger size and biomass requirements of Pla. parallelum. The results of this experiment indicate that histerids, by themselves, have the ability to lower within-tree bark beetle populations and could have potential use in a bark beetle biological control program.

Species Groups

Many forms of polygyny are observed across different animal groups. In some species, groups of females may remain with a single male for breeding, often referred to as “harem polygyny”. The environment and the amount of habitat available for feeding, mating and oviposition may have an effect on the formation of harems. We aimed to determine how the surrounding environment (a harvested or unharvested pine plantation) and availability of local substrate affect the harems of the bark beetle, Ips grandicollis (Coleoptera: Curculionidae: Scolytinae). In a harvested pine plantation with large amounts of available habitat, the population density of these beetles is much higher than in unharvested plantations. We found the number of females per male to be significantly greater in the harvested plantation than the unharvested one. Additionally, the amount of substrate available in the immediate local vicinity (the number of logs in replicate piles) also influences the number of beetles attracted to a log and size of individual harems. We also examined how females were distributing themselves in their galleries around the males’ nuptial chamber, as previous work has demonstrated the potential for competition between neighbouring females and their offspring. Females do not perform clumping, suggesting some avoidance when females make their galleries, but they also do not distribute themselves evenly. Female distribution around the male’s nuptial chamber appears to be random, and not influenced by other females or external conditions.

Host Resource

AbstractResults of a field experiment indicate that adults of the pine weevil Hylobius pales (Herbst) respond to pheromones of bark beetles. Each sex of H. pales was more attracted to traps baited with the combination of a pine bolt infested with male Ips calligraphus Germar plus the synthetic Dendroctonus Erichson pheromones frontalin and exo-brevicomin, than to traps baited with pine bolts alone. The combined numbers of male and female H. pales caught in traps baited only with Ips calligraphus-infested bolts were significantly greater than numbers caught in traps baited with uninfested control bolts. The attraction of H. pales to bark beetle pheromones may represent a kairomonal response in which weevils exploit semiochemicals from other species that signify a suitable host resource.

AbstractIps calligraphus (Germar), I. ponderosae Swaine and I. interstitialis (Eichhoff) represent one variable species with the oldest name, Ips calligraphus (Germar) taking precedence. Ips calligraphus can always be recognized by the six spines on each side of the declivity. All other species in North America have less than six spines on each side.

Growth And Reproduction

Bark beetles are associated with diverse assemblages of microorganisms, many of which affect their interactions with host plants and natural enemies. We tested how bacterial associates of three bark beetles with various types of host relationships affect growth and reproduction of their symbiotic fungi. Fungi were exposed to volatiles from bacteria in an arena that imposed physical separation but shared airspace. We also exposed fungi to vapors of the host compound, α-pinene, and to combinations of bacterial volatiles and α-pinene. Bacterial volatiles commonly stimulated growth of Leptographium procerum (W.B. Kendr.) M.J. Wingf. and Grosmannia clavigera (Rob.-Jeffr. & R.W. Davidson) Zipfel, Z.W. de Beer & Wingf., which are symbiotic fungi of Dendroctonus valens LeConte and Dendroctonus ponderosae Hopkins, respectively. They less commonly stimulated growth of Ophiostoma ips (Rumbold) Nannf., which is associated with Ips grandicollis Eichhoff. Some bacteria inhibited L. procerum, Ophiostoma montium (Rumbold) von Arx (another associate of D. ponderosae), and O. ips. Bacteria greatly stimulated spore production of symbionts of D. valens and D. ponderosae. α-Pinene strongly affected some of these relationships, causing amplification, reduction, or reversal of the interactions among the bacteria and fungi. Our results show that some bacteria associated with bark beetles directly affect fungal symbionts and interact with tree chemistry to affect fungal growth and sporulation. The strongest effects were induced by bacteria associated with beetles adapted to attacking living trees with vigorous defenses, and on fungal reproductive structures.
