Ips Calligraphus

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.

Population Numbers

AbstractIps grandicollis (Eichhoff) was first recorded from Jamaica in 1978 and has become a potential pest in Pinus plantations in the island. Its distribution there is determined by the occurrence of suitable food, but not by altitude or rainfall. Developmental mortality due to predators, parasites, and resin did not limit population numbers within logs: control resulted ultimately from competition among egg-laying females and among larvae for space in suitable logs. However, when the entire Jamaican population was considered, dispersive loss of adults played a major part in the limitation of numbers. A cyclic budget revealed that a minimum of 44% of the population was lost during dispersal. Dispersive loss in the males (77.3%) was higher than that in the females (35.4%), and this difference may be related to the primary role of the males in finding suitable logs.

Research Avenue

Microbial symbionts are nowadays considered of pivotal importance for animal life. Among the many processes where microorganisms are involved, an emerging research avenue focuses on their major role in driving the evolution of chemical communication in their hosts. Volatiles of bacterial origin may underlie chemical communication and the transfer of social information through signals, as well as inadvertent social information. We reviewed the role of microorganisms in animal communication between conspecifics, and, because the microbiome may cause beneficial as well as deleterious effects on their animal hosts, we also reviewed its role in determining the outcome of the interactions with parasites and predators. Finally, we paid special attention to the hypothetical role of predation and parasitism in driving the evolution of the animal microbiome. We highlighted the novelty of the theoretical framework derived from considering the microbiota of animals in scenarios of communication, parasitism, and predation. We aimed to encourage research in these areas, suggesting key predictions that need to be tested to better understand what is one of the main roles of bacteria in animal biology.
