“…A clerid predator in Europe, Thanasimus formicarius preys on I. typographus of Norway spruce and T. piniperda of Scots pine and is also attracted to a-pinene and other monoterpenes from these conifers (Schroeder, 1988;Schroeder and Lindelow, 1989). The dipteran parasites Medetera aldrichii of D. pseudotsugae and M. bistriata of D. frontalis are attracted to the host-tree monoterpene, a-pinene, presumably aiding in their location of attacked trees (Williamson, 1971;Fitzgerald and Nagel, 1972). These plant monoterpenes are attractive to many bark beetles, or are synergists of attractive pheromone components (see section 2.3).…”

“…The wealth of knowledge on bark beetle pheromones (Wood, 1982;Birch, 1984;Borden, 1984) has caused a boom in chemical knowledge of kairomones that attract their predators (Vit6 and WiUiamson, 1970;Billings and Cameron, 1984;Chatelaln and Schenk, 1984;Heuer and Vit6, 1984;Payne et al, 1984). In addition, several tree terpenes whose release is increased by herbivore damage, and that function as synomones in plant-predator interactions, have been identified (Fitzgerald and Nagel, 1972;Baisier et al, t988). Similarly, Aldrich et al (1986) identified a pheromone of a stink bug and showed that it attracts its predator, the eastern yetlowjacket.…”

Abstract--To understand the role of allelochemicals in predator-prey interactions it is not sufficient to study the behavioral responses of predator and prey, One should elucidate the origin of the allelochemicals and be aware that it may be located at another trophic level. These aspects are reviewed for predator-prey interactions in general and illustrated in detail for interactions between predatory mites and herbivorous mites. In the latter system there is behavioral and chemical evidence for the involvement of the host plant in production of volatile allelochemicals upon damage by the herbivores with the consequence of attracting predators. These volatiles not only influence predator behavior, but also prey behavior and even the attractiveness of nearby plants to predators. Herbivorous mites disperse away from places with high concentrations of the volatiles, and undamaged plants attract more predators when previously exposed to volatites from infested conspecific plants rather than from uninfested plants. The latter phenomenon may well be an example of plant-to-plant communication. The involvement of the host plant is probably not unique to the predator-herbivore-plant system under study. It may well be widespread since it makes sense from an evolutionary point of view. If so, prospects for application in pest control are wide open. These are discussed, and it is concluded that crop protection in the future should include tactics whereby man becomes an ally to plants in their strategies to manipulate predator-prey interactions through allelochemicals.

“…A similarly intriguing case is that of the dolichopodid fly, Medetera aldrichii, whose larvae are predators of bark beetle larvae. Host tree-produced c~-pinene induces the female predators to oviposit under bark scales (Fitzgerald & Nagel 1972). In the related M. bistriata, longrange attraction proved to be due to a mixture of c~-pinene and prey pheromones, frontalin and trans-verbenol (Williamson 1971), which would provide the searching flies with indications as to prey location and the proper timing of attack.…”

Orientation ofRhizophagus grandis (Coleoptera: Rhizophagidae) to oxygenated monoterpenes in a species-specific predator-prey relationship

et al. 1992

SummaryThe predator, Rhizophagus grandis, is linked to its specific prey, Dendroctonus micans, by semiochemical signals regulating oviposition and long range orientation. A mixture of simple oxygenated monoterpenes [(-)-fenchone, (-)-pinocamphone, rac. camphor, terpinene-4-ol, borneol, fenchol and verbenone], identified from the frass of D: micans has been found to be extremely active in a flight windtunnel as a long-range attractant for the predator. The mixture elicited 84 07o of the response to larval frass of the prey. Excluding pinocamphone from the mixture did not influence its activity. Also, changing the absolute configurations of some of the components (fenchol, terpinene-4-ol and borneol) did not influence the predators' response. However, the addition of (-)-a-terpineol increased the attractivity of the synthetic blend to almost that of larval frass of the prey. Ecological implications of the identified semiochemicals and their use in pest management are discussed.
