“…Plant specialists show congenitally fixed responses to plant cues, while plant generalists, especially those that are specialists at the herbivore level, learn to respond to plant volatiles and to other environmental cues that are associated with herbivore presence (e.g. 80,176,192,195,196). Such environmental cues could actually involve cues from intercropped plants that are closely and predictably associated with the plants that accommodate their victims.…”

KEY WORDS:predators, parasitoids, searching behavior, learning, evolutionary theory, integrated pest management PERSPECTIVES AND OVERVIEW Parasitoids and predators of herbivores have evolved and function within a multitrophic context. Consequently, their physiology and behavior are influenced by elements from other trophic levels such as their herbivore victim (second trophic level) and its plant food (first trophic level) (126). Natural enemies base their foraging decisions on information from these different trophic levels, and chemical information plays an important role. This review is restricted to the ecology of chemical information from the first and second trophic levels. The importance of so-called infochemicals, a subcategory of semiochemicals, in foraging by parasitoids and predators has been well documented (e.g. reviewed in 31,78,111,183,185), and we do not intend repeat the details. But because of a lack of testable hypotheses, all this research is conducted rather haphazardly: the total puzzle of infochemical use has not been solved for any natural enemy species. Here we approach the use of infochemicals by natural enemies from an evolutionary and ecological standpoint. Our basic concept is that information from the first and second trophic levels differs in availability and in reliability, a difference that shapes the way infochemicals are used by a species. We generate hypotheses on (a) 141

“…Studies on the foraging behavior of parasitoids illustrate the potential importance of vision for host-and prey-finding by natural enemies. Not only do parasitoids show innate preferences for specific visual cues but they are also able to learn cues that are consistently associated with the presence of their hosts (Arthur, 1966;Weseloh, 1972Weseloh, , 1986Wardle, 1990;Wardle and Borden, 1990;Ma et al, 1992; Wä ckers, 1994; Wä ckers and Lewis, 1994).…”

“…In one case, no preference for blue over orange was found (Exeristes roborator F. ;Wardle 1990). Other studies reported innate preferences for blue over yellow (Itoplectis conquisitor Say; Arthur 1966; Pimpla instigator F.; Schmidt et al 1993), for yellow over green, red, black, and blue (Diachasmimorpha longicaudata Ashmead; Messing and Jang 1992) and for yellow over green (Aphidius ervi Haliday; Battaglia et al 2000).…”

“…However, these studies also did not evaluate the potential effect of achromatic cues on the choices of the parasitoids. Wardle (1990) showed that Exeristes roborator (F.) (Ichneumonidae) failed to learn reßectance intensity of light and dark gray host microhabitat models while succeeding in wavelength learning. Evidence for true color vision in hymenopteran parasitoids is scarce.…”

Chromatic and achromatic plant cues are expected to be particularly important for parasitoids of endophytic pupal hosts, because these stages do not feed and therefore avoid volatile emission caused by plant tissue damage. Endophytic feeding can cause discoloration or desiccation, leading to changes in color and/or brightness of infested plant parts that may be visually detected by parasitoids. The role of color cues in the host-Þnding behavior of parasitoids is poorly understood, and the visual system of most parasitoid species has not yet been investigated. We studied color discrimination ability and innate color preferences in the pupal parasitoid Pimpla turionellae (L.) (Hymenoptera: Ichneumonidae) during location of concealed hosts. Responses to combinations of yellow and blue bands of different reßectance intensities were investigated on cylindrical models of plant stems. The parasitoidÕs reaction to these chromatic cues was evaluated by scoring the number of ovipositor insertions into the colored bands. Female parasitoids discriminated blue from yellow irrespective of total reßectance and inserted their ovipositors signiÞcantly more often into the blue area. True color vision is demonstrated for the examined species, and responses to chromatic cues are discussed in relation to their importance for host location in parasitoids. Results of this study and of our previous work suggest that P. turionellae uses contrasts (chromatic or achromatic) rather than speciÞc color characteristics in visual host location.
