The results of these studies demonstrate that many parasitoids do orient to factors from the host's food.…”

The coevolution of a predator and its prey suggests that the prey is selected for predator avoidance and escape while the predator is selected for more efficient prey-finding and capture. The predator attacks and consumes its host and, thus being successful, would be expected to propagate. The parasite-host relationship is a similar reciprocating evolutionary relationship with one important difference--the host should not be killed. The parasite must not only locate the host but must constantly adapt to a developing and changing host, a situation resulting in a closely interwoven relationship. The continued development of a host in accord with the evolutionary development of the host species is of benefit to the parasite. It is probably advantageous for the parasite to evolve towards a condition where the parasite has a minimal affect on the host species. This would insure the continued existence of a viable host population.The parasitoid-host relationship is akin to the predator-and parasite-host relationship, but with some unique aspects. The term parasitoid is used for arthropods where the egg and early larval stages are parasitic, but where the host is eventually killed. The adult is free living. In the parasitoid-host relationship, the parasitoid must not only locate the host, but must utilize the host for the progeny's benefit. Once the host has been parasitized, the parasitoid's progeny grow and develop at the expense of the host; ultimately killing the host. The host's future development is only of importance to the parasitoid. Thus the evolutionary strategy of the parasitoid is different from that of a parasite or predator. The parasitized host can no longer be considered as a member of the host species, but must be viewed as a container for the parasitoid. The evolutionary development of the parasitized host towards a

“…In numerous studies since (e.g., Taylor, 1932;Zwölfer and Kraus, 1957;Salt, 1958;Harrington and Barbosa, 1978), predators and parasitoids were found more on one plant species than another. That plant volatiles may be responsible for such differential attractiveness was apparent from studies by, among others, Monteith (1955), Arthur (1962), Flint et al (1979), and Elzen et al (1984). These studies considered the importance of the plant only at the level of habitat locations, as defined by Vinson (1981).…”

“…Olfactory responses to the host plant are common and parasites may show preferences between species. For instance, Itoptectis conquisitor (Hymenoptera: Ichneumonidae) is attracted to the odour of Scots pine (Pinus sylvestris) more than that of the Red pine (P. resinosa) so that the former is more heavily parasitised (Arthur 1962). Parasitism also may be influenced by physical attributes of the plant, such as surface texture in the case of Trichogramma (Flanders 1937).…”

“…Hosts in or on differing parts of the same plant may vary in vulnerability. Females of I. conquisitor are unable to parasitise pupae in buds protected by needles, and parasitism was higher in small than in large buds (Arthur 1962). Carnegie (1980) considered the growth habits of host plants to be a factor causing the low levels of parasitism by Ootetrartichus beatus (Hymenoptera: Eulophidae) and Oligosita numiciae (Hymenoptera: Trichogrammatidae) in sugarcane compared to other host plants.…”

Percentage parasitism of the eggs of the passion vine hopper (Scolypopa australis) by Centrodora scolypopae varies with the host plant. The depth of the S. australis eggs below the surface was measured on Pteridium aquilinum var esculentum, Rubus fruticosus agg., Berberii darwinii, Polygonurn conuoluulus, Coriuria arborea and Cyathea sp., and related to the observed parasitism. It was found that egg depth varied between plant species, ranging from 0.30 +-.08 mm in P. aquilinum to 0.48 f .O1 mm in R. fruticosus and was inversely related to level of parasitism. Differing parts of the same plant varied in parasitism levels, with the shallow eggs on the thorns of B. darwinii and racemes of C. arborea having higher levels of parasitism than those in the stems. The average length of the C. scolypopae ovipositor was 0.60 20.1 mm. Many eggs laid in plants with soft stems were beyond the reach of the parasite, whereas host eggs laid at shallow depths in hard plant tissues were accessible and thus were parasitised heavily.
