“…For example, coevolution has been invoked to explain the evolution of specialization in herbivorous insects (Dethier 1954;Krieger et al 1971;Feeny 1975;Smiley 1978), the evolutionary elaboration of shells in marine mollusks (Vermeij 1987(Vermeij , 1993, and the generation of diversity in plant secondary chemistry (Ehrlich and Raven 1964;Berenbaum 1983) and morphology (Janzen 1969;Gilbert 1971Gilbert , 1975Rausher 1981;Janzen and Martin 1982). Examples of coevolution may be divided into two main groups reflecting the nature of the interaction between the coevolving species.…”

Two modes of host–enemy coevolution

The process of coevolution between host and enemy has traditionally been viewed as an evolutionary arms race between resistance and counterresistance. The armsrace metaphor of coevolution is widely accepted because it explains the evolution of many characters in species involved in host-enemy interactions. However, molecular work in plant-pathogen systems suggests a coevolutionary interplay between plant recognition of an attacking pathogen and pathogen evasion from recognition. We refer to this process as information coevolution, and contrast this with arms race coevolution to show that these two processes result in very different patterns of host resistance and enemy virulence at the population level. First, information coevolution results in a lower proportion of hosts that are susceptible to enemy attack within a population. Second, information coevolution produces a pattern of local maladaptation of enemy on host, a naturally occurring phenomenon that is difficult to explain under arms race coevolution. We then conduct a literature review to survey the empirical support for either mode of coevolution using the predicted patterns of host resistance and enemy virulence. Evidence supports both modes of coevolution in plant-enemy interactions, whereas no support is found for information coevolution in vertebrate-parasite and invertebrate-parasite systems.

Five populations derived from a composite, genetically heterogeneous strain of the flour beetle, Tribolium castaneum, were selected on new diets (dog food, powdered rice, brewers' yeast, wheat flour and oats) for 13 -16 generations. A control population was reared on the standard medium (flour + 5°7o brewers' yeast). Adaptedness was measured in terms of (1) fitness parameters (survival and developmental time), (2) amylase activity levels (amylase is an essential digestive enzyme in flour beetles) and (3) food preference behavior.There were significant temporal trends in fitness components in the selected populations. Survival was initially low but increased with time. Developmental time decreased in later generations of selection. The control population showed the smallest increase in survival and no decrease in developmental time. When tested at the end of the experiment, survival to adulthood of eggs from each selected population on its selective diet was higher than that of control eggs. On the standard medium, no differences in survival among populations were detected. These results suggest that the improvement in fitness may indicate adaptation to the new environments created by the different food media.Amylase activity also increased temporally in 4 selected populations but not in the control (nor on unenriched wheat flour). Tests at the end of the experiment, however, suggest that this increase was, in large part, environmentally induced. We found no evidence that an adaptive genetic change in amylase regulation took place.There were no temporal trends in food-preference behavior during the selection process.

“…In phytophagous insects, the favoured host plant is something 'lived on'with the whole community as such being selected, so that the interaction between the host and the insect is direct and preference by the insect being towards survival, food and the community as a whole (Dethier 1954). In mycophagous thrips, the situation is further complicated in that the interaction is triangular, involving the insect species, the preferred microhabitat where the insect 'lives' and the fungal species that is fed upon.…”

Patterns of fungal resource utilization and feeding range in some mycophagous Tubulifera (Insecta: Thysanoptera)

Adaptive specialization in terms of survival due to diverse fungal feeding preferences and seasonal dispersal is indicated in the sporophagous species Loyo/aia indica (Anan). Feeding behavioural patterns of six species of mycophagous Tubulifera reflect diversity in fungal resource utilization and feeding range. Influence of fungal food on the strategies of survival. reproduction and aggregation has been discussed.
