“…When experiments were made on established and novel host plants, the results from previous experiments on other herbivorous insects indicate positive or no genetic correlation (Rausher, 1984b;Via, 1984;Hare & Kennedy, 1986;James et al, 1988;Karowe, 1990;Fox, 1993), and significant genetic variation in growth performance on each plant (Rausher, 1984b;Hare & Kennedy, 1986). These and the present results suggest that host expansion may not be constrained genetically at least at the initial stage of host range evolution.…”

“…However, negative correlations have been found in only a limited number of species (Gould, 1979;Fry, 1990;Via, 1991;Mackenzie, 1996). Instead of a negative genetic correlation, positive or no genetic correlations were commonly reported in the previous studies (Rausher, 1984b;Via, 1984;Hare & Kennedy, 1986;Futuyma & Philippi, 1987;James et al 1988;Jaenike, 1989;Karowe, 1990;Fox, 1993;Lu et al 1997). To account for this general lack of negative genetic correlations, it has been suggested that antagonistic pleiotropic effects reflecting underlying constraints may be masked by several factors that increase genetic variation in general performance across hosts (Service & Rose, 1985;Houle, 1991;Price & Schluter, 1991;Fry, 1993).…”

Genetic trade-offs in host plant use are thought to promote the evolution of host specificity. Experiments on a range of herbivorous insects, however, have found negative genetic correlation in host plant use in only a limited number of species. To account for the general lack of negative genetic correlation, recent hypotheses advocate that different stages in evolution of host use must be distinguished: initial performance on a novel host in comparison with the established host, and performance on both hosts after the insect population has interacted with both hosts for a long time. The hypotheses suggest that genetic correlation may not necessarily be negative at the initial stage. The present study examines growth performance on both the established and a novel host in a herbivorous ladybird beetle, Epilachna vigintioctomaculata Motschulsky (Coccinellidae, Epilachninae). The results show that traits of growth performance across hosts were positively or neutrally correlated, but there was no evidence of a negative genetic correlation. In addition, significant genetic variance of growth performance on each host was detected, suggesting that E. vigintioctomaculata can potentially respond to selection for increased performance on both plant species. These results and similar results from experiments on other herbivores suggest that host expansion may not be constrained genetically, at least at the initial stage of host range evolution.

“…They are important because they can act as postmating isolating barriers. However, there is surprisingly little empirical support for trade-offs in phytophagous insects (Futuyma and Moreno 1988;Jaenike 1990; for exceptions see Gould 1979;Mitter et al 1979;Fry 1990;Karowe 1990;Via 1991;and Mackenzie 1996). Ifthe current dearth of examples is an accurate reflection of nature, then sympatric speciation via host shifts is an uncommon mode of divergence (Butlin 1987).…”

THE EFFECTS OF WINTER LENGTH ON THE GENETICS OF APPLE AND HAWTHORN RACES OF RHAGOLETIS POMONELLA (DIPTERA: TEPHRITIDAE)

et al. 1997

Abstract.-Host plant-associated fitness trade-offs are central to models of sympatric speciation proposed for certain phytophagous insects. But empirical evidence for such trade-offs is scant, which has called into question the likelihood of nonallopatric speciation. Here, we report on the second in a series of studies testing for host-related selection on pupal life-history characteristics of apple-(Malus pumila L.) and hawthorn-(Crataegus mol/is L. spp.) infesting races of the Tephritid fruit fly, Rhagoletis pomonel/a (Walsh). In particular, we examine the effects of winter length on the genetics of these flies.We have previously found that the earlier fruiting phenology of apple trees exposes apple-fly pupae to longer periods of warm weather preceding winter than hawthorn-fly pupae. Because R. pomonel/a has a facultative diapause, we hypothesized that this selects for pupae with more recalcitrant pupal diapauses (or slower metabolic/development rates) in the apple-fly race. A study in which we experimentally manipulated the length of the prewintering period for hawthorn-origin pupae supported this prediction.If the period preceding winter is important for apple-and hawthorn-fly pupae, then so too should be the length (duration) of winter; the rationale for this prediction is that "fast developing" pupae that break diapause too early will deplete their energy reserves and disproportionately die during long winters. To test this possibility, we chilled apple-and hawthorn-origin pupae collected from a field site near Grant, Michigan, in a refrigerator at 4°C for time periods ranging from one week to two years. Our a priori expectation was that longer periods of cold storage would select against allozyme markers that were associated with faster rates of development in our earlier study. Since these electromorphs are typically found at higher frequencies in hawthorn flies, extending the overwintering period should favor "apple-fly alleles" in both races.The results from this "overwinter" experiment supported the diapause hypothesis. The anticipated genetic response was observed in both apple and hawthorn races, as allele frequencies became significantly more "apple-fly-like" in eclosing adults surviving longer chilling periods. This indicates that it is the combination of environmental conditions before and during winter that selects on the host races. Many tests for trade-offs fail to adequately consider the interplay between insect development, host plant phenology, and local climatic conditions. Our findings suggest that such oversight may help to explain the paucity of reported fitness trade-offs.

The introduction of alien species can have a significant impact on the food preferences of native phytophagous insects. The moth Earias clorana L. has previously been considered to be monophagous, ingesting only plants in the genus Salix. In recent years, we have observed larval E. clorana feeding on Spiraea tomentosa L., an invasive shrub species in Central Europe that is native to North America. We hypothesised that this insect can feed on Spiraea tomentosa leaves with no negative effects on its growth and development, and that the leaves of Spiraea tomentosa as a source of food for E. clorana are equally as good as leaves of Salix viminalis L. Our results showed that despite significant differences in the chemical composition of the studied species' leaves, including a much higher concentration of defence compounds (total soluble phenols and condensed tannins) in Spiraea tomentosa leaves than in those of Salix viminalis, feeding on a new host plant did not significantly affect the survival of larvae. The change in host plant had an unfavourable effect, however, on several parameters of growth and development for the larvae (masses of larvae and pupae, relative growth rates, and efficiency of conversion of ingested food). We conclude that, in comparison to Salix viminalis, Spiraea tomentosa is not a particularly favourable food for larval development. Perhaps, even without direct improvements in adult foraging efficiency, however, the costs of switching hosts may be minimised in larvae that develop on very abundant, invasive species, such as Spiraea tomentosa in Central Europe.
