“…Relatively simple plant genetic mechanisms can suffice to cause such geographic variations (e.g. Nielsen, 1996;Linhart & Thompson, 1999). For instance, the flea beetle Phyllotreta nemorum uses three species of Barbarea (Brassicaceae) as hosts in Denmark (Nielsen, 1996).…”

Only certain populations of the most common of the three plants, B. vulgaris, are used as hosts by the beetle since most B. vulgaris populations are toxic to P. nemorum.…”

“…However, some beetle populations live on B. vulgaris that are toxic to beetles from other sites. A small number of insect genes is responsible for this pattern of resistance and susceptibility (Nielsen, 1996). Thus, the fact that an allopatric plant is an accepted host under experimental conditions does not necessarily mean that it would be used by a sympatric insect population in nature.…”

Studies asking the ability of insects to utilize novel host plants often use novel hosts that are allopatric with the insect population under investigation. However, since the outcomes of species interactions are often site-specific, such studies cannot tell us whether a plant would actually be used by a given insect population if the plant grew sympatrically with it. We therefore performed a quantitative genetics experiment to analyse the performance of larvae of the leaf beetle Oreina elongata Suffrian (Coleoptera: Chrysomelidae, Chrysomelinae) on two host and three non-host plants, collected from a site where insects and plants co-occur in the Western Alps. When raised on the non-host Petasites albus (L.), larvae were able to survive equally well as on the two hosts, Adenostyles alliariae (Gouan) and Cirsium spinosissimum (L.), whereas they did not survive on the two other non-hosts, Peucedanum ostruthium (L.) and Rumex alpinus L. On P. albus, growth rate was slightly lower and development time slightly longer than on the two hosts. We found a genotype by environment interaction only for growth rate but not for development time and survival. However, the shape of the reaction norms of growth rates suggests that it is unlikely that selection could favour the inclusion of P. albus into the host range of the study population.

“…It is also suggested that B. vulgaris contains specific feeding deterrents or toxins to the flea beetle, P. nemorum, although the compounds have not yet been identified (Nielsen, 1996(Nielsen, , 1997a. The feeding of P. nemorum is also prevented by the cardenolides and cucurbitacins in Erysimum and Iberis (Nielsen, 1978).…”

Larvae of the diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), a crucifer specialist, refuse to feed on the wintercress, Barbarea vulgaris R. Br. (Brassicaceae). The mechanism of this unacceptability to P. xylostella was evaluated by a series of no-choice bioassays using leaf disks. Topical application of sinigrin enhanced feeding of the larvae on the leaf disks of a non-host plant, lettuce (Lactuca sativa L.), but not on those of B. vulgaris. Application of the crude methanolic extract from B. vulgaris leaves deterred P. xylostella feeding on the leaf disks of cabbage (Brassica oleracea L.) in a dose-dependent manner. This feeding deterrent activity was transferred predominantly to the chloroform fraction, but not to the n-hexane or water fractions. These results suggest that the unacceptability of B. vulgaris to P. xylostella larvae is mainly due to chemical constituent(s) extractable with chloroform.

“…No linkage was found in other herbivorous species, such as Callosobruchus maculatus (southern cowpea weevil; Wasserman and Futuyma 1981), Colias philodice (butterfly; Tabashnik 1986), Papilionidae (swallowtail butterflies; Thompson 1988;Thompson et al 1990), Chrysomelidae (leaf-feeding beetles; Keese 1996), Nilaparvata lugens (brown planthopper; Sezer and Butlin 1998a,b), and Oreina elongata (leaf beetle; Ballabeni and Rahier 2000). However, more recent QTL mapping data for aphids (Hawthorne and Via 2001;Caillaud and Via 2012;Sauge et al 2012), and other genetic association studies in Euphydryas editha (Edith's checkerspot butterfly ;Ng 1988;Singer et al 1988), Liriomyza sativae (leafminer fly; Via 1986), Phyllotreta nemorum (flea beetle; Nielsen 1996), and Papilio glaucus (eastern tiger swallowtail butterfly; Bossart 2003), suggest that some preference and performance alleles can be genetically linked.…”

A Locus in Drosophila sechellia Affecting Tolerance of a Host Plant Toxin

et al. 2013

Many insects feed on only one or a few types of host. These host specialists often evolve a preference for chemical cues emanating from their host and develop mechanisms for circumventing their host's defenses. Adaptations like these are central to evolutionary biology, yet our understanding of their genetics remains incomplete. Drosophila sechellia, an emerging model for the genetics of host specialization, is an island endemic that has adapted to chemical toxins present in the fruit of its host plant, Morinda citrifolia. Its sibling species, D. simulans, and many other Drosophila species do not tolerate these toxins and avoid the fruit. Earlier work found a region with a strong effect on tolerance to the major toxin, octanoic acid, on chromosome arm 3R. Using a novel assay, we narrowed this region to a small span near the centromere containing 18 genes, including three odorant binding proteins. It has been hypothesized that the evolution of host specialization is facilitated by genetic linkage between alleles contributing to host preference and alleles contributing to host usage, such as tolerance to secondary compounds. We tested this hypothesis by measuring the effect of this tolerance locus on host preference behavior. Our data were inconsistent with the linkage hypothesis, as flies bearing this tolerance region showed no increase in preference for media containing M. citrifolia toxins, which D. sechellia prefers. Thus, in contrast to some models for host preference, preference and tolerance are not tightly linked at this locus nor is increased tolerance per se sufficient to change preference. Our data are consistent with the previously proposed model that the evolution of D. sechellia as a M. citrifolia specialist occurred through a stepwise loss of aversion and gain of tolerance to M. citrifolia's toxins. HALF of all insects interact with plants (Grimaldi and Engel 2005). Most phytophageous insects, however, use only a few plant genera for food, mating, and oviposition (Bernays and Chapman 1994). Changes in host use can result in both new species and new adaptations (Ehrlich and Raven 1964;Janz 2011). For example, the evolution of a new host specialization may have contributed to the formation of new species in pea aphids (Acyrthosiphon) among others (Via 2001;Matsubayashi et al. 2010). Adapting to a new host can drive genetic and phenotypic change that is critical for isolating nascent species. In some cases, specialization has a price: Increased performance on the new host correlates with reduced performance on other hosts (Futuyma and Moreno 1988;Jaenike 1990;Fry et al. 1996;Scheirs et al. 2005; Via and Hawthorne 2005). This scenario poses a new challenge for the nascent specialist, as it must keep together alleles for finding and selecting the appropriate host ("preference") along with those for utilizing that host ("performance," e.g., physiologically adapting to that host's secondary compounds or nutritional content; Jaenike 1990; Janz 2011). Theory suggests that a genetic correlation betwe...
