“…This concept, which is the central idea of the ‘preference‐performance’ or the ‘mother knows best’ hypothesis, has been highly debated and empirical evidence has been provided in favor (Jaenike, 1978; Johnson et al., 2006; Gripenberg et al., 2010) and against (Berdegue et al., 1998; Mayhew, 2001; Clark et al., 2011). It has been shown that constitutive and induced plant resistance traits negatively affect herbivore preference and performance (Kessler & Baldwin, 2002; Wise & Weinberg, 2002; Lamb et al., 2003) but to our knowledge there are just two empirical studies investigating how tolerance traits can affect herbivore performance (Espinosa & Fornoni, 2006; Utsumi et al., 2011). Espinosa & Fornoni (2006) showed that different genotypes of Datura stramonium L., with varying degrees of tolerance, did not affect the development of the chrysomelid beetle Lema trilineata Olivier, suggesting that host tolerance could relax the selective pressure on herbivores.…”

Overcompensation is a plant tolerance response in which plants have higher fitness after herbivory than without damage. Although it has been demonstrated that plants are able to simultaneously express resistance and tolerance traits, it remains unclear whether overcompensating plants are also inducing resistance-mediating secondary metabolite production and how herbivores perform on plants that overcompensate. Our previous work has shown that a potato variety [Solanum tuberosum L. cv. Pastusa Suprema (Solanaceae)] from Colombia can express overcompensatory responses to damage by larvae of the Guatemalan potato moth, Tecia solanivora Povolny (Lepidoptera: Gelechiidae). Here we investigated (1) whether potatoes that express overcompensatory responses also induce resistance traits and (2) how the previous damage affects Guatemalan potato moth preference and performance. Our results show that larval feeding not only systemically induces higher tuber biomass but also an increased production of resistance-related compounds, such as phenolics and proteinase inhibitors. Pupal mass increased with increasing tuber size, whereas changes in tuber secondary metabolism did not correlate with any metric of larval performance. Oviposition preference did not change between induced and undamaged plants. Our data show that potato plants expressing overcompensatory responses also induce secondary compounds known to increase resistance against herbivores. However, the induced response was relatively small, reducing the opportunities for a negative effect on the herbivore. Hypotheses for why larvae perform better in larger tubers and are not affected by the secondary metabolism are discussed. From an ecological and agricultural point of view, our results suggest that the expression of overcompensatory traits could have positive effects on herbivore performance

“…It was reported that wheat midge infestation was associated with a reduced proportion of well-formed wheat seeds and yield losses (Glen 2000;Lamb et al 2003;Doane and Olfert 2008). Therefore, alternative control methods are required to manage wheat midge's species such as monitoring tools, cultural control, agronomic practices, chemical control, biological control and plant resistance (Olfert et al 2009); the important one of these alternative strategies is resistant varieties.…”

Assessment of wheat ear insects in winter wheat varieties in central Germany

Population densities of wheat ear insects infesting different winter wheat varieties (n = 50) were estimated during 2008 and 2009 seasons near Halle, central Germany. The research was aimed at identifying wheat varieties most resistant to wheat ear insect pests. Two methods were used to evaluate the degree of insect infestations in different wheat ear varieties. Wheat ears were dissected when kernels were in Zadoks stage 73 and examined using a binocular microscope to count the number of spikelets and infested kernels, and to identify the insect pests present. In addition, white water traps were placed on the soil underneath each variety to collect mature larvae of wheat blossom midges (WBMs) as an indicator of potential crop risk for the next year. There were significant differences in the number of thrips and WBM infesting wheat ears among varieties in both years. Thrips numbers were the highest in Akratos, Limes and Ritmo varieties in 2008 and in Michigan Amber, Elegant and Kontrast in 2009. Thrips were the lowest in Thuareg in 2008 and Robigus varieties in 2009. The results showed that the highest WBM infestation level was observed in Michigan Amber in both years. The lowest WBM infestations were found in Türkis, Cubus, Capo, Welford and Robigus in both years. The number of infested kernels was positively correlated with WBM among varieties. In the water traps, the highest numbers of WBM larvae were recorded in Saladin and Bussard in 2008 and Orlando, Julius and Glasgow varieties in 2009. The lowest values were recorded in Victo, Enorm, Robigus and Welford varieties in both years. The results provide a guide for selecting winter wheat varieties with resistance to these wheat ear pests.

“…Analogous logic predicts that selection may act epistatically on antixenosis and antibiosis such that these two components of resistance would become negatively genetically correlated. So far, much more theoretical and empirical eVort has been devoted to resistance-tolerance correlations, though antixenosis-antibiosis correlations have just as much relevance to the evolutionary ecology of plant defense (TiYn 2000;Lamb et al 2003).…”

Good mothers, bad mothers, and the nature of resistance to herbivory in Solidago altissima

et al. 2007

Evidence of poor correspondence between an insect herbivore's oviposition preferences and the performance of its offspring has generally been attributed either to maladaptive behavior of the insect mother or inadequate measurement by the researcher. In contrast, we hypothesize that many cases of "bad mothers" in herbivores may be a byproduct of the hierarchical way natural selection works on resistance in host plants. Epistatic selection on the components of resistance (i.e., antixenosis and antibiosis) may generate negative genetic correlations between the resistance components, which could counteract the efforts of herbivores to oviposit on the best hosts for the performance of their offspring. In common garden and greenhouse experiments, we measured aspects of antixenosis and antibiosis resistance in 26 genets of tall goldenrod, Solidago altissima, against two common herbivores: the gall-inducing fly Eurosta solidaginis and the spittlebug Philaenus spumarius. Goldenrod antixenosis and antibiosis were positively correlated against E. solidaginis and negatively correlated against P. spumarius. Analogously, population-wide preference-performance correlations were positive for the gall flies and negative for the spittlebugs. Several natural history differences between the two insects could make gall flies better mothers, including better synchrony of the phenologies of the flies and the host plant, the much narrower host range of the gall flies than the spittlebugs, and the more sedentary lifestyle of the gall fly larvae than the spittlebug nymphs. If these results are typical in nature, then negative genetic correlations in antixenosis and antibiosis in plants may often result in zero or negative population-wide correlations between preference and performance in herbivores, and thus may be an important reason why herbivorous insects often appear to be bad mothers.
