“…Increased herbivory could impose strong selection on plant populations for constitutive and inducible defenses . Future studies can evaluate evolutionary responses by quantifying genetic variation in defenses within and across populations in conjunction with estimating gene flow rates, comparing patterns of selection on defenses under historical, contemporary and future climates, and taking resurrection approaches to test directly for adaptive responses to climate change and increased herbivory (see Section IV on evolutionary responses) (Agrawal et al ., 2006; Franks et al ., 2018a).…”

“…Another promising technique is the resurrection approach of comparing ancestors and descendants under common conditions to directly examine evolutionary change (Franks et al ., 2018b). One study used ancestral and descendant seeds of B. rapa plants and showed that the evolutionary changes that occurred through artificial selection for rapid cycling resulted in changes to herbivore preference and performance (Franks et al ., 2018a). Resurrection studies may be more challenging to use for insects than plants, as seeds can often be stored long‐term.…”

“…However, in our study, Cynara scolymus had an oddly high oviposition PI value compared to other test species of similar phylogenetic distance. Being an agricultural plant, it is possible that artificial selection for desirable crop traits has also resulted in traits enhancing its palatability and acceptance to insect herbivores 64,65 …”

BACKGROUNDPredicting the host range of biocontrol agents is important for the safe and effective implementation of biocontrol of weeds. In this study, we examined the phylogenetic pattern of host selection and acceptance by the biocontrol beetle, Cassida rubiginosa. The beetle was released in New Zealand for control of Cirsium arvense, its primary host plant, but has potential to attack many Cardueae (thistles and knapweeds) species. We conducted a series of no‐choice and choice experiments and modelled the responses of Cassida rubiginosa in relation to phylogenetic distance from Cirsium arvense.RESULTSThe olfactory recognition (single odour) and preference (two odours) of the beetle showed a significant phylogenetic relationship. These relationships showed a high degree of correlation with 66.9% of the variation in olfactory recognition and 82.8% of the variation in olfactory preference explained by phylogeny. Where the beetle could contact plants, under no‐choice conditions there was no phylogenetic pattern to host plant acceptance. However, under choice conditions, phylogenetic distance was a strong predictor of feeding and oviposition preference. These relationships showed a high degree of correlation, with 63.4% of the variation in feeding preference, and 89.0% of the variation in oviposition preference, explained by phylogeny.CONCLUSIONSAs far as we are aware, this is the first demonstration of an herbivorous insect that exhibits a phylogenetic pattern to olfactory host plant selection. Host plant utilisation by Cassida rubiginosa in New Zealand will be mostly restricted to Cirsium and Carduus species, with minimal potential for impact on other Cardueae weeds. © 2023 The Authors.

“…Early applications of the resurrection approach revealed quantitative genetic differentiation between successional stages of arctic plants (McGraw, 1993) and adaptive evolution of zooplankton in response to environmental disturbances (Hairston et al, 1999). Recent resurrection studies have revealed contemporary evolution of phenology (Dickman et al, 2019; Franks et al, 2007; Nevo et al, 2012; Thomann et al, 2015), evolution of adaptive plasticity (Sultan et al, 2013) and responses to herbivory (Bustos‐Segura et al, 2014; Franks, Genovese, et al, 2018). Comparisons of antecedent and modern populations using population genetic techniques allow researchers to track changes in genetic diversity (Nevo et al, 2012) and quantify the molecular changes underlying trait evolution (Franks et al, 2016).…”

Resurrection experiments provide a unique opportunity to evaluate phenotypic and molecular evolution in response to environmental challenges. To understand the evolution of urban populations of Helianthus annuus, we compared plants from 36‐year‐old antecedent seed collections to modern seed collections from the same area using molecular and quantitative genetic approaches. We found 200 differentially expressed transcripts between antecedent and modern groups, and transcript expression was generally higher in modern samples as compared to antecedent samples. Admixture analysis indicated gene flow from domesticated to modern populations over time. After a greenhouse refresher generation, one antecedent–modern population pair was grown under two water availability (well‐watered and drought) and temperature (ambient and elevated by 2.8°C) conditions reflecting historical and contemporary climates. Overall, 78% (7 out of 9) of traits differed between the antecedent and modern populations, with modern individuals displaying some trait changes that are coherent with climate changes expectations and some trait changes in the direction of crop varieties. Phenotypic selection analysis showed that modern trait values were often favoured by selection, especially in environmental treatments resembling modern conditions. Trait heritability in the antecedent population was five times as high as in the modern population, on average. In addition, phenotypic plasticity for some traits, such as flowering phenology, was present in the antecedent population but absent in the modern population. The combination of phenotypic and molecular information suggests that evolution has been influenced by crop‐wild introgression, adaptive processes and drift. We discuss these results in the context of continued evolution in response to anthropogenic factors.
