“…In contrast, shifting the scramble‐competing population (BF) to a smaller host did not lead to changes in larval competitiveness or egg size, but the lines did evolve larger adult mass. These asymmetric responses to host shifts are similar to those previously observed for oviposition behaviour (Fox et al ., ): SI lines switched to the larger host evolved reduced avoidance of seeds bearing previously laid eggs, but BF lines switched to a smaller host did not evolve greater avoidance of egg‐laden seeds.…”

Resource competition is frequently strong among parasites that feed within small discrete resource patches, such as seeds or fruits. The properties of a host can influence the behavioural, morphological and life-history traits of associated parasites, including traits that mediate competition within the host. For seed parasites, host size may be an especially important determinant of competitive ability. Using the seed beetle, Callosobruchus maculatus, we performed replicated, reciprocal host shifts to examine the role of seed size in determining larval competitiveness and associated traits. Populations ancestrally associated with either a small host (mung bean) or a large one (cowpea) were switched to each other's host for 36 generations. Compared to control lines (those remaining on the ancestral host), lines switched from the small host to the large host evolved greater tolerance of co-occurring larvae within seeds (indicated by an increase in the frequency of small seeds yielding two adults), smaller egg size and higher fecundity. Each change occurred in the direction predicted by the traits of populations already adapted to cowpea. However, we did not observe the expected decline in adult mass following the shift to the larger host. Moreover, lines switched from the large host (cowpea) to the small host (mung bean) did not evolve the predicted increase in larval competitiveness or egg size, but did exhibit the predicted increase in body mass. Our results thus provide mixed support for the hypothesis that host size determines the evolution of competition-related traits of seed beetles. Evolutionary responses to the two host shifts were consistent among replicate lines, but the evolution of larval competition was asymmetric, with larval competitiveness evolving as predicted in one direction of host shift, but not the reverse. Nevertheless, our results indicate that switching hosts is sufficient to produce repeatable and rapid changes in the competition strategy and fitness-related traits of insect populations.

“…Rdl dieldrin resistance in Drosophila melanogaster , ffrench‐Constant et al 2000), converse cross‐resistance may thus have significant ecological consequences for the agroecosystems through altered host plant ranges in both pests and non‐target species (Figure 3). Adaptation to a novel host plant may affect various biological traits (Box 3), making the evolutionary outcome unpredictable (Fox et al, 2017). Such trait evolution may further lead to both direct and indirect eco‐evolutionary effects up to the species community scale (Utsumi, 2011).…”

Pesticide resistance in arthropods: Ecology matters too

Pesticide resistance development is an example of rapid contemporary evolution that poses immense challenges for agriculture. It typically evolves due to the strong directional selection that pesticide treatments exert on herbivorous arthropods. However, recent research suggests that some species are more prone to evolve pesticide resistance than others due to their evolutionary history and standing genetic variation. Generalist species might develop pesticide resistance especially rapidly due to pre‐adaptation to handle a wide array of plant allelochemicals. Moreover, research has shown that adaptation to novel host plants could lead to increased pesticide resistance. Exploring such cross‐resistance between host plant range evolution and pesticide resistance development from an ecological perspective is needed to understand its causes and consequences better. Much research has, however, been devoted to the molecular mechanisms underlying pesticide resistance while both the ecological contexts that could facilitate resistance evolution and the ecological consequences of cross‐resistance have been under‐studied. Here, we take an eco‐evolutionary approach and discuss circumstances that may facilitate cross‐resistance in arthropods and the consequences cross‐resistance may have for plant–arthropod interactions in both target and non‐target species and species interactions. Furthermore, we suggest future research avenues and practical implications of an increased ecological understanding of pesticide resistance evolution.

“…This phenomenon has been well studied in the laboratory model species and invasive stored product pest Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae). In particular, rapid adaptation in C. maculatus by placement in environments containing hosts of marginal quality has been well documented (Fox, Stillwell, Amarillo‐S, Czesak, & Messina, ; Fox, Wagner, Cline, Thomas, & Messina, ; Fox, Zitomer, Deas, & Messina, ; Messina, ; Messina & Gompert, ). Furthermore, evolutionary rescue in C. macualtus in response to populations being experimentally shifted to a marginal quality host, Lens culinaris, was determined to have been caused by strong selection on a small number of loci (Rêgo, Messina, & Gompert, ).…”

Local adaptation can lead to significant differences in host use that may influence population growth and spread. Here, we test the potential for adaptation of one behavioural component (host acceptance) to lead to cross‐adaptation for a separate behavioural component (dispersal propensity) using the cowpea seed beetle, Callosobruchus maculatus. C. maculatus originating from the same source population were subjected to selection for host use by rearing them for over 40 generations on either the preferred host of the ancestral population, Vigna radiata, or a marginal host for the ancestral population, Cicer arietinum. Host acceptance was then assayed using four choice and no‐choice oviposition assays including a low‐quality host, Lens culinaris, a marginal host, C. arietinum, and two high‐quality hosts, V. radiata and V. unguiculata. Dispersal was assayed in interconnected arenas containing one of three different hosts: V. radiata, V. unguiculata or C. arietinum. As expected, differences in host acceptance were present, in this case consisting of greater acceptance of the lower quality hosts in the C. arietinum population, but no significant differences in host preference hierarchy. Dispersal propensity in the C. arietinum population was significantly lower than in the V. radiata population, despite the absence of any difference in selection pressures for dispersal. Furthermore, significant differences in dispersal propensity in arenas containing different hosts were present in the V. radiata population, but not in the C. arietinum population. Results highlight the need to consider local adaptation when developing management recommendations, even for behaviours for which selection pressures are not directly apparent.
