“…D. buzzatii was more affected by the artificial host shifts than D. koepferae . The former is depicted as a generalist exploiting columnar cacti (as T. terscheckii ), prickly pears (species of Opuntia genus), and even commercial fruits (Manfrin & Sene, 2006; Fanara et al ., 2016). In this sense, D. buzzatii successfully exploits T. terscheckii , the species present in the natural population of origin of the strains but failed to show the same successful pattern in other columnars.…”

“…They concentrate most of the current understanding of the pattern of host‐plant use in the cluster (Soto et al ., 2008, 2014; De Panis et al ., 2016; Markow, 2019). D. buzzatii primarily uses prickly pears (genus Opuntia ) as hosts but can also be found exploiting several genera of cactus and even commercial fruits (Manfrin & Sene, 2006; Fanara et al ., 2016). Its original distribution included northern Argentina, Bolivia, Paraguay, and Brazil but it has colonised Europe, Australia, and Africa in the last centuries due to unintentional human introduction (Barker, 2013).…”

1. We assessed the host-related niche breadth for D. koepferae and D. buzzatii, a pair of sibling cactophilic species with contrasting backgrounds of host use. We tested for the 'Jack of all trades-Master of none' scenario predicting a more evident exhibition in D. buzzatii rather than in the supposedly specialist D. koepferae.2. Additionally, using laboratory strains of both species selected for tolerance to extremely high concentrations of a columnar cacti's secondary metabolites, we tested whether adaptation to a high-demanding host involved the loss of performance capabilities in other hosts.3. D. buzzatii was more affected by the artificial host shifts than D. koepferae which presented an overall better performance when rearing in novel columnar hosts.4. Artificially selected strains of D. buzzatii performed poorer in both novel and native natural hosts compared with control strain indicating that adaptation carried associated costs regarding the potential to exploit other cacti. Conversely, artificial evolution of the D. koepferae's strains did not translate into decreased performance in other hosts.5. D. buzzatii complied better with the predictions of the Jack of all trades-Master of none hypothesis.6. Host specialization is a dynamic feature in the repleta group and a major driver of diversification in its evolutionary history. As the group presents an Opuntia breeder as the ancestral condition, D. buzzatii would represent not only a plesiomorphic state of host use but also the ancestral ecological strategy of specialization.

“…The different responses might also be interpreted in the context of ecological specialization of these catophilic flies. Based on previous results (Bouzas et al, 2021), D. buzzatii may be considered a successful generalist exploiting T. terscheckii , Opuntia species, and even commercial fruits (Manfrin & Sene, 2006; Fanara et al, 2016). Unlike fruits and prickly pears, columnar cacti present a wide and complex array of chemical defenses (Trout, 2014) and this might be responsible for the decreased viability and increased DT observed in the C and H strains of this species.…”

“…Such sub-cosmopolitan distribution is the result of its association with prickly pears of the genus Opuntia , which themselves spread by human intervention and became established [ 27 ]. It has been recently reported, however, the first record of D. buzzatii emerging from a non-cactus host in western Argentina [ 28 ]. Moreover, in recent field collections, we found that D. buzzatii can emerge from rotting grapes ( Vitis vinifera ), asserting the capacity of this species to exploit other nutritional resources than cacti (E.M.S., E.H. and J.M., unpublished results [ 29 ]).…”

Under the preference-performance hypothesis, natural selection will favor females that choose oviposition sites that optimize the fitness of their offspring. Such a preference-performance relationship may entail important consequences mainly on fitness-related traits. We used the well-characterized cactus-Drosophila system to investigate the reproductive capacity in the pair of sibling species D. buzzatii and D. koepferae reared in two alternative host plants. According to our hypothesis, ovariole number (as a proxy of reproductive capacity) depends on host plant selection. Our results indicate that the capacity of D. buzzatii showed to be mild, only increasing the number of ovarioles by as much as 10% when reared in its preferred host. In contrast, D. koepferae exhibited a similar reproductive capacity across host cacti, even though it showed a preference for its primary host cactus. Our study also revealed that D. buzzatii has a larger genetic variation for phenotypic plasticity than its sibling, although ovariole number did not show clear-cut differences between species. We will discuss the weak preference-performance pattern observed in these cactophilic species in the light of nutritional and toxicological differences found between the natural host plants.
