“…We hypothesise that the lack of strong temperature preference in D. melanogaster may have contributed to this species' ability to successfully inhabit the globe. An interesting contrast, however, is the agricultural pest, D. suzukii, which is currently undergoing a global expansion 54,79,80 but has a relatively strong cool preference (Epeak: 17.4˚C; Epeak median: 0.149), consistent with previous reports in adults 81,82 . This D. suzukii example implies that a weak temperature preference does not necessarily precede a poikilotherm's global spread.…”

Small-bodied ectotherms are acutely vulnerable to temperature changes but diverse thermotactic behaviours have contributed to their ability to inhabit broad climatic niches. Understanding how - and how fast - these behaviours evolve are outstanding biological questions that are also relevant to conservation. Among insects,Drosophila melanogasteris a preeminent ectothermic model for temperate sensing and thermotaxis. However, little is known about how its temperature-related behaviours have evolved in comparison to its closely-related species. We have thermo-profiled over ~2400 larvae from eight closely related species ofDrosophilafrom different thermal habitats. We found substantial variation in temperature preference and fine-scale navigational behaviours amongst these species, consistent with local adaptation. Agent-based modelling of the larval thermotaxis circuit indicate that it is the balance between cool and warm avoidance circuits, rather than changes in temperature sensitivity, that drive differences in temperature preference. Together, our findings highlight the fast evolution of temperature-related behaviours in an experimentally tractable cross-species system.

“…Another striking clade is C10, which comprises only identical wsp sequences that are equally distributed in America, Australia, Asia, and some in Europe, and the most likely ancestral node is Australia, suggesting that this clade emerged from Australia and spread to the other continents. This clade contains invasive species and agricultural pests, Bactrocera frauenfeldi, that spread from Papua New Guinea to Australia, and Drosophila suzukii, that spread within a few years from Western Asia to Europe, North and South America [32][33][34]. The fact that some members of this clade occur in host species with invasive capabilities could explain the spread of identical strains between different continents.…”

Background Wolbachia are highly prevalent endosymbiotic bacteria infecting more than two-thirds of arthropods. While Wolbachia are mainly transmitted vertically through the female germline, experiments and phylogenetic studies have suggested that horizontal transmission between hosts is not uncommon. In this study, we aim to get a better understanding of horizontal transfer events between hosts of different orders and between continents using a large database containing nucleotide sequences of the genes wsp and ftsZ. Results Our results show a high frequency of horizontal Wolbachia transmission between host orders and continents, but nevertheless detectable signals of the host phylogeny and geography in the Wolbachia phylogeny. Two different approaches for estimating transition rates between host orders from phylogenies produced evidence that Wolbachia transition rates between some insect orders are unidirectional. Furthermore, the phylogenies and transition rate estimates differed between the genes, suggesting that not all genes are equally likely to spread in a new host following horizontal transmission. This discrepancy between genes, however, is more evident on a larger timescale because highly similar sequences were grouped in the same clades on both genes. Conclusions Together, these results contribute to understanding the dynamics and patterns of Wolbachia host shifts and generate new hypotheses about factors that might prevent horizontal Wolbachia transfer. These insights have important implications for controlling disease vectors or understanding the coevolution of hosts and their associated microbes.
