“…Even though these studies have used data from a range of methods, including behavior, morphometrics, karyotype, isozymes, pheromone, cuticular hydrocarbons, mtDNA and reproductive studies, they lack a comprehensive sampling across the species’ range and fail to fully integrate molecular and phenotypic data, which complicates their use in species identification. An indication of the complex taxonomic questions in this genus is that single-gene molecular phylogenies based on mtDNA ( McPheron et al, 1999 ; Smith-Caldas et al, 2001 ) or nuclear genes ( Barr et al, 2005 ; Ruiz et al, 2007 ; Sarno et al, 2010 ; Gonçalves et al, 2013 ), and even using multiple genes ( Mengual et al, 2017 ) have failed to identify species-specific fixed differences among the most closely related taxa, leading some to propose a multidisciplinary approach ( Dias et al, 2016 ).…”

Evidence for Introgression Among Three Species of the Anastrepha fraterculus Group, a Radiating Species Complex of Fruit Flies

et al. 2018

Introgression should no longer be considered as rare a phenomenon as once thought, since several studies have recently documented gene flow between closely related and radiating species. Here, we investigated evolutionary relationships among three closely related species of fruit flies of the Anastrepha fraterculus group (Anastrepha fraterculus, A. obliqua and A. sororcula). We sequenced a set of 20 genes and implemented a combined populational and phylogenetic inference with a model selection approach by an ABC framework in order to elucidate the demographic history of these species. The phylogenetic histories inferred from most genes showed a great deal of discordance and substantial shared polymorphic variation. The analysis of several population and speciation models reveal that this shared variation is better explained by introgression rather than convergence by parallel mutation or incomplete lineage sorting. Our results consistently showed these species evolving under an isolation with migration model experiencing a continuous and asymmetrical pattern of gene flow involving all species pairs, even though still showed a more closely related relationship between A. fraterculus and A. sororcula when compared with A. obliqua. This suggests that these species have been exchanging genes since they split from their common ancestor ∼2.6 MYA ago. We also found strong evidence for recent population expansion that appears to be consequence of anthropic activities affecting host crops of fruit flies. These findings point that the introgression here found may have been driven by genetic drift and not necessary by selection, which has implications for tracking and managing fruit flies.

The Panel on Plant Health performed a group pest categorisation of non-EU Tephritidae, a large insect family containing well-studied and economically important fruit fly species and little studied species with scarce information regarding their hosts and species that do not feed on plants. Information was saught on the distribution of each species and their hosts. Tephritidae occur in all biogeographic regions except in extreme desert and polar areas, where their hosts are scarce or absent. Non-European Tephritidae are listed in 2000/29 EC as Annex 1/A1 pests whose introduction into the EU is prohibited. Non-EU Tephritidae are regularly intercepted in the EU. Interceptions mainly occur on fruits although there is potential for entry on other plant parts. Beginning with over 5,000 recognised species, factors relevant for pest categorisation were sequentially used to narrow down the list of species to create a list of Tephritidae not known to be established in the EU yet which occur in countries with some EU climate types and which feed on plants that occur in the EU. Following the introduction of pest species, impacts on cultivated host plants could result in yield and quality losses; harmful impacts on wild hosts are uncertain. Phytosanitary measures are available to prevent the entry of non-EU Tephritidae. Results are presented in a series of appendices listing species screened during the process. Of 4,765 species regarded as non-EU Tephritidae, 257 species satisfy the criteria assessed by EFSA such that they can be considered as potential quarantine pests for the EU. Lack of information of the distribution of hosts and/or impact on wild hosts means 1,087 species of non-EU Tephritidae do not satisfy all criteria to be considered as potential quarantine pests for the EU. Non-EU Tephritidae do not meet the criteria assessed by EFSA for consideration as regulated non-quarantine pests, as members of the group are not present in the EU and plants for planting are not the main means of spread.

The first records of six Anastrepha species are reported for the state of Paraná, Brazil, namely A. amita Zucchi, 1979; A. barnesi Aldrich, 1925; A. consobrina (Loew, 1873); A. manihoti Lima, 1934; A. morvasi Uramoto & Zucchi, 1999; and A. punctata Hendel, 1914. Citharexylum solanaceum Cham. (Verbenaceae) is recorded as a new host plant for A. amita, and Inga vera Willd. (Fabaceae) as new host plant for A. distincta. With these new records the number of species of Anastrepha recorded from Paraná is increased from 15 to 21.
