“…Then, the program was run using the L mode for additional steps specifying details for the IM model and number of parameters to estimate. Because all parameters estimated by IMa2 are scaled by mutation rates, we estimated the mutation rate per year for each locus based on the split time reported for Tephritidae (∼36 million years) ( Beverley and Wilson, 1984 ; Norrbom, 1994 ; Han and Ro, 2016 ) and a generation time of 0.11 years for Anastrepha ( Celedonio-Hurtado et al, 1988 ; Joachim-Bravo et al, 2003 ) in order to convert the estimated parameters into demographic scales.…”

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

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.

“…At this point, longevity and fertility of old ßies becomes an important character in surviving this dearth of hosts and continuing the species. Joachim-Bravo et al (2003) studied the longevity and fertility over time of four species of Anastrepha occurring in Brazil, including A. obliqua. They found that longevity differed by species, with 50% of Anastrepha fraterculus (Weidemann) females surviving to 115 d (maximum of 190 d), and 50% of A. obliqua females surviving to 80 d (maximum of 160 d) and that these two species had lower longevity than the other two species studied (Anastrepha zenildae Zucchi and Anastrepha sororcula Zucchi).…”

McPhail-type traps baited with ammonium acetate and putrescine were used to monitor populations of Anastrepha obliqua (Macquart) and Anastrepha suspensa (Loew) in two orchards with hosts of these flies (mango, Mangifera indica L., and carambola, Averrhoa carambola L.), as well as in forest fragments bordering these orchards. Contour maps were constructed to measure population distributions in and around orchards. Our results indicate that Anastrepha populations are focused around host fruit in both space and time, that traps do not draw fruit flies away from hosts, even when placed within 15 m of the host, and that lures continue to function for 6 mo in the field. The contour mapping analyses reveal that populations of fruit flies are focused around ovipositional hosts. Although the trapping system does not have a very long effective sampling range, it is ideal, when used in combination with contour analyses, for assessing fine-scale (on the order of meters) population distributions, including identifying resources around which fly populations are focused or, conversely, assessing the effectiveness of management tools. The results are discussed as they pertain to monitoring and detecting Anastrepha spp. with the McPhail-type trap and ammonium acetate and putrescine baiting system and the dispersal of these flies within Puerto Rico.

“…To date, a large amount of information has been accumulated regarding the life‐history evolution of the multivoltine, polyphagous species of Tephritidae (Carey, 1984, 2011; Carey, Harris & McInnis, 1985; Papadopoulos, Katsoyannos & Carey, 2002; Joachim‐Bravo et al ., 2003; Diamantidis et al ., 2009; Duyck et al ., 2010). However, little is known about the demography of multivoltine oligophagous species (Brèvault, Duyck & Quilici, 2008) and, particularly, univoltine stenophagous species (Wiesmann, 1933; Leski, 1963; Boller, 1966a; Boller & Prokopy, 1976; Kasana & AliNiazee, 1994).…”

To understand the evolution of local adaptation, the interplay between natural selection and gene flow should be considered. Rhagoletis cerasi L. (Diptera: Tephritidae) is a patchily distributed, stenophagous species of the temperate zone, and the geographical structure of its populations reveals substantial variation in gene flow rates across its distribution range. We studied the demographic components of R. cerasi adults from Greek and German populations by estimating the variability in fitness traits among allopatric populations, as well as among geographically discrete populations, with gene flow. Assuming that body size may exert a profound effect on adult fitness, both thorax and head sizes were considered as covariates in our analyses. Our data demonstrated that females were larger than males in all populations, and adult size varied significantly among populations within groups. Significant differences in a suite of life-history traits of R. cerasi adults were detected among populations with gene flow, whereas there were no consistent differences among allopatric populations. Therefore, the genetic differences among R. cerasi populations, driven mainly by geographical isolation, are poor predictors of variation in the life-history traits of adults.
