“…The observation that different mtDNA haplotypes carry the same or very closely-related Wolbachia strains strongly indicates horizontal transmissions of Wolbachia between SBPH individuals. A similar phenomenon has also been reported in the fire ant Solenopsis invicta 31 and the fruit fly Drosophila willistoni 32 . The horizontal transmissions of Wolbachia make the natural infection status unstable in SBPH populations, and also interrupt the host speciation process induced by CI.…”

Understanding dispersal ability in pest species is critical for both theoretical aspects of evolutionary and population biology and from a practical standpoint, such as implementing effective forecasting systems. The small brown planthopper (SBPH), Laodelphax striatellus (Fallén), is an economically important pest, but few data exist on its dispersal ability. Here, we used mitochondrial and nuclear markers to elucidate the population genetic structure of SBPH and of the parasitic bacterium Wolbachia throughout temperate and subtropical China. Our results showed that the SBPH populations in China lack significant differences in genetic structure, suggesting extensive gene flow. Multilocus sequence typing revealed that Wolbachia infection was systematic and due to the same strain (wStri) within and across populations. However, the mtDNA haplogroups had a nonrandom distribution across the sampling localities, which correlated to latitudinal and climatic gradients. We explain this mito-nuclear discordance as a result of historical population recolonization or mitochondria adaptation to climate.

“…The identity of the different strains sequenced is abbreviated as in Figure 1 . Drosophila strains sequenced but not phenotypically assayed are identified as follows: Brazil (B 1 to B 15 = haplotypes 1 to 15); 38 Nicaragua (N 00 ); El Salvador (ES 01 ); Florida (F 02 ); México (M 03 , M 15 , M 28 , M 31 ); Guadeloupe (G 20 , G 25 ); Guana (GU 21 , GU 26 , GU 27 ); Uruguay (U 17 ). The names of the strains sharing the most common haplotype are boxed.…”

“…In addition, we incorporated mtCOI sequenced data available from Brazilian populations of D. willistoni (Accession numbers: JN705920 to JN705934). 38 Sequence data was aligned using MUSCLE within MEGA and the alignments used to calculate genetic distances and differentiation between strains. 39,40 The phylogenetic relationships among different haploid genotypes was reconstructed by using the method of Templeton, Candrall and Sing (TCS) to build a network of interconnected haplotypes.…”

Speciation can occur through the presence of reproductive isolation barriers that impede mating, restrict cross-fertilization, or render inviable/sterile hybrid progeny. The D. willistoni subgroup is ideally suited for studies of speciation, with examples of both allopatry and sympatry, a range of isolation barriers, and the availability of one species complete genome sequence to facilitate genetic studies of divergence. D. w. willistoni has the largest geographic distribution among members of the Drosophila willistoni subgroup, spanning from Argentina to the southern United States, including the Caribbean islands. A subspecies of D. w. willistoni, D. w. quechua, is geographically separated by the Andes mountain range and has evolved unidirectional sterility, in that only male offspring of D. w. quechua females × D. w. willistoni males are sterile. Whether D. w. willistoni flies residing east of the Andes belong to one or more D. willistoni subspecies remains unresolved. Here we perform fecundity assays and show that F1 hybrid males produced from crosses between different strains found in Central America, North America, and northern Caribbean islands are reproductively isolated from South American and southern Caribbean island strains as a result of unidirectional hybrid male sterility. Our results show the existence of a reproductive isolation barrier between the northern and southern strains and suggest a subdivision of the previously identified D. willistoni willistoni species into 2 new subspecies.

“…sturtevanti populations are naturally infected with Wolbachia (Miller & Riegler, 2006), however, we still have to investigate the association between the mitochondrial and Wolbachia haplotypes, to understand if it is interfering in the observed variation. Müller et al (2012) showed no evidence that Wolbachia infections could be decreasing the diversity of mtDNA in D. willistoni natural populations, even with and infection rate as high as 55%.…”

Pleistocene climatic changes have played a major role on the evolution Brazilian Atlantic Forest and South America biodiversity but their impacts on the genetic structure of widely distributed species remain unclear. Here, we investigate mitochondrial DNA (mtDNA) diversity in 21 geographical populations of Drosophila sturtevanti, Nucleotide sequences of the cytochrome C oxidase subunits I and II genes (COI and COII, respectively) from 163 individuals, showed a significant northsouth structure, in spite of an overall low level of variation. The haplotypes clustered in three groups that showed strong correlations with geographical and climatic variables, suggesting that local adaptations might have contributed to differentiation within the species. Coalescent-based analyses indicated that the three clusters have differentiated nearly ~17.000 years ago, suggesting a major role for Pleistocene changes in shaping current day distributions and differentiation of widespread Neotropical species.
