“…These patterns suggest the existence of one or several Wolbachia strains harboured by different A. obliqua populations. Similar post‐zygotic isolation patterns have been found between cryptic species in the A. fraterculus complex (Devescovi et al., ), which harbour different strains of Wolbachia (Prezotto, Perondini, Hernández‐Ortiz, Marino, & Selivon, ; Selivon et al., , ). Exploring the existence of the bacteria and characterizing its different strains among A. obliqua populations are important since it could facilitate colonization, strain refreshment, efficient mass rearing for application of the SIT, and eventually lead to the development of the incompatible insect technique (IIT) (Zhang, Lees, Xi, Bourtzis, & Gilles, ).…”

The fraterculus species group, composed of 34 species in the genus Anastrepha (Diptera: Tephritidae), includes the fraterculus cryptic species complex formed by eight reproductively isolated morphotypes. A previous study revealed six genetic mitochondrial types of Anastrepha obliqua, suggesting the existence of a second cryptic species complex. However, marked discrepancies between nuclear and mitochondrial loci rather suggest incomplete lineage sorting or introgression between A. obliqua and A. fraterculus. Such hybridization could nevertheless result in reproductive isolation, an outcome that could affect efficacy of area‐wide management for the most important pest of mangos in America. Two mitochondrial types occur in Mexico, and the limits of a third one, encompassing Central American populations, have not been clearly established. Here, we tested reproductive compatibility among three A. obliqua populations from the Pacific and a population from the Gulf of Mexico. No evidence of pre‐zygotic isolation was found. Flies from the Atlantic mated randomly for equal duration with individuals from three Pacific populations. Homotypic and heterotypic crosses produced similar numbers of eggs, with heterotypic crosses of Pacific males and Atlantic females hatching in lower proportions. Larvae of all cross types developed equally in mangos and exhibited no sex ratio distortion of hybrid F1. The three mitochondrial types identified in Mexico and Central America do not appear to be cryptic species and can be managed using one single strain for the sterile insect technique.

“…In this work, some degree of postzygotic reproductive isolation was found among F1 crosses between Anastrepha sp.1 males (Vacaria, Rio Grande do Sul) and Anastrepha sp.2 females (Conceição do Almeida, Bahia). Cytoplasmic incompatibility between different Wolbachia strains found in eggs of Anastrepha sp.1 and Anastrepha sp.2 has been suggested as one of the causes of their postzygotic reproductive isolation (Selivon et al 1996; Selivon et al 1999; Selivon et al 2002). Later, Wolbachia strains were also found in adults from Piracicaba (Cáceres et al 2009) as well as in Anastrepha sp.…”

The study of the species complex Anastrepha fraterculus (Af complex) in Brazil is especially important in a taxonomical, evolutionary and pest management context, because there are evidences that some of them may occur in sympatry. In this review, we analyzed the main results supporting evidences that three cryptic species occur in Brazil. The taxonomical and phylogenetic relationships based on eggshell morphology, adult morphometrics, as well as cytotaxonomy and genetic differentiations are discussed. We also review available information on sexual behavior including acoustic communication of males during courtship and sexual incompatibility; and chemical signals involved in the communication between sexes, with a special focus on sex pheromones. We examined the role of long- and short-range pheromones (male-produced volatiles and cuticular hydrocarbons, respectively), their implications in sexual isolation, and their possible use for chemotaxonomic differentiation of the putative species of the Af complex.

“…Other Rhagoletis species that seem to have persistent and multiple strain infections (although less populations are studied) are Rhagoletis pomonella (Schuler et al 2011) and Rhagoletis cingulata (Drosopoulou et al 2011a, Schuler et al 2013), along with some Rhagoletis species of Japan (Coats et al 2013). Outside Rhagoletis , the only species demonstrating persistent Wolbachia infections is Anastrepha fraterculus , (Selivon et al 2002, Cáceres et al 2009, Coscrato et al 2009, Marcon et al 2011, Martinez et al 2012). All other tephritid species are so far considered as Wolbachia -free or only exhibiting low prevalence infections.…”

The Bactrocera dorsalis species complex, currently comprising about 90 entities has received much attention. During the last decades, considerable effort has been devoted to delimiting the species of the complex. This information is of great importance for agriculture and world trade, since the complex harbours several pest species of major economic importance and other species that could evolve into global threats. Speciation in Diptera is usually accompanied by chromosomal rearrangements, particularly inversions that are assumed to reduce/eliminate gene flow. Other candidates currently receiving much attention regarding their possible involvement in speciation are reproductive symbionts, such as Wolbachia, Spiroplasma, Arsenophonus, Rickettsia and Cardinium. Such symbionts tend to spread quickly through natural populations and can cause a variety of phenotypes that promote pre-mating and/or post-mating isolation and, in addition, can affect the biology, physiology, ecology and evolution of their insect hosts in various ways. Considering all these aspects, we present: (a) a summary of the recently gained knowledge on the cytogenetics of five members of the Bactrocera dorsalis complex, namely Bactrocera dorsalis s.s., Bactrocera invadens, Bactrocera philippinensis, Bactrocera papayae and Bactrocera carambolae, supplemented by additional data from a Bactrocera dorsalis s.s. colony from China, as well as by a cytogenetic comparison between the dorsalis complex and the genetically close species, Bactrocera tryoni, and, (b) a reproductive symbiont screening of 18 different colonized populations of these five taxa. Our analysis did not reveal any chromosomal rearrangements that could differentiate among them. Moreover, screening for reproductive symbionts was negative for all colonies derived from different geographic origins and/or hosts. There are many different factors that can lead to speciation, and our data do not support chromosomal and/or symbiotic-based speciation phenomena in the taxa under study.
