“…The absence of significant Fu's Fs east of the Alps may be attributed to the scarcity of sample locations that did not enable comparison of southern versus northern diversity, which was possible only west of the Alps, between Spain and France. However, Margaritopoulos et al (2007) showed that an expansion occurred also east of the Alps, and that northern populations were less diversified than southern ones. The evolution rate of 1.15% per Myr in Africa is hypothetical, although it is common in insects, and was deducted from the fact that it could explain the similar genetic distances between the infra-specific clades in many species of African Sesamiina by the influence of major paleoclimatic events.…”

“…Indeed, there are strong arguments supporting human introduction of S. nonagrioides . First, three molecular studies of the European population, using allozymes (Bues et al ., 1996), restriction fragment length polymorphism (Margaritopoulos et al ., 2007) and random amplified polymorphic DNA (RAPD) markers (De la Poza et al ., 2008) concluded that the insect was sedentary and a poor flyer, with strong spatial genetic structure and limited genetic exchange between distant populations. Second, in sub‐Saharan Africa, far from being a species of the northern dry savannahs, the species is limited to southern wet localities.…”

The major pest of maize in Mediterranean Europe, the stem borer Sesamia nonagrioides (Lefèbvre) (Lepidoptera: Noctuidae), has a fragmented distribution, north and south of the Sahara. The present study aimed: (1) to clarify the uncertain taxonomic status of the Palearctic and sub-Saharan populations which were first considered as different species and later on as subspecies (Sesamia nonagrioides nonagrioides and Sesamia nonagrioides botanephaga) and (2) to investigate the origin of the Palearctic population which extends from Spain to Iran, outside what is considered typical for this mainly tropical genus. We reconstructed the evolutionary history of both populations using one nuclear and two mitochondrial genes. The sub-Saharan taxon was fragmented in two isolated populations (West and East) whose mitochondrial genes were distant by 2.3%. The Palearctic population was included in the East African clade and its genes were close or identical to those of a population from Central Ethiopia, where the species was discovered for the first time. Similarly, in Africa, the alleles of the nuclear gene were distributed mainly in two West and East clades, whereas some Palearctic alleles belonged to the West clade. The Palearctic population originated therefore from East and West Africa and is the progeny of the cross between these two African populations. The main species concepts were in agreement, leading to the conclusion that the three populations are still conspecific. In the surveyed regions, the species therefore does not include two subspecies but three isolated populations. The Palearctic population suffered from severe bottlenecks that resulted in the fixation of one East African mitochondrial genome and the large reduction in its genetic diversity compared to the African populations. The data suggest that natural colonization of the Palearctic region was more plausible than human introduction. The allelic distribution of the Palearctic population was similar to that of species that survived the last glaciation. It is concluded that the African populations expanded during the last interglacial, crossed the Sahara and mixed in North Africa where fixation of the East mitochondrial genome occurred. The species then colonized Europe westward through only one eastern entrance. The coalescent-based estimate of the time to the ancestor of the Palearctic population was 108 000 years, which is consistent with this scenario.

“…Recent mitochondrial DNA (mtDNA) studies of Lepidopteran species with distribution ranges in Europe have reported no or low levels of genetic structuring in relation to distance between sample sites (e.g. Vandewoestijne et al , 2004; Margaritopoulos et al , 2007). Red admirals are much more mobile than these species.…”

1. The genetic differentiation in a migratory butterfly, the red admiral (Vanessa atalanta), was investigated to discern patterns of migratory routes used across Europe. AFLP profiles showed significant differences between almost all sampled locations, but there was no clear pattern of isolation‐by‐distance. 2. Using the software STRUCTURE 2.2, we found two distinct genotype clusters present in different frequencies at all study sites. The frequencies of these genotypic clusters varied significantly between years within the same site. Remarkably few individuals were of mixed ancestry, indicating that some isolating mechanisms are present. Twenty‐seven mtDNA haplotypes were identified but they showed no geographic structure, nor were they related to either of the two genotype clusters identified in the AFLP data. 3. Most field observations of migrating red admirals suggest a regular north–south migration pattern in Europe. Our data indicate both long‐distance migration and a more variable pattern in orientation, since the composition of the two genotypic clusters shows dramatic variation between sites and years in the northern part of the distribution range.

“…This pest has been traditionally regarded as a rather sedentary pest , Eizaguirre et al 2004, Margaritopoulos et al 2007), likely to develop genetic isolation between geographical regions. Genetic differentiation between S. nonagrioides populations in European countries has been reported using different molecular markers (Bues et al 1996, Kourti 2006, Leniaud et al 2006, Margaritopoulos et al 2007, De La Poza et al 2008. reconstructed the evolutionary history of Palaearctic and Sub-Saharan populations of S. nonagrioides using one nuclear and two mitochondrial genes and concluded that the isolated Iranian population appears to have recently originated from a population of eastern Europe origin.…”

Although the stem borer Sesamia nonagrioides (Lefèbvre, 1827) is one of the most destructive agricultural pests in South and Southwest Iran, the structure of these populations is not yet well understood. In this study, we sequenced two mitochondrial genes (CO1 and Cyt-b) of populations collected in cultivated sugarcane and rice in South and Southwest Iran. These genetic data of Iranian populations were compared with those of already published data from West Palaearctic (Africa and Europe). To testing the intra-and inter-population variations, different population analyses (e.g. haplotype network, haplotype and nucleotide diversity) were executed. Our results indicate a considerable genetic variation in Iranian populations of S. nonagrioides, which supports the long-term establishment of S. nonagrioides populations in Iran versus a recent invasion. Close genetic relationship of Iranian population of S. nonagrioides with a population of Central Ethiopia supports the scenario of the origin of this species from Africa to western Asia through the Trans-Arabian bridge. Our results help to explain the variation in pest status of S. nonagrioides observed across its distribution range in Iran.Key words: CO1, Cyt-b, gene flow, haplotype, population genetics. INTRODUCTIONThe stem borer Sesamia nonagrioides (Lefèbvre, 1827) (Lepidoptera: Noctuidae) is one of the most damaging sugarcane pests in sugarcane agro-industries of Khuzestan province (Southwest Iran) since 1950's. It is also a pest of maize and rice in provinces of Khuzestan and Fars (South Iran) where it completes four to five generations annually (Khanjani 2004, Cherghali et al. 2015. The pest status of S. nonagrioides on different crops varies across its distribution range in Iran (Cherghali et al. 2015). Pest management strategies of this economic pest in sugarcane fields of south-western Iran include releasing the egg parasitoid wasp Telenomus busseolae Gahan (Hym., Scelionidae) (Jamshidnia et al. 2010). However, this wasp cannot perform a successful biologiActa Zool. Acad. Sci.

Pesticides are used by farmers in the case of heavy damage to maize and rice. Management practices of S. nonagrioides in Iran ignore the possible existence of genetic diversity among populations of this pest and its range of distribution.The species S. nonagrioides, is considered one of the most important pests of maize in many countries around the Mediterranean region where it is known as the Mediterranean corn borer or corn stalk borer (De La Poza et al. 2008). This pest has been traditionally regarded as a rather sedentary pest , Eizaguirre et al. 2004, Margaritopoulos et al. 2007), likely to develop genetic isolation between geographical regions. Genetic differentiation between S. nonagrioides populations in European countries has been reported usi...
