“…They suggested a contraction-expansion scenario during climatic oscillation leads to geographical overlaps of two mtDNA clades created the allopatric population of Asian elephants in India, Sri Lanka and Myanmar. In the case of weaver ant in Bangladesh, as both the Indian and SE Asian types were dominated in Western and Eastern part of the country, respectively and there was not such a big border of separating those two populations (Rahman et al 2017a).…”

“…The phylogenetic study of O. smaragdina based on mitochondrial Cytb and CO1 genes identified two major types where Indian types occurred mainly in India and Sri Lanka while the Southeast Asian (SE Asian) types have been observed in most of the SE Asian countries including Bangladesh (Azuma et al 2006(Azuma et al , 2002. However, recent phylogenetic study revealed the occurrence and dominancy of Indian type in the western part (Rahman et al 2017a) and SE Asian types in the eastern part and overlapping population of O. smaragdina in the central part of Bangladesh (Rahman et al 2017b) that can lead the chance of hybridization. Recently, for inferring the evidence of hybridization a comprehensive view of evolutionary history by analyzing nuclear and mitochondrial DNA between species level phylogeny in Hymenoptera was found effective and has been used extensively (Roos et al 2011;(Ascher et al 2001;Cameron and W illiams, 2003).…”

Background: The two types of Asian weaver ant species, Oecophylla smaragdina, Indian types and Southeast (SE) Asian types can co-occur in the same habitat. Previous study on mtDNA based phylogenesis of O. smaragdina in Bangladesh has revealed the presence of the mixture of both Indian and SE Asian type of O. smaragdina. However, the nuclear DNA based study showed some inconsistency leading the chance of hybridization as colonies encountered from two localities contained O. smaragdina workers from more than one type as identified via longwave length rhodopsin (LWRh) and mitochondrial COI and Cytb gene analysis. The purpose of present study was to detect hybridization status and to find out the identical allele for Indian and SE Asian type of O. smaragdina from different colonies. Method: A total of seven O. smaragdina colonies had been collected from Bangladesh during 2013 to December 2016. Microsatellite analysis were performed for Gene mapping and heterozygosity study with 11 microsatellite loci through electropherogrum study generated by peak scanner software.Result: Among 11 microsatellite loci, two loci, MS 8.24 and MS 6.45 provided the identical allele position for Indian and SE Asian types while no allelic position were identified with nine microsatellite loci. The results inferred that weaver ant of both Indian and SE Asian type engage in bidirectional interspecific gene flow. The strong possibility of hybridization between these two types is inferred, which indicates that barriers to hybridization do not exist or can be completely overcome. This is unexpected, given that they are non-sister species and broadly sympatric in nature. These findings also indicate the possible occurrence of hybrid-hybrid crosses in some localities of weaver ant, a phenomenon rarely observed in ants.

The weaver ant species, Oecophylla smaragdina, is widely distributed from India through Southeast Asia to northern Australia including many tropical Western Pacific islands. The ant is arboreal observed in natural forests, fruit orchards and homestead woodlands, and is one of the important biological control agents. A recent phylogenetic study of O. smaragdina showed that the species is divided into 7 groups based on mtDNA and that the Bangladesh populations belong to SE Asian mainland clade despite of its geographical proximity to India. However, the samples analyzed from Bangladesh were limited and distribution pattern of Bangladeshi populations was not clearly presented. The present study aims to reveal the phylogeographic aspect of O. smaragdina in Bangladesh including phylogenetic analysis, haplotype network analysis and divergence time estimation as well as hybridization detection based on extensive materials. The sampling was executed according to zonation of 5 areas which are demarcated by 3 main rivers during the years 2013 to 2017. Ninety five colonies from 87 localities of 47 Districts were collected. The molecular analyses were carried out using 2 mitochondrial loci: Cytochrome b oxidase subunit 2 (Cytb) consisting of 507 bp and Cytochrome c oxidase subunit I (COI) consisting of 639 bp. The possibility of occurring hybridization of O. smaragdina in the zone of contact was examined by using LW Rh of nuclear DNA and microsatellite markers. The phylogenetic analysis of 84 colonies revealed that 47 are the Indian clade (Indian type) and 37 are the SE Asian mainland clade (SE Asian type). The distribution of mtDNA typesshowed that the western parts of Bangladesh is predominantly occupied by the Indian type, whereas, the eastern part was dominated by the SE Asian type, and the central parts is the mixture of both types. The haplotype network analysis indicated that a total of 25 haplotypes ii were identified in Bangladesh based on COI genes, comprises 13 and 12 of Indian and SE Asian types, respectively. The divergence time analysis in Bangladesh populations, resulted that Indian type diverged ca. 2.2 Ma and SE Asian type diverged ca. 0.20 Ma corresponding to early to late Pleistocene. Two microsatellite markers, MS 6.45 and MS 8.24 possibly detected identical allele between Indian and SE Asian types of Oecophylla population in Bangladesh.Nuclear gene sequences from LW Rh region showed inconsistency of Indian and SE Asian types from two colonies of the overlapped zone. Discordance between mitochondrial and nuclear DNA genes suggests the possibility of hybridization in the zone of contact.The results of the study suggest a scenario of dispersal: 1) before Last Glacial Maximum (LGM), the haplotypes observed in Bangladesh would be already established; 2) during theLGM, the Bengal Delta supposed to be vacant for Oecophylla smaragdina distribution because the northern limit of the species would be located down to the south; 3) after the LGM, the isolated populations in southern refuge areas of India and SE Asia ...

“…However, the occurrence of Indian type from Bangladesh has been recorded (Rahman et al 2017b).

In Bangladesh, the occurrence of different types implies the chance of hybridization.…”

Background: Oecophylla smaragdina is distributed from India, SE Asia and Australia including many tropical Islands. A recent phylogenetic study based on mitochondrial DNA analysis reveals that Bangladesh is the overlapping zone of both Indian and Southeast Asian type of O. smaragdina. These two different lineages of Indian and SE Asian type have the opportunities of creating the zone of contacts, but no such data was found. In this study, shed light was given to reveal the chance of hybridized colony of O. smaragdina in Bangladesh. Methods: To asses the hybridization scenario, 28 O. smaragdina colony from 27 localities in Bangladesh were analyzed using Longwave length Rhodopsin (LWRh) nuclear gene sequences and was compared with the mtDNA sequences, which was collected from the same localities and deposited into NCBI GenBank. Results: The inconsistency between mitochondrial and nuclear gene types was observed from two colonies of the overlapped zone of contact. These two colonies were identified as SE Asian type by mtDNA analysis however, by nuclear DNA analysis; it was identified as Indian type. These significant discrepancies within the colony suggested the possibility of hybridization of weaver ant in Bangladesh.
