“…The mosquitoes observed in the present instance exhibit a similarity with the findings of earlier studies in India (Kant et al 1998;Sunish & Reuben 2002;Sunish et al 2006) or elsewhere (Muturi et al 2008;Stoops et al 2008;Lytra & Emmanouel 2014;Ohba et al 2013Ohba et al , 2015 though the species richness remained low. This may possibly due to the sampling error or due to the restricted space included in the sampling strategy.…”

“…This study was carried out using Burdwan district as the geographical area, and may represent a specific region where these species were available. While in the studies Muturi et al 2008;Stoops et al 2008;Lytra & Emmanouel 2014;Ohba et al 2013Ohba et al , 2015 being compared with the present one included a larger sampling area and time, the present study was accomplished within a short spatial range. However, when compared with the findings with the similar spatial range of habitat, the mosquito species richness remained comparable .…”

“…Empirical observations on the rice field mosquitoes in India and countries where paddy rice cultivation is a normal practice, the abundance of Anopheline and Culicine mosquitoes are guided by the environmental factors and the habitat permanence of the cultivable lands (Kant et al 1992(Kant et al , 1998Sunish & Reuben 2002;Banerjee & Chandra 2004;Keiser & al. 2005;Sunish et al 2006;Ohba et al 2013Ohba et al , 2015Lytra & Emmanouel 2014) cial determinant for the future abundance and dominance. Earlier studies have noted that the colonization of different species of mosquitoes occurs in sequence and the dominance pattern changes as a function of time (Chandlar & Highton 1975;Bang & Pant 1984;Begum et al 1986).…”

“…Entomological surveillance is a pre-requisite for estimating the variations in the mosquito immatures in the rice fields and allied habitats (Chase and Knight 2003;Derraik 2004;Keiser et al 2005;Dale & Knight 2008;Hassan et al 2010;Li et al 2011;Ohba et al 2013Ohba et al , 2015Amarasinghe and Weerakkodi 2014;Amarasinghe & Dalpadado 2014;Lytra & Emmanouel 2014). Random sampling of the selected sites in the rice fields are carried out to infer about the relative abundance of different mosquito species in space and time Ohba et al 2013Ohba et al , 2015Lytra & Emmanouel 2014).…”

“…Random sampling of the selected sites in the rice fields are carried out to infer about the relative abundance of different mosquito species in space and time Ohba et al 2013Ohba et al , 2015Lytra & Emmanouel 2014). Rice fields are heterogeneous habitats with changing community composition with time coinciding with the cultivation period and the harvest periods (Kant et al 1992;Sunish et al 2006;Yasuoka & Levins 2007;Muturi et al 2008;Watanabe et al 2013;Ohba et al 2013Ohba et al , 2015Lytra & Emmanouel 2014). During the wet conditions, the rice fields and allied habitats provide congenial conditions for the breeding of different species of vector and pest mosquito species Sunish et al 2006;Yasuoka & Levins 2007).…”

The mosquito Culex tritaeniorhychus is an established vector of Japanese encephalitis in India and many Asian countries. Entomological monitoring enables estimation of the abundance of the vector mosquitoes and therefore aids in vector management and disease control. In compliance with this proposition, an assessment of the pupal productivity of the mosquito C. tritaeniorhynchus was made from selected rice fields of West Bengal, India. The results are expected to provide the present status of mosquitoes in an endemic region of Japanese encephalitis. In course of sampling of the rice fields, the mosquito C. tritaeniorhyhchus was found in abundance with other mosquitoes like Culex bitaeniorhynchus, Anopheles subpictus, Anopheles vagus, Anopheles barbirostris. Application of multivariate analysis indicated that the plant height, water depth and temperature could explain the variations in the pupal productivity of C. tritaeniorhynchus in rice fields. The correspondence of the immature abundance of C. tritaeniorhynchus with plant height suggests persistence of the population throughout the paddy rice cultivation period. Using the plant height as an indicator, the abundance of the mosquito C. tritarniorhynchus can be predicted enabling application of appropriate strategies for population intervention and thus the possibility of the disease.

Purpose Mosquitoes are important vectors of pathogens that can affect humans and animals. Culex tritaeniorhynchus is an important vector of arboviruses such as Japanese encephalitis virus, West Nile virus among various human and animal communities. These diseases are of major public health concern and can have huge economic and health burdens in prevalent countries. Although populations of this important mosquito species have been detected in the Mediterranean and Aegean regions of Türkiye; little is known about its population structure. Our study is to examine the population genetics and genetic composition of Cx. tritaeniorhynchus mosquitoes collected from several localities using cytochrome oxidase subunit I (COI) and the NADH dehydrogenase subunit 5 genes (ND5). This is the first extensive study of Cx. tritaeniorhynchus in the mainland Türkiye with sampling spanning many of provinces. Methods In this study, DNA extraction, amplification of mitochondrial COI and ND5 genes and population genetic analyses were performed on ten geographic populations of Culex tritaeniorhynchus in the Aegean and Mediterranean region of Türkiye. Results Between 2019 and 2020, 96 samples were collected from 10 geographic populations in the Aegean and Mediterranean regions; they were molecularly analyzed and 139 sequences (50 sequence for COI and 89 sequence for ND5) were used to determine the population structure and genetic diversity. For ND5 gene region, the samples produced 24 haplotypes derived from 15 variable sites and for COI gene region, 43 haplotypes were derived from 17 variable sites. The haplotype for both gene regions was higher than nucleotide diversity. Haplotype phylogeny revealed two groups present in all populations. AMOVA test results show that the geographical populations were the same for all gene regions. Results suggest that Cx. tritaeniorhynchus is a native population in Türkiye, the species is progressing towards speciation and there is no genetic differentiation between provinces and regions. Conclusion This study provides useful information on the molecular identifcation and genetic diversity of Cx. tritaeniorhynchus; these results are important to improve mosquito control programs.
