“…For the clade/cluster or delimited species corresponding to C. punctiferalis (sensu Shashank et al 2018), the pairwise genetic distances ( p -distance) among mtCOI haplotypes were calculated using MEGA 11(Tamura et al, 2021). To further evaluate intraspecific genetic variation, we used these haplotypes as queries and recursively blasted the GenBank with the smallest interspecific distance found among the species delimited in the present study as a filtering threshold.…”

“…Similarly, C. punctiferalis in India feeding on castor and cardamom represented two different lineages (Chakravarthy et al, 1991). The cardamom population was lately recognized as a distinct species C. sahyadriensis which differed from C. punctiferalis by genetic distances of no less than 6.00% (Shashank et al, 2018). Thus, it is clear that C. punctiferalis represents a species complex including multiple species of very similar morphology, variable ecotypes, and overlapping host ranges (Armstrong, 2010).…”

Species are not only the fundamental unit of taxonomy but also the basic unit of pest management. Insects ofConogethesare important agricultural and forestry pests. However, species boundaries withinConogethesoften appear obscure. In the present study, we re-evaluated the species status ofConogethesby applying three species delimitation approaches based on the mitochondrial DNA sequences, with particular emphasis on the yellow peach mothC. punctiferalis(Guenée, 1854). We first optimized species delimitation and inter-species genetic divergence threshold using a DNA barcoding dataset. Our results revealed that several nominal species ofConogethesspecies harbored deeply diverged mitochondrial lineages which were recognized as independent species by the species delimitation methods. The p-distance between the delimited putative species ranged from 0.0159 to 0.1321 with a mean of 0.0841. Then we refined the species status ofC. punctiferalisusing the smallest interspecific distance threshold based on a geographically comprehensive population-scale dataset. This procedure narrowed the species concept ofC. punctiferalisto a genetically coherent unit. Further investigation of its intraspecific divergence in the geographic context revealed that the refinedC. punctiferaliswas still widely distributed with the same or highly similar mitochondrial haplotypes occurring across South and East Asia.

“…In recent times many Indian taxonomists are integrating DNA barcodes with isolated species descriptions [ 35 – 37 ]. These include reviews, revisions of small, specific groups of insects at the generic level [ 38 , 39 ] and studies resolving cryptic species problems [ 6 ]. Taxonomists should add DNA barcode data to new species descriptions and taxonomic revisions.…”

To support this range of applications, high-quality well curated reference libraries, based on voucher specimens are necessary [ 5 ].…”

DNA barcoding of insects from India: Current status and future perspectives

Insect fauna occupy the largest proportion of animal biodiversity on earth, but the assessment or quantification in terms of species diversity is far from complete. Several recent studies have demonstrated the rapid pace at which insect population decline is occurring. There is an urgent need to document and quantify the diversity of insect fauna for a proper understanding of terrestrial ecosystems. This can be achieved by using modern technology to identify species much faster than relying on traditional methods alone. In line with this, the molecular approach through DNA barcoding coupled with morphological identification needs to be focused and accelerated. The present paper describes the current status of barcoding of insect species in India along with the gaps that need to be remedied. This analysis shows that barcoded specimens cover a very meagre proportion of less than 3.73% of the known taxa/described species and the most represented orders are Lepidoptera and Hemiptera followed by Diptera and Coleoptera. There is a need to expedite insect species discovery and documentation in a collaborative mode between traditional taxonomists and molecular biologists, to accomplish the DNA barcoding of all known insect taxa from India.

“…Since then Conogethes populations feeding on castor and cardamom have been included under the species punctiferalis. But in 2018, a new species C. sahyadriensis feeding on cardamom was delineated from closely related species of Conogethes (Shashank et al, 2018).…”

Aim: The aim of this study was to develop species specific marker for quick identification of two Conogethes species and to study their molecular diversity. Methodology: Species-specific markers were developed using mitochondrial cytochrome oxidase 1 (COI) partial gene sequences of Conogethes punctiferalis and C. sahyadriensis and they were validated. Phylogenetic tree was constructed using MEGA X program, tree robustness was evaluated by bootstrapping with 1000 replicates with all sequences of C. punctiferalis and C. sahyadriensis. Results: Bioinformatic analysis of C. punctiferalis and C. sahyadriensis COI sequences revealed that they have sufficient genetic variability to develop species specific marker. The COI based species-specific markers amplified an expected fragment size of 333 bp for C. punctiferalis and 522 bp for C. sahyadriensis, which clearly differentiate these two species. Interpretation: The species specific marker developed in this study will be useful in quick identification of C. punctiferalis and C. sahyadriensis. The use of COI gene as a marker can provide a better estimate of genetic diversity, as it is maternally inherited and can be helpful to understand evolutionary processes. Key words: Conogethes punctiferalis, C. sahyadriensis, MtCOI, Molecular diversity, Species-specific marker
