Pesticide Residues: Impacts on Fauna and the Environment

Pesticide residues are the traces of pesticide compounds that remain on or in the crop, water, soil and air after the application. Pesticide residues get into the environment as a result of application or by accident and can be found in the air, water and soil. Pesticide residues, if present in air, soil and water can pose a serious threat to biological diversity and human health. After depositing in the environment, the pesticides start to break down and forms metabolites that are more or less toxic. Pesticide residues decline as the pesticide breaks down over time, therefore the levels of residues are highest immediately after the application and diminish as the crops continue to grow. When exposed to sunlight or microorganisms in the soil, most pesticides degrade easily however, the utmost number of pesticides after application scatter into non-target areas or leach into groundwater or move in surface runoff by misuse and misapplication while handling or spraying. The impact of widespread usage of chemical pesticides has made an uncountable number of effects on human health, environment and other life forms and has turned into a serious issue across the globe. The present study aims to present an introduction to the environmental pesticide residues and various aspects highlighting their impact on nature and biodiversity

Insecta, Lepidoptera, Noctuidae, Catocalinae: new records from the state of Tamil Nadu and whole of India

Adult moths of the Noctuidae subfamily Catocalinae from Tamil Nadu, Western Ghats are reviewed. During this study, eleven species have been newly recorded from Tamil Nadu (Western Ghats) and one species has been recorded from India for the first time

Checklist of the superfamily Noctuoidea (Insecta, Lepidoptera) from Tamil Nadu, Western Ghats, India

A checklist of the superfamily Noctuoidea (Erebidae, Noctuidae, Euteliidae, and Nolidae) from Nilgiris Biosphere Reserve and Kodaikanal Hills in Western Ghats, Tamil Nadu is presented. We collected noctuoid moths monthly from June 2010 to December 2014. We collected 9095 individuals (5242 males and 3853 females) belonging to 188 species, 106 genera, 5 subtribes, 25 tribes, 26 subfamilies and 4 families. The most species-rich families were Erebidae (106 species) and Noctuidae (51 species). The Erebinae was found to be the richest subfamily with 64 species. Additional sampling might reveal 2–3 times more species

Comparative analysis of the mitochondrial genome of Hypospila bolinoides and Lygephila dorsigera (Lepidoptera: Noctuoidea: Erebidae), with implications for their phylogeny

To analyse the phylogenetic relationships of members of the family Erebidae, the mitogenomes of two species namely, Hypospila bolinoides Guenée, 1852 and Lygephila dorsigera (Walker, 1865) were sequenced. H. bolinoides and L. dorsigera have circular genomes that are 15,640 bp and 15,567 bp long, respectively. Despite their different lengths, both genomes contain an identical gene order, which includes 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes and an A+T-rich region. The nucleotide composition of the H. bolinoides mitogenome vis-à-vis the A+T rich region was 80.08%, which is higher than that of L. dorsigera (78.03%). The AT skew and GC skew were mostly negative for both species. The A+T-rich regions of H. bolinoides and L. dorsigera were 287 bp and 383 bp long, respectively, and confined to common characteristics of Noctuoidea. Concatenated sequences of 13 PCGs from 170 taxa belonging to the five families of the superfamily Noctuoidea and two butterfly mitogenomes used as outgroups were utilized for Bayesian inference (BI) and Maximum Likelihood (ML) analyses. The first-ever comprehensive analysis of the mitogenomes of the genera Lygephila (Billberg, 1820) and Hypospila (Guenée, 1852) revealed that the superfamily Noctuoidea has a well supported monophyletic relationship with (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae))). In support of previous partial genome analyses, the present study provides phylogenomic evidence that L. dorsigera, hitherto classified as a member of the subfamily Erebinae, can be placed within the subfamily Toxocampinae

Complete mitochondrial genome sequence of fruit-piercing moth Eudocima phalonia (Linnaeus, 1763) (Lepidoptera: Noctuoidea)

The complete mitochondrial genome of the fruit piercing moth Eudocima phalonia (Linnaeus, 1763) (Lepidoptera: Noctuoidea) was sequenced and characterized (Genbank Accession No: KY196412). The complete mitogenome is a circular molecule of 15,575 bp length, consisting of 13 protein-coding genes (PCGs), two ribosomal RNA genes (rrnS and rrnL), 22 transfer RNA (tRNA) genes and an A + T-rich region (D-loop). The nucleotide composition of the genome is highly A + T biased, accounting for 80.67% of nucleotides. All tRNAs have putative secondary structures that are characteristic of mitochondrial tRNA. Most of the PCGs were initiated by typical ATN codons. Five genes were initiated by unusual codons. Cox1 gene was initiated by an unusual CGA codon and terminated by the typical stop codon GAA. Six genes ended with a single T. The A + T-rich region of 336 bp consisted of repetitive sequences, including two ATAGA motifs, a 19 bp poly-T stretch and three microsatellite-like regions ((TA)4, (TA)6 and two (TA)7). Moreover, three large tandem (one 40 bp and two 25 bp) repeated elements were identified in A + T-rich region. Phylogenetic analysis using PCGs revealed that Superfamily Noctuoidea is a monophyletic group
