BackgroundHelicoverpa armigera and Helicoverpa zea are major caterpillar pests of Old and New World agriculture, respectively. Both, particularly H. armigera, are extremely polyphagous, and H. armigera has developed resistance to many insecticides. Here we use comparative genomics, transcriptomics and resequencing to elucidate the genetic basis for their properties as pests.ResultsWe find that, prior to their divergence about 1.5 Mya, the H. armigera/H. zea lineage had accumulated up to more… 

Mitochondrial DNA genomes of five major Helicoverpa pest species from the Old and New Worlds (Lepidoptera: Noctuidae)

This study significantly increases the mitogenome resources for these five agricultural pests with sequences assembled from across different continents, including an H. armigera individual collected from an invasive population in Brazil.

Hybridization and gene flow in the mega-pest lineage of moth, Helicoverpa

It is shown that both H. armigera subspecies have greater genetic diversity and effective population sizes than do the other species, and no signals for gene flow are found among the six species, pointing toward the emergence of novel hybrid ecotypes.

The Genetic Basis of Gene Expression Divergence in Antennae of Two Closely Related Moth Species, Helicoverpa armigera and Helicoverpa assulta

Using this group of F1 hybrids, it is discovered that cis-related regulations play a crucial role in gene expression divergence of sex pheromone perception-related proteins.

Genome-Wide Characterization of DNA Methylation in an Invasive Lepidopteran Pest, the Cotton Bollworm Helicoverpa armigera

A genome-wide map of DNA methylation at single-nucleotide resolution for the cotton bollworm moth, Helicoverpa armigera, a globally invasive pest of agriculture is presented and it is found that methylation occurs primarily in exons, is positively correlated with gene expression, and that methylated genes are enriched for cellular “housekeeping” roles.

Multiple recombination events between two cytochrome P450 loci contribute to global pyrethroid resistance in Helicoverpa armigera

It is shown that this resistance mechanism for resistance to fenvalerate and cypermethrin is common around the world with at least eight different alleles, suggesting a potential origin for the incursion of H. armigera into the Americas.

The Genomics and Population Genomics of the Light Brown Apple Moth, Epiphyas postvittana, an Invasive Tortricid Pest of Horticulture

A genomic resource for the light brown apple moth, Epiphyas postvittana, is produced to understand the biological basis of adaptation to a high number of hosts (polyphagy) and the invasive nature of this and other lepidopteran pests.

Satellitome Analysis and Transposable Elements Comparison in Geographically Distant Populations of Spodoptera frugiperda

The results showed that most transposable elements (TEs) were commonly shared across all geographically distant samples, except for the Maverick and PIF/Harbinger elements, which have divergent repeat copies.

A high‐quality chromosome‐level genome assembly of a generalist herbivore, Trichoplusia ni

The cabbage looper genome sequence provides a valuable resource for research in a broad range of areas including fundamental insect biology, insect‐plant interactions and co‐evolution, mechanisms and evolution of insect resistance to chemical and biological pesticides, and technology development for insect pest management.

Draft nuclear genome and complete mitogenome of the Mediterranean corn borer, Sesamia nonagrioides, a major pest of maize

An assembly of the nuclear and mitochondrial genome of a pool of inbred males and females third instar larvae, based on short- and long-read sequencing provides a solid molecular basis to study insect genome evolution and to further develop biocontrol strategies against S. nonagrioides.



Population structure and gene flow in the global pest, Helicoverpa armigera

Brazilian H. armigera are derived from diverse source populations, with strong signals of gene flow from European populations, as well as prevalent signals of Asian and African ancestry, and are able to provide genomic support for the presence of the H.Armigera conferta subspecies in Australasia.

Mitochondrial DNA analysis of field populations of Helicoverpa armigera (Lepidoptera: Noctuidae) and of its relationship to H. zea

The mitochondrial DNA sequence data supports the single species status of H. armigera across Africa, Asia and Australia and the evidence for inter-continental gene flow observed in this study is consistent with published evidence of the capacity of this species to migrate over long distances.

Host specialization of the blast fungus Magnaporthe oryzae is associated with dynamic gain and loss of genes linked to transposable elements

Comparisons of host-specific M. oryzae isolates revealed gain and loss of genes as a major evolutionary mechanism driving specialization to Oryza and Setaria and transposable elements appear to facilitate gene evolution possibly by enhancing chromosomal rearrangements and other forms of genetic variation.

A Gene-Based Linkage Map for Bicyclus anynana Butterflies Allows for a Comprehensive Analysis of Synteny with the Lepidopteran Reference Genome

Strong conservation of gene assignment to chromosomes is observed, but also evidence for numerous large- and small-scale chromosomal rearrangements is observed.

Mis-splicing of the ABCC2 gene linked with Bt toxin resistance in Helicoverpa armigera

Compared the ABCC2 gene of Helicoverpa armigera between susceptible strains and a laboratory-selected strain with >1,000-fold resistance to Cry1Ac relative its susceptible parent strain, results provide the first evidence that mis-splicing of a gene encoding anABCC2 protein confers resistance to a Bt toxin.

Demographics and Genetic Variability of the New World Bollworm (Helicoverpa zea) and the Old World Bollworm (Helicoverpa armigera) in Brazil

The results suggest that sustainable management plans for the control of H. armigera will be challenging considering the high genetic diversity, polyphagous feeding habits, and great potential mobility of this pest on numerous hosts, which favor the adaptation of this insect to diverse environments and control strategies.

Molecular phylogenetics of heliothine moths (Lepidoptera: Noctuidae: Heliothinae), with comments on the evolution of host range and pest status

The frequency of evolutionary expansion and contraction in host range appears to increase dramatically at the base of the Heliothis group, in contrast to the case for earlier‐diverging lineages, and is ascribed provisionally to differential evolutionary constraints arising from contrasting life‐history syndromes.

Insect Resistance to Bacillus thuringiensis Toxin Cry2Ab Is Conferred by Mutations in an ABC Transporter Subfamily A Protein
