Adaptive Introgression across Semipermeable Species Boundaries between Local Helicoverpa zea and Invasive Helicoverpa armigera Moths

bioRxiv, 2019
Hybridization between invasive and native species has raised global concern given the dramatic increase in species range shifts and pest outbreaks due to climate change, development of suitable agroecosystems, and anthropogenic dispersal.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, EarlyView.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Pathogenecity of Metarhizium anisopliae on Helicoverpa armigera larvae instars

International Journal of Agricultural Invention, 2020
Studies on pathogenicity of M. anisopliae against Ist - VIth instar H. armigera larvae revealed that larval mortality. The effect of Metarhizium anisopliae spore/ml against Helicoverpa armigera larval instars was significantly higher recorded showed that in the results revealed that all the treatments were significantly larval mortality.

Characterization of a novel member of genus Iflavirus in Helicoverpa armigera [PDF]

Journal of Invertebrate Pathology, 2017
The cotton bollworm, Helicoverpa armigera, is one of the most important agricultural pests of many economic crops worldwide. Herein, we found a novel single-strand RNA virus by RNA-Seq and Polymerase Chain Reaction (PCR) method in H. armigera named Helicoverpa armigera iflavirus (HaIV), which possessed a genome with 10,017 nucleotides in length and ...

Spatial Interpolation in Applied Insect Ecology: A Review, Including Guidelines and Datasets for Practical Use

Journal of Applied Entomology, EarlyView.
ABSTRACT Spatial interpolation represents a fundamental approach in applied insect ecology, offering insight into species distributions and supporting biodiversity analysis, pest management and disease vector mapping. Insects—including important pollinators—face escalating threats due to habitat loss, climate change and anthropogenic pressures. As data‐

Phylogeography of the Recent Expansion of Helicoverpa armigera (Lepidoptera: Noctuidae) in South America and the Caribbean Basin

Annals of the Entomological Society of America, 2019
The Old World bollworm, Helicoverpa armigera (Hübner), is one of the most destructive agricultural pests worldwide. It was first recorded in Brazil in 2013, yet despite this recent introduction, H.

Assessment of genetic variability and heritability for yield traits in chickpea (Cicer arietinum L.) genotypes

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Chickpea (Cicer arietinum L.) is a vital pulse crop cultivated globally, especially in arid and semiarid regions. This study aimed to assess genetic variability, heritability, and interrelationships among yield and yield‐related traits in 18 advanced chickpea genotypes using a randomized complete block design with three replications during the

Life history and fitness costs in the lambda‐cyhalothrin resistant clone of English grain aphid, Sitobion avenae (Fabricius)

Pest Management Science, Volume 81, Issue 9, Page 5717-5726, September 2025.
The purpose of this study is to investigate the life‐history traits and fitness costs of English grain aphid clones that are resistant to lambda‐cyhalothrin (SA3) and susceptible to it (SA27). Overall, the results showed that there are differences in the stages of development, survival, reproduction and population growth.
