BpWRKY6 regulates insect resistance by affecting jasmonic acid and terpenoid synthesis in Betula platyphylla

Plant Biotechnology Journal, Volume 23, Issue 9, Page 3682-3696, September 2025.
Summary Forest pests and diseases pose serious threats to the sustainable development of forestry. Plants have developed effective resistance mechanisms through long‐term evolution. Jasmonic acid and terpenoids play important roles in the defence response of plants against insects.

The sequence of the Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus genome

Journal of General Virology, 2001
The nucleotide sequence of the Helicoverpa armigera single-nucleocapsid nucleopolyhedrovirus (HaSNPV) DNA genome was determined and analysed. The circular genome encompasses 131403 bp, has a G+C content of 39·1 mol% and contains five homologous regions with a unique pattern of repeats.

Multiple incursion pathways for Helicoverpa armigera in Brazil show its genetic diversity spreading in a connected world

Scientific Reports, 2019
The Old World cotton bollworm Helicoverpa armigera was first detected in Brazil with subsequent reports from Paraguay, Argentina, Bolivia, and Uruguay. This pattern suggests that the H.

Planthopper protein Nlsp5 is essential for salivary sheath formation and acts as a HAMP inducing plant resistance to insects

Plant Biotechnology Journal, Volume 23, Issue 9, Page 4076-4091, September 2025.
Summary During herbivore feeding, plants can recognize herbivore‐associated molecular patterns (HAMPs) present in saliva and trigger pattern‐triggered immunity (PTI). Piercing‐sucking insects secrete gel saliva, forming salivary sheaths that aid in feeding. However, the role of proteins within these salivary sheaths in modulating plant defences remains

Exploring Plant α‐Amylase Inhibitors: Mechanisms and Potential Application for Insect Pest Control

Biotechnology Journal, Volume 20, Issue 8, August 2025.
Graphical Abstract and Lay Summary In this study, we address the importance of α‐amylases in insect pests, the possible biochemical role of α‐amylase inhibitors in plant resistance to insect pests, the molecular relationships between plant α‐amylase inhibitors and insect α‐amylases, and the biotechnological potential of proteinaceous α‐amylase ...

Susceptibility Profiles of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) to Deltamethrin Reveal a Contrast between the Northern and the Southern Benin

International Journal of Environmental Research and Public Health, 2019
Helicoverpa armigera is an indigenous species in Africa and has been reported in the destruction of several crops in Benin. Management of H. armigera pest is mainly focused on the use of synthetic pyrethroids, which may contribute to resistance selection.

Diet acts on sexual behavior development in a male moth

Insect Science, Volume 32, Issue 4, Page 1439-1452, August 2025.
Drastic changes are observed during sexual maturation characterized by the reproductive system development concomitantly to the sexual behavior ontogenesis. These modifications are under the control of internal and external factors such as food. Knowing that sexual maturation requires considerable energetic investment, diet has been shown to affect ...

The quest for the best target genes for RNAi‐mediated pest control

Insect Molecular Biology, Volume 34, Issue 4, Page 505-517, August 2025.
A major challenge for RNAi mediated pest control is the identification of the most effective RNAi target genes from the pool of ~37% of all genes that are essential. Effective RNAi target genes are predominantly highly conserved genes serving basic cellular functions such as protein degradation.
