RNA activation in insects: From emerging evidence to molecular applications

Insect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Potential distribution of Spodoptera frugiperda (J.E. Smith) in China and the major factors influencing distribution

Global Ecology and Conservation, 2020
Fall armyworm, Spodoptera frugiperda (J.E. Smith) is one of the most important agricultural pests in the world. At the end of 2018, S. frugiperda was first found in Yunnan, China, and then it had spread rapidly to 19 provinces and posed a serious threat ...

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

The Individual and Combined Entomopathogenic Activity of a Spodoptera frugiperda Multiple Nucleopolyhedrovirus and a Type I Spodoptera frugiperda Granulovirus on S. frugiperda Larvae

Viruses
The bioinsecticidal activity of several doses of a Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV-CH-32; LD10, LD50, and LD90) and a Type I Spodoptera frugiperda granulovirus (SfGV-CH13; LD50 and LD90), alone and in co-infection, was evaluated on S. frugiperda larvae.

Perceptions, challenges and determinants of management strategy choices for combating fall armyworm (Spodoptera frugiperda) infestation in Ghana

Pest Management Science, Volume 82, Issue 9, Page 9107-9118, September 2026.
Despite high awareness of fall armyworm, a significant gap remains in the use of sustainable and effective control measures. Farmers predominantly perceive synthetic pesticides as ideal despite studies highlighting botanical and traditional methods as more sustainable.

Bt agave: why it is time to explore a new biotechnological frontier

Pest Management Science, Volume 82, Issue 9, Page 8053-8063, September 2026.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.
