The Potential for Pest Management Using Plant‐Derived Signaling Compounds

Ecological Research, Volume 41, Issue 5, September 2026.
Plant‐derived signaling compounds mediate ecological interactions among plants, herbivores, their natural enemies, and neighboring plants. This graphical summary highlights three approaches to leveraging such ecological interactions for environmentally benign pest management: (1) Recruitment of natural enemies: Using herbivory‐induced plant volatiles ...

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, Volume 82, Issue 8, Page 7526-7534, August 2026.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

Pest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Progress and Challenges in Faba Bean Genetic Engineering

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Legumes are essential for global food security, serving as a vital source of plant‐based protein and playing a significant role in sustainable agricultural practices. Among legumes, faba bean (Vicia faba L.) is noteworthy due to its high‐protein content, broad climate adaptation, and suitability for cultivation in temperate regions.
