Field assessment of the effects of Cry1Ac and Cry1Ac + Cry2Ab Bt cotton against pink bollworm in Pakistan

Journal of Cotton Research
Background Transgenic cotton producing toxins derived from the bacterium Bacillus thuringiensis (Bt) is used globally to manage insect pests, including the pink bollworm, Pectinophora gossypiella, one of the most damaging pests of cotton.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Bacteriophage P22 Virus‐Like Particles as Nanoscale Protein Scaffolds for Plant Synthetic Biology

Plant Biotechnology Journal, EarlyView.
ABSTRACT Advancing the utility of plant synthetic biology requires the continued development of protein engineering tools. Self‐assembling protein compartments, such as virus‐like particles (VLPs), provide versatile scaffolds for synthetic biology. However, few plant‐expressed VLPs have demonstrated broad amenability to protein engineering, restricting

Effects of pupal hypoxia duration and holding temperature on quality control parameters of sterile Queensland fruit fly

Pest Management Science, Volume 82, Issue 9, Page 8382-8391, September 2026.
Queensland fruit fly pupae tolerate hypoxia up to 2 days without compromising quality. Prolonged hypoxia, especially at 25 °C, reduces emergence and flight ability. Storage at 18 °C is recommended. Abstract BACKGROUND The sterile insect technique is used to eradicate outbreaks of Queensland fruit fly (Q‐fly) Bactrocera tryoni (Froggatt) in fruit‐fly ...

Using ecoinformatics to evaluate the impact of crop and herbicide rotations on herbicide intensity

Pest Management Science, Volume 82, Issue 9, Page 8734-8746, September 2026.
Maize fields with cotton in rotation receive lower herbicide application than fields without cotton. Abstract BACKGROUND Crop rotation is a central component of integrated weed management (IWM) under real‐world conditions, yet its impact on herbicide use remains unclear. To address this challenge, we developed an ecoinformatics‐driven analysis approach

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
