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.

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.

Integrated Multi‐Omic Analyses Uncover a Regulatory Link Between Photosynthesis and Drought Tolerance in Field‐Grown Sorghum

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming and increasing water scarcity pose major challenges to agriculture, emphasising the need to translate stress‐biology insights into the development of drought‐resilient cultivars. In this study, we evaluated a panel of six diverse sorghum (Sorghum bicolour) accessions grown under field‐imposed drought conditions in central ...

Comparative evaluation of Bt and non-Bt cotton varieties against cotton Bollworm infestation in Ethiopia

Cogent Food & Agriculture
The cotton bollworm is a complex biotic problem that causes 36–60% yield loss. Controlling this pest was practiced by insecticides, but efforts have been made through genetic modification to reduce pesticide use and environmental pollution.

Three‐dimensional digital quantitative analysis of periodontal and peri‐implant phenotype—A narrative review

Periodontology 2000, EarlyView.
Abstract 3D digital evaluation of the periodontal and peri‐implant tissue, including CBCT, intraoral scanning, optical surface scanning, and ultrasonography, is being used in the clinical arena with increasing frequency. Thus, to validate the utilization of 3D digital analysis for this purpose, a critical evaluation of the reliability of digital ...

The regulatory frameworks surrounding CRISPR‐edited papaya and their impact on international commerce

Journal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6262-6270, 30 August 2026.
Abstract The papaya tree (Carica papaya L.), native to the Americas, is cultivated in tropical regions and holds substantial economic importance, with an estimated export volume of 365 000 t in 2023. However, diseases caused by viruses, fungi, bacteria, and nematodes can lead to severe losses.

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

Insect resistance management in Bacillus thuringiensis cotton by MGPS (multiple genes pyramiding and silencing)

Journal of Cotton Research, 2020
The introduction of Bacillus thuringiensis (Bt) cotton has reduced the burden of pests without harming the environment and human health. However, the efficacy of Bt cotton has decreased due to field-evolved resistance in insect pests over time.
