Resistance status of lepidopteran soybean pests following large-scale use of MON 87701 × MON 89788 soybean in Brazil

Scientific Reports, 2021
Widespread adoption of MON 87701 × MON 89788 soybean, expressing Cry1Ac Bt protein and glyphosate tolerance, has been observed in Brazil. A proactive program was implemented to phenotypically and genotypically monitor Cry1Ac resistance in Chrysodeixis ...

Midgut Transcriptome Analysis ofClostera anachoretaTreated with Cry1Ac Toxin [PDF]

, 2019
AbstractClostera anachoretais one of the important Lepidoptera insect pests in forestry, especially in poplars woods in China, Europe, Japan and India, et al, and also the target insect of Cry1Ac toxin and Bt plants. In this study, by using the different dosages of Btcry1Ac toxin to feed larvae and analyzing the transcriptome data, we found six genes ...

Integrated Pest Management in Pigeonpea: Progress and Prospects

Journal of Applied Entomology, Volume 149, Issue 4, Page 661-681, May 2025.
ABSTRACT Pigeonpea is one of the world's most important grain legume crops. Mostly grown and consumed in India, where it is a staple food, pigeonpea production also occurs elsewhere in Asia, Africa, Latin America and Australia. Despite widespread cultivation and staple food status, pigeonpea yields have barely increased over the last half century.

The investigation of a recombinant GalNAc binding protein from bacillus thuringiensis as a tool for glycan analysis and detection [PDF]

, 2011
Changes in the structures of glycans on the surfaces of eukaryotic cells can be important biomarkers for developmental or disease states. Improved methods are needed for the detection and analysis of alterations in glycan structures. Carbohydrate binding

Midgut microbiota and associated metabolites played a synergistic role in the Vip3Aa19 toxicity in Spodoptera frugiperda

New Plant Protection, Volume 2, Issue 1, March 2025.
Insect gut bacteria and their metabolites can enter the hemocoel of the larvae through the damage in the midgut, resulting in increased mortality of the larvae. In particular, some specific metabolic can induce apoptosis, thus playing a synergistic role in the insecticidal activity of Bt protein.

Activation of Bt Protoxin Cry1Ac in Resistant and Susceptible Cotton Bollworm

PLOS ONE, 2016
Crystalline (Cry) proteins from Bacillus thuringiensis (Bt) are used extensively for insect control in sprays and transgenic plants, but their efficacy is reduced by evolution of resistance in pests. Here we evaluated reduced activation of Cry1Ac protoxin as a potential mechanism of resistance in the invasive pest Helicoverpa armigera.
