Toxicity of Cry- and Vip3Aa-Class Proteins and Their Interactions against <i>Spodoptera frugiperda</i> (Lepidoptera: Noctuidae). [PDF]
Toxins (Basel)The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), is one of the most important insect pests affecting corn crops worldwide. Although planting transgenic corn expressing Bacillus thuringiensis (Bt) toxins has been approved as being effective against FAW, its populations’ resistance to Bt crops has emerged in different locations around the ...

Cry1Ac and Vip3Aa proteins from Bacillus thuringiensis targeting Cry toxin resistance in Diatraea flavipennella and Elasmopalpus lignosellus from sugarcane [PDF]
PeerJ, 2017 The biological potential of Vip and Cry proteins from Bacillus is well known and widely established. Thus, it is important to look for new genes showing different modes of action, selecting those with differentiated entomotoxic activity against Diatraea ...

pH regulates pore formation of a protease activated Vip3Aa from Bacillus thuringiensis
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2017 Vip3Aa insecticidal protein is produced from Bacillus thuringiensis and exerts a broad spectrum of toxicity against lepidopteran insect species. Although Vip3Aa has been effectively used as part of integrated pest management strategies, the mechanism of the toxin remains unclear. Here, we investigated the effect of pH in a range from 5.0 to 10.0 on the

Influence of Bt and environmental factors on Fusarium ear rot in maize
Crop Science, Volume 65, Issue 4, July/August 2025.Abstract Fusarium verticillioides is responsible for Fusarium ear rot (FER) and fumonisin (FUM) in maize (Zea mays L.). Multiple factors, including drought stress, humidity, and insects, influence the severity of FER and FUM. This study aimed to assess the occurrence and severity of FER, FUM, and corn earworm (Helicoverpa zea Boddie) feeding in Bt ...

CRISPR/Cas: An emerging molecular technology for biological control of fall armyworm
New Plant Protection, Volume 2, Issue 1, March 2025.The application of clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR‐associated (Cas) for controlling agricultural pests, including fall armyworm, is still facing technological, ethical, and biosafety challenges. This review briefly discusses some major challenges and highlights ongoing multidisciplinary progress made to enable ...

Pest Management Science, Volume 80, Issue 6, Page 2796-2803, June 2024.Vip3Aa resistance in all five Helicoverpa zea strains is controlled by a single, recessive and autosomal gene. However, three distinct genetic loci are involved in Vip3Aa resistance in the five strains: one shared by M1‐RR and LT#70‐RR; another shared by R2‐RR and R15‐RR; and a distinct one for AC4‐RR.
