Synergism of the Bacillus thuringiensis Cry1, Cry2, and Vip3 Proteins in Spodoptera frugiperda Control
(2019-07-15)
The polyphagous caterpillar, Spodoptera frugiperda, has been controlled with either chemical insecticides or transgenic plants such as Bt maize that expresses the cry and/or vip genes of the Bacillus thuringiensis (Bt) ...
cry1 genes from Bacillus thuringiensis: specificity determination and implications for primer design
(Springer, 2009-12-01)
Some pest management programs employ PCR to identify cry1 genes from Bacillus thuringiensis to predict bacterial toxicity towards different insect pests. However, due to changes on the mode of action of the Cry proteins, ...

Mechanism of action of Cry1ac toxin from Bacillus thuringiensis in Helicoverpa armigera (Lepidoptera: Noctuidae)
(Universidade Estadual Paulista (Unesp), 2021-04-09)
- Helicoverpa armigera (Hübner, 1805) (Lepidoptera: Noctuidae), known as Cotton bollworm is an insect pest of global importance in cotton crop. Nonetheless, it also attacks several other important economic crops worldwide, ...
Effect of the Cry1, Cry2 and Vip3 protein combinations on the control of Anticarsia gemmatalis (Erebidae) and Chrysodeixis includens (Noctuidae) Lepidoptera
(2020-01-01)
The transgenic soybean expressing the cry1Ac insecticidal gene of the Bacillus thuringiensis bacterium has been widely adopted in agriculture. This bacterium acts as an efficient control agent of pest insects due to the ...
Diversity and distribution of lepidoptera-specific toxin genes in Bacillus thuringiensis strains from Argentina
(2017-05)
A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cry1, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific ...
Sobrevivência e desenvolvimento de espécies de Spodoptera (Lepidoptera: noctuidae) em soja expressando Cry1Ac e Cry1F e implicações no manejo da resistência
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2020-02-07)
Species of the genus Spodoptera have caused significant damage to soybean, Glycine max (L.) Merril in Brazil. Among these species, stand out Spodoptera frugiperda (Smith, 1797), Spodoptera eridania (Stoll, 1782), Spodoptera ...
