Contributions of gut bacteria to -induced mortality vary across a range of Lepidoptera [PDF]

, 2015
Background Gut microbiota contribute to the health of their hosts, and alterations in the composition of this microbiota can lead to disease.

Degradation of Cry1Ac Protein Within Transgenic Bacillus thuringiensis Rice Tissues Under Field and Laboratory Conditions [PDF]

, 2017
To clarify the environmental fate of the Cry1Ac protein from Bacillus thuringiensis subsp. kurstaki (Bt) contained in transgenic rice plant stubble after harvest, degradation was monitored under field conditions using an enzyme-linked immunosorbent assay.

Comparative pest management on transgenic (nuopal) and conventional (delta opal) cotton [PDF]

, 2008
A comparison of pest management was drawn between two cotton cultivars, NuOpal (with the cry1Ac gene) and DeltaOpal (nearly isogenic), at the Ceres Consultoria Agronômica's Experimental Field, in Primavera do Leste - Mato Grosso, during the 2007-2008 ...

Transformation of coffee (Coffea Arabica L. cv. Catimor) with the cry1ac gene by biolistic, without the use of markers

Brazilian Journal of Biology
The transformation of coffee plantlets with the cry1ac gene of Bacillus thuringiensis was achieved by biolistic using either the whole pUBC plasmid or only the ubi-cry1ac-nos genetic cassette.

Isolation and characterization of gut bacterial proteases involved in inducing pathogenicity of Bacillus thuringiensis toxin in cotton bollworm, Helicoverpa armigera

Frontiers in Microbiology, 2016
Bacillus thuringiensis (Bt) toxin proteins are deployed in transgenic plants for pest management. The present studies were aimed at characterization of gut bacterial proteases involved in activation of inactive Cry1Ac protoxin (pro-Cry1Ac) to active ...

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.

Non-recessive Bt toxin resistance conferred by an intracellular cadherin mutation in field-selected populations of cotton bollworm.

PLoS ONE, 2012
Transgenic crops producing Bacillus thuringiensis (Bt) toxins have been planted widely to control insect pests, yet evolution of resistance by the pests can reduce the benefits of this approach.

First Record of Helicoverpa armigera (Lepidoptera: Noctuidae) in Argentina [PDF]

, 2014
Debido a la reciente detección de Helicoverpa armigera en Brasil y Paraguay en 2013, se colocaron trampas de feromonas en el cultivo de garbanzo en dos localidades de la provincia de Tucumán para detectar la presencia de este noctuido en Argentina.
