Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

Development of Bacillus thuringiensis CryIC resistance by Spodoptera exigua (Huebner) (Lepidoptera : Noctuidae) [PDF]

open access: yes, 1995
Selection of resistance in Spodoptera exigua (Hubner) to an HD-1 spore-crystal mixture, CryIC (HD-133) inclusion bodies, and trypsinized toxin from Bacillus thuringiensis' subsp, aizawai and B. thuringiensis subsp.

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Environmental risk assessment of genetically modified plants - concepts and controversies [PDF]

open access: yes, 2011
Background and purpose: In Europe, the EU Directive 2001/18/EC lays out the main provisions of environmental risk assessment (ERA) of genetically modified (GM) organisms that are interpreted very differently by different stakeholders. The purpose of this

Three Decades of China's Bt Cotton: Achievements and Insights

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.

Bacillus thuringiensismembrane-damaging toxins acting on mammalian cells [PDF]

open access: yesFEMS Microbiology Letters, 2014
Bacillus thuringiensis is widely used as a biopesticide in forestry and agriculture, being able to produce potent species-specific insecticidal toxins and considered nonpathogenic to other animals. More recently, however, repeated observations are documenting the association of this microorganism with various infectious diseases in humans, such as food-

Poultry and Beef Meat as Potential Seedbeds for Antimicrobial Resistant Enterotoxigenic Bacillus Species: A Materializing Epidemiological and Potential Severe Health Hazard [PDF]

open access: yes, 2018
Although Bacillus cereus is of particular concern in food safety and public health, the role of other Bacillus species was overlooked. Therefore, we investigated the presence of eight enterotoxigenic genes, a hemolytic gene and phenotypic antibiotic ...

A natural hybrid of a Bacillus thuringiensis Cry2A toxin implicates Domain I in specificity determination [PDF]

open access: yes, 2017
A PCR-RFLP method was used to identify cry2A toxin genes in a collection of 300 strains of Bacillus thuringiensis. From 81 genes identified, the vast majority appeared to be cry2Aa or cry2Ab, however three showed a different pattern and were subsequently

Ectopic Expression of ScALDH21 From a Desert Moss Enhances Cotton Resistance to Verticillium Wilt via the Modulation of Jasmonates and Phenylpropanoid Pathways

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Biotic stresses, particularly Verticillium wilt (VW), lead to a global decline in cotton yields. Here, we demonstrate that ectopic expression of ScALDH21, a gene from the desiccation‐tolerant moss Syntrichia caninervis Mitt. and absent in angiosperms, enhances cotton's resistance to VW.

Parallel Evolution of Bacillus thuringiensis Toxin Resistance in Lepidoptera [PDF]

open access: yesGenetics, 2011
Abstract Despite the prominent and worldwide use of Bacillus thuringiensis (Bt) insecticidal toxins in agriculture, knowledge of the mechanism by which they kill pests remains incomplete. Here we report genetic mapping of a membrane transporter (ABCC2) to a locus controlling Bt Cry1Ac toxin resistance in two lepidopterans, implying that ...
