MogR Is a Ubiquitous Transcriptional Repressor Affecting Motility, Biofilm Formation and Virulence in Bacillus thuringiensis

Frontiers in Microbiology, 2020
Flagellar motility is considered an important virulence factor in different pathogenic bacteria. In Listeria monocytogenes the transcriptional repressor MogR regulates motility in a temperature-dependent manner, directly repressing flagellar- and ...

New resistance mechanism in Helicoverpa armigera threatens transgenic crops expressing Bacillus thuringiensis Cry1Ac toxin [PDF]

, 2005
In Australia, the cotton bollworm, Helicoverpa armigera , has a long history of resistance to conventional insecticides. Transgenic cotton (expressing the Bacillus thuringiensis toxin Cry1Ac) has been grown

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

Pest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Potential applications of Agrobacterium virulence gene promoters in plant-protecting microbial inoculants [PDF]

, 1994
The concept behind this project was to continue the development of strains of Agrobacterium tumefaciens that were capable of producing pesticidal proteins in response to plant wounding, thereby killing the invading organism.

Impacts of a Sweet Orange Essential Oil–Based Biopesticide on Exorista larvarum, a Parasitoid Tachinid Fly With a Dual Role

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 933-941, August 2026.
Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.
