Evolutionary trade-offs of insecticide resistance – the fitness costs associated with target-site mutations in the nAChR of Drosophila melanogaster [PDF]

, 2020
The evolution of resistance to drugs and pesticides poses a major threat to human health and food security. Neonicotinoids are highly effective insecticides used to control agricultural pests.

Cytochrome P450 Herbicide Metabolism as the Main Mechanism of Cross-Resistance to ACCase- and ALS-Inhibitors in Lolium spp. Populations From Argentina: A Molecular Approach in Characterization and Detection

Frontiers in Plant Science, 2020
Knowledge about the mechanisms of herbicide resistance provide valuable insights into evolving weed populations in response to selection pressure and should be used as a basis for designing management strategies for herbicide-resistant weeds.

Point Mutations as Main Resistance Mechanism Together With P450-Based Metabolism Confer Broad Resistance to Different ALS-Inhibiting Herbicides in Glebionis coronaria From Tunisia

Frontiers in Plant Science, 2021
Resistance to acetolactate synthase (ALS) inhibiting herbicides has recently been reported in Glebionis coronaria from wheat fields in northern Tunisia, where the weed is widespread. However, potential resistance mechanisms conferring resistance in these

Contribution of non-target-site resistance in imidazolinone-resistant Imisun sunflower [PDF]

Bragantia, 2017
ABSTRACT The first commercial herbicide-resistant trait in sunflower (Helianthus annuus L.) is known as ‘Imisun’. Imidazolinone resistance in Imisun cultivars has been reported to be genetically controlled by a major gene (known as Imr1 or Ahasl1-1) and modifier genes.

Coexistence of target-site and non-target-site mechanisms of glyphosate resistance in Amaranthus palmeri populations from Argentina

, 2022
. Amaranthus palmeri S. Waston is currently one of the most problematic weeds worldwide. Biotypes with resistance to herbicides such as glyphosate and ALS inhibitors are now present in almost all Argentinian cultivable areas.

A strategy of chemical control of Apera spica-venti L. resistant to sulfonylureas traced on the molecular level

Journal of Plant Protection Research, 2017
Three populations of silky bent grass (Apera spica-venti L.) were tested – one that is susceptible and two that are resistant to sulfonylureas. This study assessed the efficacy of control by different herbicides in a pot experiment and estimated the ...

Asp376Glu Mutation and Enhanced Metabolism Controlling the Resistance to ALS-Inhibiting Herbicides in Ixophorus unisetus (J. Presl) Schltdl. from the Bajio, Mexico

Agronomy, 2023
A study was carried out to determine the ALS (acetolactate synthase)-inhibitor herbicide resistance in the Mexican grass Ixophorus unisetus, a troublesome weed in corn crops in Mexico. First, the resistance was confirmed in field screening assays.

Comparability between insecticide resistance bioassays for mosquito vectors : time to review current methodology? [PDF]

, 2015
Insecticides play an integral role in the control of mosquito-borne diseases. With resistance to insecticides on the rise, surveillance of the target population for optimal choice of insecticides is a necessity.

Long-term trends in Anopheles gambiae insecticide resistance in Côte d'Ivoire [PDF]

, 2014
Malaria control is heavily dependent on the use of insecticides that target adult mosquito vectors via insecticide treated nets (ITNs) or indoor residual spraying (IRS).

Spatial and temporal development of ACCase and ALS resistant Black-grass (Alopecurus myosuroides Huds.) populations in neighboring fields in Germany

Julius-Kühn-Archiv, 2014
The repetitive use of herbicides of a given mode of action as primary tools to control weeds in simplified cropping systems has led to the development of resistant populations.
