Validation of a novel bioassay method for the evaluation of the activity of slow‐acting insecticides on tomato borer Phthorimaea absoluta

Pest Management Science, EarlyView.
Extended bioassays revealed that azadirachtin and spirotetramat show strong delayed effects against Phthorimaea absoluta, underestimated by the standard Insecticide Resistance Action Committee (IRAC) method 022 protocol. Incorporating long‐term exposures is essential to accurately assess slow‐acting insecticides and improve resistance management ...

Methomyl resistance in Dalbulus maidis (Hemiptera: Cicadellidae): selection, inheritance and multiple‐resistance

Pest Management Science, EarlyView.
The inheritance of methomyl resistance in Dalbulus maidis is autosomal, incompletely dominant and polygenic. No cross‐resistance was found between methomyl and chlorfenapyr, cyantraniliprole and isocycloseram. Abstract BACKGROUND Acetylcholinesterase (AChE) inhibitor insecticides have been important tools for the management of Dalbulus maidis in Brazil;

Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

Pest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

Inheritance and stability of Cry2Ab2 resistance in an Ostrinia nubilalis strain originating from Wisconsin, U.S.

Pest Management Science, EarlyView.
Resistance to Cry2Ab2 protein in Ostrinia nubilalis is autosomal, functionally recessive, controlled by a single gene, and remains stable over 17 generations in the absence of Cry2Ab2 selection pressure. Abstract BACKGROUND Transgenic corn expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt), including Cry1Ab, Cry1Fa and/or ...

Oral RNAi reduces survival and grain loss in Rhyzopertha dominica, including phosphine‐resistant populations

Pest Management Science, EarlyView.
Oral delivery of dsRNA targeting essential genes reduces adult survival and grain damage in Rhyzopertha dominica, including highly phosphine‐resistant populations. These findings support RNAi as a complementary mode‐of‐action for resistance management and postharvest protection in stored‐grain systems. Abstract BACKGROUND Phosphine fumigation remains a

Diflubenzuron Caused Mitochondrial Dysfunction, Ca2+ Homeostasis Disruption, and Intrinsic Apoptosis in Trophoblastic Cells

Environmental Toxicology, EarlyView.
ABSTRACT Diflubenzuron is used as an insect growth inhibitor, and its potential risk to human health was raised owing to the possibility of environmental residues and human exposure. This study aimed to investigate the toxic mechanism of diflubenzuron on trophoblastic cells such as HTR8/SVneo and JEG‐3 cells. We investigated mitochondrial function, Ca2+

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

Environmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...
