Mortality in an invasive ant does not scale linearly with fipronil exposure

Pest Management Science, EarlyView.
Increasing fipronil concentration did not linearly increase yellow crazy ant mortality when introduced via horizontal transfer; high doses may limit food sharing. Queen mortality was low, and surviving workers were averse to feeding. Abstract Background Controlling eusocial invasive and other pestiferous insects is difficult.

Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

Pest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

Toxicity, Repellency, and Horizontal Transfer of Foam Insecticides for Remedial Control of an Invasive Drywood Termite, Cryptotermes brevis (Blattodea: Kalotermitidae)

BioResources, 2023
Laboratory tests were conducted to compare imidacloprid and fipronil foams against various criteria to determine the effect of the deposit conditions, exposure method, and exposure time on the toxicity, repellency, and horizontal transfer of selected ...

Rapid evolution and genetic basis of spinetoram resistance in Phthorimaea absoluta: evidence from six years of monitoring and laboratory selection

Pest Management Science, EarlyView.
Resistance to spinetoram in Phthorimaea absoluta is rapidly selected and functionally recessive at field‐relevant concentrations. Metabolic detoxification contributes partially, while cross‐resistance to spinosad and increased susceptibility to diamides and isoxazolines highlight practical options for resistance monitoring and insecticide rotation ...

Label-Free Aptasensor for Detection of Fipronil Based on Black Phosphorus Nanosheets

Biosensors, 2022
A label-free fipronil aptasensor was built based on Polylysine-black phosphorus nanosheets composition (PLL-BPNSs) and Au nanoparticles (AuNPs). A PLL-BP modified glassy carbon electrode (GCE) was fabricated by combining BP NSs and PLL, which included a ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Route‐Dependent Toxicity and Ecological Selectivity of Melaleuca alternifolia Essential Oil in Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...

Commercial Product Based on Metarhizium Anisopliae Affects Survival, Midgut Morphology, and Behavior in the Stingless Bee Scaptotrigona depilis (Hymenoptera: Apidae)

Environmental Toxicology, EarlyView.
ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.
