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

open access: yesPest 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 ...

Food preference of Amblyseius swirskii (Acari: Phytoseiidae) on different stages of Tetranychus urticae (Acari: Tetranychidae) and Bemisia tabaci (Hemiptera: Aleyrodidae) 

open access: yesPersian Journal of Acarology, 2016
The prey preference of polyphagous predators plays an important role in suppressing different species of herbivorous mites and insects. Prey stages preference of the predatory mite, Amblyseius swirskii Athias-Henriot was investigated among egg ...

Defensive Nymphs of the Woolly Aphid Thoracaphis kashifolia (Hemiptera) on the Oak Quercus glauca

open access: yesPsyche: A Journal of Entomology, 2016
Aphid nymphs with enlarged fore- and mid-legs were found from woolly colonies of Thoracaphis kashifolia (Hormaphidinae, Nipponaphidini) on leaves of the evergreen Quercus glauca in Japan. It was shown that they grasped an introduced moth larva with their

The continuing significance of chiral agrochemicals

open access: yesPest 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.

The influence of the fasting period on the number of nymphal instars and on the sex ratio of Argas (Persicargas) miniatus (Acari: Argasidae) Influência do período de jejum no número de instares ninfais e na razão sexual de Argas (Persicargas) miniatus (Acari: Argasidae)

open access: yesRevista Brasileira de Parasitologia Veterinária, 2010
The current study investigated the biology of nymphs of the first and second instars of Argas (Persicargas) miniatus. Nymphs were deprived of food for 15, 30 or 60 days and held at 27 ± 1 ºC and 80 ± 10% relative humidity (controlled conditions) or at ...

Natural antibacterial silk produced by feeding silkworms with human hair derived carbon dots

open access: yesResponsive Materials, EarlyView.
Blue‐fluorescent and antibacterial carbon dots, prepared from Crinis Carbonisatus (a traditional Chinese medicine made by calcinating human hair), are fed to silkworms to produce multifunctional silk, which retains its inherent mechanical properties, exhibits blue fluorescence, possesses antibacterial activity, and promotes the wound healing of rats as

Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (
