Efficacy of Selected Commercial Bio‐Products in Disrupting Symbiont Acquisition and Survival of Halyomorpha halys (Hemiptera: Pentatomidae)

Entomologia Experimentalis et Applicata, EarlyView.
Targeting the symbiont Candidatus Pantoea carbekii offers a novel way to manage the invasive brown marmorated stink bug (Halyomorpha halys). Among the three commercial bio‐products tested, Dentamet significantly reduced symbiont acquisition and caused up to 75% nymphal mortality in laboratory conditions, which was confirmed by quantitative Real‐Time ...

Quantifying Species‐ and Community‐Level Predation by Carabids on Pests and Beneficials in Wheat and Beet Fields

Entomologia Experimentalis et Applicata, EarlyView.
Using a model that translates qualitative prey detection data (presence/absence in predator gut contents) into quantitative predation rates, we estimate species‐specific diets of nine carabid species across three cropping contexts (wheat, sugar beet, and fodder beet) for five prey types.

Ecosystem Services Against Illegal Immigration: The Natural Control of the Migratory Butterfly Painted Lady (Vanessa cardui) by Cotesia vestalis (Hymenoptera, Braconidae) on Organic Soybean in Ukraine

Entomologia Experimentalis et Applicata, EarlyView.
In central Ukraine, the migratory butterfly Vanessa cardui emerged as a key pest of organic soybean during its outbreaks in 2019 and 2022. Despite early defoliation, crops recovered strongly due to high parasitism by Cotesia vestalis, reaching 100% in some fields.

Pharmacophore of neonicotinoid insecticides

Journal of Pesticide Science, 2008
Our recent study related to neonicotinoid pharmacophore was presented. The first topic described on the QSAR study with 17 variants of 2-nitroiminoimizolidine. The insect neuroblocking potency is proportionally related both to the Mulliken charge on the nitro oxygen atom and log P.

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

Journal of Applied Entomology, EarlyView.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.
