Assessing pest control treatments from phenology models and field data

open access: yesPest Management Science, Volume 81, Issue 4, Page 1851-1859, April 2025.
Theoretical effect of two larvicide sprays, two delayed larvicide sprays that follow an oil treatment, mating disruption, and mating disruption plus four virus sprays on codling moth larva (brown for treated versus pink for untreated) and adult (dark green for treated versus light green for untreated) phenology.

Post-Epidemic Distribution of Schmallenberg Virus in Culicoides Arbovirus Vectors in Poland

open access: yesViruses, 2019
Pooled samples of female and male Culicoides midges (5146 and 332 pools, respectively) that corresponded to a total number of 124,957 specimens were collected between 2013–2017 in the vicinity of cattle barns that were distributed throughout Poland

Intercropping mitigates incidence of the oilseed rape insect pest complex

open access: yesPest Management Science, EarlyView.
Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.

Population dynamics of Coccinella septempunctata (Coleoptera: Coccinellidae) in the region of Edremit Gulf in West Anatolia (Mount Ida)

open access: yesEuropean Journal of Entomology, 2018
This study reports seasonal presence of Coccinella septempunctata L. (Coleoptera: Coccinellidae) in Southeast Turkey, in 2008, 2009 and 2010. Samples were collected from crops in agricultural areas at altitudes of 10 m, 800 m and 1400 m from stands of ...

The overwintering and abundance of cereal aphids

open access: yesAnnals of Applied Biology, 1974
SUMMARYThe longevity of Sitobion avenae varied inversely with temperature from 25 to over 100 days when reared outdoors on barley under lantern jars, being longest between December and April–May. This was due mainly to changes in the length of the pre‐ and post‐reproductive periods rather than the length of the period of reproduction.

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.

Genome-wide analysis of DNA methylation and transcriptional changes associated with overwintering memory in Brassica rapa L. grown in the field

open access: yesChemical and Biological Technologies in Agriculture
Background Winter rapeseed, the sole overwintering oilseed crop in northern China, emphasizes winter resilience, yet epigenetic regulatory mechanisms governing overwintering memory remain poorly understood.

The effects of flooding on survivorship in overwintering larvae of the large copper butterfly Lycaena dispar batavus (Lepidoptera: Lycaenidae), and its possible implications for restoration management

open access: yesEuropean Journal of Entomology, 2003
Previous work suggests that submergence of Lycaena dispar larvae during overwintering may play a significant role in this butterfly's population dynamics. Since potential re-introduction sites in eastern England are prone to regular seasonal flooding, we

Accounting for animal movement during aerial imaging surveys

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Absence of West Nile and Usutu Virus Persistence in Overwintering Mosquitoes in Northeastern France: Insights from Cold-Season Surveillance

open access: yesViruses
Emerging arboviruses of the Orthoflavivirus genus such as West Nile virus (WNV) and Usutu virus (USUV), primarily transmitted by Culex mosquitoes, pose significant public health threats due to their ability to cause severe neurological diseases in humans
