Colony Size, Rather Than Geographic Origin of Stocks, Predicts Overwintering Success in Honey Bees (Hymenoptera: Apidae) in the Northeastern United States

open access: yesJournal of Economic Entomology, 2018
Honey bees (Apis mellifera L.) are key pollinators of agricultural crops. However, approximately 30% of managed colonies die each winter in the United States.

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.

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.

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.

Mating Status Influences Cold Tolerance and Subsequent Reproduction in the Invasive Ladybird Harmonia axyridis

open access: yesFrontiers in Ecology and Evolution, 2017
Among arthropods, ability to survive cold conditions may be instrumental for species invading temperate or colder climatic zones. Cold tolerance can be influenced by multiple environmental and physiological factors.

Experiences with entomopathogenic nematodes for the control of overwintering codling moth larvae in Germany [PDF]

open access: yes, 2008
Entomopathogenic nematodes were tested for their potential as tool in resistance management of codling moth Cydia pomonella L. in organic fruit growing. In two field tests, the adults emerging from stems treated with nematodes were monitored.

Further Observations on the Nesting Behavior of \u3ci\u3eLiris Argentatus\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
A three-celled nest of Liris argentatus was excavated and examined in upstate New York. The nest was constructed from the terminus of an abandoned cicada-killer burrow and the cells contained 1-4 incompletely paralyzed Gryllus pennsylvanicus as prey. Two

Predicting Overwintering of Wheat Stripe Rust in Central and Northwestern China.

open access: yesPlant Disease, 2019
Stripe rust, caused by Puccinia striiformis Westend. f. sp. tritici Erikss. (Pst), is an important disease of wheat. In China, Pst management has focused on the Gansu region where the pathogen can complete its annual cycle, including oversummering and ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

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
