Toxicity of Rhododendron anthopogonoides Essential Oil and Its Constituent Compounds towards Sitophilus zeamais

open access: yesMolecules, 2011
The screening of several Chinese medicinal plants for insecticidal principles showed that essential oil of Rhododendron anthopogonoides flowering aerial parts possessed significant toxicity against maize weevils, Sitophilus zeamais.

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

open access: yesArchaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

open access: yesBoreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Effect of Environmental Conditions on the Permeability of High Density Polyethylene Film To Fumigant Vapors

open access: yes, 2016
Soil fumigation in greenhouses or agricultural fields often includes tarping the soil surface with polyethylene (PE) films to contain the fumigant in the soil and reduce emissions to the atmosphere.

Assessing the Efficacy of Steinernema carpocapsae for Biological Control of Megaselia halterata on Mushroom Farms

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Steinernema carpocapsae applications averaged 40%–60% mortality of mushroom phorid larvae in laboratory experiments. Survival experiments showed that nematode populations drop 50% approximately 5 days post application in mushroom compost. ABSTRACT Mushroom phorid flies (Megaselia halterata; MPF) are a major pest of commercial mushroom production, where

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.
