An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

open access: yesPest Management Science, EarlyView.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Field size as a determinant of common vole population density

open access: yesPest Management Science, EarlyView.
Population densities of the common vole, an agricultural pest, increase nonlinearly with forage field size, especially in fields below 20 ha. Reducing the field size may help limit crop damage in farmland. Abstract BACKGROUND Environmental heterogeneity in agricultural landscapes is a key driver of biodiversity and ecological processes, yet its role in

Chemical Weed Control in Container-grown Nursery Stock1

open access: yesHortScience, 1973
Abstract Broad-spectrum herbicides severly injured container-grown (Cotoneaster divaricata, Rehd. & Wils. and Euonymus fortunei, (Turcz.) Hand-Mazz. cv. Coloratus, because of rapid leaching into the root zone as a result of the porous peat-perlite medium. Injury was eliminated when activated carbon at 0.75 kg/m3 was mixed into the medium.
