Amendment of Potting Soil With Black Soldier Fly Byproducts Affects Fungus Gnat Development

Entomologia Experimentalis et Applicata, EarlyView.
The study's three experiments were conducted in accordance with the development stages of fungus gnats, with adults emerging from the four treatment substrates and being caught on sticky cards as a common indicator. The treatments were formed from peat‐free potting soil, either pure or supplemented with combinations of byproducts from black soldier fly

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

The slow emergence of the rational investor: Grain markets and grain storage of rural estates in western Germany, eighteenth and early nineteenth centuries

The Economic History Review, EarlyView.
Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...
