Drought Stress Promotes Aphis gossypii Growth but Decreases Host Attractiveness in Melon

Journal of Applied Entomology, EarlyView.
ABSTRACT Drought stress is a significant environmental factor that affects plant physiology and growth, leading to considerable detrimental effects on crop productivity. Cucumis melo, which is widely cultivated for its economic value, is particularly susceptible to water scarcity.

Technology for Intensive Poultry Production as a Source of Odour Emissions with Time-Varying Intensity

Acta Technologica Agriculturae, 2017
The technology for intensive broiler breeding using deep litter method provides convenient conditions for production of odour substances inside the barn. As a consequence, there are relatively high odour emissions in the breeding area and its surrounding,

Aroma-active secondary oxidation products of butter [PDF]

, 2007
Butter contains vitamins, minerals and unsaturated lipids, such as polyunsaturated fatty acids (PUFA) and conjugated linoleic acids (CLAs). However the oxidative stability and consequently the shelf-life of milk products are inversely correlated with ...

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

New Phytologist, EarlyView.
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

Male Psyllids Differentially Learn in the Context of Copulation

Insects, 2017
In the Asian citrus psyllid, Diaphorina citri Kuwayama, stimulatory cuticular hydrocarbons act as sex pheromone attractants. Male psyllids locate aggregations of females using those olfactory cues, as well as vibrational communication on the plant ...
