Maximum foraging ranges in solitary bees: only few individuals have the capability to cover long foraging distances
TLDR
This finding suggests that a close neighbourhood of nesting and foraging habitat within few hundred meters is crucial to maintain populations of these species, and that threshold distances at which half of the population discontinues foraging are a more meaningful parameter for conservation practice than the species specific maximum foraging distances.

The Induction of Volatile Emissions in Maize by Three Herbivore Species with Different Feeding Habits: Possible Consequences for Their Natural Enemies
TLDR
These findings suggest that induction of volatiles is the result of cell tissue damage, particularly to the leaves of the plant, which should have consequences also for the search strategies employed by the natural enemies of the respective herbivores. Expand
Drought changes plant chemistry and causes contrasting responses in lepidopteran herbivores
TLDR
Drought caused plant secondary defense compounds to decrease consistently across all studied plant populations, which evoked contrasting feeding preferences of two herbivore species of the same feeding guild, which suggest herbvore specificity as a possible explanation for herbivor responses to drought. Expand
Quantitative pollen requirements of solitary bees: Implications for bee conservation and the evolution of bee–flower relationships
TLDR
The substantial pollen losses to bees as documented in this study support earlier findings on floral adaptations against excessive pollen harvesting by bees. Expand
Superparasitism in Cotesia glomerata: response of hosts and consequences for parasitoids
TLDR
The response of P.’brassicae larvae to superparasitism and the consequences for the parasitoid were examined in order to elucidate the ecological significance of this behaviour. Expand
Herbivore‐induced emissions of maize volatiles repel the corn leaf aphid, Rhopalosiphum maidis
TLDR
When maize plants are mechanically damaged and the damaged sites are treated with caterpillar regurgitant, the plants will release a specific blend of volatiles that constitute part of the induced plant defence and herbivores will be affected by the odours as well. Expand
Specialized bees fail to develop on non-host pollen: do plants chemically protect their pollen?
TLDR
The results strongly suggest that pollen of these four taxonomic groups possess protective properties that hamper digestion and thus challenge the general view of pollen as an easy-to-use protein source for flower visitors. Expand
Control potential of three hymenopteran parasitoid species against the bean weevil in stored beans: the effect of adult parasitoid nutrition on longevity and progeny production
TLDR
D. basalis produced the highest number of progeny and had the longest reproductive lifetime, making it the most promising parasitoid for the control of A. obtectus, and H. prosopidis had a shorter oviposition period than D.basalis, resulting in a lower lifetime progeny production. Expand
Stress magnitude matters: different intensities of pulsed water stress produce non‐monotonic resistance responses of host plants to insect herbivores
TLDR
Water stress may increase or reduce the suitability of plants for herbivores and consideration of stress phenology (pulsed vs. continuous stress) to explain these conflicting effects of plant water stress on herbivore performance. Expand
Long flights in Cydia pomonella L. (Lepidoptera: Tortricidae) measured by a flight mill: influence of sex, mated status and age
TLDR
It is concluded that males and females have little or no difference in flight capacity and that both the within‐and between‐habitat flights are similar in number and magnitude for both sexes. Expand
