TL;DR: Migratory hoverflies were more likely to occur in restored pastures than nonmigratory Hoverflies, especially in pastures with low connectivity, and among both bumblebees and solitary bees, the occurrence was influenced by nesting traits, with the lowest occurrence of parasitic species and of species digging nests in the ground.

TL;DR: The approach provides an initial theoretical framework to natural enemy use of multiple resources and suggests that primary parasitoid population dynamics are influenced mainly by limitations in reproduction and by the response of parasitoids to separation of floral resources and host patches.

TL;DR: In this paper, the authors used cages covering 4 m² of ground in a long-term agricultural fertilization experiment to investigate whether subsidies targeting the detrital soil mesofauna compartment with organic fertilizers, or the plants with mineral fertilizer, impacted the direction and strength of trophic cascades in an arthropod-plant food web.

TL;DR: In this paper, it is shown that a simplification of the agricultural landscape leads to a decrease in natural enemy activity, reproductive success and abundance, but in general we know little about the processes creating these patterns, and we need more knowledge about the consequences of such changes on the population dynamics of predators and other resident species.

TL;DR: It was impossible, using suction traps, to detect the timing or amount of migration to the peas early in the season, because of the low overall densities of these migrants.
