Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps
Urbanisation can negatively affect cavity‐nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2‐year experiment across urban allotments spanning an urbanisation gradient, we found no effect of added floral resources on nest uptake, while hymenopteran abundance ...

European corn borer (Ostrinia nubilalis) (ECB) is an important maize pest in central and northern Europe. Presently it is controlled by insecticides or biological agents such as Trichogramma brassicae in several European countries, excluding Slovenia ...

Arthropods Associated With Purple Loosestrife in Illinois Wetlands [PDF]
We estimated and described the arthropod fauna on purple loosestrife (Lythrum salicaria) plants in northeastern Illinois wetlands. A total of 1063 individual arthropods were collected—930 insects and 133 arachnids.

We compared the community structure of Aculeata bees and wasps in natural deciduous broadleaved forests and two coniferous plantations (Cryptomeria japonica, “Sugi” and Chamaecyparis obtusa, “Hinoki”) in southern Kyushu, Japan. Compared with natural forests, the dependence of Aculeata communities on the detritus‐based food chain increased in both ...

Study on Diplazontinae (Hymenoptera: Ichneumonidae) in north central Iran
The fauna of the subfamily Diplazontinae (Hymenoptera: Ichneumonidae) in the north central parts of Iran was studied during 2010-2011. A total of 933 specimens were collected in 30 localities at different altitudes using Malaise traps.

Effects of landscape context on herbivory and parasitism at different spatial scales [PDF]
Local community structure and interactions have been shown to depend partly on landscape context. In this paper we tested the hypothesis that the spatial scale experienced by an organism depends on its trophic level.

Using extensive Malaise trapping, we collected a high richness of Pimplinae (86 species, 5892 individuals) in habitat types across a successional gradient. We found higher richness in forest than in nearby farmland, highlighting the importance of tropical forest in conserving parasitoid wasp richness.
