Annals of Applied Biology, EarlyView.This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

Agricultural and Forest Entomology, EarlyView.Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

The Auditory System of the Dipteran Parasitoid Emblemasoma auditrix (Sarcophagidae) [PDF]
, 2016 Several taxa of insects evolved a tympanate ear at different body positions, whereby the ear is composed of common parts: a scolopidial sense organ, a tracheal air space, and a tympanal membrane. Here, we analyzed the anatomy and physiology of the ear at

Orchard Management Influences Predation of Halyomorpha halys Eggs
Entomologia Experimentalis et Applicata, EarlyView.We investigated predation of eggs of the invasive stink bug Halyomorpha halys on apple trees in conventional, organic, and extensively managed Dutch orchards. Predation exceeded 40% in extensively managed orchards but was only about 10% in conventional and organic ones. We used camera traps to reveal natural enemies that may contribute to H.

Ecological Entomology, EarlyView.We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...
