Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Balancing risk and opportunity: Nasute termite responses to predator and competitor chemical cues

open access: yesEcological Entomology, EarlyView.
Nasutitermes corniger discriminates between heterospecific chemical cues during foraging, showing non‐random resource selection based on predator and competitor information. Predator chemical cues consistently reduce food resource selection, indicating avoidance driven by perceived predation risk rather than direct encounters.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.
