Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Do turning biases by the 7-spot ladybird, Coccinella septempunctata, increase their foraging efficiency?

, 2007
The hypothesis that foraging male and female Coccinella septempunctata L. would exhibit a turning bias when walking along a branched linear wire in a Y-maze was tested. Individuals were placed repeatedly in the maze.

Assessing Biodiversity in Agricultural Landscapes Through Drone‐Based Environmental DNA Sampling

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We developed a drone‐based environmental DNA (eDNA) swabbing method to assess hexapod diversity in agricultural fields under three management types (conventional, organic, and IP‐Suisse), detecting 75 taxa across 19 families. eDNA replicates showed consistent within‐field results, though no significant differences in diversity were found between ...

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, Volume 82, Issue 8, Page 7903-7914, August 2026.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

The influence of tolfenpyrad on fitness, development, and reproduction in parents and offspring of Coccinella septempunctata

Ecotoxicology and Environmental Safety, 2021
Coccinella septempunctata (ladybird) is one of the foremost natural predators that feed on aphids. Thus, C. septempunctata serves as an effective biological control agent in integrated pest management (IPM) programs. To supplement the activity of biological control agents, IPM programs often incorporate chemical pesticides to bolster crop protection ...
