Species-dependent captures of three <i>Limonius</i> pest click beetle (Coleoptera: Elateridae) species in western North America with aerial and ground traps
Bibliographic record
Abstract
In western North America, 3 pest wireworms in the genus Limonius co-occur on farmland, and the click beetle adult males respond to the same single-component sex attractant, limoniic acid. While divergence in seasonal occurrence may provide a means of separating sexual communication for Limonius canus (LeConte) and Limonius californicus (Mann.), both species overlap temporally with Limonius infuscatus (Mots.), suggesting the existence of additional reproductive isolating mechanisms. To determine the effect of trap height on the relative captures of these species, we deployed ground-based Vernon Pitfall Traps and aerially suspended Japanese Beetle traps baited with limoniic acid dispensed from rubber septa or plastic capsules, in British Columbia, Alberta, Washington state, and Montana. The proportion collected of each species differed among study locations, but our data indicate species differ in trap preference, with L. infuscatus and L. californicus preferring ground traps, and L. canus preferring aerial traps. This possibly reflects preferences in where species locate mates, and therefore another separation mechanism. Lure type also had a significant effect on captures in most studies, with generally more L. californicus and/or L. infuscatus collected if capsule dispensers, and more L. canus if septa dispensers were used. Implications for monitoring these species with these trap and dispenser combinations are discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
