Biologically active cuticular compounds of female <i>Sirex noctilio</i>
Bibliographic record
Abstract
Abstract The Eurasian woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae) is a major invasive pest in pine plantations of the Southern Hemisphere. In this study, we aimed to identify pheromone compounds in S. noctilio females, for potential use in lures for pest monitoring and control. An examination of S. noctilio body washes resulted in the identification of a behaviorally active compound, 10‐oxo‐decanoic acid (10‐ODA), that is derived from cuticular hydrocarbons of females. This oxocarboxylic acid is likely produced through oxidative reactions at the cleavage of double bonds of certain female‐produced cuticular dienes. Gas chromatography‐electroantennogram detection (GC‐EAD) analyses showed that only male antennae consistently responded to natural and synthetic 10‐ODA. In olfactometer assays, 10‐ODA alone was attractive to S. noctilio males, although males marginally preferred the combination of 10‐ODA and nonanal, compared with 10‐ODA alone. This suggests pheromonal activity of this compound. However, no wasps were captured in initial field trapping experiments with 10‐ODA and further work is required.

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.
