Abstract

fetched live from OpenAlex

Abstract Sex attractant blends were developed for monitoring three conifer-feeding species of Eucosma Hübner found in pine seed orchards and plantations in Wisconsin and Ontario. Eucosma monitorana Heinrich, which attacks developing cones of red pine, Pinus resinosa Aiton (Pinaceae), preferred lures containing 100:5:15 (μg blend) of ( Z )-9-dodecenyl acetate ( Z 9-12:Ac), ( E )-9-dodecenyl acetate ( E 9-12:Ac), and ( Z )-9-dodecen-1-ol ( Z 9-12:OH), respectively, over lures without the alcohol or with higher levels of E 9-12:Ac. This blend was unattractive to sympatric Eucosma gloriola Heinrich, a species that feeds inside shoots of red pine and eastern white pine, Pinus strobus L. Eucosma gloriola was attracted to a 100:30 blend of Z 9-/ E 9-12:Ac, and adding Z 9-12:OH had no significant effect. Eucosma tocullionana Heinrich, which attacks cones of eastern white pine, was attracted equally to 10:3 and 10:5 μg blends of Z 9-/ E 9-12:Ac, and adding Z9-12:OH had no effect. A ratio as low as 1:0.3 was attractive to E . tocullionana but not to sympatric E . gloriola , which preferred a 100-fold higher dosage of the same blend. The seasonal flight periods of the three species overlapped in all study areas. The flight of E . gloriola usually peaked in late May slightly before that of E . monitorana while the flight of E . tocullionana peaked about 1–3 weeks later. The results indicate that sex pheromones, seasonal flight periods, and host preferences are isolating mechanisms for these closely related sympatric species.

Full frame distilled prediction

Teacher imitation

Not 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.
