Introduction and establishment of three parasitoids of the lily leaf beetle, lilioceris lilii (coleoptera: chrysomelidae), in north america
Bibliographic record
Abstract
Following three years of discovery and evaluation, three larval parasitoids were imported from Europe and introduced into North America to control Lilioceris lilii (Coleoptera: Chrysomelidae), an introduced herbivore of native and cultivated lilies. The first species, Tetrastichus setifer Thomson (Hymenoptera: Eulophidae), introduced in Massachusetts in 1999, was found to be established in 2002. We made additional releases of T. setifer, introduced the parasitic wasps, Lemophagus errabundus Szepligeti (Hymenoptea: Ichneumonidae) and Diaparsis jucunda (Holmgren) (Hymenoptera: Ichneumonidae), and evaluated the establishment and distribution of the three parasitoids through 2013. Tetrastichus setifer is now established in Massachusetts, Rhode Island, New Hampshire, Maine, Connecticut, and Ontario, Canada. Lemophagus errabundus is established in Massachusetts and Rhode Island, and D. jucunda is established in Massachusetts, Rhode Island, and Maine. All three parasitoids have spread a considerable distance from release sites. The establishment of these parasitoids is associated with substantial reductions of L. lilii populations in some locations. In time it is likely that the parasitoids will spread throughout the North American range of L.lilii, but it may be useful to redistribute the parasitoids to accelerate this process.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
