Field studies of control of <i>Anoplophora glabripennis</i> (Coleoptera: Cerambycidae) using fiber bands containing the entomopathogenic fungi <i>Metarhizium anisopliae</i> and <i>Beauveria brongniartii</i>
Bibliographic record
Abstract
The Asian longhorned beetle, Anoplophora glabripennis, was first found attacking urban street trees in the United States in 1996 and in Canada in 2003. This tree-killing invasive insect has long been a major pest in China and is difficult to control because immature stages live within wood and long-lived adults are often located high in tree canopies. A microbial control product (Biolisa Kamikiri) consisting of non-woven fiber bands impregnated with cultures of an entomopathogenic fungus, Beauveria brongniartii, is marketed in Japan for control of a congeneric orchard pest. Replicated field trials were conducted in Anhui, China to compare Biolisa Kamikiri with similarly prepared bands containing Metarhizium anisopliae for control of A. glabripennis. One fungal band was placed at 2–2.5 m height, around the stem or major scaffold branch on each of 40 willow trees (Salix spp.) per plot, with five plots for each fungal treatment and five control plots. Adult beetles collected from fungal-treated plots 7–22 days after bands were attached to trees died faster than adults from control plots. Beetles exposed to B. brongniartii bands consistently died faster than controls throughout this period, while results from plots with M. anisopliae bands were not as consistent in differing from controls. Numbers of adult beetles from plots of each fungal species dying in <10 days were greater than controls (16% of beetles) but did not differ between fungal treatments (34–35%). Oviposition in fungal-treated plots was approximately half that in control plots. Locations of adult beetles and oviposition scars within tree canopies were quantified to determine optimal locations for band placement. Most adult beetles were found >3.5-m high in trees, with adults in B. brongniartii-treated plots higher within trees than adults in other plots.

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.
