Collection and Laboratory Culture of Ormia ochracea (Diptera: Tachinidae)
Bibliographic record
Abstract
The Family Tachinidae is one of the most speciose families in the Order Diptera with approximately 1300 species occurring in North America alone. Research on the species Ormia ochracea (Bigot) (Diptera: Tachinidae) has largely focused on the problems incurred by their hosts as a result of parasitism or on the mechanics of their hearing. Little research effort has been devoted to the behavior or life history of these flies. Part of the reason they have remained lightly researched is the difficultly in maintaining a laboratory culture. Herein, we provide a detailed guide to collecting O. ochracea in the field, culturing them in the laboratory, and maintaining stock populations for multiple generations. We also provide data on the effectiveness of capturing O. ochracea in wooded versus open field areas, as well as data on the effectiveness of manually parasitizing crickets with O. ochracea larvae to propagate stock fly populations in the laboratory. Our results suggest that during field collection, traps should broadcast calls in wooded areas; and that manual parasitization is an effective way of culturing small colonies of O. ochracea in the laboratory.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
