Immature development and adult longevity of the soybean tentiform leafminer (Lepidoptera: Gracillariidae)
Bibliographic record
Abstract
The leaf-mining microlepidopteran, Macrosaccus morrisella (Fitch) (Lepidoptera: Gracillariidae), has emerged as a new pest of soybean, Glycine max (L.) Merrill (Fabales: Fabaceae), in Canada and the United States, but little is known about its life history traits. Thus, this study was conducted to assess the immature developmental rate of M. morrisella, from egg to adult emergence, on soybean at different temperatures, and the longevity of adults supplied with water and/or honey at different temperatures. The time to 50% emergence of adults was 71.90, 36.33, 24.62, and 17.83 days at 15, 20, 25, and 30 °C, respectively. The lower developmental threshold of M. morrisella was estimated at 8.96 °C, with 425.04 degree-days required for egg-to-adult development. For adult longevity, time to 50% mortality at 25 °C was 15.00, 4.00, and 2.00 days when adults were provided with 25% (v/v) honey-water solution, water, or nothing, respectively. In a follow-up experiment, time to 50% mortality at 25 °C was 24.00, 6.00, 3.00, and 3.00 days when adults were provided with honey and water (offered separately), honey, water, or nothing, respectively, with a synergistic effect when honey and water were offered simultaneously as opposed to honey or water alone. Finally, when fed 25% (v/v) honey-water solution and maintained at 20, 25, and 30 °C, time to 50% mortality of adults was 26.50, 15.00, and 15.00 days. These results inform the understanding of the basic biology of M. morrisella and will help inform the future development of management programs for this insect in soybean.

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.
