Abstract
Abstract Artificial diets are costly to produce, so diet efficiency is critically important to the success of mass rearing insects. One way to improve feed efficiency is through dietary particle size optimization. We tested whether individual crickets ( Gryllodes sigillatus ) reared on diets of different particle sizes (0.088-0.125 mm, 0.5-0.7 mm, and 1.0-1.4 mm) would grow differently. Crickets fed a diet ≥0.5 mm grew heavier during the first three weeks but weighed the same after six weeks regardless of diet size. We also tested for dietary size preference, and given a choice crickets consumed the most feed from the 1.0-1.4 mm diet. Next, we tested whether grinding diet to a powder and also pelleting the powder could influence life history. Powdered diet did not influence growth or development, but crickets fed a 2 mm pelleted diet grew larger body size. Overall, our results demonstrate that diet particle size can be leveraged to enhance cricket life history traits important to mass production, as growth was accelerated on larger particle size diets and crickets preferred to eat larger-sized diets. Researchers focusing on physical properties of insect diets should carefully consider the timing of growth and development milestones through which diet particle size may influence feed efficiency.

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 it
