Abstract
The functional and numerical responses of the predatory mite Neoseiulus californicus (McGregor) (Phytoseiidae) females reared on thorn apple pollen (Datura stramonium L.) over 40 generations on different densities (2, 4, 8, 16, 32, 64 and 128) of deutonymphs of Tetranychus urticae Koch (Trombidiformes: Tetranychidae) were determined. The results indicated a type II functional response for N. californicus on T. urticae in generations of G0 (no rearing on pollen as control), G10, G20, G30, and G40. The attack rate (α) for N. californicus females increased as the number of generations increased from G0 (0.079 h<sup>-1</sup>) to G20 (0.182 h<sup>-1</sup>), then decreased in G30 and G40. The longest and shortest handling time (T<sub>h</sub>) was observed in G0 (1.670 h) and G40 (0.890 h), respectively. The highest value of maximum attack rate (T/T<sub>h</sub>) was estimated in G40 (26.96 prey/day). The equation of the regression line showed that the relationship between the prey density and the number of eggs laid was significant in G0, G10 and G40, and the number of eggs deposited by N. californicus increased with increasing the density of prey. The relationship between the prey density and ECI (the efficiency of conversion of ingested food) was not significant in tested generations. Our findings show that long-term rearing on thorn apple pollen did not affect the type of functional response and efficiency of N. californicus by confirming this predator is an effective biological control agent against T. urticae.

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
