Abstract
Background: Rhynchophorus phoenicis is arguably one of the most sought-after edible insects in the tropics. It is widely distributed in Africa and is a major pest of palm trees in Africa, Southern Asia, and South America. Globally, the population has been predicted to surpass 9 billion by 2050, leading to food insecurity. Objective: This research investigated rearing the edible insect (Rhynchophorus phoenicis) in different substrates under laboratory conditions to address problems associated with the weevils' availability for solving malnutrition issues in children when consumed. Methods: Ten (10) adult palm weevils were reared in different substrates (coconut husk, sugarcane, pawpaw, and a combination of all the substrates) under laboratory conditions with palm fiber as the control and arranged in triplicates to assess their emergence and survival. Data on larvae emergence, survival, and pupation were obtained within four (4) to eight (8) weeks post-emergence. Results: The rearing experiments showed that larvae emergence and survival (184.08±19.7), pupation rate (53.25±7.0), and adult emergence (12.92±1.8) were highest in coconut husk and least in pawpaw substrate. There was also a significant difference between the larvae emergence and survival, pupation, and adult emergence in the various substrates compared to the control (p<0.05). Implication: The study demonstrated the feasibility of mass-rearing African palm weevil (Rhynchophorus phoenicis) larvae, which, if incorporated into children's diets, will be immensely significant in solving nutritional deficiencies and problems associated with malnutrition.

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
