Abstract
The presence, distribution pattern and host preference of the African Invader Fly, Bactrocera invadens (Drew, Tsuruta and White) was studied in three different locations in Akure and its environs, Federal University of Technology Akure (FUTA), Federal College of Agriculture (FECA) and Ipogun (Ondo State, southwestern Nigeria) on mango, citrus and pawpaw for a period of eight weeks. Trapping of the fruit flies was done using fabricated plastic bottle traps baited with Methyl Eugenol (ME) (4-allyl-1,2-dimethoxybenzen) pre-mixed with insecticide, Plan D. The flywas present in the three locations sampled throughout the study period. Average value of the fly obtained revealed that Bactrocera invadens was most abundant at Ipogun village compared with FECA and FUTA and was significantly different at p > 0.05. The result also showed no significant difference in the number of catches at FECA and FUTA, but showed significant difference in Ipogun throughout the period of the study (p > 0.05). Pattern of catches was also observed to increase with the number of weeks on all the hosts at the three locations. The computed mean density of the fly in the various locations showed that number of fly caught was most on the mango host than citrus and pawpaw, though, no significant difference was observed between the three hosts at the end of the eight weeks. This study has provided information on the presence, distribution pattern and preference for already identified hosts within the region. It is therefore recommended that continuous monitoring of the fly’s population be initiated, while the comprehensive control measure is urgently required.

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
