Abstract
A field study was carried out during 2013 at the experimental area of Entomology Section, Agriculture Research Institute, (ARI) Tando Jam to examine the effect of bio-pesticides against sucking insect pests of brinjal crop under field conditions. Five treatments with three replications were applied. The treatments were: T1=chemical control (confidor/Diamond), T2=Neem (Azadirachta indica), T3= Tobacco (Nicotiana tabacum), T4= Eucalyptus (Eucalyptus globus), T5= Untreated (Control). Three insect pests were found infesting brinjal including white flies, jassid and mites. Pre treatment- and post-treatment observations were recorded. The results revealed that against white fly, the first spray of chemical control(confidor) showed highest reduction percent (96.62%) followed by Neem extract (82.60%), Tobacco extract (75.95%), Eucalyptus extract (73.93%) and lowest for untreated control (11.07%); while in the second spray also, chemical control(Diamond) showed highest effect against white fly (78.32%); followed by Neem extract (67.53%), Tobacco extract (56.43%), Eucalyptus extract (42.25%) and least by untreated plot (5.49%). Against jassid, chemical control (confidor) showed highest effect (77.90%) as observed during 1st spray, followed by Neem extract (55.95%), Tobacco extract (53.38%), Eucalyptus extract (53.99%) and untreated control (8.00%), while after second spray also chemical control (Diamond) showed highest reduction percent (81.70%) followed by Neem extract (68.73%), Tobacco extract (55.72%), Eucalyptus extract (50.66%) and the lowest was resulted by untreated control (13.91%). Against mites population on brinjal the first spray results showed that chemical control (confidor) showed highest effect (98.19%) followed by Neem extract (96.19%), Tobacco extract (95.75%), Eucalyptus extract (86.86%) and least population was recorded in untreated control (9.96%). After second spray, chemical control (Diamond) showed highest reduction percent (99.65%), followed by Neem extract (98.33%), Tobacco extract (92.85%), Eucalyptus extract (88.93%) and the lowest reduction percent was resulted by untreated control (9.14%) respectively. Chemical control (confidor/Diamond) showed its superiority in effect to combat sucking insect pests studied in brinjal, followed by Neem extract, Tobacco extract, Eucalyptus extract and untreated control remained the least.

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
