Factors Influencing the Use of Trap Plants for the Control of <I>Frankliniella occidentalis</I> (Thysanoptera: Thripidae) on Greenhouse Potted Chrysanthemum
Bibliographic record
Abstract
Abstract Western flower thrips (Frankliniella occidentalis (Pergande), Thysanoptera: Thripidae) are a major pest of greenhouse ornamentals. Insecticides are the main control measure used for F. occidentalis on ornamentals and impede the use of biological control in the greenhouse. Flowering chrysanthemums, Dendranthema grandiflora (Tzvelev), could be used as trap plants (i.e., plants that are more attractive to a pest than the crop) in an integrated pest management (IPM) program for the control of F. occidentalis on potted chrysanthemum in greenhouses. This study focused on certain behavioral characteristics of F. occidentalis that can influence the efficiency of the trap plant strategy. First, host plant selection of adult F. occidentalis was studied by determining the influence of distance and stage of the crop on the attractiveness of flowering chrysanthemum as trap plants. Second, the influence of F. occidentalis colonization (resident versus dispersing F. occidentalis) on trap plant efficacy was determined. Flowering chrysanthemum plants were more attractive to adult F. occidentalis than the vegetative, bud, and crack-bud plant stages up to distances of 12 m, and trap plants were more effective at attracting dispersing F. occidentalis than resident F. occidentalis. It is concluded that flowering chrysanthemums have potential as trap plants for F. occidentalis in potted chrysanthemum before flowering.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
