Potential of Nabis americoferus and Orius insidiosus as biological control agents of Lygus lineolaris in strawberries.
Bibliographic record
Abstract
The tarnished plant bug, <em>Lygus lineolaris,</em> is a major strawberry pest. Only marginally effective control methods exist to manage this pest. Various predators attack <em>L. lineolaris</em>, but their potential is overlooked. In this study, we explore the potential of two omnivorous predators of the tarnished plant bug: the damsel bug, <em>Nabis americoferus,</em> and the minute pirate bug, <em>Orius insidiosus</em>. Firstly, the predation rate of these predators was measured in laboratory tests. Secondly, their potential release rates and release periods were determined in the field. Results show that <em>N. americoferus</em> feeds on all nymphal stages and adults of the tarnished plant bug, while <em>O. insidiosus</em> attacks only smaller nymphs. In the field, all tested densities of <em>N. americoferus</em> (0.25, 0.5, and 0.75 individual/ plant) reduced the population of tarnished plant bugs for several weeks compared to the control treatment, but the effect of <em>O. insidiosus </em>alone was marginal. Additionally, for all release periods tested, <em>Nabis americoferus</em> was efficient in reducing the pest population. These results demonstrate the potential of <em>N. americoferus</em> to control the tarnished plant bug in strawberry fields. We discuss the possible application of these results for the establishment of an effective and economically viable biological control strategy.

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.
