Density‐dependent and density‐independent responses of three species of <i>Telenomus</i> parasitoids of hemlock looper eggs
Bibliographic record
Abstract
Abstract We examined patterns of host exploitation by natural populations of three Telenomus species (Hymenoptera: Scelionidae) parasitizing hemlock looper, Lambdina fiscellaria Guenée (Lepidoptera: Geometridae), eggs in sentinel traps in eastern Quebec and western Newfoundland (Canada). The percentage of eggs parasitized by Telenomus flavotibiae Pelletier and Telenomus coloradensis Crawford in autumn, and by Telenomus droozi Muesebeck in spring either were not or only weakly related to host egg density. In contrast, the percentage of eggs parasitized by T . coloradensis in the spring was positively related to host egg density. Telenomus flavotibiae and T . droozi parasitized eggs in fewer traps than T . coloradensis , suggesting that they were less abundant or less efficient locating host patches. Eggs parasitized by T . droozi only occurred in traps with eggs parasitized by T . coloradensis , suggesting that it may be responding to kairomones emitted by T . coloradensis . In contrast, neither the number nor sex ratio of T . coloradensis emerging from eggs in traps with T . droozi differed from those in traps without this congeneric. Secondary sex ratios of all three species were significantly female biased. Our study suggests that only T . coloradensis has the potential to regulate hemlock looper populations.

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.
