OVIPOSITION BEHAVIOUR OF APHIDIINE WASPS (HYMENOPTERA: BRACONIDAE, APHIDIINAE): MORPHOLOGICAL ADAPTATIONS AND EVOLUTIONARY TRENDS
Bibliographic record
Abstract
Abstract We examined oviposition behaviour in 49 species representing 19 genera of Aphidiinae. All species are solitary parasitoids of aphids (Hemiptera: Aphidoidea). Six general types are described that differ in oviposition time, behaviour, and morphology. The Ephedrini have the least specialized oviposition behaviour within the subfamily, with Praini and Aphidiini displaying various adaptations for host capture and oviposition. Use of the forelegs to grasp and orient aphids for oviposition has arisen twice, in Praini and, independently, in the genus Monoctonus Haliday (Aphidiini: Monoctonina). Morphological modifications of the terminal abdominal segments for host capture are found in Trioxina and in several species of Pauesia Quilis (Aphidiina). A “quick” sting is characteristic of species in the genus Aphidius Nees and related genera. The greatest degree of behavioural diversification occurred among Pauesia species, including cryptic behaviour, ant mimicry, and “sneak” oviposition. Acquired chemical camouflage and mimicry of the host’s cuticular hydrocarbon pattern to avoid detection by guarding ants is found in Aclitus obscuripennis Foerster, the genus Paralipsis Foerster, and the two closely related genera Adialytus Foerster and Lysiphlebus Foerster. It is suggested that the main driving forces in the evolution of parasitoid oviposition behaviour were aphid defensive behaviour and avoidance of aggression by trophobiotic ants. The results are compared with phylogenetic relationships inferred from morphological and molecular data.

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.
