Unusual Life History Characteristics of <I>Elachertus scutellatus</I> Howard (Hymenoptera: Eulophidae), a Koinobionic Ectoparasitoid
Bibliographic record
Abstract
Elachertus scutellatus Howard is a synovigenic, koinobionic ectoparasitoid that preys on the Brazilian skipper caterpillar, Calpodes ethlius (Stoll) (Lepidoptera: Hesperiidae). This wasp exhibits a rare combination of life history strategies, some associated with being a koinobiont and others with being ectoparasitic. The female wasp lays large, inflexible, anhydropic eggs that are passed externally down the ovipositor. This process is uncommon and is considered the morphological intermediate between the use of the ovipositor as an egg-laying device and a stinger. The average clutch size and the oviposition frequency of E. scutellatus females are comparable with other wasps in the Eulophidae. Female wasps were observed to be nonconcurrent host-feeders. The sex ratios of E. scutellatus broods were consistently female biased. Adult male wasps lived longer than female wasps, which may have been a result of host size or the rearing technique used. E. scutellatus has potential as a biocontrol agent because of its female-biased sex ratios, destructive host-feeding, and synovigeny.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
