The thermal constant of the onchocerciasis vector <i>Simulium damnosum</i> s.l. in West Africa
Bibliographic record
Abstract
The minimum water temperature for development (t(0)) and the thermal constant (K) for the development of immature stages of Simulium damnosum s.l. (Diptera: Simuliidae) in West Africa were estimated as 20.1 °C and 93 day-degrees, respectively, based on analyses of published data on development rates of eggs, larvae and pupae at different water temperatures (24.0 °C and 31.5 °C). Thus, at a constant water temperature of 30.0 °C (approximately 10 °C above t(0)), adult flies would emerge about 9 days after oviposition. Analysis of a dataset probably restricted to S. damnosum s.s., but for which the temperature for the egg stage varied, revealed a much lower t(0) (16.3 °C) and a much higher K (181 day-degrees), suggesting that the insects' thermal relations may be cytoform-specific. The results will aid control decisions and predictions of possible effects of climate change on sizes and geographic distributions of populations of onchocerciasis vectors in West Africa.

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.
