Feeding, Development, and Oviposition of Bertha Armyworm (Lepidoptera: Noctuidae) on Different Host Plant Species
Bibliographic record
Abstract
Survival, development, and oviposition of the polyphagous insect Mamestra configurata Walker (Lepidoptera: Noctuidae) were compared on different host plant species of the families Brassicaceae [Brassica rapa L., Brassica napus L., Brassica juncea (L.) Cosson, Sinapis alba L., and Thlaspi arvense L.], Compositae [Cirsium arvense (L.) Scop.], Leguminosae (Pisum sativum L. and Medicago sativa L.), Linaceae (Linum usitatissimum L.), and Chenopodiaceae (Chenopodium album L.). Larvae developed faster on intact host plant tissue of all species than they did on excised leaf tissue. First instars of M. configurata did not survive on leaves of T. arvense. Although 97% of larvae survived to the sixth instar on M. sativa, complete mortality was observed on this host plant before pupation. On the other host plants studied, survival rates to sixth instar and pupation were similar. C. album was significantly more preferred than all other species in larval feeding choice experiments, whereas B. juncea and M. sativa were significantly less preferred than the other species. Pupal weights were highest on C. album and S. alba and were lowest on P. sativum and B. juncea. Larval development was most rapid on C. album and was slowest on B. juncea. C. album was significantly more preferred for oviposition than B. napus, B. rapa, C. arvense, and B. juncea. The ovipositional and feeding preferences for C. album suggest that species of Chenopodiaceae were important hosts of M. configurata before vast monocultures of B. napus and B. rapa were introduced to western North America.

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.
