Effect of an entomopathogenic nematode,<i>Steinernema carpocapsae</i>on haemocyte profile and phenoloxidase activity of the Colorado potato beetle,<i>Leptinotarsa decemlineata</i>
Bibliographic record
Abstract
The Colorado potato beetle (CPB), Leptinotarsa decemlineata Say is the most destructive insect pest of potato in many areas of the world. Little is known about the haemocyte types of the CPB and its plasma phenoloxidase (PO). In this regard, we investigated the haemocyte profile and PO of CPB and its immune response to the entomopathogenic nematode, Steinernema carpocapsae. Five types of haemocytes, the plasmatocytes (~67.4%), granulocytes (~23.5%), oenocytoids (~2.4%), spherulocytes (~0.25%) and prohaemocytes (~6.5%) were identified in fourth instar CPB larvae. Total haemocyte counts (THCs) were significantly reduced in nematode-injected insects compared with control groups (P < 0.05). Nematode cellular encapsulation observed in haemolymph of nematode-injected insects may partially explain decreased THCs. Plasma PO assay showed increased PO activity in nematode-injected insects compared with control groups (P < 0.05). Plasma PO assay on native polyacrylamide gel electrophoresis (PAGE) assay with L-3, 4-dihydroxyphenylalanine as substrate showed five bands (with molecular weights of approximately 200, 118, 68.5, 62.5 and 58.75 kDa).
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
