Evaluation of host susceptibility, preference and offspring performance of Zeugodacus cucurbitae (Coquillett) (Diptera: Tephritidae) on different hosts
Bibliographic record
Abstract
Abstract The melon fruit fly, Zeugodacus cucurbitae (Coquillett) is a quarantine insect pest worldwide and affects the vegetable quality through its direct feeding and indirectly by passing way for secondary pathogens. This study investigated the host susceptibility, preference and offspring performance of Z. cucurbitae under the laboratory conditions. Different vegetable hosts i.e., brinjal (Solanum melongena L.), bitter gourd (Momordica charantia L.), zucchini (Cucurbita pepo L.), bottle gourd (Lagenaria siceraria [Molina] Standley) and cucumber (Cucumis sativus L.) were tested under no choice and free choice tests. Results showed that C. sativus and C. pepo have highest number of visits/host and oviposition puncture/host. C. sativus showed highest pupal recovery and pupal weight in both only choice and free choice test. While, highest percentage of emergence and female off springs were observed in C. pepo under only choice and free choice scenarios. Furthermore, maximum deformities in progeny were observed in case of L. siceraria under both test case scenarios. The current study provides exploratory support that fruit flies respond differently to host species that co-exists in field under choice and no choice test. Further, hosts of advantage to fruit flies are adopted more. The host and choice preference of fruit flies have the influence on the pest management strategies for the vegetable crops.
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.
