Biology, Reproductive Capacity, and Foliar Consumption of Diabrotica speciosa (Germar) (Coleoptera: Chrysomelidae) in Different Host Plants
Bibliographic record
Abstract
Diabrotica speciosa is considered one of the most important agricultural pests in Latin America. Attacks various plant species including fructiferous, vegetable, cucurbit, dicotyledonous, and gramineous crops. The goal of this work was to evaluate the influence of different host plants, offered during the larval and adult stages of D. speciosa on their development, reproductive capacity, and foliar consumption. The insects were reared with corn in the larval stage and offered common bean, corn, soybean, forage turnip and wheat in the adult phase. In another essay, the larvae were reared with bean, soybean, forage turnip, corn, wheat, potato and adult stage offered only leaves of common beans to the insects. The insects reared with corn and fed on common bean leaves in the adult phase produced bigger numbers of eggs in contrast to the insects fed on other host plants. The longevity of adult specimens and the oviposition period were greater when adults of D. speciosa were fed on soybean, forage turnip, and common bean leaves, but these parameters were reduced in the insects fed on corn and wheat leaves. The viability of D. speciosa during the immature stage was greater when the larvae were fed with potato tubers or corn seedlings. However, the larvae reared on potato tubers exhibited a longer development period in contrast to larvae fed on other plants. In the foliar consumption tests, common bean leaves were preferred by adult of D. speciosa in contrast to other plants (soybean, corn and forage turnip) offered under free-choice conditions. On the other hand, in confinement conditions, common bean was preferred by insects when compared to turnip or corn leaves. The results showed that corn was the best food for the larval development of D. speciosa while common bean represented the most suitable host for the adults.

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.
