Abstract:
The objective of the study was to evaluate the biocidal effect of the ethanolic extract of Nerium oleander leaves in the control of larvae of Prodiplosis longifila infested in asparagus shoots. Phytochemical screening was carried out using the Miranda & Cuellar method. The cardiotonic glycosides were obtained using the partition coefficient method. The evaluation of the biocidal effect was performed every 4, 12, 24 and 48 hours following the experimental design by randomized complete blocks with a factorial arrangement of 5x4x1, facing concentrations that were 100%, 60% and 40% volume/volume. The ethanolic extract, reported the presence of lactones, steroids, catechins, reducing sugars, resins, saponins, polyphenols, flavonoids, cardiotonic glycosides and leucoanthocyanidins. The concentration of the extract at 60% volume/volume showed a mortality rate of 40.5% of larvae of Prodiplosis longifila.
