Zusammenfassung: | Soursop (Annona muricata L.) is a tropical species with a growing global interest due to its multiple properties, and its applications in health and agriculture fields. In order to contribute with the knowledge of the available acquis and promote its use to solve national problems, this research analyzed the proximal composition and the insecticidal potential of soursop seeds on the cogollero worm (Spodoptera frugiperda JE Smith), a Lepidoptera that threatens corn crops, one of the most important crops in the country. This research includes fruits available in the local market and classified according to international morphological markers. Proximal composition of seed meal samples was determined using the Association of Official Analytical Chemists (AOAC) methodologies, obtaining as a result: 4.29% moisture, 95.71% dry matter, 1.34% ash, 31.14% ethereal extract, 2.59% nitrogen, and 16.19% protein. To determine the insecticidal potential a bioassay was performed (48 hours) where the effect of complete seed and endosperm extracts obtained by Soxhlet extraction method were evaluated on the third larval stage of cogollero worm specimens reared in the laboratory from its hatching. The extracts were applied to the food (corn leaves) at five concentrations between 0.70 – 25.00%. The lethal concentration 50 (LC50) was 2.13% for endosperm extract and 1.85% for complete seed extract.
La guanábana (Annona muricata L.) es una especie tropical de interés mundial creciente debido a sus múltiples propiedades y sus aplicaciones en el campo de la salud y la agricultura. A fin de contribuir con el conocimiento del acervo existente y promover su utilización en la solución de problemáticas nacionales la presente investigación analizó la composición proximal y el potencial insecticida de las semillas de guanábana sobre el gusano cogollero (Spodoptera frugiperda J. E. Smith), un lepidóptero que amenaza el cultivo de maíz, uno de los rubros de mayor importancia en el país. En la investigación se incluyeron frutos disponibles en el comercio local clasificándolos según marcadores morfológicos internacionales. La composición proximal de las muestras de harina de semilla se determinó utilizando las metodologías descritas por Association of Official Analytical Chemists (AOAC) obteniendo como resultado: 4.29% de humedad, 95.71% de materia seca, 1.34% de cenizas, 31.14% de extracto etéreo, 2.59% de nitrógeno y 16.19% de proteína. Para la determinación del potencial insecticida se rea |
