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.
