Study of the efficacy of oil extracted from the soursop "Annona muricata" on adults of the "Bactrocera dorsalis" fruit fly

Abstract

The soursop is an oleaginous plant whose seeds are much feared for their toxicity. [1,2] . Its oil is extracted from the kernels using a soxhlet device using cyclohexane. The oil is then separated from the cyclohexane by rotavapor distillation at 45°C and dried in a desiccator. Its physical-chemical analysis showed a predominance of unsaturated fatty acids with a high sterol content (over 80% in β-Sitosterol and stigmasterol) determined by Gas Chromatography (GC). This oil has been tested on adults of the main mango pest, Bactrocera dorsalis, to assess its insecticidal activity. The Study of …
