Annonaceae species are interesting sources of structurally diverse compounds with insecticidal proper-ties. Therefore, a screening assay was conducted on ethanolic extracts prepared from the leaves, branches,and seeds of different Annonaceae species (Annona cacans Warming, Annona montana Macfadyen, Annonamucosa Jacquin, Annona reticulata Linnaeus, Annona sylvatica A. St.-Hil., and Duguetia lanceolata A. St.-Hil.) to detect promising sources of compounds with action against Spodoptera frugiperda (J.E. Smith)(Lepidoptera: Noctuidae). The ethanolic extract from A. mucosa seeds (ESAM) was the most active treat-ment, causing significant acute toxicity (LC50= 842.9 mg kg−1) and pronounced larval growth inhibition(EC50= 580.4 mg kg−1) after 7 days of exposure to an ESAM-treated diet. Furthermore, ethanolic extracts(at 1000 mg kg−1) from seeds of A. cacans, A. montana, A. mucosa, and A. sylvatica; leaves and branches of A.reticulata; and D. lanceolata leaves only caused sublethal effects, reducing the S. frugiperda larval weight.Nevertheless, ESAM (at LC90) showed an efficacy similar to that of two commercial insecticides of nat-ural [azadirachtin + 3-tigloylazadirachtol (Azamax®1.2 EC)] and synthetic [chlorantraniliprole (Premio®20 SC)] origins, which were tested at the registered concentration for S. frugiperda control. Thus, usingdifferent chromatographic techniques, bioguided fractionations were conducted and led to the isolationof acetogenin bis-tetrahydrofuran rolliniastatin-1, which was identified as the primary compound fromthe most active fractions of ESAM. This compound, which caused both strong mortality and pronouncedgrowth inhibition to S. frugiperda, may be a useful component for the integrated management of thisimportant pest species.

The results of an evaluation of the impact of traditional silvopastoral system on floristic and phytosociology of the Mixed Ombrophilous Forest (MOF) remnants, named caívas, in the North Plateau of Santa Catarina, South of Brazil are shown here to contribute to a better understanding of the impact of human activities on natural environments,. There was significant heterogeneity in floristic and structural aspects among the remnants. They exhibited high floristic integrity, with the presence of species typically registered in MOF. On the other hand, the incidence of exotic species was inexpressive. The predominance of smaller plant individuals than expected for adults of the species, combined with the predominance of secondary and pioneer species indicate the occurrence of repeated disturbances over the years. It is urgent to identify technological alternatives to enable appropriate foraging and increase in livestock production, ensuring economic and social sustainability with less environmental impact. |
