Laboratory evaluation of the effects of <i>Manilkara subsericea</i> (Mart.) Dubard extracts and triterpenes on the development of <i>Dysdercus peruvianus</i> and <i>Oncopeltus fasciatus</i>

Abstract

The results indicate that extracts and triterpenes from Manilkara subsericea act as potent growth inhibitors of phytophagous hemipteran nymphs. It is also concluded that the mixture of several different molecules in the extracts used produces synergic effects that do not occur after using the triterpenes (PFT) alone. These secondary metabolites in the M. subsericea extracts can potentially be used in integrated control programmes against crop pests.
