SANCHEZ VARELA, Alejandro  y  RODRIGUEZ LUNA, Isabel C. Mortality of larvae of spodoptera frugiperda by effect of fruit extracts of morinda citrifolia l. (noni). Rev. Bol. Quim [online]. 2017, vol.34, n.5, pp.138-141. ISSN 0250-5460.

ABSTRACT The fruit of noni (Morinda citrifolia L.) has an oval shape, it shows a green to white color, and, it becomes yellowish, with a bittersweet or bitter taste, and an unpleasant smell when ripe. Morinda citrifolia  is a plant with many applications, some of them little explored, as for instance, its insecticidal property. This plant contains diverse active principles that include among others: xeronine, damnacanthal, scopoletin and some terpenes. The widespread use of synthetic pesticides has led to the apparition of chemo-resistance in certain insect populations, with its consequent environmental impact. Such impact is particularly remarkable in the natural enemies of insect pests, as well as on groundwater, in soils and in the air. We have worked in the quest of prospective biological formulations based on natural products from plants and fruits for pest management. Some biological control strategies have been used in Mexico, including the use of extracts from plants manifesting toxic effects on pests. The objective of this study is the obtention of extracts of the fruit of noni (Morinda citrifolia L.) and its subsequent toxic evaluation on Spodoptera frugiperda larvae.
