Resumen o descripción
A number of metabolites isolated and identified from cuticular waxes have been used as chemotaxonomical markers and to
explain the role of the wax layer in plant-insect and plant-pathogen interactions. Chromatographic analysis of the cuticular wax from pinnae
of five coconut palm ecotypes showed that the three main components
(I, II, III) in the wax can be used as chemotaxonomical markers for
classification. The positive correlation found between the content of
metabolites I, II, and IIIin the wax from the various ecotypes and their
resistance or susceptibility to the lethal yellowing disease of coconut
palms, did not coincide with the results obtained in an antifeedant assay. The results suggest that while the individual components do not
play a significant role in the palm-insect interaction, the full composition of the cuticular wax does.
