Biomass and Bioenergy. 75:150-154. Interpretive Summary: Phycitine moths are well known worldwide as highly destructive stored product pests, often feeding on seeds. A phycitine species, Ectomyelois muriscis, was recently discovered in Mexico to feed on Jatropha curcas, known as the physic nut. The seeds of this plant produce high quality biofuel, 27-40% oil in seeds, which has been used for automobiles and jets. This information is useful to agriculturalists that grow this plant species to extract oil for biofuel.
Technical Abstract: The natural infestation of fruits and stems of Jatropha curcas L. (Euphorbiaceae) by larvae of the pyralid moth Ectomyelois muriscis (Dyar) (Lepidoptera: Pyralidae) is reported for the first time. Populations of E. muriscis on J. curcas were observed in various parts of the state of Chiapas, southern Mexico. Feeding damage by larvae resulted in the destruction of J. curcas seeds. We conclude that this insect is a potential pest of J. curcas cultivation in this region.
