Benzyl benzoate was identified in extracts of the watery oviposition lesion formed by rice plants in response to oviposition by Sogatella furcifera. The water solution of benzyl benzoate exhibited ovicidal activity against S. furcifera eggs at concentrations of >__= 6.4 ppm at 25°C. This ovicidal substance was not detected in either intact rice plant tissues or in non-watery oviposition sites, where the mortality rate of S.furcifera eggs is much lower than it is in watery oviposition lesions.
