Abstract
Benzyl benzoate was identified in extracts of the watery oviposition l esion formed by rice plants in response to oviposition by Sogatella fu rcifera. The water solution of benzyl benzoate exhibited ovicidal acti vity against S. furcifera eggs at concentrations of greater than or eq ual to 6.4 ppm at 25 degrees C. This ovicidal substance was not detect ed in either intact rice plant tissues or in non-watery oviposition si tes, where the mortality rate of S. furcifera eggs is much lower than it is in watery oviposition lesions.
