Female sex pheromone of Glossosphecia romanovi (Lepidoptera: Sesiidae): identification and field attraction.

In field screening tests of synthetic pheromone candidates for Japanese sesiid species, a mixture of (3Z,13Z)-octadecadien-1-ol and (3Z,13Z)-octadecadienyl acetate successfully attracted male moths of Glossosphecia romanovi, a harmful pest of vine trees. The GC-EAD and GC-MS analyses of the pheromone gland extract revealed that the female moths produced the alcohol and acetate in a ratio of about 20:1, in addition to three other minor structure-related components.

Identification and characterization of a new vitivirus from grapevine.

New virus-like sequences, TvAQ7 and TvP15, were found in a Japanese grapevine accession of OKY-AQ7 (cv. Aki Queen) and of OKY-P15 (cv. Pione) by nested RT-PCR to simultaneously amplify a segment of the RNA-dependent RNA polymerase (RdRp) gene from members of the genera Vitivirus and Foveavirus.
