The Inhibitory Effects of Obtusaquinone and Related Chemicals on the Wood-Boring Crustacean Limnoria.
Abstract
The writer conducted an experiment on the inhibitory effects of obtusaquinone on limnoria to find a new wood preservative. Three species were employed: Limnoria tuberculate; L. quadripunctata; and L. tripunctata. The panels were impregnated in a vacuum chamber by bleeding the aceton-dissolved solution into the chamber, then exposing to nitrogen gas under 100 pounds pressure for 1 hour. Panels were placed into 50-gallons aquariums with infested wood from Boston; Chatham, Mass.; and Marina Del Rey, Calif. Test parameters were: salinity, 31% + or - 1%; temperature, 20.0 C + or - 2.5 C; pH 7.8 + or - 0.1. Present in the tanks were source wood, test panels, solder braces, air stones, and one air filter. Test panels were removed from contact with the Massachusetts wood after 5 months - and from the California wood after 4 months of exposure. The new N.R.L. derivative of obtusaquinone was effective and resisted attack in all control tanks. Further research should be conducted and sponsored by the U.S. Navy with this new derivative in order to study its effect on other wood boring organisms as teredos and pholads, etc. (Author)
