Abstract
The work described in this paper has demonstrated that chemically modified Corsican pine sapwood with a homologous series of linear chain carboxylic acid anhydrides provided bioprotection against the subterranean termites Reticulitermes flavipes. By varying the reaction time, various levels of modifications were obtained. There was no significant reduction in feeding above 16% WPG (weight percent gain due to modification), suggesting that modification to WPGs greater than this did not offer additional protection. The type of anhydride employed has little influence on resistance against termites.
Zusammenfassung
In dieser Studie wird gezeigt, dass korsisches Kiefernsplintholz, das mit einer homologen Reihe unverzweigter Carbonsäureanhydride behandelt wurde, einen Schutz gegen die Bodentermite Reticulitermes flavipes bietet. Unterschiedliche Einwirkzeiten ergaben eine unterschiedliche Wirksamkeit der Behandlung. Ab einer Einbringmenge über 16% (Massezunahme, WPG) reduzierte sich der Befall nicht signifikant. Dies lässt darauf schließen, dass eine höhere Einbringmenge keinen erhöhten Schutz bietet. Die Art des verwendeten Anhydrids hat dabei keinen nennenswerten Einfluss auf die Termitenresistenz.
