Abstract

Several terpenoids and oils were screened for vapour toxicity and repellency against the termite, Odontotermes brunneus. In toxicity tests, knockdown time KT50 and KT90 values were derived at 5 mg/cm2. For repellency screening, a new experimental setup was designed and effective time ET50 and ET90 values were determined at 2 mg/cm2. Among the compounds screened, eucalyptus oil produced the fastest knockdown (KT50 24.8 min) while β-ionone was found to be the least effective (KT50 536.0 min). Terpeneol (anhydrous) afforded maximum persistence of 338.0 min, whereas the least persistence was obtained from linalool (78.9 min) which prevented 50% of the population from crossing over the treated barrier (ET50).

Résumé

Plusiers terpenoïdes et huiles ont été passés au crible pour la toxicité de leurs vapeurs et le pouvoir répulsif contre le termite Odontotermes brunneus. Dans les essais de toxicité, les valeurs pour le temps knockdown KT50 et KT90 ont été déduites à 5 mg/cm2. Pour le test de répulsivité, un nouveau dispositif expérimental a été conçu et les valeurs de période d'efficacité ET50 et ET90 ont été déterminés à 2 mg/cm2. Parmi les composés passés au crible, l'huile d'eucalyptus a produit le knockdown le plus rapide (KT50 24,8 min) tandis que β-ionone s'est revélée la moins efficace (KT50 536,0 min). Le terpenol (anhydre) a donné une persistence maximale de 338,0 min, tandis que la plus faible persistence a été obtenue avec le linalool (78,9 min), lequel a empêché 50% de la population de franchir la barrière traitée (ET50).
