“…HPLC-bioactivity-guided fractionations led to the isolation of costic acid (124) showing repellent activity against subterranean termite C. formosanus (Watanabe et al, 2005). Furthermore costic acid (124) had selective cytotoxic effects toward insect-derived Sf9 cells (Gonzalez-Coloma et al, 2005).…”

“…Several eudesmol isomers, and a eudesmane sesquiterpene acid and methyl ester derivatives were isolated from Callitris glaucophylla Thompson et Johnson and identified as termite repellents (4). The Cryptomeria japonica (L. f.) D. Don essential oil contains elemol as its major component (18.2%), and was recently identified as a repellent to silverfish (5).…”

Recent investigations on the sesquiterpene-rich Amyris (Amyris balsamifera L.) and Siam-wood (Fokienia hodginsii L.) essential oils revealed significant arthropod repellency and toxicity responses. Amyris essential oil and one of its major components, elemol, were evaluated in laboratory bioassays and identified as effective mosquito repellents, specifically characterized by high levels of contact and minimal spatial repellency. Mosquito responses to catnip (Nepeta cataria L.) essential oil are characterized with high spatial activity, but lack significant contact repellency. Sampling within the staticair bioassay chamber with solid-phase microextraction provided measurements of the relative concentration and distribution of volatiles. These results supported the differences observed in repellency between essential oil treatments. Essential oil mixtures containing both spatial (catnip) and contact (Amyris) repellents were made and showed high levels of residual control via both modes of action. Siam-wood essential oil scored high in both spatial and contact efficacy against mosquitoes. Observations during this study included signs of toxicity. Two of the primary components of Siam-wood essential oil were tested for 24-hour house fly (Musca domestica L.) topical mortality. Transnerolidol and fokienol were found to possess similar insecticidal activity (topical LD50 values ranged from 0.17-0.21 µmol/fly). Amyris essential oil was selected for additional testing with brown dog ticks (Rhipicephalus sanguineusLatreille) in a 'barrier' repellency assay. Individuals were observed repeatedly avoiding and moving away from surfaces treated with Amyris essential oil.

They found that bark and Heartwood extractives exhibited antitermitic activity in a certain percentage of concentrations.…”

The toxic effects of selected Malaysian timbers (Madhuca utilis, Anisoptera laevis and Endospermum malaccense) heartwood extracts were studied with the aim to determine and understanding the function of wood extracts as a natural protection against termite. The results show that no-choice experiments revealed toxic properties of all investigated extracts by the contact against Coptotermes gestroi and Coptotermes curvignathus. However, high termite mortality was only achieved with Madhuca utilis extracts and methanol solvents.
