“…The damage observed for impregnated samples was lower than that found by Oliveira et al (2017) for the wood of seven species of Eucalyptus coming from trees at 16 years, thus proving the improvement in the resistance of the impregnated samples, regardless of the oil and I 2 percentage used.…”

“…wood, in addition to two holes in the samples of this wood being observed and termite mortality was 17.50%, which differed from other species such as Australian cedar, cacunda, cupiúba, cedar rose and pequi. Oliveira et al (2017) found severe damage (score 4) to Pinus sp. wood subjected to the same species of termites, with 15 holes and mortality of 34.4%, which was similar to that in the wood of seven Eucalyptus species at 16 years of age.…”

Natural products have been studied in order to ensure environmental sustainability, human health, and diminish the use of traditional products. The objective of this study was to evaluate the efficiency of pure andiroba (Carapa guianensis), copaiba (Copaifera langsdorffii) and jatropha (Jatropha curcas) oils and enriched with iodine (I 2) on the biological resistance of Pinus elliottii wood to dry-wood termites (Cryptotermes brevis). The oils were enriched with 1%, 3%, and 5% of I 2 and impregnated into the wood by cold immersion. The treated samples were subjected to volatilization and leaching. Volatilization and leaching did not affect the loss of mass caused by termites, except for treatments with pure and enriched with 1% iodine copaiba oil. Leached samples were more damaged. The addition of iodine to the oils resulted in a greater efficiency against termites. Andiroba (3% and 5% I 2) and jatropha oils (5%) were the most efficient, providing total termite mortality.

“…Thus, it may present high, medium or low resistance to the action of these agents. It is one of the basic requirements that limits its use as sawn material (Oliveira et al, 2017), and the more marked it is, the greater its degree of acceptance in relation to the others (Oliveira et al, 2017), allowing its use without the need for toxic and environmentally harmful chemicals.…”

This work aimed to evaluate the biological resistance of Australian red cedar (Toona ciliata) and Eucalyptus woods to the Cryptotermes brevis (Kalotermitidae) dry wood termite species. The species used to evaluate natural resistance to insect attacks were Australian red cedar from 6 and 12-year-old plantations installed in the mountainous region of the Espírito Santo state, and commercial adult Eucalyptus sp. wood provided by a sawmill located in the South of Bahia state. Fitting and evaluation of the experiment followed the recommendations of the Institute for Technological Research of the State of São Paulo. The three woods differed as to their susceptibility to attack by dry wood termites when the damage caused in the samples was considered, with the most consumed species being the 12-year old Australian red cedar, while the Eucalyptus wood was less susceptible to damage.

“…Curiously, resistance of tropical wood and its underlying causes were seldom investigated and the studies carried out so far focus on recognizing preferences and mainly by subterranean termite species with few exceptions (Cornelius & Osbrink, 2015;Lee, Bardunias, Su, & Yang, 2008;Lee & Forschler, 2016;Manzoor, Abbas, & Latif, 2015;Oberst, Lai, & Evans, 2018;Rust & Reierson, 1977;Rust & Su, 2012;Scheffrahn & Rust, 1983). Nonetheless, varied resistance to the West Indian drywood termite exists (Cosme, Haro, Guedes, Della Lucia, & Guedes, 2018;Gonçalves & Oliveira, 2006;Oliveira, Paes, & Vidaurre, 2017), and the wood physical properties, namely hardness and specially density, are important determinants of colonization and wood consumption by this invasive pest species (Cosme et al, 2018).…”

Wood‐feeding, nesting and production of secondary reproductives are key determinant traits of invasive species of drywood termites, and the West Indian drywood termite Cryptotermes brevis (Walker) is one of their major examples of worldwide concern as pest species of structural lumber, furniture and other wood products. The problem and losses by this species are determined by the prevailing wood characteristics. However, despite the current widespread occurrence of this species in the tropics, except Asia, tropical wood resistance and underlying mechanisms of resistance against this termite are scarcely known. Nonetheless, wood hardness and particularly wood density were recently recognized as important underlying traits for C. brevis resistance in tropical woods, but the chemical wood constituents were not considered. Here, we assessed tropical wood resistance to the invasive termite species C. brevis and tested the relevance of their holocellulose, lignin and (total) extractive contents preventing termite infestation. Free‐choice and no‐choice tests were carried out in parallel with wood chemical characterization. Resistance to the West Indian termite varied with wood species in terms of both colonization and consumption, but only under free‐choice testing because without choice, no significant difference was detected among wood species. Regardless, none of these traits were significantly correlated with wood resistance to C. brevis. Therefore, wood physical resistance, particularly wood density, seems the main recognized determinant of tropical wood resistance against the West Indian drywood termite. The pattern of termite movement on the surface of soft, mid and hard wood was also consistent with this conclusion.
