“…Wood type and size affect conspecific interactions and production of secondary reproductives of drywood termites (Evans et al, 2011;Korb, 2006), as do wood anatomy and volatile emissions (Himmi et al, 2016;Scheffrahn & Rust, 1983;Xu, Feng, Zhong, Zheng, & Chen, 2015). 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).…”
