“…test recorded non-significant values according to the wood types, tree species, and physical properties of the woods. These results reflect those of Al-Mallah et al, (2009) who reported that there is not precise correlation between physical properties of wood and amount of wood loss in termite feeding preferences to the tested woods. On the other hand, Behr et al, (1972) in their research supporting the correlation between the amount of termite feeding by (percentage wood weight loss) and both wood hardness and density.…”

“…Mustafa (2004) reported that Microcerotermes feeds on any woods such as, sound or decayed, and lays on or in contact with the ground. The wood species, which suggested for most part of building structures and interior designs, were divided into different groups depending upon the wood density and wood strength (Wong et al 1983 andAl-Mallah-et al, 2009). Susceptibility and resistance to termite had been measured by Always et al, (1989) to determinate the effect of the termite invasion on local and imported wood in Iraq.…”

The current study investigated the sensitivity of different wood species to the termite, Microcerotermes diversus, in two different locations. The results showed that both softwood and hardwood of White Willow, Salix alba; Melia, Melia azedarach; pine, Pinus brutia and Mediterranean Cypress, Cupressus sempervirens are highly susceptible to the termite invasion under physically infection conditions in Sami Abdulrahman Park, Erbil city, Iraq. Moreover, the sensitivity of the species to the termite invasion was significantly different under natural infection in Grdarasha after 22 weeks from early April to the end of September 2017. In addition, the White Willow (Salix alba) species showed more sensitivity to the termite infection in comparison with others species, where the mean of wood green weight, wood dry weight (before infection), wood dry weight (after infection) and specific gravity loss during the period of experiment of the White Willow were 2.2609g, 2.1584g, 1.5983g and 0.5139 respectively. Furthermore, Cupressus sempervirens was more resistant in comparison with other wood species to the termite in both locations where green weight of wood 3.010g and Dry weight of wood (after infection) 2.287g, Dry weight of wood (befor infection) 2.877g and Specific gravity 0.685. Generally, this study revealed that there is no definite association between both physical properties and moisture content of softwoods and hardwoods with termite preference.
