Resistance to insects is not classified by levels but using a binary principle (\u00absensitive\u00bb or \u00abnon-sensitive\u00bb) depending on the species involved. The main insects that attack wood in buildings are: the house longhorn beetle (Hylotrupes bajulus), which mainly attacks conifers; Lyctus beetles, which primarily attack hardwoods rich in starch; and the common furniture beetle (Anobium punctatum), commonly known as a \u00abwoodworm\u00bb.<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Heartwood<\/td><td class=\"has-text-align-left\" data-align=\"left\">Heartwood, physiologically inactive, generally more durable.<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Monoscent essence<\/td><td class=\"has-text-align-left\" data-align=\"left\">Species in which a single individual bears distinct male and female flowers.<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Edaphic requirement<\/td><td class=\"has-text-align-left\" data-align=\"left\">Species' requirements regarding soil characteristics (texture, pH, drainage, fertility).<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Bundled<br>(rooting)<\/td><td class=\"has-text-align-left\" data-align=\"left\">Root system comprised of numerous roots of similar diameter, with no dominant taproot.<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Gemmotherapy<\/td><td class=\"has-text-align-left\" data-align=\"left\">Therapeutic use of plant embryonic tissues (buds, young shoots).<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Grungy<\/td><td class=\"has-text-align-left\" data-align=\"left\">Root-guiding culture container to promote functional rooting.<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">JANKA (N.)<\/td><td class=\"has-text-align-left\" data-align=\"left\">The Janka hardness test measures a wood's resistance to indentation by a standard-sized steel ball.
