“…Various termiticidal components of hardwoods and softwoods have been extracted and identified (Saeki et al 1971, Lenz and Becker 1972, Saeki 1973, French et al 1979, Jurd and Manners 1980. Chemicals in termite resistant woods may be contact toxic to termites or act as antifeedants, repellents, or protozoacides (Carter 1979, Carter and Mauldin 1981.…”

Six wood products used in wall paneling were tested for resistance to feeding damage by the eastern subterranean termite, Reticulitermes jZuuipes (Kollar). Alaska-cedar, Cha~naecyparis nootkatensis (D. Don) Spach, fiber without wax and resin treatments normally used in paneling production was not a preferred food source in choice tests where all 6 wood products plus pine, Pinus palustti Mill., were simultaneously provided. However, the same nontreated Alaska-cedar fiber sustained severe damage when provided as the only food source in no-choice tests. Nontreated fiber of western hemlock, Tsugu heterophyllu (Raf.) Sarg., and hardboard and hardboard paneling made from a mixture of western hemlock and Douglas-fir, Pseudotsugu menziesii (Mirb.) France, sustained significant feeding damage in both choice and no-choice feeding tests. Pressed paneling mats made from Alaska-cedar or western hemlock exhibited antifeedant properties. Waxes, resins, and additives used in manufacturing these mats imparted resistance to R. fEauipes.

“…In trees, resistance may be due to the hardness of the timber or, more commonly, to chemicals in the wood which may be repellent to the termites (e.g. Rudman & Gay, 1967;Saeki et al, 1973;Sivapalan et al, 1977;Williams, 1965). For instance, resistance of Pinus sp.…”

Non-chemical control of termites in agriculture and forestry is attracting renewed interest following increasing restrictions on the use of persistent organochlorine (cyclodiene) insecticides. Non-chemical control involves methods which attempt, without using commercial pesticides, to (i) prevent termite access to the plants, (ii) reduce termite numbers in the vicinity of the plants or (iii) reduce susceptibility/increase resistance of the plants themselves. There have been few adequate trials of any of these methods. Numerous cultural procedures have been suggested, including measures to enhance plant vigour, to manipulate termite numbers and behaviour, and others whose mode of action is unclear. Many are simply part of good agricultural/ silvicultural practice and to be recommended. Biological control by predators or pathogens is unlikely to be successful due to the termites' social structure and behavioural responses to infected individuals and to loss of individuals to predators.

The term wood extractives covers a large number of different compounds which can be extracted from wood by means of polar and non-polar solvents. In a narrow sense extractives are those compounds which are soluble in organic solvents, and in this sense the term extractives is used in wood analysis (-» 3.2.4.). But watersoluble carbohydrates and inorganic compounds also belong to the extractable substances.The portion soluble in organic solvents amounts to only few percent in the wood of trees from temperate zones, but the concentration can be much higher in certain parts of a tree, e.g. in branch bases, heartwood, roots, areas of sore irritation. Relatively high amounts of extractives are found in certain tropical and subtropical woods (Table 3-6). Various studies are concerned with the artificial induction of a high extractive production (up to 15%) in pines. In the case of treatment with the herbicide paraquat or similar compounds before harvest, areas soaked with resin (lightwood) are formed within the stem (Conner et al. 1977; Zinkel, McKibben 1978) (-» 18.7.).
