“…According to this definition, RIO is attractive in the absence of the masking odor and nonattractive when masking background odor has been added. Several studies have shown that masking of an attractant odor may be due to (a) neutralization of the behavioral response by compounds that elicit a repellent response when presented alone (Price et al 1980, Nottingham et al 1991, Isaacs et al 1993, Hori and Komatsu 1997, Held et al 2003, Mauchline et al 2005 or (b) inhibition by compounds that have no repellent activity per se (Thiery and Visser 1986, 1987, Yamasaki et al 1997, Costantini et al 2001. Therefore, according to this definition of masking, the behavioral response to RIO is masked by compounds that may or may not provide a signal when presented alone.…”

“…In contrast, the sesquiterpenoid (−)-germacrene-D (Fig. 3) is present in the leaf and trunk volatiles of the host of M. alternatus (Pinus densiflora Siebold & Zuccurin), but this compound disrupts the response of female M. alternatus in laboratory walking and flight assays (Yamasaki et al 1997). …”

This review summarizes the literature related to the chemical ecology of the Cerambycidae and provides a brief overview of cerambycid biology, ecology, economic significance, and management. Beetles in the family Cerambycidae have assumed increasing prominence as pests of forest and shade trees, shrubs, and raw wood products, and as vectors of tree diseases. Exotic species associated with solid wood packing materials have been notable tree killers in North American urban and peri-urban forests. In forested ecosystems native species respond to disturbances such as fires and windstorms, and initiate the biodeterioration of woody tissue. Eggs are laid by females, on or through the bark surface of stem and branch tissue of moribund, recently killed or decomposing woody plants; larval cerambycids (roundheaded woodborers) typically feed in the phloem and later in the xylem. Females will also, in some cases, select living hosts, e.g. adult conifer and angiosperm trees, for oviposition. Research on the chemical ecology of over 70 species has revealed many examples of attractive kairomones (such as floral volatiles, smoke volatiles, trunk and leaf volatiles, and bark beetle pheromones), repellents and deterrents, oviposition stimulants, short-and long-range sex pheromones, and defensive substances. Emerging generalities are that attractants tend to be monoterpenoids and phenolic esters; oviposition stimulants are monoterpenoids and flavanoids; short-range sex pheromones are femaleproduced, methyl-branched cuticular hydrocarbons; and long-range sex pheromones are male-produced α-hydroxy ketones and (α,β)-diols ranging in length from 6 to 10 carbons. The latter compounds appear to originate from glands in the male thorax; putative defensive substances originate from metasternal secretory pores or mandibular glands. In one unusual case, a flightless, subterranean female that attacks sugar cane produces a sex pheromone that is derived from the amino acid isoleucine. With significantly more than 35,000 species of Cerambycidae worldwide, these generalities will be subject to change as more species are examined.

“…8,9 Acting as a masking substance of attractants for Monochamus alternatus (Hope), 10 germacrene D is an important compound in the biological control of this cerambycid beetle, which is a vector of the pinewood nematode Bursaphelenctus xylophilus, a forest disease agent. 11 On the basis of the inflorescence essential oil composition, no infraspecific chemical differences have been reported for clary sage, whereas relevant differences have been found in the contents of linalool and linalyl acetate (15-70% and 14-77%, respectively) mainly due to the different origins of plants and to the condition of the plant material on distillation. 5,8,12,13 Generally, the oil is obtained from inflorescences and, to our knowledge, no studies have been performed on the leaf oil.…”

An Italian spontaneous biotype of clary sage (Salvia sclarea L.) was evaluated for its suitability to be cultivated in a semi-arid area and for the influence of these growth conditions on the essential oil composition. Seeds gathered from a spontaneous biotype were sown directly in the field, using a seeding density calculated to achieve a plant population of 7 plants/m 2 . Essential oils from the inflorescences and leaves of plants harvested at full flowering and early seed ripeness stages were obtained by steam distillation and characterized by GC and GC-MS. The plants showed a good tolerance to the semi-arid growth conditions, yielding more than 700 flowers/plant and about 21 g seeds/plant. Relevant qualitative and quantitative differences were detected between the essential oils from the inflorescences and leaves, the former being characterized by a high content of linalool (26-29%) and linalyl acetate (35-53%) and the latter only by sesquiterpenes, with germacrene D as the main compound (68-69%). Inflorescences at full flowering stage were richer in linalool,˛-terpineol and germacrene D, showing a lower content in linalyl acetate in comparison with those collected at early seed ripeness. The development stage did not influence the oil composition of leaves.
