“…In contrast, the monoterpenes also have ecological functions that are advantageous to the pest insect: they can act as precursors in pheromone biosynthesis (Lindström et al 1989;Seybold 1993;Byers 1995 and refs therein) or as primary attractants for opportunistic herbivores (Byers et al 1985;Tilles et al 1986;Jactel et al 1996;Kleinhentz et al 1999). The role of terpenes in host recognition by lepidopteran insects has been shown (Sadof & Grant 1997;Shu et al 1997).…”

The compositions of 23 monoterpene hydrocarbons of six pine species (Pinus syl6estris, P. yunnanensis, P. armandii, P. tropicalis, P. cubensis and P. caribaea) were compared, using multivariate data analysis. Four of the six species were clearly different from the other species in a Principal Components Analysis (PCA) model, based on the relative amounts (selective normalization) of the monoterpenes. The correlation coefficients between constituents were determined separately for each species and the strongest correlations were found between (+)-h-pinene and (+ )-camphene and between the corresponding (−)-enantiomers, in all species. This pattern, i.e. a good correlation in all species, was neither shown by the correlation of the structurally more similar (+ )-h/i-pinenes, nor by the ( −)-h/i-pinenes or within the enantiomeric pairs of h-pinene and i-pinene. For these pairs of monoterpenes, good correlations were found in some species. None of the species showed good correlations in all the investigated monoterpene pairs presented here. Correlations between monoterpenes in insect-attacked trees (P. cubensis and P. caribaea, attacked by Dioryctria horneana, and P. yunnanensis, attacked by Tomicus piniperda) were also determined. The results are discussed from chemotaxonomic and biosynthetic points of view.

“…In contrast, the monoterpenes also have ecological functions that are advantageous to the pest insect: they can act as precursors in pheromone biosynthesis [9][10][11] or as primary attractants for opportunistic herbivores, and even fungal symbionts and beetle gut bacteria converted tree monoterpenes such as α-pinene and myrcene to the corresponding pheromones [12][13][14][15][16].We were studied 3 species of Pinus (Table 1). Table 2 lists the volatile mono-and sesquiterpenes of needles of P. armandi, P. tabulaeformis, and P. bungeana from GC-MS analysis; 32 compounds have been identified from needles of P. armandi, and the principal constituents were β-caryophyllene (29.09%), followed by cadindiene (26.10%), α-caryophyllene (5.34%), α-pinene (4.27%), and D-limonene (1.00%), respectively.…”

Changes in the composition of volatile monoterpenes and sesquiterpenes of Pinus armandi, P. tabulaeformis, and P. bungeana in Northwest China

The volatile mono-and sesquiterpenes obtained from the needles and resin of Pinus armandi, P. tabulaeformis, and P. bungeana growing in the Qinling, Taibai, and Huanglong Mountain forest ecosystem were analyzed by means of GC-MS. Forty-eight constituents were identified, and α-pinene, β-pinene, 1R-α-pinene, β-caryophyllene, cadindiene, α-caryophyllene, D-limonene, and 1S-β-pinene were the major components of the mono-and sesquiterpenes in the needles and resin. The components of the volatile monoand sesquiterpenes from the needles and resin at Qinling, Taibai, and Huanglong Mountains had remarkable differences in three pine species, whereas the monopertene content such as α-pinene, β-pinene, D-limonene, and camphene were mostly changed in the growing stage. The intraspecies variation in the different ecosystems can be attributed to the species' geography and genetic variation, and even the adaptation of the pine species to different ecological environments. Moreover, monoterpenes and sesquiterpenes can be induced by the attack of bark beetles, of which the α-pinene, β-pinene, 1R-α-pinene, 1S-α-pinene, β-myrecene, and β-caryophyllene contents had positive relations with the attacking Dendroctonus armandi and D. valens.

“…The first period of pest mass occurrence, representing a significant threat, usually appears in May due to the migration of beetles from adjacent stands attracted to the monoterpenes emanating from the resin of fresh stumps left after harvesting of old coniferous trees in the reforested areas. These volatiles include α-pinen and 3-carene, which show synergistic effects with ethanol [15,16]. These compounds are also used in practice as kairomones in bait traps to attract and collect weevils.…”

Biological Control of Pest and Vector Insects

Weevils (Coleoptera: Curculionidae) are the most important pest insects of forest plantations established on clear-cut areas, and Hylobius abietis is a pest insect of great economic importance in Europe. Pinus sylvestris plantations and thickets established on sandy soils or postfire areas can be severely impacted by Cneorhinus plagiatus and Brachyderes incanus. Young pine forests weakened by biotic and abiotic factors are particularly susceptible to Pissodes castaneus. Buds and shoots of P. sylvestris trees are mainly damaged by Lepidoptera larvae. For many years, chemical treatments have been the main way of protecting forests against insects. At present, to reduce the pollution of forest environments with insecticides, the strategy of integrated pest management (IPM) was put into practice. It involves prophylactic measures to increase plant resistance to insect attacks and to select appropriate control methods based on a multistep decision support system (DSS). Nonchemical control measures aim at collecting pest insects in traps fitted with attractants and biological methods, mainly based on entomopathogenic nematodes (EPNs) and wood-decomposing fungi. Chemical insecticides are used only in cases of high threats to reforestation stands. This paper presents the state of knowledge concerning pest insect management in forest plantations in Europe, with particular emphasis on insects occurring in Poland.
