“…The deterrent effect of the monoterpenes tested in our study is confirmed by previous results (Niccoli et al, 2008;Tiberi et al, 1999Tiberi et al, , 2004. (R)-(+)-limonene had the highest deterrent effect (lower number of PPM egg masses) in 2003, agreeing with previous trials (Niccoli et al, 2008;Tiberi et al, 1999Tiberi et al, , 2004.…”

“…As regards PPM laying activity, instead, (R)-(+)-limonene, (S)-(−)-limonene, and (1S)-(−)-␤ pinene in a water solution sprayed onto pine crowns showed a deterrent effect (Tiberi et al, 1999. To overcome the difficulties of spraying pine crowns, such as tree height and an uneven distribution of substances, in another study monoterpenes were applied by dispensers placed on the pine crown; this showed an even higher effect against PPM females than the spraying treatment (Niccoli et al, 2008). In light of those findings, for this paper (1S)-(−)-␤-pinene, (±)-limonene, (R)-(+)-limonene, and (S)-(−)-limonene were tested in 2003 and 2004 in dispensers of different sizes to verify their efficacy as PPM control tools, as well as their stability inside dispensers.…”

“…On the other hand, the presence of nonhost species is known to lead to chemical barriers to host location through the disruption of olfactory host recognition. Such mechanisms have been described, for example, in the case of coniferinhabiting bark beetles (Huber and Borden 2001) and might act similarly on PPM, as it is sensitive to various volatile terpenoids (Tiberi et al 1999;Kanat and Alma 2003;Niccoli et al 2008). More data are necessary to test these hypotheses in the case of PPM.…”

Landscape composition and physiognomy affect community structure and species distribution across space and time. The pine processionary moth (PPM) (Thaumetopoea pityocampa Den. & Schiff., Lepidoptera, Notodontidae) is a common pine defoliator throughout southern Europe and Mediterranean countries. We surveyed the spatiotemporal distribution of the PPM in a pine plantation forest in southwestern France and used the density of the winter nests as a proxy for population density. The study spanned 4 years (2005)(2006)(2007)(2008) and showed a high temporal variability in nest density. We found a strong edge effect with nest densities at stand edges more than twice as large as within-stand densities. At the landscape scale, the spatial distribution of the moth exhibited a significant spatial autocorrelation in 3 out of 4 years of our study. The spatial scales of the autocorrelation ranged from ca. 2 km to more than 22 km. We found a positive correlation between spatial distributions corresponding to certain sampling years, but the relationship was not systematic. Landscape configuration appeared to be an important driver of the PPM spatial pattern. Bivariate Moran's I correlograms showed that patch richness density as well as the percentage of local landscape covered by various land uses were correlated with population density. The study showed that accounting for landscape characteristics may be important in order to understand forest insect pest distribution, even in cases where the host species is abundant and homogeneously distributed throughout the study area, e.g., pure plantation forests.

“…It is also known that pinene enantiomers differ in their biological effects. In comparison with the (þ)-enantiomer, (À)-b-pinene exhibited stronger toxicity against larvae of Culex pipiens, and significantly reduced the oviposition activity of Thaumetopoea pityocampa in studies previously performed by Michaelakis et al [31] and Niccoli et al [32]. In relation to this, the relatively high content of (À)-b-pinene in N. arvensis and N. nigellastrum seed EOs indicates their possible insecticidal properties.…”

In this study, we analyzed the chemical composition of volatile oils hydrodistilled from seeds of Consolida regalis, Delphinium elatum, Nigella hispanica, and N. nigellastrum using GC and GC/MS. In C. regalis, octadecenoic (77.79%) and hexadecanoic acid (8.34%) were the main constituents. Similarly, the oils from D. elatum and N. hispanica seeds consisted chiefly of octadecadienoic (42.83 and 35.58%, resp.), hexadecanoic (23.87 and 28.59%, resp.), and octadecenoic acid (21.67 and 19.76%, resp.). Contrastingly, the monoterpene hydrocarbons α-pinene (34.67%) and β-pinene (36.42%) were the main components of N. nigellastrum essential oil. Our results confirm the presence of essential oils in the family Ranunculaceae and suggest chemotaxonomical relationships within the representatives of the genera Consolida, Delphinium, and Nigella. In addition, the presence of various bioactive constituents such as linoleic acid, (-)-β-pinene, squalene, or carotol in seeds of D. elatum, N. hispanica, and N. nigellastrum indicates a possible industrial use of these plants.
