“…4), suggesting that this compound may be a part of the aggregation pheromone. Similarly, A. eugenii males emit compounds 2, 4, 5, and 6, but they also emit compounds 3 and 7 (Table 1; Eller et al, 1994). In the 1999 study, however, geraniol was emitted only by males; thus, all six compounds were designated as "male-specific" (Eller et al, 1994).…”

“…Previous studies have identified semiochemical-based attractants, i.e., aggregation pheromones, host-plant volatiles, and their combinations, which in some cases have been used successfully to monitor Anthonomus species (e.g., Tumlinson et al, 1969;Dickens, 1989;Eller et al, 1994;Innocenzi et al, 2001;Tinzaara et al, 2007). For example, Dickens (1989) showed that the green leaf alcohols (E)-2-hexen-1-ol, (Z)-3-hexen-1-ol, and 1-hexanol in combination with the boll weevil, Anthonomus grandis Boheman, aggregation pheromone enhances trap captures of boll weevils compared to the pheromone alone.…”

Identification and Field Evaluation of Attractants for the Cranberry Weevil, Anthonomus musculus Say

et al. 2011

Studies were conducted to develop an attractant for the cranberry weevil, Anthonomus musculus, a pest of blueberry and cranberry flower buds and flowers in the northeastern United States. In previous studies, we showed that cinnamyl alcohol, the most abundant blueberry floral volatile, and the green leaf volatiles (Z)-3-hexenyl acetate and hexyl acetate, emitted from both flowers and flower buds, elicit strong antennal responses from A. musculus. Here, we found that cinnamyl alcohol did not increase capture of A. musculus adults on yellow sticky traps compared with unbaited controls; however, weevils were highly attracted to traps baited with the Anthonomus eugenii Cano aggregation pheromone, indicating that these congeners share common pheromone components. To identify the A. musculus aggregation pheromone, headspace volatiles were collected from adults feeding on blueberry or cranberry flower buds and analyzed by gas chromatographymass spectrometry. Three male-specific compounds were identified: (Z)-2-(3,3-dimethyl-cyclohexylidene) ethanol (Z grandlure II); (Z)-(3,3-dimethylcyclohexylidene) acetaldehyde (grandlure III); and (E)-(3,3-dimethylcyclohexylidene) acetaldehyde (grandlure IV). A fourth component, (E)-3,7-dimethyl-2,6-octadien-1-ol (geraniol), was emitted in similar quantities by males and females. The emission rates of these volatiles were about 2.8, 1.8, 1.3, and 0.9 ng/adult/d, respectively. Field experiments in highbush blueberry (New Jersey) and cranberry (Massachusetts) examined the attraction of A. musculus to traps baited with the male-produced compounds and geraniol presented alone and combined with (Z)-3-hexenyl acetate and hexyl acetate, and to traps baited with the pheromones of A. eugenii and A. grandis. In both states and crops, traps baited with the A. musculus maleproduced compounds attracted the highest number of adults. Addition of the green leaf volatiles did not affect A. musculus attraction to its pheromone but skewed the sex ratio of the captured adults towards females. Although the role of plant volatiles in host-plant location by A. musculus is still unclear, our studies provide the first identification of the primary A. musculus aggregation pheromone components that can be used to monitor this pest in blueberry and cranberry pest management programs.

“…No pheromones have been described for scarab species of the subfamily Cetoniinae, but other scarab species exhibit considerable diversity in pheromone semiochemistry, and several small aromatic compounds have been identified as pheromone components (e.g., phenol, anisole, and methyl benzoate) (reviewed in Leal 1998). On the other hand, some scarab attractants have been found in flowers (Knudsen et al 2006), and the use of plant volatiles, including PAA (Honda 1980;Bellas and Hölldobler 1985), as attractants with pheromones has been observed in several insects (Boch and Shearer 1962;Baker 1989;Eller et al 1994;Hassanali et al 2005;Bartelt et al 2009;Kim et al 2009). …”

Pheromone-based Mating and Aggregation in the Sorghum Chafer, Pachnoda interrupta

et al. 2010

Adults of the sorghum chafer, Pachnoda interrupta Olivier (Coleoptera: Scarabaeidae: Cetoniinae), form aggregations during the mating period in July, but also in October. The beetles aggregate on food sources, e.g., Acacia spp. trees or sorghum with ripe seeds, to feed and mate. During the mating season, field trapping experiments with live beetles as bait demonstrated attraction of males to unmated females, but not to mated females or males, indicating the presence of a female-emitted sex pheromone. Unmated females combined with banana (food source) attracted significantly more males and females than did unmated females alone. Other combinations of beetles with banana were not more attractive than banana alone. Thus, aggregation behavior appears to be guided by a combination of pheromone and host volatiles. Females and males were extracted with hexane during the mating period, and the extracts were compared by using GC-MS. In a field trapping experiment, 19 compounds found only in females were tested, both singly and in a mixture. Traps baited with one of the female-associated compounds, phenylacetaldehyde, caught significantly more beetles than any other treatment. However, the sex ratio of beetles caught in these traps did not differ from that of control traps and it is possible that other components may be involved in the sex pheromone signal. Furthermore, traps baited with a mixture of all 19 compounds attracted significantly fewer beetles than did phenylacetaldehyde alone.

Supercritical carbon dioxide extraction of cedarwood oil: a study of extraction parameters and oil characteristics

The extraction of cedarwood oil (CWO) using supercritical carbon dioxide (SC‐CO2) has been investigated with respect to the effects of extraction temperature and pressure, length of extraction, and age of cedarwood chips. Steam distilled and SC‐CO2 derived CWOs were compared by gas chromatography and sensory evaluation. The extraction of CWO increased with extraction temperature, except at the lowest pressure utilised. The highest percentage contribution of thujopsene to the SC‐CO2 derived CWO occurred with the combination of 1500 psi and 70°C or 100°C. Essentially all of the CWO was extracted from the wood matrix in the first 10 min, however, complete extraction of water required ca. 25 min. The amount of CWO extracted decreased with increasing age of the cedarwood chips. This decrease was greatest for the more volatile hydrocarbon components, thujopsene and cedrene. The mean weight percentage yields of CWO for steam distillation and SC‐CO2 extraction were 1.3 and 4.4%, respectively. An experienced analytical sensory panel selected the SC‐CO2 derived CWO as being more similar to the original cedarwood chips than the steam distilled CWO. Volatile collections performed on SC‐CO2 extracted, steam distilled and unextracted cedarwood chips indicated that the SC‐CO2 extracted chips released almost no volatiles, whereas the unextracted chips released a higher amount of volatiles. The steam distilled cedarwood chips released an intermediate level of volatiles. Copyright © 2000 John Wiley & Sons, Ltd.
