“…Therefore, it is reasonable that second-instar nymphs would have a higher response to this pheromone, because it may enable them to encounter host plants. However, the fact that only sexually mature nondiapausing males attract conspeciÞcs (Mizutani et al 2008) suggests that the R. pedestris pheromone has another function as a sex at- Fig. 4.…”

Riptortus pedestris (F.) (Heteroptera: Alydidae) females oviposit not only on host plants but also on nonhosts, which may impose high costs on nymphs in terms of locomotion energy and time searching for host plants. Therefore, we hypothesized that second-instar nymphs have developed adaptive traits that help them access host plants, because the first feeding stage occurs during the second instar in this bug. We compared responses to the aggregation pheromone, relative leg lengths, and locomotion performance using a servosphere locomotion compensator as tests of physiological, morphometric, and behavioral traits, respectively, among the instars. We also investigated the effects of delayed feeding in the second instar on subsequent survival and development. Our results indicated that second-instar nymphs might have responded more sensitively to synthetic aggregation pheromone than other instars. Morphological measurements showed that second-instar nymphs had the longest relative leg length compared with other instars. The experiment using the servosphere revealed that second-instar nymphs had higher locomotion performance than did older nymphs, which may allow second-instar nymphs to walk a distance comparable to older nymphs, although their body size is much smaller. However, we did find that more than a 48-h delay in feeding after the first-instar molt decreased subsequent survival rates and that a later first-feeding led to a longer developmental period during the second instar. We concluded that R. pedestris nymphs have evolved various adaptive traits to enhance the probability of accessing host plants in response to the costly oviposition habit of adult females that lay eggs on nonhosts.

“…Except for tridecyl and octadecyl 2-methylpropanoates, and tetradecyl, hexadecyl and octadecyl 3-methylbutanoates, and all 2-methylbutanoates from Table 2, all other esters were for the first time found to be secondary plant metabolites. All of the synthesized esters, with the exception of tetradecyl and octadecyl 3-methylbutanoates and octadecyl 2-methylpropanoate described in a previous report, [3] were fully spectrally characterized ( 1 H-and 13 …”

“…Due to the ethnomedicinal usage of S. pecten-veneris L. in Iran and Turkey [10] and because some esters of long-chain alcohols, found in bee secretions [11] lining the walls of their tunnels, are believed to protect the bees against microbial infections (in addition to having a pheromonal role [8,12,13] ), the synthetic esters were screened in an antimicrobial assay to try to determine their function in the plant organism.…”

Scandix pecten-veneris L. (Apiaceae) is a weed species used in Iran and Turkey for medicinal purposes. The latest phytochemical reports on this umbellifer date to the 1980s. Motivated by a recent discovery of a series of chemotaxonomically important volatile long-chain n-alkyl isomeric butanoates and pentanoates from a related taxon, S. balansae, the aim of this work was to reinvestigate the chemical composition of the essential oil of S. pecten-veneris. Gas chromatography (GC) and GC combined with mass spectrometry (MS) analyses of the root, aerial part and fruit essential oils revealed the presence of 14 isomeric butanoates and pentanoates of long-chain 1-alkanols (C 13 -C 18 , C 21 and C 23 ). A small synthetic library of the tentatively identified esters allowed the final identity corroboration and screening of their antimicrobial activity. Among 123 successfully identified compounds in seven samples, seven esters (n-C 15 , C 17 , C 21 and C 23 isobutyrates, as well as n-C 13 , C 15 and C 17 isovalerates) turned out to be new natural metabolites and these were fully spectrally characterized (nuclear magnetic resonance, infrared, MS). All detected esters were quantified by GC with flame ionization detector (FID) calibration curves: 0.02-3.27 mg of these esters per 100 g of dry roots, aerial parts or fruits. The availability of the synthetic library made it possible to examine structure-antimicrobial activity relationships. The reinvestigation of S. pecten-veneris essential oil by standard analytical methods and the application of the synthetic approach presented the possibility of identifying very rare minor plant metabolites previously unidentifiable and provided relevant data for dereplication of other related secondary metabolites.

“…The roots of Macrotomia densiflora (Boroginaceae) [35] was found to contain octadecyl 3methylbutanoate (2d). Octadecyl 2-methylpropanoate (2b) has been so far known as a constituent of Dufours gland secretion of a species of Amazon ants (Polyergus rufescens) [36] and as a pheromone content of the bean bugs Riptortus clavatus [37] and Riptortus pedestris [38].

Analyses by GC and GC/MS of an essential-oil sample obtained from dry fruits of Scandix balansae Reut. ex Boiss. allowed the identification of 81 components, comprising 91.4% of the total oil composition. Interestingly, the major identified volatile compounds were medium-chain-length n-alkanes, i.e., tridecane (6.7%), pentadecane (13.4%), and heptadecane (19.3%), and a long-chain homolog nonacosane (7.6%). A number of minor oil constituents, among them tetradecyl 3-methylbutanoate, and octadecyl 2-methylpropanoate, 3-methylbutanoate, and pentanoate, turned out to have a restricted natural occurrence not only in umbellifers but also in the Plant Kingdom, whereas the last ester is a new natural compound in general. The identity of these rare plant constituents that present excellent chemotaxonomic marker candidates for Scandix species was unambiguously confirmed by co-injection of the oil sample with appropriate standards, which were synthesized for this purpose and fully characterized ((1) H- and (13) C-NMR, IR, MS). To explore the possible applicability of the essential oils' compositional data in the taxonomy of Apiaceae, the herein studied and additional 58 oils obtained from Scandiceae taxa were compared using multivariate statistical analyses (MVA). MVA demonstrated that the evolution of the volatiles' metabolism of Scandiceae taxa was neither genera-specific nor follows their morphological evolution.
