“…A few of the metabolites found in our study, such as 2-heptanone, heptanol, and 3-methyl-4-ethylpentanol, have been previously identified in the volatiles of ripe and overripe berries of C. arabica [18]. Similarly, metabolites such as methyl salicylate, α-copaene and δ-cadinene have been identified in volatiles released by the healthy ripe berries of C. canephora [20].…”

One of the major obstacles to coffee production worldwide is the damage caused by the coffee berry borer Hypothenemus hampei (Ferrari; Coleoptera: Curculionidae). When searching for host fruits, females are attracted to the volatiles the fruits release. In this study, the volatiles released by the ripe and dry fruits of Coffea arabica and C. canephora were analyzed by gas chromatography-electroantennography (GC-EAD) and identified by gas chromatography-mass spectrometry (GC-MS). The areas of the response peaks were analyzed using canonical discriminant analysis. The results of the statistical analysis demonstrated the presence of 4 distinct groups of volatiles released from ripe and dry C. arabica and C. canephora. A few of the most influential compounds in the canonical discriminate analysis also elicited antennal activity (GC-EAD) in the flying female coffee berry borers, specifically 2-heptanone, 2-heptanol, 3-ethyl-4-methylpentanol, phenyl ethyl alcohol, methyl alicylate, and α-copaene. These compounds will be tested in the field to explore the development of a new chemical that is attractive to the borers and can be used in the management of the coffee berry borer H. hampei.

“…Dodecyloxybenzoic acid, 2,6,11,15-tetramethyl hexadecane, and longifolene merely existed in AF infested rice, and tetratetracontane and 3-octanone were only observed in ACL infested rice. Besides, longifolene was detected both in ACL and AF inoculated samples, and tridecane was discovered in all three mold-infected samples, demonstrating that tridecane, longifolene, and 3octanone might be present in small amounts in some fungi (Roman-Ruiz et al, 2012). On the third day of storage, the contents of decanal and 1-octanol in all fungal-infected rice samples decreased arrestingly to 30.42 μg g −1 FW, nevertheless the contents of nonanal and diethyl phthalate went up to 13.70-17.53 μg g −1 FW and 12.96-19.68 μg g −1 FW, respectively, which indicated that both of them may be likely to contribute to the odor characteristics of the samples.…”

Rice quality deterioration will cause grievous waste of stored grain and various food safety problems. Gas detection of volatile organic compounds (VOCs) produced by deterioration is a nondestructive detection method to judge rice quality and alleviate rice spoilage. This review discussed the research advance of VOCs detection in terms of nondestructive detection methods of rice quality deterioration, applications of VOCs in grain detection, inspection of characteristic gas produced during rice spoilage, rice deterioration prevention and control, and detection of VOCs released by rice mildew and insect attack. According to the main causes of rice quality deterioration and major sources of VOCs with off-odor generated during rice storage, deterioration can be divided into mold and insect infection. The results of literature manifested that researches mainly focused on the infection of Aspergillus in the mildew process and the attack of certain pests in recent years, thus the research scope was limited. In this paper, the gas detection methods combined with the chemometrics to qualitatively analyze the VOCs, as well as the correlation with the number of colonies and insects were further studied based on the common dominant strains during rice mildew, that is, Aspergillus and Penicillium fungi, and the common pests during storage, that is, Sitophilus oryzae and Rhyzopertha dominica. Furthermore, this paper pointed out that the quantitative determination of characteristic VOCs, the numeration relationship between VOCs and the degree of mildew and insect infestation, the further expansion of detection range, and the application of degraded rice should be the spotlight of future research.

BACKGROUND Chouioia cunea Yang (Hymenoptera: Eulophidae) is a parasitic wasp and natural enemy of several lepidopteran pests during their pupal stage. The volatiles from pupae of three hosts, Hyphantria cunea (Arctiidae), Antheraea pernyi (Saturniidae) and Lymantria dispar (Erebidae), were analyzed and compared to elucidate the chemical cues used by C. cunea to locate its hosts. RESULTS The attraction of C. cunea to H. cunea pupae has no obvious association with the types of plant leaves consumed by H. cunea before pupation. C. cunea exhibited the strongest attraction to the pupae of H. cunea, followed by those of A. pernyi and L. dispar based on behavioral experiments. Gas chromatography‐mass spectrometry and GC‐electroantennography (GC‐EAD) analyses showed that these three host pupae consisted of essentially the same active volatile components but at different relative amounts. Active components derived from these pupae by GC‐EAD were alkanes from C12 to C27, and C. cunea showed different levels of attraction to different single compounds. CONCLUSION Host location by C. cunea primarily depends on common compounds emanating from the pupae of several host species. The relative amount of each component varies across host species, guiding host preferences by C. cunea. Optimal blends of several components were identified. Understanding the chemical cues used by C. cunea to locate its host could increase the possibility of developing attractants for parasitic wasps and subsequently increasing the parasitism rate of C. cunea on various hosts. © 2019 Society of Chemical Industry
