Soy sauce, renowned for its distinctive taste and aroma, has become one of the most popular condiments worldwide. However, its odor attracts the flesh fly Parasarcophaga dux for larviposition, posing a threat to product quality and safety. Here, gas chromatography-ion mobility spectrometry (GC-IMS) was employed to analyze the differential volatile compounds in nine types of soy sauce with varying degrees of attractiveness to P. dux . Notably, 12 differential volatile compounds elicited antennal responses. Furthermore, olfactometer bioassays revealed 6 of them induced behavioral reaction. 3-hydroxy-2-butanone, 2-propanol, butanal, and 2-methylpyrazine were attractive to female flies, while β-myrcene and δ-octalactone exhibited repellent effects. These findings suggest that key volatile compounds with attractive or repellent properties may regulate the differential preference of P. dux for various soy sauces. This study provides a theoretical foundation for preventing P. dux larviposition in soy sauce through formula adjustment and supports the development of the soy sauce industry.

BACKGROUND Harmonia axyridis Pallas (Coleoptera: Coccinellidae) is an important natural enemy of aphids. Plant species and plant health conditions can affect the behavior of H. axyridis . To determine plant effects on this lady beetle, we examined beetle responses to four cover crops: coriander ( Coriadrum sativum L., Apiales: Apiaceae), marigold ( Tagetes erecta L., Asterales: Asteraceae), sweet alyssum ( Lobularia maritima L., Brassicales: Brassicaceae), and alfalfa ( Medicago sativa L . , Fabales: Fabaceae). Our goal was to better understand this predator's ovipositional behavior in response to different plants and its olfactory response to the aphid-induced volatiles from these plants. RESULTS We found that this lady beetle did not have any significant oviposition preference among the four plant species, but H. axyridis preferred to lay eggs on the lower surface of leaves, regardless of the plant species. H. axyridis females had a significant preference for aphid-infested marigolds, but were not attracted by any of the other three cover plants or marigolds without aphid damage. Compared to the uninfested marigold plants, the emission of 12 compounds significantly increased on the aphid-infested marigolds, and two of them were attractive to H. axyridis under suitable concentrations. CONCLUSION H. axyridis did not show any significant oviposition preference among the four cover crops. Aphid-infested marigolds can attract H. axyridis . Indole and terpinen-4-ol mediated lady beetle attraction. These synomones have potential for manipulating populations of H. axyridis as a component of conservation biological control. © 2022 Society of Chemical Industry.

BACKGROUND Grapholita molesta is an important pest of rosaceous fruit trees. Female oviposition affects larval infestation levels in orchards. This behavior, shaped by larval feeding experiences and female olfactory responses, points to an experience-modulated semiochemical strategy based on host plant secondary metabolites. To elucidate the combined effects of non-volatile and volatile components on female oviposition, we analyzed the volatile profiles of peach, pear, and apple shoots/fruits under intact, mechanically injured, and larval damage states throughout the growing season, along with female oviposition preferences, and compared olfactory responses (electroantennogram (EAG) and wind-tunnel experiments) and oviposition bioassays with benzaldehyde (amygdalin hydrolysate) between females with two larval amygdalin-feeding experiences. RESULTS Female oviposition preference and benzaldehyde emissions, both modulated by host factors, exhibited synchronous fluctuations. In EAG and wind-tunnel experiments, females not fed amygdalin during larval stages exhibited a strong attraction to benzaldehyde at concentrations of 10 and 0.1 μg/μL; however, females from larvae fed amygdalin showed a weaker long-distance orientation but greater responses to benzaldehyde during close-range approach and landing behaviors. Females fed amygdalin during larval stages were more likely to be responsive to lower concentrations of benzaldehyde (0.01, 0.1, and 1.0 μg/μL) for oviposition. In contrast, close-range attraction and oviposition behaviors were stronger for females that developed from amygdalin-fed larvae than those that were not fed amygdalin. CONCLUSION Dietary exposure to amygdalin during the larval stages increased the olfactory responses of females to benzaldehyde. Female oviposition behavior is co-regulated by larval experience derived from amygdalin ingestion and benzaldehyde as a host semiochemical signal. © 2025 Society of Chemical Industry.
