Intercropping soybean with sorghum is suggested as a strategy to reduce the abundance of P. japonica throughout soybean fields. The mechanism by which this affects P. japonica is unknown but may arise from a difference in the host plant compounds emitted by the intercropped plants because P. japonica responds to olfactory cues. In this study, we investigated a semiochemical-based mechanism for the behavioral response of P. japonica to intercropping soybean with sorghum by (1) evaluating P. japonica behavioral responses to solvent extracts from monocropped soy, intercropped soy, and a mixture of soy and sorghum extracts in no-choice video-tracking and preference in a release-recapture dual-choice assay to host stimuli from plants; and (2) applying solid-phase microextraction (SPME) in conjunction with gas chromatography coupled with mass spectrometry (GC-MS) to characterize the semiochemical profiles of each extract. We found unique semiochemical profiles among our treatments, with 1-octen-3-ol and 1-octanol characteristic of monocropped soybean and dodecane-1-iodo primarily in sorghum extracts. Nevertheless, our treatments did not significantly affect movement or orientation by P. japonica compared to controls, nor did conspecifics exhibit a significant preference for any of the treatments in a dual-choice assay at a local scale. Therefore, if intercropping soybean with sorghum significantly affects the behavior of P. japonica in the field, it may occur at a different scale, or in response to non-olfactory stimuli (e.g., visual, habitat, or landscape cues) rather than semiochemical cues.</p>","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"52 4","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148387582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In eusocial insects like ants, where species boundaries are often maintained through chemical rather than morphological differentiation, integrative methodologies are essential for resolving taxonomic complexity. Here, we present compelling evidence for the recent divergence of African carpenter ants initially identified as Camponotus maculatus into two distinct sub-populations. This divergence is supported through an integrative approach combining chemical, behavioral, and genetic analyses. Most strikingly, we identify two sharply contrasting chemotypes characterized by categorically different cuticular hydrocarbon (CHC) profiles that unambiguously separate the investigated ant populations. Concordantly, behavioral assays reveal that worker ants consistently exhibit aggression toward individuals with opposing chemotypes, while displaying affiliative behaviors toward shared chemotypes irrespective of colony affiliation. Genetic barcoding further corroborates these findings, indicated by phylogenetic clusters largely corresponding with the two chemotypes. Our results highlight the primary role of chemical differentiation within morphologically indistinguishable populations to resolve cryptic sub-population structures.

Although this hypothesis has been examined for smaller mammalian hindgut-fermenters, less is known about responses to PSM mixtures in wild ruminants. To assess the role of host and microbial responses to PSM composition, we used controlled feeding trials to measure voluntary dry matter and PSM intake, urinary excretion of glucuronic acid (GA, a byproduct of PSM detoxification through conjugation), and the diversity and relative abundance of gastrointestinal bacterial families in the feces of two species of captive-raised deer (Odocoileus hemionus, O. virginianus). Deer were fed five mixtures of four purified PSMs that included two same-chemical class mixtures, two different-class mixtures, and one 4-way mixture of all chemicals. Overall, we found that PSM composition had minimal effect on intake, that GA was a consistent physiological biomarker of PSM intake regardless of PSM composition, and that dietary phenolics may influence microbial communities more than monoterpenes. Our results partially conformed to the detoxification limitation hypothesis, where deer consumed less of one same-class mixture (monoterpenes) than different-class mixtures.

Here, we elucidate the endogenously produced and ME-derived chemical signals involved in the species' communication. Gas chromatography-mass spectrometry analyses of pheromonal glands revealed that immature males produced four endogenous compounds, whereas sexually mature males produced six additional volatile compounds, including the terpenoids (R)-6-methyl-2-vinylhept-5-ene-1,2-diol and (S)-7-methyl-3-methyleneoct-6-ene-1,2-diol, which, to our knowledge, have not previously been documented in insects.

Behavioral assays using a Y-tube olfactometer demonstrated that two endogenous compounds (3-ethyl-2,5-dimethylpyrazine and 6-oxo-1-nonanol) and two ME metabolites (DMP and E-CF) significantly attracted virgin females during courtship. In contrast, none of the endogenous volatiles was attractive to the males, whereas three ME metabolites-eugenol, isoeugenol, and DMP-elicited significant male attraction during dusk. These findings demonstrated that B. umbrosa utilizes endogenous compounds as sex-specific signals to attract conspecific females, while distinct ME-derived metabolites mediate both male-male and male-female communication, facilitating male aggregation and enhancing sexual attraction.

To examine the relationship between herbivory and protection against Chl phototoxicity, we investigated larvae of the leaf beetle Chlamisus laticollis, which feed on Rhododendron leaves and construct a faecal case. When the faecal case was removed from C. laticollis larvae, strong light exposure reduced larval survival and growth. Although the effect was independent of light wavelength (red 655 nm, green 530 nm, blue 470 nm), some case-removed larvae lost weight under blue light, suggesting a partial negative effect of blue light on their growth. Leaf Chls ingested by larvae appeared to be rapidly dissociated from photosystems but possibly associated with some components that limit photoexcitation. Although ingested Chls were gradually degraded to phototoxic catabolites in larvae, lipid peroxide levels, indicating ROS production, were unaffected by the presence of the case, the amount of Chl catabolites, or blue light exposure. Our results suggest that although C. laticollis larvae are shielded from sunlight by their faecal case, they retain intrinsic mechanisms that attenuate Chl phototoxicity.
