Semiochemicals may provide feasible targets to develop sensitive detection and monitoring tools. Therefore, this study aimed to evaluate whether S. mangiferae use pheromones from conspecifics and kairomones from mango tree host in their chemical communication. The findings identify a blend of mango volatiles that influence the behaviour of S. mangiferae females. A synthetic blend containing the EAD-active compounds γ-butyrolactone, benzaldehyde, 6-methyl-5-hepten-2-one, myrcene, (Z)-ocimene, 2-methoxyphenol, (S)-linalool, methyl salicylate and methyl benzoate was attractive to females of S. mangiferae from Ghanaian and Brazilian populations in two-choice olfactometry experiments. The results also indicate that the absolute configuration of linalool in the mango synthetic blend is crucial for female attraction, as females respond only to blends containing (S)-linalool. Furthermore, females from both populations were attracted to the odour of live males from their respective localities. Chemical analysis of aeration samples from the Brazilian population revealed that males and females emitted qualitatively similar volatile profiles. Although no male-specific compounds could be identified to fully explain female attraction, this study provides the first evidence of intraspecific chemical communication in S. mangiferae.

Heather beetle Lochmaea suturalis (Coleoptera: Chrysomelidae), introduced from the United Kingdom (UK) to New Zealand (NZ) to control the invasive shrub Calluna vulgaris (heather), was difficult to establish and achieved poor population growth rates and expansion relative to its conspecifics in its native UK range. Poor performance in biocontrol is often attributed to various abiotic or biotic factors but seldom considers alterations to a target plants biochemical phenotype. A recent study revealed, heather has a significantly different biochemical profile in NZ compared with the UK, between which there is considerable difference in ultra-violet (UV) radiation. UV is known to drive plant biochemical change, including defensive secondary metabolites and we hypothesized that this factor could enhance heathers’ defensive capability leading to poor biocontrol agent performance. Testing this hypothesis involved exposing heather plants to 20% and 95% UV attenuating screens and using metabolomics to measure plant secondary metabolite responses. Our results demonstrate significant alterations to many compounds derived from the shikimate-phenylpropanoid pathway. However, a bioassay revealed no impact on prepupal weight or larval survival of the biocontrol agent L. suturalis.

Behavioural bioassays were used to quantify male copulatory responses, including time to first contact, number of contacts, aedeagus display, time to commence mating, and copulation duration. Visual cues were tested using chemically neutral dummy beetles, while chemical cues were assessed using female cuticular hydrocarbon (CHC) extracts. Combined cue effects were evaluated by exposing males to live and freeze-killed females of different mating status. Visual cues alone elicited rapid contact and aedeagus display, indicating initiation of mating attempts. Chemical cues also influenced male behaviour, with males spending significantly more time on CHC-treated surfaces than on solvent controls. When cues were combined, males-initiated mating more quickly and copulated for longer with live females than with dead females, irrespective of female mating history. GC–MS analysis revealed clear differences in CHC profiles between sexes and between mated and unmated individuals. Overall, these results show that while single cues can trigger early mating responses, effective and sustained mating in C. sexmaculata depends on the integration of multiple sensory cues.

VOCs can attract insects over relatively long distances, whereas SVOCs tend to remain on trap surfaces, where they may influence local interactions with arthropods and microbes. Environmental conditions, particularly precipitation and humidity, are known to affect VOC emissions and may alter foraging dynamics, yet the extent to which variation in chemical emissions corresponds with differences in prey capture is still not well resolved. To address this knowledge gap, we performed a study under both field and greenhouse conditions using the carnivorous plant Drosera rotundifolia in two climatically contrasting sites of north-western Spain: the wetter Serra do Cando (CP) and the drier Serra de Ancares (AP). At both sites, we quantified insect prey capture and characterized VOC and SVOC emissions. Prey capture rates were similar between regions, but plants from the drier site showed higher total VOC emissions, while SVOC production did not differ markedly.

S. dorsalis relies on both visual and olfactory cues to locate and recognize its host plants and exhibits preference for young foliage. However, little is known about the specific cues mediating host selection by S. dorsalis. The objectives of this study were to: (1) identify herbivore-induced plant volatiles (HIPVs) produced by strawberry plants in response to S. dorsalis infestation versus mechanical damage; and (2) assess the behavioral response of S. dorsalis to uninfested versus infested strawberry plants. Laboratory olfactometer experiments revealed that S. dorsalis preferentially oriented to the volatiles from uninfested strawberry plants over those released by plants infested with conspecifics. In addition to the observed preference of S. dorsalis for uninfested strawberry plants, gas chromatographic-mass spectrometry revealed significant differences between the volatile compounds produced by uninfested strawberry plants and those produced by plants that had been infested with S. dorsalis in both the 'Florida Brilliance' and 'Florida Sensation' cultivars. Seventeen volatiles were identified from strawberry plants that were released in response to either mechanical or S. dorsalis feeding-induced damage; however, only three [(Z)-3-hexenyl acetate, cymene, and α-farnesene] were significantly elevated in S. dorsalis-infested plants relative to undamaged plants. One of these HIPVs, (Z)-3-hexenyl acetate, eliminated natural attraction of S. dorsalis to uninfested strawberry even though it did not act as a repellent when presented alone. Our results suggest a possible practical application of semiochemicals for managing S. dorsalis in strawberry.</p>","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"52 2","pages":"19"},"PeriodicalIF":2.1,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12920741/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146226734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
