Furthermore, it triggers physiological alterations like emission of volatile organic compounds or phytohormone levels in the plant. In our study, we assessed phytoplasma-induced changes in the phloem by sampling phloem sap from infected and non-infected apple plants. In infected plants, the soluble sugar content increased and the composition of phloem metabolites differed significantly between non-infected and infected plants. Sugar and sugar alcohol levels increased in diseased plants, while organic and amino acid content remained constant. As ‘Ca. P. mali’ is vectored by the phloem-feeding insect Cacopsylla picta (Foerster, 1848), we assessed whether the insect–plant interaction was affected by ‘Ca. P. mali’ infection of the common host plant Malus domestica Borkh. Binary-choice oviposition bioassays between infected and non-infected apple leaves revealed C.?picta’s preference for non-infected leaves. It is assumed and discussed that the changes in vector behavior are attributable to plant-mediated effects of the phytoplasma infection.","PeriodicalId":515,"journal":{"name":"Chemoecology","volume":"31 1","pages":"31 - 45"},"PeriodicalIF":1.8,"publicationDate":"2020-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00049-020-00326-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5030263","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}

Copper is an essential micronutrient for plants to survive, but at high concentrations (>?20?μg?g?1) in plant tissues, it can cause foliar chlorosis, stunted growth, and ultimately plant death. The Roseby Corridor in Central Queensland (near Cloncurry) is host to copper metallophytes (Polycarpaea spirostylis, Bulbostylis barbata, Tephrosia virens, Eriachne mucronata) which are able to tolerate soils with total copper concentrations up to 12,700?μg?g?1. Even with these high levels of copper in the rhizosphere, the maximum copper in all species is relatively low when compared to Cu concentrations in the soil (leaf/stem: Bulbostylis barbata: 40.9?μg?g?1, Eriachne mucronata: 12.3?μg?g?1, Polycarpaea spirostylis: 10.9?μg?g?1, Tephrosia virens: 128?μg?g?1).

Sex pheromones in the sex gland reached their highest quantity and influenced the expression of the PBP2 gene in male antennae. Furthermore, the expression of PBP genes was measured after mating and oviposition. The result showed that mating resulted in an increased expression of the PBP2 gene in male antennae, while the expression of the PBP1 gene increased in female antennae, indicating that PBP genes might play different functions in different sexes. Compared with females that had not mated, the PBP1 and PBP5 genes were up-regulated in female antennae after mating or oviposition.

These volatiles are reliable indicators of host presence when their emission in plants is induced by herbivory. Hyperparasitoids may also use information from lower trophic levels to locate their parasitoid hosts but little is known about the role of volatiles from the plant–host complex in the foraging behavior of hyperparasitoids. Here, we studied how Dendrocerus aphidum (Megaspilidae) responds to plant and host volatiles in a series of experiments. This hyperparasitoid uses aphid mummies as its host and hampers biological control of aphids by parasitoids in greenhouse horticulture. We found that D. aphidum females were strongly attracted to volatiles from mummy-infested sweet pepper plants, but only when clean air was offered as an alternative odor source in the Y-tube olfactometer. Hyperparasitoid females did not have a preference for mummy-infested plants when volatiles from aphid-infested or healthy pepper plants were presented as an alternative. These olfactory responses of D. aphidum were mostly independent of prior experience. Volatiles from the host itself were also highly attractive to D. aphidum, but again hyperparasitoid females only had a preference in the absence of plant volatiles. Our findings suggest that plant volatiles may confuse, rather than guide the foraging behavior of D. aphidum. Mummy hyperparasitoids, such as D. aphidum, can use a wide variety of mummies and are thus extreme generalists at the lower trophic levels, which may explain the limited role of (induced) plant volatiles in their host searching behavior.","PeriodicalId":515,"journal":{"name":"Chemoecology","volume":"30 6","pages":"315 - 325"},"PeriodicalIF":1.8,"publicationDate":"2020-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00049-020-00321-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4963486","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}

An emerging understanding of non-canonical reactions (reactions which occur independently of canonical reactions) suggests that the physical chemistry of compounds may play a larger role in constraining chemo-diversity than previously thought. We selected 24 studies of plant volatile profiles, satisfying a defined set of criteria, to assess the extent of correlation among profiles attributable to either shared biosynthetic enzymes or physiochemical properties. Across studies, regardless of treatment, 0.17 (±?0.16 SD) adjusted R2 was attributed to both shared biosynthetic enzymes and physiochemical properties; however, there were no significant differences between the amount of unique variance attributed to shared enzymes (0.05?±?0.08 SD) or physiochemical properties (0.03?±?0.06 SD).

Bactrocera frauenfeldi is known to respond to the phenylbutanoids raspberry ketone (RK) and cue lure (CL), anisyl acetone (AA), and zingerone (ZN), which are produced by some rainforest orchids. Here we compared the relative field responses of B. frauenfeldi males to these phenylbutanoids in two selected locations to determine the most attractive lure for this species. We also performed gas chromatographic-mass spectral analyses of male rectal pheromone glands to understand the fate of the ingested compounds. Results showed that B. frauenfeldi males were most responsive to CL, equally to RK and AA, while poorly to ZN in Cairns, a site with high population density. No significant difference was observed in Lockhart River which has a low population density of B. frauenfeldi. Chemical analyses showed that most of the ingested phenylbutanoids were sequestered into rectal glands, either unchanged or with minimal structural changes except for AA, which is converted to RK via a demethylation of the methoxy- to a hydroxy-moiety and reduced to 4-(4-methoxyphenyl)-2-butanol via the keto-moiety. This study provides both practical and ecological implications: it identified the most attractive lure, which is important for monitoring and management of B. frauenfeldi; and based on the relative responses, conversion and retention rates by B. frauenfeldi males, revealed the ecological significance of these phytochemical lures in plant-fruit fly co-evolution.","PeriodicalId":515,"journal":{"name":"Chemoecology","volume":"30 6","pages":"305 - 314"},"PeriodicalIF":1.8,"publicationDate":"2020-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00049-020-00320-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4935054","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}

To further investigate the specificity of the responses of Cardiophorus males, additional analogs with different chain lengths and structural relationships compared to the natural pheromone were synthesized and tested. In field and electroantennogram bioassays, only fuscumol propionate ((E)-6,10-dimethylundeca-5,9-dien-2-yl propionate) elicited strong responses from Cardiophorus males, indicating that they were able to distinguish chain length and spatial relationships between the structural elements. In field trials, C. tenebrosus males were attracted equally to the analog and their natural pheromone, but the pheromone elicited stronger antennal responses from males. In contrast, traps baited with fuscumol propionate caught approximately 26 times as many C. edwardsi males compared to traps baited with the natural pheromone, although the analog elicited significantly smaller antennal responses from C. edwardsi males.

After attaining reproductive competence, they switch their search and respond to a small, fresh carcass to prepare for their brood. Because the cues used to locate a feeding versus a breeding resource both originate from carrion, the beetles must respond to subtle changes in volatiles during decomposition. We investigated cues used to locate a fresh carcass in the field by (1) a general subtractive method, applying an antibacterial or antifungal compound to reduce microbially derived volatiles, and (2) a specific additive method, placing chemical supplements near a fresh carcass. Five sulfur-containing compounds, known to result from bacterial metabolism of sulfur-containing amino acids, were studied: dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), methyl thiolacetate (MeSAc, also known as S-methyl thioacetate), and methyl thiocyanate (MeSCN). When a carcass aged for 48?h was treated with an antibacterial compound to reduce volatiles, there was a 59% decrease in beetles discovering the resource. The addition of the chemical supplement MeSAc had no effect on discovery of a fresh carcass, while DMS and DMDS had a limited ability to attract breeding beetles. The chemical that was least well known, MeSCN, increased beetle numbers by 200–800% on a fresh carcass and almost guaranteed discovery. DMTS, which is known to attract a variety of carrion insects, was the only compound to significantly reduce beetle presence at a fresh carcass. A laboratory experiment demonstrated that DMTS does not directly inhibit breeding, suggesting that DMTS deters breeding beetles while they fly.","PeriodicalId":515,"journal":{"name":"Chemoecology","volume":"30 6","pages":"287 - 296"},"PeriodicalIF":1.8,"publicationDate":"2020-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00049-020-00318-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5050323","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}
