In mainland Japan, adult females preferentially lay eggs on Albizia julibrissin and Lespedeza cuneata. In the field, females may oviposit on non-fabaceous plants, although rarely. When maintained in our laboratory with their natural hosts removed, females showed moderate oviposition responses to Oxalis corniculata (Oxalidaceae), but newly hatched larvae failed to grow to the second instar on the leaves. This indicated that females made oviposition mistakes on O. corniculata because it is not suitable for larval development. We attempted to identify the phytochemicals that regulate oviposition of E. mandarina on O. corniculata. Females hardly responded to the methanolic leaf extract and its aqueous fraction but responded weakly to the most polar subfraction. Further fractionation of this subfraction by ion-exchange column chromatography revealed high oviposition-eliciting activity in the acidic subfraction and low activity in the acidic/neutral/amphoteric and neutral/amphoteric subfractions. Mass spectrometry and oviposition bioassays identified erythronic and threonic acids as stimulants in the acidic subfraction, and arabinose and arabitol as deterrents in the neutral/amphoteric subfraction. Leaf samples of O. corniculata varied greatly in the composition of the four components; however, none contained the concentration of stimulants necessary to induce oviposition without being counteracted by deterrents. These results suggest that oviposition mistakes on O. corniculata, though infrequently, occur when females discover non-hosts with sufficiently high concentrations of stimulants and sufficiently low concentrations of deterrents.</p>","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 1","pages":"9"},"PeriodicalIF":2.2,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143033336","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}

We tested whether the carbon chain length in (Z)-3-fatty alcohols with four to nine carbons and the double bonds in six-carbon alcohols contribute to bioactivity. In Solanum peruvianum suspension-cultured cells we found that (Z)-3-fatty alcohols, except (Z)-3-butenol, induce medium alkalinization and MAP kinase phosphorylation, two signaling responses often tied to the perception of molecular patterns that function in plant immunity and resistance to herbivores. In tomato (S. lycopersicum) seedlings, we found that (Z)-3-fatty alcohols induce inhibition of root growth. In both signaling and physiological responses, (Z)-3-octenol and (Z)-3-nonenol had a higher bioactivity than (Z)-3-heptenol and (Z)-3-hexenol, with (Z)-3-butenol only being active in root growth assays. Bioactivity correlated not only with chain length but also with lipophilicity of the fatty alcohols. The natural GLVs (E)-2-hexenol and the saturated 1-hexanol exhibited a higher bioactivity in pH assays than (Z)-3-hexenol, indicating that the presence and position of a double bond also contributes to bioactivity.

We tested relationships between the pollen composition and the insect visitation matrix as well as an insect trait matrix including sociality, body size, nesting behavior, and whether the insect was a bee or hoverfly. We found: (i) the agrochemical treatments did not affect the biochemical composition of the pollen; (ii) there were many strong associations between fatty acids, amino acids, insect traits, and visitation; and (iii) specific compounds with strong associations (montanic acid, cysteine, and proline) explained more of the variance in insect abundance (honeybees, bumble bees, and hoverflies) than the total amino acid or fatty acid concentrations in the pollen.

Despite the fact that Z and M flies produce different amounts of cuticular pheromones, their manipulation and that of other sensory signals exchanged during courtship behavior only marginally rescued the behavioral isolation. To further explore the putative mechanisms involved in this phenomenon, we first assessed the fecundity in matings between Z and M flies. Then, we measured the reproduction and survival in adults resulting of co-cultured Z and M larvae. In these two experiments, Z flies rarely emerged. Z and M larvae produced different amounts of food-derived metabolites which were altered in co-culture condition. This maybe related to the different bacteria composition in the gut and body of Z and M flies. However, the mating behavior of co-cultured flies did not change and their cuticular pheromone profile was slightly altered.

The kōwhai moth, Uresiphita polygonalis maorialis, a native crambid, is known for its herbivory on Sophora spp. and Lupinus arboreus leaves. Understanding the chemical ecology of this species is essential for studying its behavior, population dynamics, and ecological interactions. In this study, the female sex pheromone of U. polygonalis maorialis was analyzed using coupled gas chromatography-electroantennogram detection (GC-EAD). This approach identified four antennally active compounds in the female gland extracts. Subsequent gas chromatography-mass spectrometry (GC-MS) and chemical derivatization revealed these compounds to be tetradecyl acetate (14:Ac), (E)-11-tetradecenyl acetate (E11-14:Ac), (Z)-11-tetradecenyl acetate (Z11-14:Ac), and (Z)-11-hexadecenyl acetate (Z11-16:Ac). Field trapping experiments evaluated various combinations of these four EAD-active compounds and (E)-11-hexadecenyl acetate (E11-16:Ac). Results indicated that traps baited with blends containing E11-14:Ac, Z11-14:Ac, and Z11-16:Ac captured significantly more males compared to unbaited delta traps. A blend ratio of 144:84:72 µg (E11-14:Ac: Z11-14:Ac: Z11-16:Ac) proved the most effective, capturing the highest number of males. Male captures were recorded from late November to late February, peaking in late December, suggesting a univoltine population in Canterbury. Among the three tested doses, the 300 µg and 1000 µg doses of the three-component blend were the most effective. The identification of the sex pheromone components of U. polygonalis maorialis provides a valuable tool for monitoring this species, contributing to a deeper understanding of its population densities and distribution within its native range. It also offers insights into the evolutionary development of pheromone communication within the genus, shedding light on species divergence and adaptation.</p>","PeriodicalId":15346,"journal":{"name":"Journal of Chemical Ecology","volume":"51 1","pages":"4"},"PeriodicalIF":2.2,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11754372/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143023560","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}

This is because males of both species of fruit flies are attracted to, and feed on a phenylpropanoid compound, methyl eugenol (ME). Although CP was a more potent attractant than ME for B. correcta, it is not known if males of B. dorsalis are also attracted to CP. The possible attraction of B. dorsalis to CP as a sesquiterpene may indicate its wide host range through its attraction to different groups of plant volatiles i.e., phenylpropanoids and sesquiterpenes. In this paper, we report that males of B. dorsalis were also attracted to, and feed on CP. Subsequently, we conducted a probit regression analysis to determine the quantal response of sexually mature male flies that were attracted to CP in cage bioassays. Therefore, as a measure of male B. dorsalis' sensitivity of CP, the median dose of CP required to elicit a positive response in 50% of the tested B. dorsalis population (ED₅₀) was calculated as 3.7 mg.
