(Z)-10-heptadecen-2-one and 2-tridecanone biosynthesis from [1-14C]acetate by Drosophila buzzatii

Insect Biochemistry and Molecular Biology, 1993
Abstract The in vitro incorporation of [1- 14 C]acetate into (Z)-10-heptadecen-2-one, the major aggregation pheromone component of D. buzzatii , was greatest in the microsomal fraction of ejaculatory bulbs from mature male D. buzzatii . [1- 14 C]Acetate was also incorporated into 2-tridecanone, an ejaculatory bulb component that inhibits the ...

Inhibition ofCampoletis sonorensis parasitism ofHeliothis zea and of parasitoid development by 2-tridecanone-mediated insect resistance of wild tomato

Journal of Chemical Ecology, 1989
Field populations ofHeliothis spp. were sampled for levels of naturally occurring larval parasitism on six tomato lines varying in levels of 2-tridecanone-mediated resistance toManduca sexta (L.) andLeptinotarsa decemlineata (Say). Second and third instars were parasitized byCampoletis sonorensis (Cameron) (Hymenoptera: Ichneumonidae) andCotesia ...

Eclipta indica L.(Asteraceae): A source of 2-Tridecanone

Journal of Essential Oil Research, 2007
Abstract The volatile oil obtained by hydrodistillation from the leaf of Eclipta indica L. was analyzed for its constituents by means of GC and GC/MS. 2-Tridecanone (89.7%), a straight chain ketone, was the singly most abundant constituent. Caryophyllene oxide (3.9%) and β-caryophyllene (2.6%) were the other compounds occurring in sizeable proportions.

RIFM fragrance ingredient safety assessment, 2-tridecanone, CAS Registry Number 593-08-8

Food and Chemical Toxicology, 2022
The existing information supports the use of this material as described in this safety assessment. 2-Tridecanone was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, photoirritation/photoallergenicity, skin sensitization, and environmental safety.

Role for Transferrin in Triggering Apoptosis in Helicoverpa armigera Cells Treated with 2-Tridecanone

Journal of Agricultural and Food Chemistry, 2018
2-Tridecanone, a plant allelochemical present in a large range of tomato species ( Lycopersicon hirsutum f. glabratum), can induce the expression of Helicoverpa armigera transferrin ( HaTrf), which is necessary for insect growth and development. To gain further insight into the mechanism of HaTrf in response to 2-tridecanone, we measured the iron and ...

2-Undecanone and 2-tridecanone in field-grown onion

Journal of Environmental Science and Health, Part B, 2013
A field study was conducted to investigate the impact of soil amendments on concentrations of two volatile organic compounds, 2-undecanone and 2-tridecanone, in onion bulbs. The soil in five plots was mixed with sewage sludge, five plots were mixed with yard waste compost, five plots were mixed with laying hen manure each at 15 t acre(-1), and five ...

Accumulation and turnover of 2-tridecanone in Tetranychus urticae and its consequences for resistance of wild and cultivated tomatoes

Experimental & Applied Acarology, 1999
In this study we assessed the dynamic changes of 2-tridecanone in a herbivorous mite (Tetranychus urticae) on tomato (Lycopersicon esculentum, cv. 'Moneymaker'), a plant with methyl ketones in the tetracellular tips of the glandular trichomes (Type VI). We showed that spider mites accumulate 2-tridecanone when foraging on cultivated tomato.

Resistance to 2-tridecanone in Tetranychus urticae: effects of induced resistance, cross-resistance and heritability

Experimental & Applied Acarology, 2001
Earlier studies of resistance to the tomato toxin 2-tridecanone revealed similar levels of resistance among tomato and cucumber strains of Tetranychus urticae, whereas we anticipated the tomato strains to have a higher resistance. Between-strain differences, however, may be concealed by toxin accumulation and/or cross-resistance.

Source of oxygen in the conversion of 2-tridecanone to undecyl acetate by Pseudomonas cepacia and Nocardia sp.

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1974
Abstract Cell-free extracts from Pseudomonas cepacia and Nocardia sp. when supplied with NADPH accumulated undecyl acetate from 2-tridecanone in the presence of an esterase inhibitor, tetraethyl pyrophosphate. Mass spectra of undecyl acetate formed in an 16O2-atmosphere exhibited characteristic oxygencontaining ions of m/e 61, 73, and 116.
