    Genetic analysis of essential oil variants inPerilla frutescens (1995)
    Springer
    Biochemical genetics 33 (1995), S. 341-348 
    Details
    ISSN: 1573-4927
    Keywords: Perilla frutescens ; Labiatae ; chemotypes ; genetic analysis ; essential oils

    Notes: Abstract A new chemotype (C type) ofPerilla frutescens (Labiatae) that accumulatestrans-citral as a main component of the essential oil in the leaf was crossed with five other chemotypes containing perillaldehyde (PA), elsholtziaketone (EK), perillaketone (PK), perillene (PL), and phenylpropanoid (PP) as their respective major components for comparison of genetic differences. The analyses of F1 and F2 progenies showed thattrans-citral is accumulated when its metabolism is blocked in the simultaneous absence of a dominant geneN, which is involved in the conversion oftrans-citral into naginataketone viacis-citral, and two polymeric genesFr 1 andFr 2 , which are involved in the conversion oftrans-citral into perillene. On the basis of new data obtained from various intercrosses involving the C type as one of the parents, the genotypes of different chemotypes as well as the sites of action of several genes controlling reaction steps in the biosynthesis of monoterpenes inPerilla have been revised.

    Chemical nature of larval osmeterial secretions of papilionid butterflies in the generaParnassius, Sericinus andPachliopta (1995)
    Springer
    Journal of chemical ecology 21 (1995), S. 859-867 
    Details
    ISSN: 1573-1561
    Keywords: Osmeterial secretion ; Lepidoptera ; Papilionidae ; Parnassiinae ; Papilioninae ; Parnassius glacialis ; Sericinus montela ; Pachliopta aristolochiae ; aliphatic acid and ester ; monoterpene ; sesquiterpene

    Notes: Abstract Volatile components of the larval osmeterial secretion ofParnassius glacialis (Parnassiinae, Parnassiini) consisted of isobutyric acid, 2-methylbutyric acid, and their methyl esters. In contrast, the osmeterial exudate ofSericinus montela (Parnassiinae, Zerynthiini) was characterized as monoterpene hydrocarbons comprisingβ-myrcene (Major),α-pinene, sabinene, limonene, andβ-phellandrene, whereas that ofPachliopta aristolochiae (Papilioninae, Troidini) was composed of numerous sesquiterpene hydrocarbons, includingα-himachalene,α-amorphene, and germacrene-A, and a few oxygenated sesquiterpenoids. In these three species, the chemical nature of the secretions of the last and the penultimate instars was essentially of similar quality, suggesting that the three genera,Parnassius, Sericinus, andPachliopta, are assigned to homogeneous types.

    Chemical basis of differential oviposition by lepidopterous insects (1995)
    New York, NY [u.a.] : Wiley-Blackwell
    Archives of Insect Biochemistry and Physiology 30 (1995), S. 1-23

    ISSN: 0739-4462
    Keywords: Lepidoptera ; oviposition ; attractant ; repellent ; stimulant ; deterrent ; host-marking pheromone ; oviposition-deterring pheromone ; Chemistry ; Food Science, Agricultural, Medicinal and Pharmaceutical Chemistry

    Notes: Phytochemical mediators serving as attractants, repellents, stimulants, or deterrents in oviposition behavior of moths and butterflies are reviewed in regard to the chemical mechanism of host selection. Ovipositing females seem generally to utilize plant volatiles as cues for orientation to host plants, and the subsequent contact evaluation of plants by means of less- or non-volatile secondary metabolites is usually of great significance in host recognition. Most lepidopterans appear to be induced to oviposit in response to a single host-specific compound, while extreme synergism of multiple components features the stimulatory system of oviposition enacted by some butterflies. Recent investigations clearly demonstrate that acceptance or rejection of a particular plant by females is regulated not only by the presence or absence of oviposition stimulants but by negative stimuli evoked by co-occurring deterrents. The epideictic pheromones implicated in host assessment by females are also referred to in this review. © 1995 Wiley-Liss, Inc.
