Stereochemistry of female-specific normonoterpenes, sex pheromone candidates from the acarid mite, Tyreophagus sp. (Astigmata: Acaridae).
Two normonoterpenes were detected from an unidentified Tyreophagus sp. as new female-specific components. Both planar structures were identified to be 2,6-dimethyl-5-heptenal (1) and 2,6-dimethyl-5-hepten-1-ol (2) by GC/MS co-chromatography with synthetic 1 and 2. The stereochemistry of 2 was determined to be R by a GC analysis with a chiral column, while that of 1 was presumed to be similar to...
متن کاملIdentification and Synthesis of (Z,Z)-8,11-Heptadecadienyl Formate and (Z)-8-Heptadecenyl Formate: Unsaturated Aliphatic Formates Found in the Unidentified Astigmatid Mite, Sancassania sp. Sasagawa (Acari: Acaridae).
We identified two aliphatic formates, (Z,Z)-8,11-heptadecadienyl formate and (Z)-8-heptadecenyl formate in the opisthonotal gland secretions of an unidentified acarid species, namely Sancassania sp. Sasagawa. Both compounds were isolated using silica gel column chromatography and the structures were elucidated by ¹H-NMR and GC/FT-IR. Further information on the double bond positions was obtained...
متن کاملBiological Responses of Atta texana to Its Alarm Pheromone and the Enantiomer of the Pheromone.
S-(+)-4-Methyl-3-heptanone is the principal alarm pheromone of Atta texana. The dextrorotatory form of the ketone has also been identified from Atta cephalotes. Both enantiomers have been synthesized in high optical purity; Atta texana is more responsive to the (+) enantiomer than to the (-) form. These results implicate a chiral receptor system.
متن کاملPopulations of Stored Product Mite Tyrophagus putrescentiae Differ in Their Bacterial Communities
BACKGROUND Tyrophagus putrescentiae colonizes different human-related habitats and feeds on various post-harvest foods. The microbiota acquired by these mites can influence the nutritional plasticity in different populations. We compared the bacterial communities of five populations of T. putrescentiae and one mixed population of T. putrescentiae and T. fanetzhangorum collected from different h...
متن کاملChemoenzymatic synthesis of the alarm pheromone (+)-verbenone from geranyl diphosphatew
With more than 30 000 known members, terpenoids constitute the largest and most structurally diverse family of natural products. Monoterpenes are often found in natural, renewable extracts such as turpentine and are a source of commercially valuable synthetic fragrances, flavours, drugs, agrochemicals and synthetic building blocks. Plant derived terpenoids have diverse biological functions in c...
