1,3,5,7-Tetramethyldecyl formate, lardolure: Aggregation pheromone of the acarid mite, Lardoglyphus konoi (sasa et asanuma) (Acarina: Acaridae).

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...

Identification 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...

Allergological characterisation of the storage mite Acarus gracilis (Acari: Acaridae).

BACKGROUND Storage mites of the genus Acarus can be responsible for allergic sensitisation in domestic environments. Acarus gracilis is a frequent species in some geographical regions of the Iberian Peninsula. Since the allergenicity of this mite has not been described before, the objectives of this study were to characterise it immunologically, and to compare it with the closely related and mo...

A new species of chigger mite, Hannemania hegeneri (Acarina; Trombiculidae).

Functional response of the predatory mite Chileseius camposi (Acarina: Phytoseiidae) on densities of it prey, Panonychus ulmi (Acarina: Tetranychidae).

The functional response of the phytoseiid predator Chileseius camposi González y Schuster, 1962 (Acarina:Phytoseiidae) on densities of its prey Panonychus ulmi (Koch, 1836) was evaluated under controlled temperature (20 +/- 2 degrees C), relative humidity (75 +/- 15%) and photoperiod (16:8h L:D). A functional type II response was displayed (Holling's disk). Holling, Wolf transformation and Roge...
