Gas chromatographic–mass spectrometric analyses of whole body extracts of Oribotritia berlesei, a large-sized soil-dwelling oribatid mite, revealed a consistent chemical pattern of ten components, probably originating from the well-developed opisthonotal glands. The three major components of the extract were the iridoid monoterpene, (3S,8S)-chrysomelidial (about 45% of the extract), the unsaturated hydrocarbon 6,9-heptadecadiene, and the diterpene β-springene (the latter two, each about 20–25…

Discrimination of Oribotritia species by oil gland chemistry (Acari, Oribatida)
TLDR
The chemical composition of secretions from opisthonotal (oil) glands in four species of the oribatid mite genus Oribotritia was compared by means of gas chromatography—mass spectrometry and indicated the classification of euphthiracaroids within the (monophyletic) group of “Astigmata compounds-bearing”-Oribatida.
Oil gland secretions in Oribatida (Acari)
TLDR
Pheromonal properties of oil gland compounds probably evolved early in ancient oil gland-bearing oribatids from purely defensive functions, culminating in a radiation of semiochemical roles (alarm, aggregation, sex) in oil glands of the Astigmata.
The Absolute Configuration of Chrysomelidial: A Widely Distributed Defensive Component Among Oribotririid Mites (Acari: Oribatida)
The absolute configuration of the iridoid monoterpene chrysomelidial from the oribatid mite, Austrotritia dentate Aoki, was elucidated by the GC-MS and GC comparisons with four synthetic…
The ontogeny of oil gland chemistry in the oribatid mite Archegozetes longisetosus Aoki (Oribatida, Trhypochthoniidae)
TLDR
It is shown that absolute and body mass-corrected amounts of oil gland secretions increase during ontogeny and that secretion quantity scales allometrically with body mass (i.e. ontogenetic instar).
Taxonomic distribution of defensive alkaloids in Nearctic oribatid mites (Acari, Oribatida)
TLDR
The findings are consistent with a generalization that alkaloid presence is widespread, but not universal in Oripodoidea, and all sampled species of the cosmopolitan oripodoid families Scheloribatidae and Parakalummidae, and the related, mostly tropical families Mochlozetidae and Drymobatidae contain alkaloids.
Chemical basis of unwettability in Liacaridae (Acari, Oribatida): specific variations of a cuticular acid/ester-based system
TLDR
A comparative study on the chemistry of cuticular lipid layers in a selection of Liacaridae, including representatives of all major Central European genera, Liacarus, Dorycranosus, Adoristes, and Xenillus is conducted, providing first insights into the comparative chemistry of the inner (=lipid) layer of the oribatid cerotegument.
Beetles Do It Differently: Two Stereodivergent Cyclisation Modes in Iridoid‐Producing Leaf‐Beetle Larvae
TLDR
Differences in the cyclisation of the ultimate precursor 8‐oxogeranial (8) to 1, between members of the genus Gastrophysa and all other species are revealed.
A cytochrome P450 from the mustard leaf beetles hydroxylates geraniol, a key step in iridoid biosynthesis.
Life as a fortress – structure, function, and adaptive values of morphological and chemical defense in the oribatid mite Euphthiracarus reticulatus (Actinotrichida)
TLDR
Such an effective, holistic defense strategy, involving both morphological and chemical traits, probably carries high resource-costs, but it allows adult euphthiracaroid mites to occupy an almost “enemy-free space” despite the high diversity of predators in soil.
Chemical Polymorphism in Defense Secretions during Ontogenetic Development of the Millipede Niponia nodulosa
TLDR
As the cuticle hardens in older juveniles (5th, 6th, 7th instars) and adults, this allows for a switch in defense to using less effective and less costly volatile organic compounds (presumably microbial in origin) that are ubiquitous in the millipede’s habitat or are produced by symbiotic microbes and may be readily available through food intake or aspiration.

Opisthonotal gland chemistry of a middle-derivative oribatid mite, Archegozetes longisetosus (Acari: Trhypochthoniidae)
TLDR
Gland reservoirs from molted exuviae contain a similar secretion, which proves the origin of the hexane extracts, and Active proto-, deuto- and tritonymphs have chemical profiles similar to that of adult mites, which distinguishes A. longisetosus from other studied species.
Volatile Exudates from the Oribatid Mite, Platynothrus peltifer
TLDR
The aromatic compound rhizoglyphinyl formate, also known from Astigmata, was found for the first time in extracts of Oribatida, whereas all other compounds have already been reported from other oribatid species.
Opisthonotal gland chemistry of early-derivative oribatid mites (Acari) and its relevance to systematic relationships of Astigmata
TLDR
Hexane extracts from four outgroup taxa without opisthonotal glands are characterized, providing evidence that Astigmata evolved from within the oribatid mites, at some level above the earliest Mixonomata; it is therefore consistent with the hypothesis that Astigmaata evolved within Desmonomata.

Chemistry of the oil gland secretion of Collohmannia gigantea (Acari: Oribatida)
TLDR
Findings from gas chromatographic profiles of whole body extracts of C. gigantea are consistent with the idea of astigmatid mite origin from a mixonomatan-desmonomatan group.
Scheloribatid Mites as the Source of Pumiliotoxins in Dendrobatid Frogs†
TLDR
One possible origin of pumiliotoxins, coccinellid alkaloids, and certain izidines found in poison frogs may be mites of the genus Scheloribates and perhaps related genera in the suborder Oribatida.
