The biosynthesis of chrysomelidial and plagiodial was studied in the rove beetle subtribe Philonthina (Staphylinidae). [...] Key Result Glandular homogenates were found to convert synthetic (2E,6E)-[trideuteromethyl-5,5-(2)H(5)]octa-2,6-diene-1,8-diol (10) into nor-chrysomelidial (14) and nor-plagiodial (13). The overall transformation requires; i) oxidation of the substrate at C(1) and C(8), ii) cyclization of the resulting dialdehyde to nor-plagiodial followed by iii) isomerization to give nor-chrysomelidial…Expand
Chemical Composition of the Defensive Secretion of the Longhorned Beetle, Chloridolum loochooanum
TLDR
It is suggested that the absolute configuration of C. loochooanum iridodial is (1R,2S,5S), derived from (S)-citronellal, by enantioselective GC analysis.
Chrysomelidial in the Opisthonotal Glands of the Oribatid Mite, Oribotritia berlesei
TLDR
The chrysomelidials, as well as β-springene and octadecadienal, are newly identified compounds in the opisthonotal glands of oribatid mites and have chemotaxonomic potential for this group.
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.
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.
Pharmacophagy in green lacewings (Neuroptera: Chrysopidae: Chrysopa spp.)?
TLDR
Findings are consistent with the hypothesis that Chrysopa males feed on oviparae (the late-season pheromone producing stage of aphids) to obtain nepetalactol as a precursor to iridodial, and hypothesize that Asian Chrysopa eat A. polygama to obtain iridoid precursors in order to make their phersomone.
Characterization of an extracellular salicyl alcohol oxidase from larval defensive secretions of Chrysomela populi and Phratora vitellinae (Chrysomelina).
TLDR
The continuous formation of salicylaldehyde in the glandular reservoir can be compared to the operation of an enzyme reactor and hydrogen peroxide does not accumulate in native secretions but appears to be degraded most likely by a catalase.
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
De novo biosynthesis versus sequestration: a network of transport systems supports in iridoid producing leaf beetle larvae both modes of defense.
TLDR
It is demonstrated that the iridoid producing larvae of Plagiodera versicolora and Phratora laticollis have the potential to sequester precursors from food.
Independently recruited oxidases from the glucose-methanol-choline oxidoreductase family enabled chemical defences in leaf beetle larvae (subtribe Chrysomelina) to evolve
TLDR
The evolution of a host-independent chemical defence followed by a shift to ahost-dependent chemical defence in chrysomeline beetles coincided with the utilization of genes from different GMC subfamilies, illustrating the importance of the GMC multi-gene family for adaptive processes in plant–insect interactions.
Iridodials: enantiospecific synthesis and stereochemical assignment of the pheromone for the golden-eyed lacewing, Chrysopa oculata
1R,2S,5R,8R; 1R,2S,5R,8S; 1S,2S,5R,8R; and 1S,2S,5R,8S-Iridodials have been prepared in five steps from 4aS,7S,7aR and 4aS,7S,7aS-nepetalactones, major components of catnip oil. 1R,2S,5R,8R-Iridodial

TLDR
The morphologically unique defensive gland of the Xantholininae may be homologized with other abdominal glands of the Staphylinina and Philonthina, based on the common presence of iridoid defensive components.
