The millipede Pachydesmus crassicutis (Wood) secretes a mixture of benzaldehyde and hydrogen cyanide when it is disturbed. These compounds are secreted through paired glands located on 11 of the notal projections of adult millipedes. Experiments with the imported fire ant demonstrate that these natural products serve a defensive function. 
Benzoyl cyanide in the defensive secretion of polydesmoid millipeds
A novel cyanogenetic compound, benzoyl cyanide, was isolated from the defensive secretion of 3 polydesmoid millipeds (Pseudopolydesmus serratus, Apheloria corrugata and A. trimaculata). The secretionExpand
Defensive secretion: biosynthesis of hydrogen cyanide and benzaldehyde from phenylalanine by a millipede
The polydesmid millipede, Oxidus gracilis, is able to convert dietary phenylalanine into benzaldehyde and hydrogen cyanide, components of its defensive secretion, and it is presumed that mandelonitrile is a precursor of HCN and benzaldehyde as has been demonstrated in plants. Expand
Benzaldehyde: defensive secretion of a harvester ant.
The xerophilous harvester ant Veromessor pergandei produces primarily benzaldehyde in its mandibular glands, which functions as an effective defensive secretion and a minor constituent, produced by the mandibia, functions as a releaser of alarm behavior. Expand
Mandelonitrile in larval secretion of mountain ash sawfly,Pristiphora geniculata (Hymenoptera: Tenthredinidae)
The larval defensive secretion of the mountain ash sawfly,Pristiphora geniculata, contains seven volatile components. They include benz-aldehyde, borneol, bornyl acetate, mandelonitrile, and C14,Expand
Benzoyl cyanide and mandelonitrile benzoate in the defensive secretions of millipedes
Analyses of the defensive secretions of 17 species of polydesmoid millipedes show that other chemicals besides HCN and benzaldehyde are liberated during cyanogenesis. Several members of the familiesExpand
The defensive secretion of the millipede, Nearctodesmus salix (Polydesmida: Nearctodesmidae)
No previous chemical studies have published on the defensive secretion of any member of the family Nearctodesmidae. Cyanogenesis has been documented in five families of the order Polydesmida:Expand
Intermediates in the biosynthesis of HCN and benzaldehyde by a polydesmid millipede, Harpaphe haydeniana (Wood).
Using 14 C and 3 H labelled compounds it was shown that this millipede synthesizes mandelonitrile by a mechanism similar to that in plants, and the pathway appears to be phenylalanineaN-hydroxyphenylalanineaphenylpyruvic acid oxime?aphetylacetaldoximeaphenyacetonitrile and/or 2 hydroxyphneylacetald Oximeamandelonitriles.

Cyanogenesis and the role of cyanogenic compounds in insects.
The cyanogenic system comprising cyanogenic glycosides, hydroxynitriles (cyanohydrins), beta-glucosidases and nitrile lyases is widespread in the plant kingdom but also occurs in several arthropods, and their function as defensive compounds seems likely on the basis of their ability to generate HCN and their localization.

In sorghum the several biosynthetic enzymes catalyzing the flow of carbon atoms from l-tyrosine through such nitrogenous intermediates are located in a membrane fraction and may be capable of metabolic channeling. Expand
A nitriloside is a naturally occurring or synthetic compound which upon hydrolysis by a beta-glucosidase yields a molecule of a non-sugar, or aglycone, a molecule of free hydrogen cyanide, and one orExpand

The occurrence of para-quinones in some arthropods, with emphasis on the quinone-secreting tracheal glands of Diploptera punctata (Blattaria)
The morphology, histology, and histochemistry of the quinone-secreting glands are described and the secretion from the abdominal and thoracic odoriferous glands of the tenebrionid beetle Diaperis maculata was identified as a mixture of 2-ethyl-1,4-benzoquinone and 2-methyl,1, 4-benzosquinone.
