The compound N -(17-hydroxylinolenoyl)-l-glutamine (named here volicitin) was isolated from oral secretions of beet armyworm caterpillars and induced the seedlings to emit volatile compounds that attract parasitic wasps and natural enemies of the herbivores.
The chemical defenses of a stylocellid (Arachnida, Opiliones, Stylocellidae) from Sulawesi with comparisons to other Cyphophthalmi
Two female specimens of an undescribed species of stylocellid harvestman from Sulawesi were extracted in methanol, and compounds in the product were identified by means of gas chromatography-mass spectrometry.

A previously unidentified class of compounds has been isolated from the regurgitant of the grasshopper species Schistocerca americana, providing further evidence of the ability of plants to detect and respond to a broad range of insect herbivore-produced compounds.
Historical Perspective and the Interpretation of Ecological Patterns: Defensive Compounds of Tiger Beetles (Coleoptera: Cicindelidae)

The results show that in systematic groups with four or more species analyzed, 34 of 39 pooled species were consistent within a group for the presence or absence of benzaldehyde, regardless of habitat type, which concludes that historical (phylogenetic) factors are likely to be generally important in interpreting ecological data, as either alternative or interactive processes.
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 secretion…
Pheromonal basis of aggregation in European earwig,Forficula auricularia L. (Dermaptera: Forficulidae)
It has been concluded from the bioassays of a number of authentic compounds and the lack of a chemically discernible difference between male and female extracts that the aggregation pheromone of F. auricularia is quite probably a minor component of the male cuticular lipids.
First Identification of a Putative Sex Pheromone in a Praying Mantid

Identification and synthesis of mantid pheromones may be a first step in attracting and aggregating these generalist predators for use in pest control.

Three quinones and two phenols were isolated from the defensive secretions of four species of opilionids (suborder Laniatores) from the Canal Zone.
The chemical defense of the Texas cave harvestman Chinquipellobunus madlae: first report on the family Stygnopsidae and on a North American troglobiont harvestman (Opilones: Gonyleptoidea)
The stygnopsid harvestman Chinquipellobunus madlae is known from numerous caves in eleven counties in Texas and is a highly adapted troglobiont, and the major volatile component of their chemical defense secretion was identified as 2-methyl-5-ethylphenol.
