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.

The component of the sex pheromone of the German cockroach, 3, 11-dimethyl-2-nonacosanone (compound A), is a chiral compound. The chiral center at C-3 was assigned theS-configuration by ORD studies…

The phylogenetic tree inferred from the ITS2 region supported Zachvatkin’s morphological classification in the subfamily Rhizoglyphinae and is useful for the species identification of astigmatid mites and for studying low-level phylogenetic relationships.

Male leuconoe males seem to acquire the precursor for both of the PA fragments from the host plant,Parsonsia laevigata (Apocynaceae), during the larval stage; thereby they do not show pharmacophagous behavior towards PA-containing plants during the adult stage, however, males are pharmacophileously attracted to and feed on a number of simple phenolic compounds in a manner similar to other danaine species towards PAs.
Geraniol dehydrogenase, the key enzyme in biosynthesis of the alarm pheromone, from the astigmatid mite Carpoglyphus lactis (Acari: Carpoglyphidae)

- 1 June 2008
Geraniol dehydrogenase (GeDH), which plays an important role in the biosynthesis of neral, an alarm pheromone, was purified from the astigmatid mite Carpoglyphus’lactis and was shown to selectively oxidize geraniol, whereas its geometrical isomer, nerol, was inert as a substrate.
Behavioral Response of Males to Major Sex Pheromone Component, (Z,Z)-5,25-Hentriacontadiene, of Drosophila ananassae Females

- 1 August 1997
Cuticular hydrocarbon differences between D. ananassae and its close relative, D. pallidosa, and their roles in species recognition are discussed, and both hydrocarbons could elicit male courtship behavior.
