“…Chemical communication plays an important role in their colonial life, particularly in the context of reproduction [5][6][7][8] . In the composition of cephalic secretions, involved in communication between drones, queens and workers, caste-, sex-and age-specific patterns were found in Scaptotrigona postica [9][10][11] . *e-mail: francke@chemie.uni-hamburg.…”

Os constituintes voláteis das secreções cefálicas de 11 espécies brasileiras de abelhas sem ferrão da linha Tetragonisca -Tetragona foram analisados. Foram identificados 145 compostos, por cromatografia gasosa e espectrometria de massas, dentre os quais 72 ésteres, 22 álcoois, 16 ácidos carboxílicos, 13 terpenos, 8 aldeídos, 4 compostos aromáticos, 2 lactonas e 1 diidropirano. As relações estruturais, origem e a distribuição detes compostos são discutidas. Com respeito à composição qualitativa e quantitativa, cada espécie mostra um buquê de odores, os quais são obtidos a partir de componentes poucos específicos. Em algumas espécies proximamente relacionadas foram observadas similaridades no buquê de odores. As fragmentações no espectro de massas de ésteres graxos e dos ésteres insaturados derivatizados com DMDS são discutidas em detalhes.The volatile constituents of cephalic secrections of 11 Brazilian social stingless bee species of the Tetragonisca -Tetragona line have been analysed. By gas chromatography/mass spectrometry 145 compounds could be identified which include 72 esters, 22 alcohols, 16 carboxylic acids, 13 terpenoids, 8 aldehydes, 7 ketones, 4 aromatic compounds, 2 lactones and 1 dihydropyran. Structural relations, origin, and distribution of these compounds are discussed. With respect to qualitative and quantitative composition, each species shows a specific odour pattern which is made up by less specific components. To a certain extent, closely related species show some similarities in the odour bouquets.The mass spectrometric fragmentation patterns of typical wax type esters and DMDS derivatives of unsaturated esters are discussed in detail.

“…The opisthonotal gland (or oil gland) secretions of four species of "glandulate Oribatida" (sensu Norton, 1998), belonging to the Arachnida, Nothrus palustris (Shimano et al 2002), Scheloribates azumaensis (Takada et al 2005), Hermannia convexa (Raspotnig et al 2005), and Oribotritia berlesei, have been shown to display typical nymph-adult polymorphisms (Raspotnig et al 2008). Ontogenetic chemical shifts also are known to occur in the alarm pheromone of the aphid Acyrthosiphon pisum (Mondor et al 2000), and in the composition of cephalic-gland volatiles of the stingless queen bee Scaptotrigora postica Latr (Hymenoptera, Apidae) (Engels et al 1993).…”

Chemical Polymorphism in Defense Secretions during Ontogenetic Development of the Millipede Niponia nodulosa

et al. 2014

A mixture of defense compounds (benzaldehyde, benzoyl cyanide, benzoic acid, mandelonitrile, and mandelonitrile benzoate), found commonly in cyanogenic polydesmid millipedes, was identified in the non-cyanogenic millipede Niponia nodulosa. These compounds were major components in 1st-4th instars, but were absent in older instars and adults. Extracts of older instars and adults contained 1-octen-3-ol, 2-methyl-2-bornene, E-2-octen-1-ol, 2-methyl-isoborneol, and geosmin; these compounds were minor components in 1st-4th instars. This ontogenetic allomone shift may be explained by the high cost of biosynthesis of polydesmid compounds from L-phenylalanine being offset by their potency in protecting the insect during fragile and sensitive growth stages. However, 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.

“…This unpredictable occurrence was not generally observed within the few stingless bees species that have been studied up to now. Hockings (1884) Engels and Engels (1988) and Engels et al (1993), virgin queens of S postica present different patterns of agedependent pheromone composition; this can be a rule for stingless bees. Imperatriz-Fonseca (1975) …”

“…Massive provisioning of the brood cells entails the need to keep gynes (virgin queens) in the colony to ensure its perenniality if the dominant queen dies. It is assumed that stingless bee queens have pheromonal control over worker activities and physiology, as occurs in other similar eusocial species (Engels et al, 1987(Engels et al, , 1993. Although the nature of such regulations is unknown, it probably differs from the closely related Apinae.…”
