We compared the chemical compositions of the osmeterial secretions of fourth and fifth (last) instars of eight swallowtail species of the tribe Papilionini. Four species (Papilio demoleus, P. polytes, P. paris, and P. macilentus) are Asian Rutaceae-feeding swallowtails. The other four (Chilasa epicydes, C. agestor, P. troilus, and P. glaucus) represent more distant clades within the Papilionini and species with larval hosts in other plant families. We conducted a quantitative analysis for six… Expand
The scent of alarm: ontogenetic and genetic variation in the osmeterial gland chemistry of Papilio glaucus (Papilionidae) caterpillars
TLDR
Terpene secretion was found to discourage attack by ants, whereas the switch from terpene to acid production rendered the caterpillars less palatable to a larger predator, the green anole. Expand
Antipredator activity and endogenous biosynthesis of defensive secretion in larval and pupal Delphastus catalinae (Horn) (Coleoptera: Coccinellidae)
TLDR
Experiments suggest that the wide use of alkaloids by more derived coccinellids may have arisen after their divergence from the more basal Microweisinae, a group for which chemical defenses have not been previously investigated. Expand
Are Aristolochic Acids Responsible for the Chemical Defence of Aposematic Larvae of Battus polydamas (L.) (Lepidoptera: Papilionidae)?
TLDR
The results suggest that the mixture of AAs I and AAs II have no defensive role against predators, at least against those investigated in the present work. Expand
Behavioral and antennal responses of Lobesia botrana (Lepidoptera: Tortricidae) to volatiles from the non-host plant Schinus molle L. (Anacardiaceae)
TLDR
It is found that non-host plant volatiles elicited electrophysiological and behavioral responses and that L. botrana can discriminate between doses. Expand
Antipredator activity and endogenous biosynthesis of defensive secretion in larval and pupal Delphastus catalinae (Horn) (Coleoptera: Coccinellidae)
TLDR
Experiments with D. catalinae larvae fed isotopically labeled glucose showed 13C-incorporation into both categories of compounds within the pupal secretion, demonstrating that these antipredator compounds, which differ from the typical nitrogenous defensive molecules of coccinellids, are biosynthesized endogenously.

The Prosternal Gland in Pacific Northwest Butterfly Larvae with Preliminary Chemical Analyses of Emissions
TLDR
The apparent widespread occurrence of prosternal glands in larvae of Nymphalidae and Hesperiidae suggests that this gland is important in the ecology of many species although experimental evidence for function is needed. Expand
Sequestration of aristolochic acids from meridic diets by larvae of Battus polydamas archidamas (Papilionidae: Troidini)
TLDR
The higher accumulation of AAs and the relatively higher proportion of AAI, one of the most toxic AAs, in the integument, suggest that their role is to deter attacks by natural enemies. Expand
The structure and defensive efficacy of glandular secretion of the larval osmeterium in Graphium agamemnon agamemnon Linnaeus, 1758 (Lepidoptera: Papilionidae)
TLDR
The defensive efficacy of the osmeterial secretion in larvae was examined, both in the laboratory and field, and was observed to be very complicated. Expand
Bornean caterpillar (Lepidoptera) constructs cocoon from Vatica rassak (Dipterocarpaceae) resin containing multiple deterrent compounds
TLDR
This is the first known case of a caterpillar building its cocoon entirely out of fragments of resin, broken away from sheets of dried resin on the trunk of a tree and held together with silk. Expand
Biosynthesis of volatile terpenes that accumulate in the secretory cavities of young leaves of Japanese pepper (Zanthoxylum piperitum): Isolation and functional characterization of monoterpene and sesquiterpene synthase genes.
TLDR
It is reported that monoterpenes and sesquiterpenes accumulate inside the secretory cavities of Japanese pepper leaves, but not in other parts of leaf tissues that do not include secretory Cavities. Expand

Constituents of osmeterial secretion of pre-final instar larvae of citrus swallowtail,Papilio demodocus (Esper) (Lepidoptera: Papilionidae)
TLDR
The defensive osmeterial secretion of pre-final instar larvae of the citrus swallowtail, Papilio demodocus was found to contain methyl 3-hydroxybutanoate, α-pinene, myrcene, limonene, β-phellandrene, (Z)-ocimene, (E-ocimenes, and germacrene-A, as well as a further number of unidentified sesquiterpenoid constituents.

Chemical nature of larval osmeterial secretions of papilionid butterflies in the generaParnassius, Sericinus andPachliopta
TLDR
In these three species, the chemical nature of the secretions of the last and the penultimate instars was essentially of similar quality, suggesting that the three genera, Parnassius, Sericinus, andPachliopta, are assigned to homogeneous types. Expand
Evidence for de Novo Biosynthesis of Osmeterial Secretions in Young Larvae of the Swallowtail Butterflies (Papilio): Deuterium Incorporation in Vivo into Sesquiterpene Hydrocarbons as Revealed by Mass Spectrometry
TLDR
Investigations on the origin of osmeterial secretions exuded by fourth instar larvae of Papilio helenus and P. protenor provide evidence for de nova biosynthesis of sesquiterpene hydrocarbons in young PapilIO larvae. Expand
Sequestration of aristolochic acids by the pipevine swallowtail, Battus philenor (L.): evidence and ecological implications
TLDR
This study confirmed that populations of B. philenor from Virginia and east Texas sequester aristolochic acids from its Aristolochia food plants, helping explain the abundant ecological data indicating that both immature and adult B. Philenor are unpalatable and protected from natural enemies. Expand
Volatile constituents of larval osmeterial secretions in Papilio protenor demetrius
TLDR
Remarkable differences were found between the chemical composition of the osmeterial secretions of 5th and the previous larval instars of a swallowtail, and chemical disparity appeared to be associated with the conspicous change of body colouration at the fourth larval ecdysis. Expand
Osmeterial secretions of papilionid larvae in the genera Luehdorfia, Graphium and Atrophaneura (lepidoptera)
TLDR
In all the species examined of the three genera, the secretions of the last and the penultimate larval instars were of similar composition, which is unlike the results reported previously for larvae of Papilio protenor. Expand
Larval osmeterial secretions of the swallowtails (Papilio)
  • K. Honda
  • Biology, Medicine
  • Journal of Chemical Ecology
  • 2004
TLDR
The chemical alteration of osmeterial exudate synchronized at the final larval ecdysis with the larval morphological change that appears to be of defensive significance against predators. Expand
Ecological adaptation of an Aristolochiaceae-feeding swallowtail butterfly,Atrophaneura alcinous, to aristolochic acids
TLDR
The cannibalistic activity of the larvae against the eggs and pupae seemed to be triggered by aristolochic acids present on the egg surface and pupal cuticle, suggesting a possible adaptive mechanism in this species. Expand
GC-MS and 13C-NMR studies on the biosynthesis of terpenoid defensive secretions by the larvae of papilionid butterflies (Luehdorfia and Papilio).
TLDR
The biosynthetic pathway of some terpenic hydrocarbons present in the larval osmeterial secretions of Luehdorfia and Papilio species was examined by in vivo experiments, using 13C-labelled acetic acid, substantiating de novo biosynthesis of terpenes from acetate precursors by these larvae. Expand
