Females ofJunonia coenia (Nymphalidae), a specialist on plants that contain iridoid glycosides, were found to use aucubin and catalpol, iridoid glycosides typical of a host plant,Plantago lanceolata (Plantaginaceae), as oviposition cues. Incorporating dried ground leaf material or pure iridoid glycosides into agar disks proved to be a very effective method of testing. In no-choice tests and choice tests, females laid more eggs on disks withP. lanceolata leaf material or iridoid glycosides… Expand
Effect of Iridoid Glycoside Content on Oviposition Host Plant Choice and Parasitism in a Specialist Herbivore
TLDR
Parasitism by the specialist parasitoid wasp Cotesia melitaearum occurred most frequently in larval groups that were feeding on plants with low concentrations of catalpol, irrespective of year, population, and host plant species. Expand
Fate of iridoid glycosides in different life stages of the Buckeye,Junonia coenia (Lepidoptera: Nymphalidae)
TLDR
Feeding experiments suggested that this reduction in actively feeding larvae was due to the metabolism of iridoid glycosides, and calculation of irids consumption and utilization indices showed that larvae fed artificial diets consumed, digested, and sequestered aucubin and catalpol in similar ways. Expand
Fate of Host-Plant Iridoid Glycosides in Lepidopteran Larvae of Nymphalidae and Arcthdae
TLDR
The ability of larvae of six lepidopteran species to sequester iridoid glycosides was compared and it was found that, as expected, J. coenia larvae did contain iridoids, whereas V. cardui larvae did not. Expand
Lonicera Implexa Leaves Bearing Naturally Laid Eggs of the Specialist Herbivore Euphydryas Aurinia have Dramatically Greater Concentrations of Iridoid Glycosides than other Leaves
TLDR
The hypothesis that the specialist butterfly Euphydryas aurinia lays eggs on leaves of Lonicera implexa plants with greater iridoid concentrations is tested, which may provide specialist herbivores with compounds that they either sequester for their own defense or use as a means of avoiding competition for food from generalist herbivore.

Leaf variation in iridoid glycoside content ofPlantago lanceolata (Plantaginaceae) and oviposition of the buckeye,Junonia coenia (Nymphalidae)
SummaryChemical analysis of each individual leaf of fivePlantago lanceolata (Plantaginaceae) plants showed that iridoid glycoside content increased from undetectable in the oldest photosyntheticExpand

The ovipositional response of a Rutaceae-feeding papilionid butterfly,Papilio protenor, toCitrus host plants was evoked by the synergistic action ofl-(−)-stachydrine,d-(−)-quinic acid,Expand
Oviposition Cues for a Specialist Butterfly–Plant Chemistry and Size
TLDR
In the cages and in the field, the size of the plant appeared to be a more important stimulus than iridoid glycoside content, with bigger plants receiving more oviposition than smaller plants, regardless of their secondary chemistry. Expand
Ailanthus altissima Aqueous Extract Deters Spodoptera frugiperda Oviposition
TLDR
The observed change in behavior suggests that the deterrent properties of A. altissima phytochemicals may have economically important crop protection applications in controlling pest species like S. frugiperda. Expand
Synergistic Effects of Iridoid Glycosides on the Survival, Development and Immune Response of a Specialist Caterpillar, Junonia coenia (Nymphalidae)
TLDR
Multiple synergistic effects of iridoid glycosides are demonstrated and indicate a potential trade-off between larval performance and parasitoid resistance. Expand
Host-Plant Use in the Specialist Leaf Beetle Oreina gloriosa : the Role of Linear Furanocoumarins
TLDR
It is suggested that night activity of the larvae counteracts the toxicity of the photoactive furanocoumarins and should be considered a rare example of behavioural adaptation in a linear furanocentreins-specialized insect. Expand

TLDR
Iridoid glycosides were found to be sequestered by natural populations of Euphydryas anicia after ingestion from the host plants, and there appeared to be both sex and individual variation in host plant and/or iridoid glucoside utilization by E. anicia. Expand

TLDR
An investigation of Euphydryas phaeton (Drury) (Nymphalidae), the only eastern representative of the genus, revealed that when fed as larvae on the primary hostplant, Chelone glabra L. (Scrophulariaceae), the adult butterflies (as well as larvae and pupae) were unpalatable and emetic to birds. Expand

TLDR
Iridoid glycosides serve as feeding attractants and stimulants for larvae of Euphydryas chalcedona and are suggested as the basis of radiation in butterflies of the genusEuphydrya. Expand
