Sixth instars of the parsnip webworm, Depressaria pastinacella, orient by olfaction to bud, male flowers, and female flowers of their primary host plant, Pastinaca sativa. Because octyl acetate and octyl butyrate are characteristic of tissues consumed by the sixth instar, we investigated the influence of these esters on webworm feeding behavior and chemo-orientation. Although octyl acetate and octyl butyrate are feeding deterrents, and octyl butyrate is an olfactory repellent, octyl acetate… 

Behavioral Effect of Plant Volatiles Binding to Spodoptera littoralis Larval Odorant Receptors

TLDR
Nine odorant receptors tuned to plant volatiles as expressed in S. littoralis caterpillars are identified, allowing identification of some ORs whose activation is related to caterpillar attraction and may be promising targets for future plant protection strategies.

Aliphatic Esters as Targets of Esterase Activity in the Parsnip Webworm (Depressaria pastinacella)

TLDR
This study is the first to implicate esterases in lepidopteran larval midgut metabolism of aliphatic esters, ubiquitous constituents of flowers and fruits, and confirmed that webworms detoxify furanocoumarins and myristicin in their hostplants via cytochrome P450-mediated metabolism.

Volatile metabolites of willows determining host discrimination by adult Plagiodera versicolora

TLDR
Results of olfactometer bioassays show that the headspace volatiles from leaves of S. triandra significantly repelled adult beetles, suggesting that this species produces volatile repellents against P. versicolora, one of the most damaging insect pests to host and non-host willows.

Electrophysiological and behavioral responses of Spodoptera littoralis caterpillars to attractive and repellent plant volatiles

TLDR
This work characterized behavioral responses of Spodoptera littoralis larvae to 11 odorants found in plants using binary choices in a Petri dish assay, suggesting that olfactory neurons of caterpillars is broadly tuned to a range of odorants rather than being specialized to a few molecules.

Effects of florivory on floral volatile emissions and pollination success in the wild parsnip

TLDR
The effects of florivores on plant fitness are not limited to the removal of floral units but may also involve alterations in floral volatile composition, through damage-induced release and detoxification of particular constituents, that affect visitation and pollination success.

Tree-derived stimuli affecting host-selection response of larva and adult peach twig borers, Anarsia Lineatella (Zeller) (Lepidoptera: Gelechiidae)

TLDR
Volatiles from ripening peach fruit reportedly mediate host-finding by adult peach twig borers, Anarsia lineatella, but moths were repelled by in-situ ripe peach fruits, and by a blend of 22 synthetic volatiles associated with ripe peach fruit.

IMPLICATIONS OF ENEMY ESCAPE ON CHEMICALLY MEDIATED INTERACTIONS WITH MUTUALISTS : WILD PARSNIP POLLINATION IN TWO HEMISPHERES

TLDR
Examination of the influence of wild parsnip floral volatiles on pollinator attraction and seed production in NZ and the US finds that NZ flowers, in the absence of specialized florivores, may be chemically better constituted to attract pollinators.

Coupling transcriptomics and behaviour to unveil the olfactory system of Spodoptera exigua larvae

TLDR
This work sets the basis for the study of chemosensation in S. exigua larvae, boosting further studies aimed to characterize chemosensory-related genes that underlie ecologically-relevant behaviours of larval stage.

Coupling Transcriptomics and Behaviour to Unveil the Olfactory System of Spodoptera exigua Larvae.

TLDR
This work establishes the foundation for the study of chemosensation in S. exigua larvae, allowing further studies aimed to characterize chemosensory-related genes that underlie the ecologically relevant behaviours of larvae.

Chemical barriers to adaptation by a specialist herbivore

TLDR
The assumption that specialist herbivores such as the parsnip webworm are adapted to hostplant chemistry, and are therefore unaffected by chemical variation in hostplants, was tested.

Effects of Furanocoumarins on Feeding Behavior of Parsnip Webworms Depressaria pastinacella

TLDR
Octyl butyrate, a known deterrent to webworms, is highly correlated with furanocoumarin content, occurs in all plants, and differs significantly among normal and parthenocarpic fruit, suggesting that webworms may be able to avoid furanOCoumarins by virtue of their behavioral response to octylbutyrate.

Life History of the Parsnip Webworm, Depressaria pastinacella (Lepidoptera: Oecophoridae), in Central Iowa

Quantitative information on the life history of the parsnip webworm, Depressaria pastinacella (Duponchel), was gathered from three insect populations and their host plants in the Ames, Iowa, area.

Host Odor Perception in Phytophagous Insects

TLDR
In the present review selection was made mainly from the literature of the last 20 years.

GENETICS OF PHYSIOLOGICAL AND BEHAVIORAL RESISTANCE TO HOST FURANOCOUMARINS IN THE PARSNIP WEBWORM

TLDR
The presence of additive genetic variation in metabolism, and the absence of such variation in discriminative feeding behavior, suggests that adaptation to changes in furanocoumarin chemistry, resulting either from changes in the distribution of chemical phenotypes in parsnip populations or from shifts to new chemically different host plants, is likely to be facilitated by physiological rather than behavioral means.

CONSTRAINTS ON CHEMICAL COEVOLUTION: WILD PARSNIPS AND THE PARSNIP WEBWORM

TLDR
The wild parsnip and the Parsnip webworm appear to have reached an evolutionary “stalemate” in the coevolutionary arms race.

Acquisition of a native hostplant by an introduced oligophagous herbivore

An insect species that has been associated with a particular host may be expected to posess preadaptations that allow it to utilize related host species as it encounters them. If the related host has

Laboratory rearing of the parsnip webworm, Depressaria pastinacella (Lepidoptera: Oecophoridae)

TLDR
A procedure for establishing a laboratory colony of the parsnip webworm, Depressaria pastinacella (Duponchel), is described and an artificial oviposition substrate and a semidefined artificial diet for larvae were developed to allow year-round rearing with minimal reliance on fresh plant material.

TLDR
These findings indicate that, for the parsnip webworm, constructing a silken web reduces aggressive encounters among conspecifics.
