Larvae of the cabbage white Pieris rapae are specialists on plants belonging to the family Brassicaceae (Cruciferae). Adult females have been shown to use the glucosinolate gluconasturtiin (phenylethylglucosinolate) as a recognition cue for cruciferous plants, so they can identify an appropriate host for oviposition (Huang and Renwick in J Chem Ecol 20:1025–1037, 1994). Here, we report our results from a study of the role of this glucosinolate in feeding preferences of P. rapae larvae. The… 

Identification of a gustatory receptor tuned to sinigrin in the cabbage butterfly Pieris rapae

It is concluded that PrapGr28 is a gustatory receptor tuned to sinigrin in P. rapae, which paves the way for revealing the molecular basis of the relationships between crucifer plants and their specialist insects.

Olfactory response in caterpillars of Pieris rapae for host recognition

The plant-insect interaction was studied using three genotypes of the Brassicaceae family and the small cabbage butterfly and showed no significant preference for either genotype or treatment, except for the treatment of cauliflower where the larvae seem to prefer the odor of damaged plants over that of the control choice.

Experience-based behavioral and chemosensory changes in the generalist insect herbivore Helicoverpa armigera exposed to two deterrent plant chemicals

It is concluded that the experience-dependent behavioral plasticity of larvae of the polyphagous moth species Helicoverpa armigera was partly based on the reduced sensitivity of taste receptor neurons and that the desensitization of taste receptors contributed to the cross-habituation to the two chemicals.

Response to olfactory stimuli in gregarious Pieris brassicae caterpillars

It is clear that caterpillars of P. brassicae respond to olfactory signals, and the results showed no difference in preference for any of the undamaged genotypes, but a significant preference for damaged cauliflower over frass and the control (air).

Inheritance of electrophysiological responses to leaf saps of host- and nonhost plants in two Helicoverpa species and their hybrids.

Comparisons of taste neuron response patterns of parental species, F1 hybrids and backcrosses indicate that autosomal loci contributed to the difference in gustatory response patterns between the two Helicoverpa species with the H. armigera derived alleles being partly dominant to those carried by H. assulta.

Molecular identification and characterization of rhodaneses from the insect herbivore Pieris rapae

Two single-domain rhodaneses from P. rapae are identified and characterized, indicating an expansion of the rhodanese family in Pieridae and indicating different physiological roles.

Glucosinolates on the leaf surface perceived by insect herbivores: review of ambiguous results and new investigations

This work shows that a chloroform/methanol/water (2:1:1 vol/vol/vol) solvent leaf extract contains GS and, in addition, thia-triaza-fluorenes (TTF), other oviposition stimulants of the cabbage root fly, Delia radicum, and suggests that these compounds probably originated from deeper leaf layers and that herbivorous insects may penetrate the wax layer and perceive the stimulating compounds through the stomata.

Plant Metabolites Drive Different Responses in Caterpillars of Two Closely Related Helicoverpa Species

This is the first report showing that plant secondary metabolites could drive appetitive feedings in a generalist insect species, which gives new insights of underscoring the adaptation mechanism of herbivores to host plants.



Chemosensory tuning to a host recognition cue in the facultative specialist larvae of the moth Manduca sexta

Feeding on solanaceous foliage appears to result in a modification of the physiological responses of individual taste receptor cells that causes them to be tuned to the host-recognition cue indioside D, and it is proposed that this tuning is the basis for thehost-restricted larvae's strong behavioral preferences for solanoidal foliage.

Specialist deterrent chemoreceptors enable Pieris caterpillars to discriminate between chemically different deterrents

In behavioural preference experiments Pieris brassicae L. caterpillars preferred cardenolide‐treated cabbage leaf discs when confronted with a choice between them and a deterrent substance that does not occur in the Brassicaceae, demonstrating that the balance of activity elicited in the two types of deterrent chemoreceptors determines the behavioural decision.

Contact chemoreception of oviposition‐stimulating glucosinolates and an oviposition‐deterrent cardenolide in two subspecies of Pieris napi

Electrophysiological responses to ten glucosinolates, oviposition stimulants isolated from their cruciferous host plants, were recorded from tarsal taste neurones of two subspecies of Pieris napi, showing evolutionary divergence between the two geographically separated subspecies is reflected by differences in chemosensory recognition mechanisms.

Rejection of host plant by larvae of cabbage butterfly: Diet-dependent sensitivity to an antifeedant

It is demonstrated that dietary experience can dramatically affect the response of an insect to a potentially antifeedant compound in a plant, and larvae reared on a wheat germ diet were completely insensitive to the antifeeds.

Host recognition by the tobacco hornworm is mediated by a host plant compound

It is shown that the induced feeding preference of M. sexta involves the formation of a template to a steroidal glycoside, indioside D, that is present in solanaceous foliage that is both necessary and sufficient to maintain theinduced feeding preference.

Chemoreception of phenolic acids and flavonoids in larvae of two species of Pieris

Dose-response relations combined with phytochemical data permit the conclusion that naturally occurring levels of phenolic acids and flavonoids are stimulatory to some chemosensory neurones and can cause inhibition of activity in others.

Candidate codes in the gustatory system of caterpillars

Larvae of tobacco hornworms offer unique opportunities to relate the electrophysiological output of identified chemosensory neurons to specific behavioral responses, and events occurring in the tonic period, when all cells are firing, suggest a major role for this period.

The chemical world of crucivores: lures, treats and traps

Comparative studies indicate that common resistance mechanisms are involved and bioassays have been developed to elucidate the chemical nature of this resistance.

Experience‐based food consumption by larvae of Pieris rapae: addiction to glucosinolates?

Bioassays of cowpea extracts failed to show any deterrent activity and supported the conclusion that addiction to glucosinolates is responsible for the fixation of P. rapae larvae on their host plants.

Leaf surface compound fromBrassica oleracea (Cruciferae) induces oviposition byPieris brassicae (Lepidoptera: Pieridae)

It is argued that a high sensitivity for indole glucosinolates as host recognition factors may confer an adaptive value for these specialist crucifer feeders and the nutritional significance of their precursor tryptophan and the non-volatile nature of the aglycones formed upon enzymic hydrolysis in damaged tissues are proposed as properties of indoles glucos inolates that contribute to this possible adaptive advantage.
