Chemical and Chromatic Bases for Preferential Visiting By the Cabbage Butterfly, Pieris rapae, to Rape Flowers

Scent and coloration of corolla were examined as floral attributes responsible for preferential visiting by the cabbage butterfly, Pieris rapae, to rape flower, Brassica rapa. Floral volatile components that release the flower-visiting behavior of the butterfly were identified by chemical analyses, electroantennography (EAG), and two behavioral bioassays: proboscis extension reflex (PER) in response to odor and attraction to artificial flowers. GC and GC-MS analyses of the headspace volatiles… Expand

Floral Scent of Osmanthus fragrans Discourages Foraging Behavior of Cabbage Butterfly, Pieris rapae
The present results clearly indicate that the repellency of a compound is correlated with its deterrent effect on PER but not necessarily with antennal sensitivity. Expand
Nursery pollination by a moth in Silene latifolia: the role of odours in eliciting antennal and behavioural responses.
The results show that the most common and abundant floral scent compounds in S. latifolia, lilac aldehydes, attracted most of the moths tested, indicating a specific adaptation of H. bicruris to its host plant. Expand
Priority of color over scent during flower visitation by adult Vanessa indica butterflies
The results demonstrate that V. indica depends primarily on color and secondarily on scent during flower visitation, and the preference hierarchy between these cues is revealed using the naïve adult butterfly Vanessa indica. Expand
Antennal responses to floral scents in the butterflies Inachis io, Aglais urticae (Nymphalidae), and Gonepteryx rhamni (Pieridae)
The butterflies showed antennal responses to most of the floral scent compounds from both natural and synthetic blends except to the highly volatile monoterpene alkenes, which points to their biological importance. Expand
Antennal Responses to Floral Scents in the Butterfly Heliconius melpomene
The findings suggest that several floral scent volatiles, especially those of exclusively floral origin, are of high biological significance to H. melpomene butterflies. Expand
Flower color-flower scent associations in polymorphic Hesperis matronalis (Brassicaceae).
Floral scent emission rate and composition of purple and white flower color morphs of Hesperis matronalis (Brassicaceae) were determined for two populations and, for each, at two times of day usingExpand
Phenylacetaldehyde attracts male and female apple clearwing moths, Synanthedon myopaeformis, to inflorescences of showy milkweed, Asclepias speciosa
Investigation of the relative importance of visual and olfactory cues, and the key floral semiochemical(s) mediating attraction of S. myopaeformis to the inflorescences of A. speciosa finds phenylacetaldehyde induced the most frequent proboscis extension reflexes of male and female moths. Expand
Variation in floral scent compounds recognized by honeybees in Brassicaceae crop species
It is suggested that all species require pollinator visits for reproduction, despite their different reproductive systems, and the inter-genus and intra-specific variations shown by the multiple groups within a species might cause different visitation frequencies by pollinators between genera and among accessions within aspecies, resulting in insufficient seed production in some accessions or species.

Effects of mating on host selection by female small white butterflies Pieris rapae (Lepidoptera: Pieridae)
Investigation of the post-mating changes in behavioral and antennal responses of Pieris rapae (Lepidoptera: Pieridae) females to host plant volatiles found mating enhanced the host-finding behavior of young females and their responsiveness to plantvolatiles. Expand
Wavelength-Specific Behavior of the Western Flower Thrips (Frankliniella occidentalis): Evidence for a Blue-Green Chromatic Mechanism
The western flower thrips (Frankliniella occidentalis) exhibits two different wavelength specific behaviors towards blue and green, and compelling indications are provided that these behaviors are controlled by two photoreceptors maximally sensitive in theblue and green range with an inhibitory chromatic interaction between both.

Identification of Floral Volatiles From Ligustrum japonicum that Stimulate Flower-Visiting by Cabbage Butterfly, Pieris rapae
The present results strongly suggest that specific floral volatiles may facilitate close-range flower location by P. rapae and that a synergistic effect of the five floral components would be most responsible for attraction of the butterfly to this flower. Expand
Identification of Floral Volatiles Involved in Recognition of Oilseed Rape Flowers, Brassica napus by Honeybees, Apis mellifera
Volatiles from oilseed rape, Brassica napus, flowers were sampled by air entrainment and their relevance to the natural odor profile of the flowers was confirmed by conditioned proboscis extensionExpand
The learning abilities of the white cabbage butterfly,Pieris rapae, foraging for flowers
This study examines the role of learning and memory in the butterfly Pieris rapae crucivora Boisduval during foraging for flowers, and indicates that it keeps memory for a period longer than 3 days, and that it can remember at least two flower species as suitable flower resources. Expand

Abstract A checklist is presented of floral scent compounds retrieved by head-space techniques and separated and identified mainly by gas chromatography and mass spectrometry. The checklist is basedExpand
Spectral polymorphisms in angiosperm flowers determined by differential ultraviolet reflectance
The ultraviolet reflectance pattern of flowers from 54 species representing 22 families, many native or introduced to Japan, were surveyed. Their differential ultraviolet patterns, i.e. spectralExpand
Preferential pollination of yellow-flowered morphs of Raphanus raphanistrum by Pieris and Eristalis spp.
I have observed extremely strong discrimination by some insect pollinators between the yellow and white corolla-colour forms of polymorphic wild radish, indicating that coroll-colour differences are of adaptive importance in this and similar cases. Expand
Foraging strategies in the small skipper butterfly, Thymelicus flavus : when to switch?
Investigating foraging patterns under natural conditions casts doubt on explanations for flower constancy as an adaptive strategy that minimizes handling time and maximizes resource acquisition per unit time within learning constraints. Expand
Associative colour learning in a nymphalid butterfly
To examine the importance of innate preferences and learned associations in flower colour choice in Agraulis vanillae L.vanillae, naive and experienced individuals were offered non-rewarding and rewarding flowers of the same morphology in two different colours. Expand
Headspace volatiles of whole plants and macerated plant parts of Brassica and Sinapis
Headspace volatiles collected from six Crucifer species of the two genera Brassica and Sinapis were investigated by GC/MS and a total of 34 compounds were identified from both whole plants and macerated plant parts, several of which have, to the authors' knowledge, not been previously reported.

Ultraviolet floral patterns which act as nectar guides to pollinators are described and in some cases patterns differ between closely related taxa and could therefore be of diagnostic value. Expand
