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… 

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.

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.

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.

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.

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.

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.

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.

The mystery of the butterfly bush Buddleja davidii: How are the butterflies attracted?

It is found that olfactory cues are more attractive than visual cues, and that feeding behavior is only elicited by olfitory cues, most effectively by 4-oxoisophorone and oxoisophore epoxide, which was not known to elicit behavioral responses in pollinators before this study.



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.

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 extension

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.

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. spectral

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.

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.

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.


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.
