Chemical and Chromatic Bases for Preferential Visiting By the Cabbage Butterfly, Pieris rapae, to Rape Flowers
TLDR
The present findings strongly suggest that this elaborate pollination strategy of rape flower, characterized by its good combination of olfactory and visual attractiveness, accounts for preferential visiting by the cabbage butterfly to the flower. Expand
Identification of Floral Volatiles From Ligustrum japonicum that Stimulate Flower-Visiting by Cabbage Butterfly, Pieris rapae
TLDR
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
Feeding responses of adult butterflies, Nymphalis xanthomelas, Kaniska canace and Vanessa indica, to components in tree sap and rotting fruits: synergistic effects of ethanol and acetic acid on sugar
TLDR
It is suggested that ethanol and acetic acid, together with sugars at low concentrations, synergistically stimulate butterfly feeding behaviour. Expand
Priority of color over scent during flower visitation by adult Vanessa indica butterflies
TLDR
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
Identification of feeding attractants in oak sap for adults of two nymphalid butterflies, Kaniska canace and Vanessa indica
TLDR
Results demonstrated that the sap odour stimulates foraging behaviour of the butterfly, and EAG responsiveness suggests that the olfactory receptors for these compounds might be few in the antenna and that the butterflies have enoughOlfactory sensitivity to the dose of 1 μg. Expand
Behavioral and electroantennographic responsiveness of adult butterflies of six nymphalid species to food-derived volatiles
TLDR
The results demonstrate that the olfactory preference for fermentation products is a characteristic of the rotting-food feeders and suggest that in food selection, adult butterflies use a specific Olfactory system to perceive these major food-derived volatiles. Expand
Species-specific chemical compositions of defense secretions from Parafontaria tonominea Attems and Riukiaria semicircularis semicircularis Takakuwa (Polydesmida: Xystodesmidae)
TLDR
A difference in the chemical composition of the defense secretion between the two species of millipedes is indicated, indicating that, for some reason, the two cyanogenetics are not secreted during methanolic extraction. Expand
Floral Scent of Osmanthus fragrans Discourages Foraging Behavior of Cabbage Butterfly, Pieris rapae
TLDR
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
1-Octen-3-ol Together with Geosmin: New Secretion Compounds from a Polydesmid Millipede, Niponia nodulosa
TLDR
Biological activity of 1-octen-3-ol suggests that this compound is involved in intraspecific communication in this millipede and may play a role as an alarm pheromone. Expand
From Terpenoids to Aliphatic Acids: Further Evidence for Late-Instar Switch in Osmeterial Defense as a Characteristic Trait of Swallowtail Butterflies in the Tribe Papilionini
TLDR
The heterogeneity of osmeterial chemistry in the tribe Papilionini may represent fine-tuning of chemical defense in response to shifting predation pressures as the larvae age and grow. Expand
