A new stereoselective synthesis of a terpenoid diol component of the pheromonal secretion of the queen butterfly.

Chemistry Letters, 1980
Abstract A terpenoid diol component of the pheromonal secretion of the queen butterfly was synthesized stereoselectively from geraniol by means of a site-specific terminal olefin functionalization and the subsequent anionic [2,3]-sigmatropic rearrangement of carbomethoxymethyl allylic sulfide.

Ophryocystis elektroscirrha sp. n., a Neogregarine Pathogen of the Monarch Butterfly Danaus plexippus (L.) and the Florida Queen Butterfly D. gilippus berenice Cramer1

The Journal of Protozoology, 1970
SYNOPSIS. Naturally occurring populations of the monarch butterfly, Danaus plexippus (L.) and the Florida queen butterfly D. gilippus berenice Cramer were found infected with Ophryocystis elektroscirrha sp. n. This neogregarine pathogen infects the hypodermal tissue, remains in micronclear schizogony until after pupation of the host, and then rapidly ...

Sex Pheromone of the Queen Butterfly: Electroantennogram Responses

Science, 1969
Olfactory receptor responses (electroantennograms) were recorded from antennae of danaid butterflies. Antennae of male and female queen butterflies ( Danaus gilippus berenice ) respond equally strongly to the hairpencil of queen males, to its crude extract, and to one of its two identified secretory components (the ...

Geographic and Temporal Variation of Cardenolide-Based Chemical Defenses of Queen Butterfly (Danaus gilippus) in Northern Florida

Journal of Chemical Ecology, 1998
The cardenolide-based chemical defenses of danaine butterflies vary macrogeographically. This study demonstrates that these defenses also vary both microgeographically and temporally. We sampled 280 queen butterflies (Danaus gilippus) at 11 sites in northern Florida during the summer of 1993 and determined their cardenolide concentrations and thin ...
