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.

Differences and similarities in cardenolide contents of queen and monarch butterflies in florida and their ecological and evolutionary implications

Journal of Chemical Ecology, 1985
Florida queen butterflies are highly variable in cardenolide content and, in three populations studied, contained less cardenolide than did a sample of sympatric Florida monarchs. The possibility that queens stored a more potent set of cardenolides from their host plants (and therefore were as well protected as monarchs, even at lower concentrations ...

The status of the African Queen butterfly, Danaus chrysippus (Linnaeus, 1758) (Lepidoptera: Nymphalidae, Danainae), in the Canary Islands, including an irruption on Fuerteventura

Entomologist's Gazette, 2021
Examination of museum collections and field work have established that Danaus chrysippus once inhabited five of the seven Canary Islands but is probably now confined to La Palma, La Gomera and Fuerteventura. It may be extinct on Gran Canaria and Tenerife.

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 ...

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 ...
