Cardenolides fromErysimum cheiranthoides: Feeding deterrents toPieris rapae larvae.

Journal of chemical ecology

Sachdev-Gupta K, Radke C, Renwick JA, Dimock MB.
PMID: 24249167
J Chem Ecol. 1993 Jul;19(7):1355-69. doi: 10.1007/BF00984881.

Larvae of the cabbage butterfly,Pieris rapae, refuse to feed on the wild mustard,Erysimum cheiranthoides, due to the presence of alcoholextractable deterrents. The active components were extracted inton-BuOH, and this extract was separated into four fractions (I-IV) by reverse-phase HPLC....

High-resolution tandem mass spectrometry dataset reveals fragmentation patterns of cardiac glycosides in leaves of the foxglove plants.

Data Brief. 2020 Mar 20;30:105464. doi: 10.1016/j.dib.2020.105464. eCollection 2020 Jun.

Cardiac glycosides, steroid derivatives extracted from the foxglove plants, have been used for the treatment of heart failure since the 18th century. A method based on liquid chromatography coupled with high-resolution tandem mass spectrometry (LC/MS

Studies on the production of Digitalis cardenolides by plant tissue culture I. Determination of digitoxin and digoxin contents in first and second passage calli and organ redifferentiating calli of several Digitalis species by radioimmunoassay.

Plant & cell physiology

Hagimori M, Matsumoto T, Kisaki T.
PMID: 25385956
Plant Cell Physiol. 1980 Dec;21(8):1391-404. doi: 10.1093/pcp/21.8.1391.

With first and second passage calli induced from seedlings of Digitalis purpurea, D. lanata, D. lutea, D. mertonensis, D. ambigua and D. ferruginea Gigantea and those induced from leaf discs of D. purpurea and D. lanata, the contents of...

FORAGING DYNAMICS OF BIRD PREDATORS ON OVERWINTERING MONARCH BUTTERFLIES IN MEXICO.

Evolution; international journal of organic evolution

Brower LP, Calvert WH.
PMID: 28561370
Evolution. 1985 Jul;39(4):852-868. doi: 10.1111/j.1558-5646.1985.tb00427.x.

By suspending nets within and adjacent to a 2.25 hectare overwintering colony of monarch butterflies in Mexico, we estimated that black-backed orioles and black-headed grosbeaks killed 4,550 to 34,300 and an average of 15,067 butterflies per day. A conservative...

Dietary cardenolides enhance growth and change the direction of the fecundity-longevity trade-off in milkweed bugs (Heteroptera: Lygaeinae).

Sequestration, that is, the accumulation of plant toxins into body tissues for defense, was predicted to incur physiological costs and may require resistance traits different from those of non-sequestering insects. Alternatively, sequestering species could experience a cost in the...
