ABSCISSION OF ANTHERS IN CECROPIA LOEFL [PDF]

open access: yesActa Botanica Neerlandica, 1977
Abscission of anthers was found in most Cecropia species studied for a taxonomic treatment of this genus for the Amazon region of Brazil*. Cecropia is a common genus in the neotropics. It comprises about 80 species. Most of them are arborescent pioneer plants and common in more or less open (secondary) vegetation.

Dimorphic cocoons of the cecropia moth (Hyalophora cecropia): Morphological, behavioral, and biophysical differences

open access: yesPLOS ONE, 2017
The larvae of the giant silk moth (Hyalophora cecropia) spin strikingly dimorphic, multilayered cocoons that are either large and fluffy (baggy) or significantly smaller and tightly woven (compact). Although these cocoon-morphs share the same function (i.e., housing for pupal to adult development during overwintering), previous work has been unable to ...

METAMORPHIC CHANGES OF PLATYSAMIA CECROPIA [PDF]

open access: yesThe Canadian Entomologist, 1877
In the early part of May, 1876, I secured a newly-developed female moth of the above species to a branch of the common red currant (Ribes rubrum). It was about seven o'clock in the evening of May 6th, to be more precise in regard to time. On the next morning, I visited the spot, and a lusty male was discovered in coition.

Absolute Configuration of Cecropia Juvenile Hormone [PDF]

open access: yesProceedings of the National Academy of Sciences, 1971
The absolute configuration of the predominant Cecropia hormone, methyl 12,14-dihomojuvenate, has been determined to be methyl ( E,E )-(10 R ,11 S )-(+)-10,11-epoxy-7-ethyl-3,11-dimethyl-2, 6-tridecadienoate (I). The less abundant hormone, methyl 12-homojuvenate, can be

Of Cecropias, Snarks and Boojums

open access: yesPlant Ecology & Diversity, 2011
We reply to Webber et al. (2011). Our study, Sheil and Padmanaba (2011), was a preliminary assessment of the alien Neotropical tree Cecropia around Bogor, West Java, Indonesia. We highlighted the need for low-cost assessment approaches for addressing alien species and considered what might be achieved by local actors with limited resources.

THE EFFECTS OF DIPHTHERIA TOXIN ON THE CECROPIA SILKWORM [PDF]

open access: yesJournal of General Physiology, 1952
1. The metamorphosis of the Cecropia silkworm is accompanied by large and systematic changes in the insect's sensitivity to diphtheria toxin. 2. Injection of less than 1 gamma of toxin into mature caterpillars, prepupae, or developing adults causes cessation of development followed by delayed death 1 to 5 weeks later.

GUSTATORY REJECTION THRESHOLDS FOR THE LARVAE OF THE CECROPIA MOTH, SAMIA CECROPIA (LINN.)

open access: yesThe Biological Bulletin, 1945
Rejection thresholds for HCl, CH3COOH, NaOH, NaCl, NH4Cl, KCl, CaCl2, and LiCl, presented as drops of solutions on leaves of the food plant, were determined for caterpillars of the cecropia moth, Samia cecropia. Rejection thresholds for glucose, sucrose, lactose, and strychnine sulfate either do not exist under these conditions, or are higher than the ...
