Structure and properties of cocoons and silk fibers produced by Hyalophora cecropia
This paper shows that silk fibers produced by cecropia (Hyalophora cecropia) have similar tensile properties but different amino acid composition than that of mulberry (Bombyx mori) silk. The cecropia fibers are also much finer and have better strength and modulus than tasar silk, the most common non-mulberry silk. Cecropia is one of the largest silk producing moths and has similar lifecycle to...

متن کاملThe two juvenile hormones from the cecropia silk moth.
Some years ago we reviewed the status of the insect juvenile hormone (JH) and its isolation.1 Since then two noteworthy contributions toward purification of the hormone have appeared.2' In all these purification attempts adult male Cecropia silk moths4 proved to be an invaluable source material. The first nearly pure hormone preparation was isolated in 1965.1 We obtained it from Cecropia oil (s...
متن کاملDimorphic cocoons of the cecropia moth (Hyalophora cecropia): Morphological, behavioral, and biophysical differences
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 determine why cocoon dimorphism exists. We ...
متن کاملAdsorption of Methylene Blue from Aqueous Solutions by Silk Cocoon
This study concerns the performance of cocoons spun by silk worms as a natural adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption process, the effect of various parameters such as contact time, adsorbent dosage, dye initial concentration, and pH of the solution were investigated. According to the experiments, the kinetic data were best described by ...
