Spontaneous and evoked release of prothoracicotropin from multiple neurohemal organs of the tobacco hornworm

Carrow, Grant M., Calabrese, Ronald L., Williams, Carroll M.

Release of neurohormone from putative cephalic neurohemal organs was directly demonstrated in an insect. The prothoracicotropic hormone (PTTH) of the tobacco hornworm, Manduca sexta, was measured...

MITOCHONDRIA IN THE FLIGHT MUSCLES OF INSECTS : I. CHEMICAL COMPOSITION AND ENZYMATIC CONTENT

Watanabe, Mary Ishimoto, Williams, Carroll M.

1. The "indirect" thoracic muscles of adult dipterous and hymenopterous insects consist of a unique type of muscle characterized by the presence of numerous spherical, intracytoplasmic bodies termed...

THE EFFECTS OF DIPHTHERIA TOXIN ON THE CECROPIA SILKWORM

Pappenheimer, A. M., Williams, Carroll M.

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...

IMMUNOLOGICAL STUDIES OF INSECT METAMORPHOSIS : I. QUALITATIVE AND QUANTITATIVE DESCRIPTION OF THE BLOOD ANTIGENS OF THE CECROPIA SILKWORM

Telfer, William H., Williams, Carroll M.

1. The cell-free blood of the Cecropia silkworm produces a maximum of nine bands of antigen-antibody precipitate when reacted in antiserum-agar tests with antisera prepared by injecting Cecropia...

MITOCHONDRIA IN THE FLIGHT MUSCLES OF INSECTS : II. EFFECTS OF THE MEDIUM ON THE SIZE, FORM, AND ORGANIZATION OF ISOLATED SARCOSOMES

Watanabe, Mary Ishimoto, Williams, Carroll M.

1. The sarcosomes of Drosophila and the blowfly, Phormia, are dense, spherical, homogeneous bodies when isolated from flight muscle and promptly examined under the phase contrast, oil immersion...

MITOCHONDRIA IN THE FLIGHT MUSCLES OF INSECTS : III. MITOCHONDRIAL CYTOCHROME C IN RELATION TO THE AGING AND WING BEAT FREQUENCY OF FLIES

Levenbook, Leo, Williams, Carroll M.

1. In the present study a correlation has been sought between aging, flight muscle mitochrondria (sarcosomes), cytochrome c, and flight ability in the blowfly, Phormia regina. 2. During the 1st week...
