Humoral Immunity in Cecropia Pupae
1981There are four main reasons to study the factors which in nature regulate the equilibrium between insects and bacteria. Each of these reasons is of such a nature that it could be the subject for a review of its own. However, we will not elaborate but only state the arguments briefly as follows: 1. More than 106 insect species have been described

Molecules, 2014 The structural chemistry of proanthocyanidin molecules has been investigated in temperate zone plants, but few studies have been done with plants of the Amazonian lowland tropical wet forests where herbivore pressure is more extensive and diverse.

The optical activity of the Cecropia juvenile hormones
Biochemical and Biophysical Research Communications, 1970Abstract The juvenile hormones isolated from the Cecropia silk moth are not racemic. They exhibit a plain positive optical dispersion curve.

Ultrastructure of the myocardium of the moth, Hyalophora cecropia
Journal of Insect Physiology, 1968Abstract The tubular heart of the moth, Hyalophora cecropia , is composed of a single layer of striated muscle cells linked together by intercalated disks. The intercalated disk can be resolved into two components: interfibrillar junction and septate desmosome. The width of the cells varies from 10 to 30 μ and the cell length is 60 to 100 μ.

The hemocytes of Hyalophora cecropia (Lepidoptera)
Journal of Morphology, 1966AbstractThe hemocytes of selected stages of Hyalophora cecropia from first instar larvae to four‐day‐old adults were examined and compared with those of Samia cynthia and Antheraea polyphemus. Five classes and two subclasses of hemocytes are described in these moths: (1) prohemocytes, (2) plasmatocytes (of several morphological types), (3) spherule ...

A CYTOPLASMIC POLYHEDROSIS OF HYALOPHORA CECROPIA (LINNAEUS)
Canadian Journal of Microbiology, 1965Hyalophora cecropia (Linnaeus) is susceptible to infection by a cytoplasmic polyhedrosis virus. Electron microscope studies showed spherical viral particles known as "cores" which remain in groups of 12 to 17 subunits. The virus particles were embedded in a protein mass located in craters of the polyhedra.

Antibiotics in the Laboratory-Rearing of Cecropia Silkworms
Science, 1967A mixture of aureomycin and kanamycin prevents a fatal intestinal infection that usually occurs in all cecropia silkworms reared in the laboratory. Thus, for the first time, laboratory experimentation with these larvae and with those of other wild silkworms is practical.

Electrotonic junctions in cecropia moth ovaries
Developmental Biology, 1979Abstract The steady-state potential of the oocyte, resistance between the ooplasm and the medium, and electronic coupling between oocytes in adjacent follicles were examined in vitellogenic ovarioles of Hyalophora cecropia . The steady-state potential had a constant value of −40 mV throughout the 100-fold volume increase accompanying yolk deposition,
