Concurrent with our expanding knowledge of the general field of endocrinology has come
the revelation that what was accepted as a central dogma is no longer true. In the case of …

Cutinase is an enzyme that catalyses the degradation of insoluble biopolyester cutin, a
structural component of plants. This enzyme has some properties of lipase and esterase …

Publisher Summary This chapter discusses the structure and function of major groups of
hemolymph proteins that are common to all insects, storage proteins, lipoproteins …

Mating elicits two well‐defined reactions in sexually matured females of many insects:
reduction of receptivity and increased oviposition. These post‐mating responses have been …

The in vitro production of juvenile hormone (JH) was investigated by using isolated ring
glands from third instar Drosophila melanogaster. A JH-like molecule is secreted that …

Juvenile hormones (JHs) are thought to drive the regulation of yolk protein uptake by ovaries
in Drosophila melanogaster. However, the level of JH production in a mutant stock (ap56f) is …

An enzyme immunoassay (EIA) reader capable of making kinetic determinations of change
in absorbance in the visible and near uv spectrum was evaluated for monitoring enzyme …

Females of Drosophila melanogaster held under short-day photoperiods at a moderately
low temperature (12°) enter a state of ovarian diapause in which yolk deposition in the …

Insect juvenile hormones are metabolized in numerous species of caterpillars by low
abundance, highly specific esterases. Because of their role in regulating and possibly …

Normal insect development requires a precisely timed, precipitous drop in hemolymph
juvenile hormone (JH) titer. This drop occurs through a coordinated halt in JH biosynthesis …
