The three modes of insect postembryonic development are ametaboly, hemimetaboly and
holometaboly, the latter being considered the only significant metamorphosis mode …

Juvenile hormone (JH) exerts major pleiotropic effects on cockroach development and
reproduction. The production of JH by the corpora allata (CA) in the adult female German …

Allatostatins with a typical YXFGL-amide C-terminus constitute a neuropeptide family, which
was discovered because of its inhibitory action on insect juvenile hormone synthesis. In the …

De novo synthesis of contact female sex pheromone and hydrocarbons in Blattella
germanica was examined using short in vivo incubations. Accumulation of pheromone on …

The roles of grouping and mating in modulating the activity of the corpora allata (CA) in adult
female cockroaches were investigated using the in vitro radiochemical assay of juvenile …

Patterns of juvenile hormone have been intensively studied in the cockroach Blattella
germanica under different physiological situations. However, data have been mainly …

Four allatostatic neuropeptides were isolated from extracts of the brain of the cockroach
Blattella germanica. The primary structures of these peptides were assigned as Leu-Tyr-Asp …

Allatostatins of the YXFGLamide group were discovered in cockroaches through their
capacity to inhibit juvenile hormone biosynthesis. Here, we assess the occurrence of …

The developmental fluctuations in immunoreactive ecdysteroids in the haemolymph of adult
female Blattella germanica (L.) are reported. There is a relatively low titre in freshly ecdysed …

With almost one million species described, and some nine millions still to be named, insects
are among the most successful creatures on earth. This formidable diversity is apparent not …
