Factors terminating ovarian arrest in long-winged females of a flightless bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

European Journal of Entomology, 2007
The aim of the present study was to determine the factors that are involved in termination of a non-diapause type of ovarian arrest in the adult macropterous females of a flightless bug, Pyrrhocoris apterus (L.), reared under a long-day (18L : 6D ...

Novel roles for the corpus allatum hormone in the cost of sexual interactions in the linden bug Pyrrhocoris apterus [PDF]

, 2015
The decrease of lifespan by mating is a common, yet poorly understood occurrence. Juvenile hormone (JH) is widely believed to mediate shortened lifespan in insect, caused by mating.

Schematic summary of dILP2-5 signaling effects on diapause. [PDF]

, 2016
(A) dILP2-5 signaling enhancement, obtained either through IPCs sensitization (NaChBac expression) or dilp2-5 over-expression (within IPCs or in other endocrine tissues, corpus allatum, corpus cardium and fat bodies) propels ovarian development even ...

The effect of ovary implants on juvenile hormone production by corpora allata of male Diploptera punctata

Journal of Insect Science, 2003
In the cockroach Diploptera punctata, vitellogenic basal oocytes stimulate juvenile hormone production by the corpora allata. Experiments with males were designed to determine whether oocytes must grow vitellogenically in order to stimulate juvenile ...

Do long- and short-winged adult females of the bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) differ in lifespan and reproductive capacity?

European Journal of Entomology, 2013
In the present study we tested whether long-winged (macropterous) and short-winged (brachypterous) adult females of the firebug Pyrrhocoris apterus (L.) differ in their reproductive capacity and length of life.

Methyl farnesoate plays a dual role in regulating Drosophila metamorphosis.

PLoS Genetics, 2015
Corpus allatum (CA) ablation results in juvenile hormone (JH) deficiency and pupal lethality in Drosophila. The fly CA produces and releases three sesquiterpenoid hormones: JH III bisepoxide (JHB3), JH III, and methyl farnesoate (MF).
