In this study we addressed a question of whether experimental manipulations that increase life span also reduce physical activity and molecular oxidative damage. We used three phenotypes of male and female Pyrrhocoris apterus that survive for differe

Great progress has recently been made in cryobiology. One field, however, has been neglected: the temporal sequence of the effects of photoperiod and temperature, and their relative importance in cold hardening. This is relevant to the question of im

Diapause fixation and development were studied in females of a Czech population of Aquarius paludum by monitoring changes in oxygen uptake, weight and reproduction potential in field adults between August and February. The fall in oxygen uptake relat

Three types of regulation of the corpus allatum (CA) activity were defined in females of the linden bug Pyrrhocoris apterus. First, short-term inhibition of the CA activity was found in starved or fed long-day females, or in short-day females. Inhibi

The quantification of phospholipid classes and the determination of their molecular structures are crucial in physiological and medical studies. This paper's target analytes are cell membrane phospholipids, which play an important role in the seasona

Juvenile hormone (JH) produced by the corpus allatum (CA) stimulates vitellogenesis and reduces the synthesis of hexamerin proteins in adult females of Pyrrhocoris apterus. At present it is unknown whether the signaling pathway involving the JH recep

Molecular studies on Drosophila melanogaster do not provide consistent results with regard to the hormonal regulation of a trade-off between life-span and fecundity. To unravel the physiological basis of the cost of reproduction without affecting ani

Adult females of Pyrrhocoris apterus, programmed for diapause by short-day (SD) photoperiod and those programmed for reproduction by long-day (LD) retain photoperiodic information in continuous darkness (DD) until death. However, if the interruption

Mechanisms of the suppression of gonadotropic activity of the corpus allatum (CA) in macropterous females were com- pared with those previously reported for either diapause or starving non-diapause brachypterous females by reciprocal transplanta- tio
