Relationships between locomotor activity, oxidative damage and life span in males and females of the linden bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)
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 different lengths of time, diapausing insects, reproductive insects and insects from which the corpus allatum, the source of juvenile hormone, was surgica...
متن کاملEffect of thermoperiod on diapause intensity in Pyrrhocoris apterus (Heteroptera Pyrrhocoridae).
The intensity of adult diapause in Pyrrhocoris apterus was measured in two series of experiments as the duration of pre-oviposition period at a constant temperature of 25 degrees C after transfer from short (12L:12D) to long day conditions (18L:6D). Higher diapause intensity was induced with a thermoperiod than at constant temperatures. After the induction throughout larval instars 3-5 and duri...
متن کاملOverwintering strategy in Pyrrhocoris apterus (Heteroptera): the relations between life-cycle, chill tolerance and physiological adjustments.
Seasonal dynamics of ecophysiological parameters are described which are relevant to overwintering in field-collected adults of a Czech population of the red firebug, Pyrrhocoris apterus. Five life-cycle phases were distinguished using the duration of pre-oviposition period as a criterion: reproductive activity (spring-early summer), intensification of reproductive diapause (RD) (peak of summer...
متن کاملIndividual behaviour in firebugs (Pyrrhocoris apterus).
The concept of animal personalities has recently become of major interest as researchers began to wonder why animals within a given population show consistent behaviour across situations and contexts, what led to the evolution of such behavioural inflexibility and what mechanisms might underlie the phenomenon. A recent model explains individual differences in a population as the result of trade...
متن کاملDynamism in physiology and gene transcription during reproductive diapause in a heteropteran bug, Pyrrhocoris apterus.
Reproductive diapause was characterized in females of Pyrrhocoris apterus using physiological parameters (diapause intensity, photoperiodic responsiveness, oxygen consumption, mass and hydration) and changes in relative abundance of mRNA transcripts of eight different genes coding for proteins implemented in energy metabolism, cryoprotectant biosynthesis, biological clocks, and hormonal recepto...
