- Abstract:
- Larval development of Raphidioptera takes one to three (sometimes even more) years with an obligatory cold stimulus to trigger regular ontogenesis. However, the quality of the stimulus has been unknown so far. Therefore mature larvae of Mongoloraphidia sororcula (ASPOCK & ASPOCK, 1966), Phaeostigma notata (FABRicius, 1781) and Raphidia mediterranea (ASPOCK, ASPOCK & RAUSCH, 1977) were experimentally hibernated for different periods of time at 4 C. Thereafter development was observed until onset of pupation. For all species the cold stimulus was sufficient for pupation, but rates of successful development were significantly different in the three species. Results are discussed with reference to the aspect of specific adaptation to environmental conditions and of synchronization of development.
