Species of Pseudoplatylabus in the Forest Zone of Eastern Europe

S p e c i e s c o m p o s i t i o n a n d a b u n d a n c e: Basedonresultsof20- years collectings by standard methods in the maximal possible number of different ecosystems of Forest Zone it is established that Pseudoplatylabus by an abundance in the nature takes 18 place from genera of Ichneumoninae Stenopneusticae (45 samples/ species in collections). The integrated indicator of abundance in the nature (quantity of the collected individuals / quantity of revealed species of a genus) among genera of Ichneumoninae Stenopneusticae constitutes 1,7%.

B i o t o p i c a l d i s t r i b u t i o n: Pseudoplatylabus violentus (GRAV.) prefers open ecosystems (68,8%), in a less degree – forests (31,2%). Among opened ecosystems in a maximal number ichneumon flies are presented on personal plots (31,2%), considerably lesser in the meadow ecosystems. Among forest ecosystems the greatest quantity of P. violentus was registered in more or less dry Pinetum pleuroziosum. In other types of pine forests, alder forests and oak forests it is found singularly. Pseudoplatylabus uniguttatus (GRAV.) was found singularly in pine forests (Pinetum pleuroziosum), alder forests (Alnetum urticosum) and personal plots. Representatives of the genus are fully absent in spruce forests.

S e a s o n a l a c t i v i t y a n d h i b e r n a t i o n: In conditions of Byelorussia, activity as females and males begins in the first half of May and finishing in October. Females and males appear simultaneously. Therefore, hibernation on imaginal stage is unlikely. Maximal activity of flying is fixed in July, second peak of activity, more weak, is observed in August.
