Abstract

S. pyrastri is obligate aphidophagous species. In all years of our investigations it was recorded as predator on M. persicae in tobacco fields. In laboratory conditions, larvae of this species consume 280- 563 aphids of M. persicae. Their voracity increases in the second, and especially in the third larval stage. Their larval stage lasts 7 - 12 days, or in average 8.79 days. It was stated that one generation develops in a period of 16 - 21 days, or 18 days in average. In tobacco region of Prilep, S. pyrastri was reported in tobacco field borders, neighbored by fruit gardens, in localities with garden crops, meadows and bushes. Beside Prilep, other tobacco regions in R. Macedonia where this species was reported are Bitola and Sveti Nikole.
