This species has an important role in biological control of aphids in natural agroecosystems.
In all years of our investigations E. balteatus was recorded as predator on M. persicae in tobacco fields.
Beside Prilep, other tobacco regions in R. Macedonia where this species was reported are Bitola, Krusevo, Valandovo, Strumica, Stip and Sv. Nikole.
In laboratory conditions, larvae of this species consume 350-370 aphids of M. persicae. Their voracity increases in the second, and especially in the third larval stage.
Their larval stage lasts 7 - 11 days, or in average 9 days.
It was stated that one generation develops in a period of 15 - 20 days, or 18 days in average.
