Abstract 

Calosoma sycophanta that fed with larvaes of L. dispar in area has harmonized biology of L. dispar in nature so Lymantria dispar (L.) (Sponge weaver) that damaged in forests of Quercus petraea can reduced to the natural balance limit. Morever, it feeds with caterpillars like Euproctis chrysorrhoea, Tortrix viridana that situated in area even if L.dispar occurs lately. Adults of Calosoma sycophanta are 30-40 mm length and live 3-4 years. When they feed very good, they spawn average 80 eggs in year. The eggs of them are 4-6 mm length, almost 1.5-2 mm width, elipsoidal shape and pale yellow. The eggs open in 4 days. Spawning period of a female can continue until 15 days according to the ambient conditions. The length of larvaes can extend until 4-4.5 mm. Adults of Calosoma sycophanta were brought to laboratory by collecting from area where Lymantria dispar damaged intensely. They placed in laboratory that had 20x20x40cm plastic pots mixing with %80 topsoil and %20 river sand, 22-230C, %60-65 moisture and 8:16 (day and night). The two each larvaes of Dendroctonus micans and the two each caterpillars of Lymantria dispar, Hyphantria cunea, Aglais urticae were given to adults every day. One female and two male were placed in producing pots with account from adults mating in the pots. The larvaes that hatching were fed with average 3.8 larvaes of D.micans and two each caterpillars. The larvaes of C. sycophanta that received trial ate average 49.4 larvaes of D.micans in the last three periods and average 8.4 caterpillars until mature larva stage. The larvaes of D.micans reduced maturation time of the larvaes of C. sycophanta, because they are rich with regard to protoin according to other foods. It was determined that adult of one C. sycophanta spawned average 49.7 eggs in laboratory.
