* 5. Anastatusa treba smatrati također jednim od prirodnih regulatora koji djeluju u ograničenom opsegu na smanjenje zaraze gubara, no s obzirom na spomenute činjenice u pogledu njegova kretanja i mogućnosti razmnažanja nema uslova, da se praktično primjeni u biološkom suzbijanju gubara.

Lypairis dispar. THE IMPORTANCE OF ANASTATUS DISPARIS RUSCKA THE PARASITE ON THE EGGS OF LYPARIS DISPAR IN´ THE NATURAL FIGHT AGAINST LIPARIS DISPAR In his brief discussion of the A, disparis of the author comes to the following con clusions : 1) A. disparis is spread in every plase where Liparis dispar is found. 2) A. disparis, although everywhere commmon, is not a decisive, factor in the fight against Liparis dispar, because it is spread mostly during the degradation of the appearance of Liparis dispar in mass. 3) A. disparis is strongly influenced by external factors and especially by clmatic circumstances. 4) The action of A, disparis is limited, for it attacks only fresh Liparis dispar eggs, the female does not fly, and deposes a too reduced number of eggs. 5) There are no conditions for a practical use of A. disparis in the biological fight against Liparis dispar. . 283 |
