THE IDENTIFICATION OF ENTOMOPHAGOUS COMPLEX IN THE APRICOT TREE ORCHARDS IN SOUTH-EASTERN ROMANIA

In order to prevent the negative effects of an exclusive chemical control of the phytopathogens and to decrease pesticide applications; biological and biotechnical methods were initiated.
The experiments were conducted at the Fruit Research Station Constanta.
Technical controls of the apricot harmful populations were conducted to maintain the damages under the economic threshold and to create a biocenotic balance in the ecosystem.
This paper deals with the observation in the apricot orchards (South-Eastern Romania) of the populations of some harmful species: Anarsia lineatella Zell., Cydia (Grapholitha) molesta Busck and Myzodes persicae Sulz. and their enemies.
There were identified 14 primary parasitoids which restrict A. lineatella Zell. population and G. molesta Busck and 4 secondary parasitoid species.
In the colonies of Myzodes persicae Sulz., 10 predatory species and 6 primary parasitoids were found wich may control this complex.
