Researches concerning the pheromonal control of summer fruit tortrix moth (Adoxophyes orana, Hb) using the biotechnique "Attract and kill".

First results regarding the efficiency of the “Attract and kill” bio-technique was effectuated in 2008 at the Fruit Research-Development Station Bistrita. The product named “ AR Message” was elaborated by the researchers from the Institute of Chemistry Raluca Ripan, Cluj. The strategy of attraction and massive destroying through the bio-technique “Attract and kill” is based on the concept of combining two effects: the attraction through a synthetic pheromone of the adult male moths and the mass destroying of these with the aim of an insecticide . The observations effectuated in the research plot in 2008 shows that although the flying diagram of the adult male moths was on medium level the “Attract and kill” bio-technique gave good results in the control of the high damage creating first generation ( G1) and also at the second generation (G2). Additional results revealed a distinctive orientation for damaging of the summer tortrix moth male adults toward the two treatment cultivars from the experiment.
