Abstract

The effectiveness of sterilization of males in pheromone traps in plum pest control has shown a reduction in fruit attack compared to untreated control. These indices essentially exceed the chemical standard that accounted for 69.3%. The biological effectiveness of the sterilization method was 89.8 - 91.8%. The researches proved that the oriental moth (Grapholita molesta Busck) in the Center area of the Republic of Moldova in 2016 the flight lasted from the II-nd decade of April to the III-rd decade of September in three generations. The use of Admiral 10EC for plum protection in the Republic of Moldova conditions contributed to preservation of natural entomofauna in the plum orchard and to the increase of the number of predators, thus favoring the quality and quantity of the harvest obtained.
