During the year 2013 under the bilateral project of the Institute of Genetics, Physiology and the Plant Protection Institute of ASM, together with scientists from Romania from Forest Research and Management Institute, Craiova Research Station and partners from University of Agricultural Sciences and Veterinary Medicine from Timisoara (Romania) were conducted a series of studies. There were monitored and mass captured Lepidoptera insect species (Tortrix viridana L., Helicoverpa armigera Hb., Grapholitha molesta Br., Grapholitha funebrana Tr., Laspeyresia pomonella L.,Cameraria ohridella Deschka & Dimic, Lymantria dispar L.) using pheromone traps in Botanical Garden and public parks of Republic Moldova and Romania. Monitoring and mass capturing of the males of main pest species using pheromone traps allow us to apply other biological methods of plant protection.. The biological efficacy of T. embryophagum Htg. and T. evanescens Westw, varied in different plant species (oak, mulberry, chestnut, plum, apple, flowers) from 64.5 to 73.3% in Moldova and from 36.3 to 75, 0 % of Romania.
