Editors: W. Müller, F. Polesny, C. Verheyden, A.D. Webster . aABSTRACT. Research at INIA Las Brujas has been focused to reduce insecticides input in fruit orchards. Mating disruption was the main tool developed to control oriental fruit moth (OFM), the major insect pest on peaches. No cover insecticide spray is necessary for early and midseason varieties, while for late varieties, two cover sprays are required to avoid OFM fruit damage. Mating disruption was also developed as a main tool, to reduce insecticide sprays on pears and apples, where codling moth (CM) is the major insect pest. Satisfactory results were achieved, however, elimination of insecticide sprays allowed leafrollers population to build up, with significant fruit damage. Leafrollers pheromone identification allowed the improvement of their chemical control. However some additional insecticide sprays were still necessary to avoid leafroller damage, with the consequent cost increase. For this reason, a new mating disruption strategy was evaluated. Half rate of Isomate-C dispensers (500/ha) plus some cover insecticide sprays to control leafrollers or abnormally high CM populations was tested. Results were very promising with substantial insecticide spray reductions comparing with commercial standard orchards, without increasing costs. @ International Society for Horticultural Science. aFRUITS aINSECT PESTS tActa Horticulturae, 1 March 2000, N° 525, p. 363-365.
