From 1995 to 1998 the effects of aphids antagonists on aphids populations have been studied in some Emilia-Romagna peach orchards. The influence of different pest and disease control strategies on antagonist population was evaluated. The orchards with "advanced" IPM (control of Cydia molesta by mating disruption) where the best sites where antagonists are present and active. Coccinellids and Syrphids have been found in high numbers and alfa alfa fields nearby peach orchards also influenced the presence of antagonists. Population dynamic of the most important specie of Coleoptera Coccinellidae that has been found on peach: Adalia bipunctata L. was also investigated in 1997-98
