A 2‐year study was performed on the effect of Cydia molesta on the incidence of Monilinia spp. on quince fuits. In Yugoslavia C. molesta regularly occurs in the Čačak area (western Serbia) and is a highly important pest of peach and quince. In Yugoslav conditions it develops four generations a year. The 1st and 2nd generations usually develop on peach and the 3rd and 4th on quince. The proportion of quince fruits injured by C. molesta can reach 78%, with up to 12 caterpillars per fruit. C. molesta had a great effect on the incidence of Monilinia spp. on quince fruits. Of the total number of fruits affected by fruit rot, 84 and 88% had been injured by C. molesta in 1987 and 1988, respectively. Timely control of C. molesta is the most effective measure against the incidence of Monilinia spp. on quince fruits.
