Successful spraying against Cjdiia pomonelki (L.), the main pome fruits pest in Iraq orchards, depends on correct timing, which was determined by the degree-days model or at intervals of 100 k 10 degree-days after the biofix.Sprays are most effective against the newly hatched larvae before entry into the fruits. The optimum timing with laresban treatments was determined to be at 200 degree-days after the biofix or after an average degree-days accumulation of 195 DD (SD = 59) and 298 DD (SD = 67) when daily degree-days calculated by the method of the sine-wave. ~~ ; , 1973: Codling moth: Use of codlemonebaited traps
