Abstract: To clarify the occurrence regularity of Grapholitha molesta adults and the control effect of sex pheromone traps, the occurrence regularity of G. molesta adults was systematically monitored with triangular sex pheromone traps and the control effect of two sex pheromone traps were studied. The results indicated that the peak occurrence time of G. molesta adults appeared three times. The first peak was from June 15 to July 1, the second peak was from July 23 to 29, and the third peak was from August 28 to September 3. The study on the control effect of the sex pheromone trap showed that both sex pheromone traps had control effects on G. molesta adults, and the triangular trap had better effect. The results clarifies the occurrence regularity and the control effect of sex pheromone traps for G. molesta adults in Yuncheng area, which could provide a scientific basis for the pest prediction and control.
