  • The emergence dynamics of Eurytoma maskovskii and the forecasting model were studied.The results showed that the emergence period of E.maslovskii was relatively compact and showed a mono-peak curve.The peak was in 7:00-9:30,accounting for 78.35% of the total emergence.The emergence was closely related to the weather.The mono-factor model of accumulative emergence rate and the accumulated average day temperature followed the equation of Y=0.009 694X+2.361 254.The precision rate was as high as 88.73%～98.90%.
