摘要
研究结果表明,桃仁蜂成虫羽化期相对紧凑、集中,呈单高峰曲线。桃仁蜂成虫羽化出核具有明显的时段性,高峰时段为7:00—8:00,占总数的78 35%。羽化出核数量与气温关系密切,采用多种代换方式组建累积羽化率(%)(Y)与累积日均温(℃)(X)的单因子测报模型为Y=0 012466X+1 620477,测报准确率达到80 29%～93 84%。
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%.
