摘  要：
通过2011—2013年应用黏胶型性诱捕器和灯测2种方法对水稻二化螟越冬代成虫同地对比诱测试验,结果表明:性诱测第2蛾峰高峰日,与灯诱测的雌蛾始盛期相吻合,可以作为不同地理生态区和非灯诱监测区简化精准预测第1代二化螟发生期的重要依据,具有较强的实际指导价值。可以将该地此蛾峰日、峰日后的3~4 d、10~11 d分别作为预测雌蛾的发蛾始盛期、高峰期、盛末期,不同地区可根据实际确定和选取相应期距值。在此基础上,再加上相应的产卵前期和卵历期,就可对第1代二化螟卵孵始盛期、高峰期、盛末期作出预测。2011—2013年性诱预测结果与实际相符合。该法预测准确,简便易行,建议该技术在基层测报点推广应用。

摘  要：
The comparison experiment of the trapping effects between adhesivetype pheromone traps and light traps on the overwintering generation of Chilo suppressalis Walker was conducted from 2011 to 2013. The results showed that the second peak day of the moths detected by adhesivetype pheromone traps was consistent with the beginning period of female moths detected by the light traps, which was the important basis for predicting the mergence period of the 1 st generation of Chilo suppressalis Walker in different geographical and ecological zones or nonlight trap monitoring areas. The peak day, 3 or 4 days after the peak day, and 10 or 11 days after the peak day of the moths were regarded as the predictions of the beginning period, peak period and the ending period of the female moths, respectively. The periods could be selected via different facts in different zones. Then, plus the preoviposition time and the duration of egg, the hatching beginning period, peak period and ending period of the 1st generation of Chilo suppressalis Walker could be predicted. The prediction results from adhesivetype pheromone traps were consistent with the actual results obtained from 2011 to 2013. This method of prediction was accurate, simple and convenient, so the technology could be recommended and promoted.
