| 摘 要： | 在中国科学院动物研究所提供的１１种烟草夜蛾ＨｅＬｉｏｔｈｉｓａｓｓｕｌｔａ性引诱剂合成样品中，以Ｂ，Ｄ，Ｅ３种诱蛾效果最优，Ａ，Ｃ，Ｆ次之，Ｇ，Ｈ，Ｉ，Ｊ，Ｋ较差；在同一时期内不同样品间或不同区组间的诱娥高峰日无显著差异；诱娥高峰日与累计蛾量达５０％的日期之间也无明显差异．本文还研究了诱蛾高峰日的蛾量与总诱蛾量的回归关系及诱蛾高峰日与下一代卵孵化高峰日的关系．

| Abstract: | Heliothis assulta Guenee is a important species of pest insect of tobacco andcapsicum in China. This paper reports the results of trapping and forecasting studies on thesynthetic female sex attracting substances of H. assulta synthesized by the Institute of Zoool-ogy,Academia Sinica. The results showed that among 11 formulas in trapping male moths ofH. assulta the three formulas B,D and E,are the best.A ,Cand F second best,and G,H,I,J,K the worst.During the same phase, the days on which most moths were attracted,have nodifference among different formulas or different blocks.And there is no difference betweenthe day when most moths are attracted and the day when accumulated moths reached 50%ofthe total moths in a generation of H. assulta. The regression equation between the moths ofhump day and the total moths,and the relation between the moth-hump-day and the egg-hatching-hump-day of next generation is also studied. |
