| 中文摘要: |
| 在不同生育期玉米田将中捷、纽康、百乐宝3种性诱芯分别置于中捷罐形、纽康锥桶形两种诱捕器中,分析对比其对草地贪夜蛾雄成虫的诱捕效果。结果表明,两种诱捕器对雄成虫的诱捕效果差异不显著;而中捷、纽康、百乐宝3种诱芯对草地贪夜蛾雄成虫诱捕效果存在显著差异,诱捕效果表现为:百乐宝>纽康>中捷。玉米生育期与草地贪夜蛾生存繁殖有着密切关系,虫口数量与玉米生育天数呈显著负相关,复种玉米苗期和拔节期是草地贪夜蛾幼虫活动取食最嗜好的时期。草地贪夜蛾的活动与傍晚田间气温存在显著相关性,周平均最低气温6.3~15℃时诱蛾量与周平均傍晚气温呈显著正相关。 |
| 英文摘要: |
| Three kinds of sexual lure cores, Zoje, Newkang and Bailebao, were placed into two kinds of traps, Zoje can trap and Newkang cone barrel trap in corn fields at different growth stages of corn to investigate their trapping effect to Spodoptera frugiperda. The trapping effect on male adults of S.frugiperda showed no significant difference between two types of traps, but trapping effect of the three kinds of sexual lure cores showed significant difference, of which Bailebao is the best one, and the Zoje showed the lowest trapping effect. The growth stage of corn has great influence on survival and reproduction of S.frugiperda. The number of trapped moth showed a significant negative correlation to the growth days of corn, at the seedling and jointing stage of multiple cropping maize is the best growing stage for the S.frugiperda larvae to eat and act. Our results also showed significant correlation between night activities of moths and field temperature in the evening. Weekly average evening temperature has positive correlation with the number of trapped male moths when weekly average lowest temperature between 6.3℃ and 15℃. |
