摘 要: | [目的]了解宜州市蔗区甘蔗螟虫的发生动态,为有效防治甘蔗螟虫提供参考。[方法]在宜州市洛东乡、河池市农业科学研究所选定有代表性的蔗地作为测报点,共设3个,每个测报点设3个诱捕点,每个诱捕点进行条螟、二点螟和黄螟的性诱测报,调查螟蛾诱捕量。[结果]宜州市蔗区条螟占总诱蛾量的71.6%,二点螟占24.5%,黄螟占3.9%,2010~2012年螟虫始见日分别出现在3月下旬、4月下旬和4月上旬,盛蛾期出现在4和6月,2次盛蛾期中二点螟较条螟分别早7和20 d,2012年诱蛾量较2010、2011年明显突出。[结论]宜州市蔗区主要受条螟为害,二点螟次之,黄螟零星发现,条螟、二点螟交叉为害,性诱剂对发生于前期的第1、2代螟蛾测报效果明显,防治应于4月中下旬、6月中下旬重点喷药,2012年宜州蔗区条螟、二点螟暴发性突出,螟害严重。

Abstract: | [ Objective] The trend of occurrence for sugarcane borer was assessed in order to provide reference for prevention and control of sugarcane borers effectively in Yizhou. [ Method] Three forecast points were located in sugarcane growing areas of Luodong Township, Hechi Research Institute of Agricultural Sciences in Yizhou City, at one which three traping points were located. [ Result ] The rate of Chilo sacchar- iphagus Bojer was 71.6% , Chilo infuscatellus Snellen was 24.5% , however Tetramoera schistaceana Snellen was least as 3.9% , in total. Sugarcane borer' s first appearance date was in the late ten days of March, the late and middle ten days of April respectively during 2010 - 2012, and the outbreak date of Chilo infuscatellus Snellen was one week earlier than Chilo sacchariphagus Bojer in the April and 20 days earlier in June. 2012 more prominent than 2010 and 2011. [ Conclusion ] Yizhou' s sugarcane area was mainly affected by Chilo sacchariphagus Bo- jet, followed by Chilo infuscatellus Snellen, and Tetramoera schistaceana Snellen was found in sporadic. They damaged with cross, and sex pheromone is suitable for the first, second generation mainly. Prevention and control should be arranged in the middle to late of April and the middle to late of June when pesticides would be respective sprayed two times continuously. In Yizhou, Chilo sacchariphagus Bojer and Chilo infuscatellus Snellen explosive appeared, sugarcane borer infestation was very common and serious in 2012. |
