| 摘 要： | 随着水稻病虫害绿色防控技术的不断发展,应用生态工程控制害虫技术已取得较大进展。本研究对实施生态工程控害技术稻田中的稻纵卷叶螟天敌功能团的种群数量及时空动态进行了连续5年的跟踪调查,分别于2009、2011和2013年用扫网法进行系统采样调查分析,以探明生态工程技术对稻纵卷叶螟天敌功能团的动态影响。结果表明,尽管年份之间以及不同水稻生育期的天敌功能团数量有差异,但实施生态工程防控技术稻田中的蜻蜓目天敌功能团、肖蛸科天敌功能团和幼虫寄生蜂天敌功能团的种群数量均显著高于农民自防田,分别提高了1.63~8.94、0~3.69和1.20~2.47倍,且数量逐年递增或维持较高水平。本研究结果说明通过实施水稻生态工程控害技术可以有效提高稻田稻纵卷叶螟天敌功能团的种群数量,这对减少化学农药使用和提高水稻生长中后期的天敌控害作用有重要的意义。

Natural Enemy Functional Guilds of Rice Leaf Folder (Cnaphalocrocis mendinalis) Enhanced in Paddy Field with Sustainable Pest Management by Ecological Engineering |

| Abstract: | With the increasing development of ecological control technologies of rice diseases and insect pests,a great progress has been made in sustainable management of rice insect pests by ecological engineering.This study investigated the spatiotemporal dynamics of natural enemy functional guilds of the rice leaf folder in successive 5 years in fields where ecological engineering technology was applied.The arthropod natural enemies were systematically sampled by sweep net in 2009,2011 and 2013,respectively.Natural enemies were identified to species where it was possible,and were classified into 9 natural enemy functional guilds (Odonata,Hemiptera,Coleoptera,Tetragnathidae,spiders,egg parasitoids,larva parasitoids,pupa parasitoids and Tachina fly).The results showed that the populations of functional guilds of predatory Odonata and Tetragnathidae as well as the larva parasitoids in the rice fields with ecological engineering technologies were significantly higher (1.63-8.94,0-3.69,1.20-2.47 times,respectively) than those in the farmer fields with traditional pest control technology,and the populations were increasing year by year or maintained at a high level.All the results reveal that the application of ecological engineering technology to control rice pests can effectively improve the population size of the functional guilds of the rice leaf folder's natural enemies,which is of great significance in reducing use of chemical pesticides and improve biological control by arthropod natural enemies in the middle and late stage of rice season. |
