Abstract

Abstract:

【Objective】With the constant development of the sustainable rice pest management technologies, great progresses are expected to be made in the conservation of aquatic insects in paddy fields by controlling rice insect pests through ecological engineering technology. 【Method】We investigated the effects of the ecological engineering technology on the populations of aquatic insects in rice fields for continuous three years. 【Result】The results showed that the numbers of aquatic predatory damselflies, other predators and neutral insects in ecological engineering rice fields were significantly higher than those in farmer-managed fields, while the numbers of predatory damselflies and neutral insects near the ridges of rice field were significantly higher than those in the middle area of field. 【Conclusion】All results revealed that the ecological engineering technology could promote the breeding of aquatic predators and neutral insects in paddy fields, and could play a positive role in improving the natural control capacity during the later rice stage.

摘要：

目的随着水稻病虫害绿色防控技术的不断发展,希望应用生态工程控制害虫技术取得较大进展。方法对稻田水生昆虫成虫的种群动态进行了连续3年的系统调查,以探明生态工程防控技术对水生昆虫的影响。结果实施生态工程防控技术稻田中的水生捕食性昆虫豆娘的数量显著高于农民自防田,其他水生捕食性昆虫和中性昆虫等数量也有类似的结果,同时,靠近田埂的稻田区域豆娘和水生中性昆虫的种群数量也显著高于稻田中间区域。结论说明通过实施生态工程控害技术可以有效提高稻田水生捕食性昆虫及中性昆虫种群数量,这对提高水稻生长后期的天敌控害作用有重要的意义。
