| 摘 要： | 褐背小萤叶甲是烟田蓼科杂草的重要天敌,对蓼科杂草具有良好的自然控制作用.本文研究了该天敌的生物学特性,结果表明,褐背小萤叶甲有卵、幼虫、蛹、成虫4个虫态.室内强迫取食试验表明,褐背小萤叶甲属于寡食性昆虫,只取食蓼科的酸模属和蓼属植物,而对田间的其他农作物和经济作物安全.在三明地区,1年发生4代,在田间全年有两个高峰,分别在5月上旬和7月下旬,有世代重叠现象. |

| Abstract: | Galerucella grisescens is an important natural enemy which could significantly control Polygonaceae weeds in tobacco fields.The biological characteristics study showed G.grisescens was holometabolic insect.Compelled feeding to 56 farm crops and economic crops in 14 families showed that G.grisescens was an oligophagous insect,only feeding on Rumex and Polygonum weeds.It occurred four generations in the fields in Sanming,Fujian Province and had two peak annually.The peak appeared in the first ten days of May and the last ten days of July respectively.It had generations overlapping in the fields. |
| Keywords: | G.grisescens biological characteristics Polygonaceae weeds |
