1978年我们发现广西有一种新的瘿螨为害甘蔗,经匡海源鉴定为甘蔗狭鼻瘿螨(Catarhinu sacchari kuang),为一新种。1979—1981年在南宁、铆州、玉林和钦州地区均发现这种瘿螨为害。局部地区虫口密度较大,为害较烈,如1979年7月在广西农学院农场一块宿根蔗调查,用20倍扩大镜观察,每个视野(0.78平方厘米)平均有5.5头,最多为26头:同年10月在武鸣华侨农场调查,平均每个视野有螨3头。被害叶呈现退绿色枯斑,重则焦枯。
In 1978, we found a new scab mite damage in Guangxi was identified as a new species of Catarhinu sacchari kuang by Kuang Haiyuan. 1979-1981 in Nanning, riveting state, Yulin and Qinzhou area found that scab mite damage. In some areas, pest population density was higher and the damage was more severe. For example, a piece of peanut cane was surveyed on the farm of Guangxi Agricultural College in July 1979 and observed with a magnifying glass of 20 times, with an average of 5.5 heads per field of view (0.78 cm 2) and a maximum of 26 heads : In the same year in Wuming overseas Chinese farms survey, on average, each field has 3 mites. Victim leaves showed green spots, while the focus is dry.
