摘要
一、湿地松粉蚧发生为害概况目前在广东为害的粉蚧,标本经马里兰美国农业部研究中心的昆虫鉴定和益虫引进研究所Douglass R.Miller博士和杨平澜先生鉴定种名为Oracella acuta(Lobdell),英文名为loblolly pine mealybug,中文名直译应称为火炬松粉蚧,杨平澜和胡金林(1990)建议种的中名为“湿地松粉蚧”.可能是这种粉蚧在广东采集于湿地松,以为害湿地松为主,因而命名为“湿地松粉蚧”.因为“湿地松粉蚧”的中文名已传开了,为了说明方便,本文也采用“湿地松粉蚧”的名称.湿地松粉蚧主要分布在美国得克萨斯州到大西洋沿岸各州,如得克萨斯州,弗罗里达州,路易斯安那州,密西西比州,亚拉巴马州,佐治亚州,南卡罗纳州,北卡罗纳州,弗吉尼亚州,华盛顿州.主要寄主植物有火炬松Pinus taeda,矮松P.virginiana,萌芽松(又称短叶松)P.echinata,长叶松P.palustris,湿地松P.elliottii.以为害火炬松为主.
This paper reports the new invaded pest insect Oracella acuta infestation status in Guangdong Province. Comparison of host range, host distribution and climate condition in native distributed regions in Uuited States of America with parallel area in China have been made. A conclusion is that Oracella acuta will be able disperse to those loblolly pine growth areas between north of Guangdong Province and south of Yangzi River. To introduce natural enemies, such as Acerophagus coccois E. Smith, Chartocerus sp, and Allotropa sp. from pest's original habitats, as a cost-effectiveness way to control this pest insect is proposed.
