| 摘 要： | 调查了云南省文山县三七上的蓟马种群动态。结果表明:3~6月三七上蓟马发生数量较少,7月蓟马数量开始上升,8月中下旬蓟马逐渐增多,9~11月是发生高峰期,蓟马为害较重,11月下旬~翌年1~2月蓟马数量开始逐渐减少。3~4月,特别是3 a生三七,由于三七棵子被割,这一时期田间几乎无蓟马,从5~6月开始有少量的蓟马发生。因此,4月底或5月初是喷药防治蓟马的最佳时期。 |
| 关 键 词： | 三七 蓟马 种群动态 |

| Abstract: | The population dynamics of thrips on Panax notoginseng in Wenshan County,Yunnan Province was investigated.The results showed that there were few thrips in P.notoginseng from March to June,then the population increased on July,the peak appeared from September to November,the population decreased from the last ten-day period of November to the next February.Few thrips can be found from March to April,especially on 3 years old P.notoginseng because the stems were cut.A few of thrips occurred from May to June.So the insecticides should be spread from the end of April to the beginning of May. |
