摘要
为了有效防治橘小实蝇BactroceradorsalisHendel的危害,在红河州的青龙、南庄和临安石榴园作橘小实蝇田间种群动态定期调查,甲基丁香酚诱集,结果显示,橘小实蝇种群从11月起虫口密度锐减至最低水平,到7月开始回升,而后快速增长,2002年8月青龙最多达40.6头,高峰期延续到9月中旬的37.8头;2003年最高峰出现在9月上旬平均为28.7头然后开始下降。临安果园2003年在8月上旬出现高峰平均为29.8头,9月上旬再次出现高峰,平均为34头,然后下降;而南庄果园虫口数量波动不大。
From July to October 2002,and from July 2003 to march 2004,the population dynamic of the Bactrocera dorsalis Hendel was investigated every 7 days by fly-trapping with methyl eugenolin Jianshui megranate orcahard.The results showed as following:The density of the fly population dropped down the lowest level in November and recovered in July next year and then increased rapidly.In August 2002 the maximal quantity reached 40.6 in Qinglong and the high peak period lasted to mid-September (37.8).In the first ten days of September 2003 the high peak appeared with an average of 28.7 and them decreased gradually.In Linan orchard the high peak started in the first ten days of august and quantity was 29.8 in average.The second high peak was observed in the first ten days of September on the average of 34 and then descended afterward.But the fly population almost had no.
