蚌埠市白蚁危害及防治技术研究

Termite damage and its control technique in Bengbu city

通过对蚌埠市2007-2011年的白蚁出飞记录统计,发现蚌埠市白蚁出飞上报户数由2007年最多的91户降至2009年最少的49户,2010年反弹至79户。白蚁危害最为严重的多在木门框、木窗和门套处。2007年以来,蚌埠市主要使用毒死蜱、联苯菊酯、吡虫啉等药剂,通过加压注射的方法灭治白蚁;2009年开始使用粉剂氟虫腈用于喷粉灭杀白蚁;2010年氟铃脲(IPM饵站系统)灭治白蚁。在灭治白蚁之后,白蚁的返治率为氟铃脲(饵站系统)<氟虫腈<吡虫啉<毒死蜱<联苯菊酯,联苯菊酯灭治的效果较差。2008年返治率最高达到8.79%。通过近2年应用IPM饵站系统,发现此种方法高效、环保,返治率较低,并有利于整体控制蚁害,但投入人力物力相对较大。

In this study,the termite＇ s damage situation and control measure in Bengbu region are investigated. Through the statistics of termite＇ s mature groups fly outside from 2007 to 2010 in Bengbu city,91 houses in 2007,49 houses in 2009,79 houses in 2010. Termite often destroys wooden doorframes windows and door pocket in this region. Since 2007, chlorpyrifos, bifenthrin and imidacloprid were applied to control termite in Bengbu city by pressured injection method. Fipronil was used to control termite in 2009 and hexaflumuron （ IPM lure system） were adopted to control termite in 2010. Above control measures showed an obviously suppression to termite population. The Re-control ratio showed as following：hexaflumuron （ IPM lure system） 〈 fipronil 〈 imidacloprid 〈 chlorpyrifos 〈 bifenthrin. In 2008, the recontrol ratio was the highest 8.79% among these years. Bifenthrin was the worst to control termite. Especially,the above-ground station （IPM lure system） shows a good results to control termite in recently two years in Bengbu. The advantages above-ground station （IPM lure system） were highly effective, an environment-friendly, integrated control, whereas the disadvantage was consuming manpower and material resources.
