| Abstract: |
1.在北京调查鳞喙白蛉占46.7%，中华白蛉占44.3%，许氏白蛉和蒙古白蛉较少。室内24小时观察白蛉在23时密度最高。观察到黑热病媒介中华白蛉的栖息性从家栖迁到野栖和半家栖，其白蛉季节为4个半月，高峰季节在六月中旬。北京平原地区白蛉基本消灭，而在山区、半山区白岭密度可高达230只/人工小时。
2.试验后证实了马拉硫磷及杀螟松灭白蛉效果好，持久效长，既经济又减少药物的用量。三年来在密云六个公社推广使用此两种药后，为国家节约了药费，降低了白蛉密度，并继续控制了黑热病新病人的发生。 |

1.There were 4 species of sandflies in suburbs of Beijing,namely Sergentomyia squamirostris, Phlebo omus chinensis, S. khawi and P.mongolensis. The former 2 accounted for 46.7% and 44.3% of the sandfly population respectively,and the latter2 were Less. The density of sandflies inside the room within 24 hours was observed and its maximum hotur was at 23:oo.We found that the habitat of the vevctor sandfly, P.chinensis,had changed from domestic to semi-domestic or wild places.The entire time of activity for P.chinensis was about 4½months, and its peak in mid-June. Sandflies entirely disap-peared in plain areas of Beijing,but they were still Present in mountainous and hilly areas in suburbs of sBeijing, in some places the density could reach 230 andflies caught/person/hour.
2.In our studies, we found that Malathion and Sumithion were more effective in the elimination of sandflies and their effects may be kept for a longer duration.They are cheaper and smaller in dosage.In a period of 3-year observation in 6 communes in su burbs of Beijing,the expenses for insecticides and the density of sandflies have been being greatly re duced due to the widespread use of these 2 insecticides in endemic areas, hence they benefit the control of kala azar. |
