目的观察飞机防治胡杨林春尺蠖对荒漠型黑热病的控制效果。方法以荒漠型黑热病疫区巴楚县夏河林场和伽师县三乡作为研究现场,其中前者为实验区,后者作为对照区。实验区处理:2009年4月底用AT-402B型飞机,对3 200 hm~2胡杨林区害虫春尺蠖喷洒灭虫药;对照区处理:2008-2009年和2014-2016年荒漠型黑热病流行期,对黑热病患者住宅及其周边10户范围以内的宅院室内喷洒菊酯类卫生杀虫剂用于杀灭白蛉,2015年在此基础上增加了婴幼儿蚊帐防蛉措施。结果实验区2009年飞机灭虫前,黑热病发病率维持在160/10万~260/10万,灭虫后连续7年在60/10万以下;对照区2010年后黑热病发病率下降到60/10万以下,但2014-2016年(6月)又分别回升至201/10万、602/10万和325/10万。结论在荒漠型黑热病流行期,飞机灭虫比院落灭虫对疫情控制效果显著,且持续时间长。
Objective To observe the control effect of Plane against Desert Kalahala Disease by Populus euphratica. Methods The study area was located in Xiahe Forest Farm of Bachu County and Sanxiang Township of Jiashi County in desertification-type kala-azithriasis-endemic areas, the former being the experimental area and the latter being the control area. Experimental Area Treatment: At the end of April 2009, AT-402B aircraft was used to spray insecticide on the pest spring vermilion in 3 200 hm ~ 2 Populus euphratica forest area. Control area treatment: During the epidemic period of ZST in 2008-2009 and 2014-2016, In addition, pyrethroid sanitation insecticides were sprayed on indoor premises of houses and the surrounding area of 10 people in the area of kala-azar for the purpose of killing the heliotrope. In 2015, the preventive measures against mosquito nets for infants and young children were added. Results In 2009, the incidence of kala-azar was maintained at 160 / 100,000-260 / 100,000 before the pest-killing of the aircraft in the experimental area and 60 / 100,000 for 7 consecutive years after pest control. In the control area, the incidence of kala-azar fell to 60 / However, it rose to 201/10, 602/10, and 325/10 respectively in 2014-2016 (June). Conclusion During the epidemic period of desert kala-azar, the control effect of plane pest control over pest control in the hospital was significant and lasts long.
