目的 了解哀牢山微小按蚊数量变化与疟疾流行的关系。 方法 收集和分析哀牢山各年疟疾和按蚊监测报表资料和各种农作物种植以及当地气象资料情况并另进行相关性分析。 结果 疟疾发病率与微小按蚊数量变化有统计学意义(r=0.89,P<0.05),微小按蚊数量变化与分层在1100m海拔以上的村委会种植甘蔗有统计学意义(r=0.78,P<0.05)。 结论 半山区种植农作物变化对控制疟疾有重要作用。高疟区控制疟疾流行的关键是降低主要传疟媒介的密度,缩小分布范围。
Objective To understand the relationship between the change of the number of Anopheles minimus and malaria prevalence in Ailao Mountain. Methods The data of malaria and anopheles monitoring reports and the cultivation of various crops and the local meteorological data of Ailao Mountains were collected and analyzed, and the correlation analysis was carried out. Results The incidence of malaria and the quantity of Anopheles minimus had statistical significance (r = 0.89, P <0.05). The change of the population of Anopheles stephensi and sugarcane planting in the village committee stratified above 1100m above sea level were statistically significant (r = 0.78 , P <0.05). Conclusion Cropping changes in the mid-mountain area play an important role in controlling malaria. The key to controlling the malaria epidemic in high malaria areas is to reduce the density of the major malaria vectors and narrow the distribution.
