致倦库蚊是传播班氏丝虫病的主要虫媒之一。由于蚊对化学药物的抗药性和化学杀虫剂引起环境的污染,生物防治法显现出巨大的发展潜势。本文报道在丝虫病高发地区巴西沿海城市奥林达检测生物防治效果的实验结果。在综合分析了该地区的地形气候特点、致倦库蚊的生活习性以及生物试剂性质等相关因素后,用Epi Info软件检测分析实验地区致倦库纹的密度以及居民丝虫感染率以检测球形芽胞杆菌控制和杀灭致倦库蚊幼虫的效果。
Culex pipiens quinquefasciatus is one of the major insect vectors that transmit Bancroftian filariasis. Because of the resistance of mosquitoes to chemical drugs and environmental pollution caused by chemical insecticides, the biological control method shows a great potential for development. This paper reports the results of experiments on the biological control of Olinda in the coastal coastal Brazilian cities with high prevalence of filariasis. After analyzing the topographic and climatic characteristics, the living habits of Culex pipiens pallens and the properties of biological agents in this area, the Epi Info software was used to detect and analyze the density and the infection rate of filamentous filariasis in the experimental areas to detect the spherical shape Bacillus control and kill Culex pipiens pallens larvae effect.
