Liu P., Yang X., Wang Y.H., and Su X.Q., 2018, A preliminary study on the sustainability of mosquito-killing effect of Pythium guiyangense Su, Journal of Mosquito Research, 8(2): 14-17 (doi: 10.5376/jmr.2018.08.0002)

To study the sustainability of mosquito-killing effect of Pythium guiyangense Su, so as to develop new types of biological agents for mosquito control. Lab experiments and outdoor artificial simulate mosquito breeding water trials were carried out to observe how long the fungus can survive in water and maintain its capability to control mosquito larvae. Besides, a field experiment was made to test its mosquito control effect in real situation. The infection rate of the fungus increased along with the time of the experiments. In outdoor artificial mosquito breeding water, the observed fungal longest sustaining time was 273 days. In field trail, a 122-day of mosquito control was obtained. P. guiyangense can be used as a tool for long-term biological control of mosquitoes, and when combined with relative microbes we can develop new types of agents with high efficiency and sustainability.
