Comparative study on three calculation methods for mosquito dominance
Objective To explore a dominance calculation method from biomass,temporal,and spatial dimensions that can provide more real reflection of species dominance.Methods The mosquito surveillance data of Wuxi,Jiangsu Province,China from 2012 to 2021 were analyzed using Excel 2019 software.The Kendall's W coefficient was used to determine the consistency between the Time-Space index,Berger-Parker index,and McNaughton index.The results of the three calculation methods were compared using non-parametric Kruskal-Wallis H tests.Results The Kendall's W coefficients for the three dominance calculation methods of all species were all>0.900,with a significant difference between them of Culex tritaeniorhynchus,Aedes albopictus,Anopheles sinensis(all P<0.05).There were no significant differences in the three dominance indices for Cx.pipiens pallens/quinquefasciatus and Ar.subalbatus(χ2=1.157,P=0.561;χ2=4.622,P=0.099).For Cx.tritaeniorhynchus,Ae.albopictus,and An.sinensis,the Time-Space index was all significantly lower than the Berger-Parker index(Z=-2.192,P=0.028;Z=-2.343,P=0.019;Z=-2.041,P=0.041),and for An.sinensis,the McNaughton index was significantly lower than the Berger-Parker index(Z=-2.192,P=0.028).Conclusion The Time-Space index can significantly improve the resolution of distribution heterogeneity of certain species,which can better reflect the true state of relative dominance of species.
