The use of pesticides on agricultural land has a negative impact on health, economic, and environment. The using of variety ofground cover plants as refugia area are expected to be an alternative habitat for pollinators insect in plants: Cyperus rotundus L., Bidenspilosa L., Commelina difussa L., Capsicum frutescens L., and Ageratum conyzoides L .. Observations made by visual control. Thisreseacch aims to know the composition of pollinators insect visit of ground cover plants and analyze their patterns. Analysis of the datastructure of insect communities in the spring and the fruit season obtained from INP and diversity (Shannon-Winner Index). Parametersare compared to diversity and abundance with ANOVA test, composition using Morisita Index. The results show that the abundanceof insect pollinators of spring higher at 7 families (31%) with H '= 1.698 instead of the fruit season is 6 families (25%) with H' =1.600. Abundance and diversity of pollinators insect in the spring and fruit season with a signifi cance of P < 0.05. Morisita similarityindex of 82%. Analysis of environmental factors of temperature, humidity, and light intensity on the abundance of insect pollinatorsfound positive correlation with R-square 87.5%.
