3. Rela onships between lea opper density and environmental factors 4. Rela onships between lea opper density and number of nest sizes and mango health Benefit 24
$ This study will provide information about the diversity of leafhoppers between Thailand and Cambodia, $ This study will result in the effects of leafhopper density on weaver ant population in mango orchard. $ This study can use the basic information for solving between leafhopper and weaver ant in mango orchard in the future.
