Determining Relative Abundance and Distribution Patterns of Insect Pests
Abundance of pests on a crop is an important criterion for timing the screening of germplasms. Screening should be aimed against more than one key pest. This will facilitate developing resistant/tolerant variety against multiple species. Determining relative abundance also indicates the distribution patterns of the target insect species on the plant. Relative abundance also aids in developing sampling plans for the key pests.
