How to control and manage the pests of frankliniella occidentalis

Timing of Trapping

Trap selection

The blue sticky card is most sensitive trap to use for mass trapping frankliniella occidentalis.

Trap density 

For mass trapping about 15-45 traps would be for enclosed greenhouse areas.

For mass trapping about 225-300 traps per hectare would be for open fields.
