They set the traps up so high I can't read the tags. Just glad they are monitoring whatever pest is prevalent. Consumers need to understand the truly in the trenches battles farmers go through. Medfly is short for Mediterranean Fruit Fly - a non native import that has been devastating. White fly sucks - literally. For localized infestations I lie down and water blast the underside of the leaves where the youngsters grow, cut off the plant parts that already are all black fungoide (bag and dispose NEVER compost) Then spray with insecticidal soap - repeat water blast and soap as needed. Of course an orchard can not do that so that mental barrier break of pesticide necessity...
As you travel across the country I am sure you encounter the agricultural checkpoints to try to halt import of crud. Arizona/California border especially - stop every car.
