The techniques I have heard of include:
1) Choosing resistant varieties. You could transplant onto your current tree with a number of varieties.
2) Planting vegetation that attracts predators of the problems.
3) Netting
4) running pigs and chickens through during the periods the problems are in their larval state.
5) Diverse plantings of different species and varieties
6) You could use “organic” interventions what ever the industry uses.
The above is what I have read but I have not yet had the opportunity to practice.
