I suggest that any insect indicate that the plant is under stress, as they come in to clean up the lessor ones. Could it be that you have exhorted something from your soil or got it out of balance? Are there enough minerals available, it is easy to get too organic and not have the necessary minerals? Is there food for the soil biota? What is your BD program? (What are you actually applying?)
