Iowa State University has done some work showing that prairie strips improve biodiversity and boost pollinator populations. https://www.nrem.iastate.edu/research/STRIPS/FAQ2
These strips are wider than what you are planning and are perennial but it’s the same basic concept. Whether you could get enough of a boost from strips alone to eliminate the need for insecticides is an open question.
