Never mind about aphids, pollen and flea beetles, they are natives and will be checked by natural processes to at least some extent. What about the invasive alien insects - only a problem for horticulture at the moment (fruit - spotted wing drosophila; onions/leeks - allium leaf miner and leek moth ) but farmings turn will come especially with climate change making conditions more suitable for Colorado beetle and western corn rootworm.
European corn borer would be a serious problem if it started hitting maize crops in the UK.
