I opened the door every day and the aubergines were just inside it. Now that you mention it Colin I grew marigolds in my second tunnel and I didn't have aphid problems in there, but neither did I have aubergines. So I don't know if it would work on the aubergines.

Hi,
This year in my polytunnel, the only plants that got infected with aphids and whitefly were the aubergines. I grew two different varieties - black beauty and baby rosanna. Can anybody recommend resistant varieties for next year?
