2021 - 52 weeks of doing something different

I wont be able to do something new every week but I will try companion planting this year. Last year I grew some aubergines. They were attacked first by aphids and when they died off, they were got by red spider mite. Can anyone suggest any companion plant(s) that might help in this situation? I think the mites started on a cucumber plant and then spread to the aubergines via some sweet peppers.
