You'll probably have to deal with SOMETHING - but there are so many that trying to advise is difficult... just keep a sharp eye on your grow for any weird discolorations, bite marks, etc... You might want to have some BT on hand, maybe some Neem oil, maybe some Diatomaceous Earth, maybe some Spinosad... but it's expensive to go out and stock up... I'm assuming you can get your hands on remedies quickly so just keep your eyes out and ask questions if you see something amiss...
Good luck! I'm growing autos outdoors as well this year and a little bit nervous myself. I've just gotten some netting to fashion a hoop tent for them when they get in flower as I'm thinking that's going to be the critical time - that smell and the sweetness of the terps are going to be a siren call for bugs... you might think about doing something like that as well... just don't do it until you know approximately how HIGH your grow is going to be...
Cheers, mate!
