Cry, and wait for the inevitable 4 man gank with rift herald.
Seriously though, there's nothing you can do except be hyper safe and ask them to ward. Pinging in my experience does nothing because ADCs don't listen to pings.
You need to sit under tower and ask them, "hey can you ward that bush please?" Letting them die to it isn't a good idea, because hook champions like Thresh and Pyke are so overloaded that they will dive you next and the game will spiral out of control and consume the whole match before your jungler remembers there's a bot lane in this game.
It seems logical to ward, but in my experience a lot of ADCs probably couldn't walk and chew gum at the same time to save their lives, so remind them.
I haven't encountered many ADCs who don't ward since I've inched closer to Plat, but they still don't understand he importance of clearing control wards early. You can get ganked from tri bush 8 times in a row, and they still won't help you clear it.
