I am looking for detailed information about how long the currant fruit fly is around after it has laid its eggs on the developing currant. I have had some success in keeping the fly from laying eggs on the berries by covering some of my bushes with bags made of floating row cover (remay cloth) which I didn't remover until I harvested the berries. Unfortunately, aphids abounded in the bags and of course the usual natural controls such as ladybeetles couldn't get in to do their work, nor could I wash the aphids off with the hose. So I would like to know when it would be safe to remove the bags (ie. when the currant fly adult has gone)and avoid the aphid problem. If anyone has detailed information about the lifecylce of the currant fruit fly pest, would you send it to me, or provide me with a link to it.
