This is a concern -- the small amount of fruit on these lateral canes is low on the plant and often hidden in foliage. This fruit should either be harvested or these canes should be removed with the fruit attached. Otherwise, SWD will multiply on the unharvested berries with high numbers of flies present and ready to attack the main primocane crop when it begins to ripen. Adult males are being found in traps, but in low numbers and in almost every case, larvae in fruit were noticed first. An article on management follows.
