I believe plum, apricot, cherry, crab apple and even rose hips have been reported as hosts (not preferred) of apple maggot. Search "host of apple maggot" in Google.

If it were just plums, I'd think eastern cherry fruit fly, Rhagoletis cingulata, or maybe the black cherry fruit fly, Rhagoletis fausta. The coincidental occurrence with apple maggot makes it interesting. Maybe you're witnessing actual sympatric speciation in progress! Or maybe basing species differentiation on wing patterns and/or host selection is not particularly meaningful when it comes to Rhagoletis. In any event, from a management perspective, rather than an evolutionary ecology slant, I'd recommend Baythroid or Asana sprays on both plums and apples. Good luck.

In addition to apples, maggots (fly larvae) were also found in plums. This is the first time I have seen this. I am assuming they are apple maggot. Can anyone help with the following questions? 1) Do any other maggots infest plums? 2) There are peaches & nectarines adjacent to this area. I have not seen any literature suggesting that apple maggots get into peaches & nectarines, but want to be sure. Has anyone seen apple maggots in peaches or nectarines at a heavily infested site? We'll definitely hang AM traps in the plums next year!!
