Pear midge can ruin a crop. You’ll know there is a problem if the following occurs:
-Infested pear fruitlets initially grow faster and are softer than healthy fruitlets but during May they begin to turn black at the eye end of the fruit (opposite end to the stalk);
-The black colour spreads up the fruitlet and it drops off in June;
-A high proportion of the potential crop can be lost in this way;
-Inside the damaged fruitlets are many orange white maggots, up to 4mm in length.
