Fruits of espalier apple are ripening now, and we are picking them soon.
I found wood debris on a branch of apple 'Alps Otome (=young girl)' yesterday.
It is a sign of pest; a larva of insect (Anoplophora malasiaca) is eating pith inside the branch. Those branches often die, and it can make a hole plant die.
So, it is a horrible pest for apple, and the pest attacks rose, too.

垣根づくりのリンゴが色づいてきて、もうすぐ収穫です.
リンゴの「アルプス乙女」の枝の上に木屑を昨日みつけました.
害虫のしるしで、ゴマダラカミキリの幼虫が枝の中で髄を食害しているのです.
枝が枯れることもあり、木全体を枯らすことさえあります.
そう、リンゴの大敵で、バラも被害を受けます.

I inserted a tip of a nozzle of pesticide splay into a small hole,
and sprayed it into a tunnel inside the branch.
殺虫剤のノズルの先端を小さな穴にいれて
枝の中のトンネルに噴霧しました.
