Keep an eye out for apple maggot fly

I’ve seen noticeably fewer insects in my garden this year. It’s probably due to the relatively cool temperatures we’ve been having this summer, especially at night.

While looking at my apple trees this week I noticed some funny little insects flitting around the leaves and fruit — they were apple maggot flies.┬áIt is the larval stage of this fly that causes brown streaks inside infested apples.

Apple maggot flies have a distinct pattern on their wings. You may not recognize it as a fly at first glance.

Normally, the early varieties are the ones that really get hammered by apple maggots. However this year, my early apples were free of those pests. My guess is that the flies took a little longer than usual to develop and were not around around in sufficient numbers to cause any noticeable damage.

Now that I’ve picked all of my very early summer apples, the maggots have moved over to the other later varieties that have apples still developing. The adult flies are looking for apples on which to lay eggs. The eggs will hatch into those pesky maggots that ruin so many apples.

The storm front moved through yesterday and the rain has ended. That gave me a chance to spray my trees this morning to knock back those apple maggot flies. I like to spray early in the morning when the air is calm and spray material is not being blown back in my face by wind.

There are other ways of controlling apple maggot flies that take more time such as trapping adult flies, or wrapping each individual apple to protect it from egg laying flies.

I suggest you spend some quiet time with your trees soon and look for apple maggot flies. If you find them, use your control method of choice. Your trees will reward you with pest free apples.
