What's eating apple tree leaves

16 posts in this topic

I have little yellow flies in my apple trees. Are they responsible for the holes in the leaves? Any help on identifying this little fly would be awesome. Thanks

With no pics of the damage, it's a little tough to say what's causing it. Doubtful as flies generally produce maggots and maggots generally need to be on the inside of something or in damp conditions to keep their bodies moist. Otherwise they tend to desiccate rapidly Have included a couple links to potential leaf eaters. Hope this helps.

Apple maggots are the larvae of a fly that make little brown tracks in the apple and cause it to be lumpy and misshapen.

Spray with Sevin added to normal fruit spray.  Malathion isn't very effective against them.  Don't use the Sevin too early or the apples will fall off. 

If all else fails, try the 'ask a question"

Apple maggots attack the fruit not the leaves. There are some leaf miners that occasionally will attack leaves but they don't make holes as such, rather little tunnels that are between the leaf surfaces and show up as little trails when looking at the leaf, especially when holding them up to a light source such as the sun. A little tough to gauge the size and dimension from the photo but that appears to possibly be one of several fruit fly species. Had I thought it was an apple maggot fly, I would've posted this:

There is a nice pest management schedule for the home orchard as part of the first link I posted.

I just posted about apple maggots because you mentioned them.

Sorry del. Was addressing the fact the OP mentioned holes in leaves. My IPM background tends to make me bristle when it comes to applying pesticides and in particular insecticides improperly timed without a target species present, hence my mention of the pesticide schedule. We're looking at some potential major problems controlling soybean aphids as a result of people ignoring those two things in particular. It may result in the loss of whole families of chemistry that were once effective for their control. Once upon a time, I thought it was no big deal, wouldn't happen. After all these years, it's becoming a game of Russian roulette.

When I was still spraying my few trees in the back yard, I did it by the calendar.  Us little guys really can't do IPM.  I could barely get them sprayed every couple weeks as it was.

I heard the real reason you don't like Walmart is because on yer first day as a part time greeter, they had to keep dragging you out of produce because you kept hollering at the women to "grab this banana!!" :tired:

You would get apples in maybe 3 years.  Just pick one for zone 3 if in itasca.   Plant a dwarf/semi-dwarf tree.  Actually, plant two or three for best pollination. 

Put a hardware cloth fence around the trunk to keep varmints from eating the bark off in the winter.

    • My wife and I like to float down the Crow from Rockford to the Mississippi. Hardly anyone on the river except Bald Eagles. Found some nice chicken of the woods mushrooms last summer.
    • Trump got the information from Nunes. Nunes heads the House intel committee, but Nunes also was a member of Trump's transition team. Nunes then fed information to Trump (information that apparently nobody else on the intelligence committee has) about incidental observation of Trump and his transition team (a team that includes Nunes himself). 
    • A better question would be are you right?  Even the articles you link to don't really support your "most likely" assertions so you have to resort to everything is a lie as evidence, like Donald's twitter, and anyone that doesn't believe your alternative facts is an Obama luvin' librul. 
    • What projects have you worked on? Big or small lets see um. Anything, guns, boats, cars, Decoys.    I had fun reworking a few old Harley Golf carts. Didn't have any digital before shots to post. The carts I got were in very bad shape. Had to do a lot of fiberglass body work on them and some mechanical work to get them running. Just used boat seats as I didn't want to throw a bunch of cash at reworking the old seats and one cart had no seats at all when I got it. I took all the big chrome front bumper and bag bars off and glassed over the holes. Everyone had cracks in the front nose cones and rear ends. Not perfect but fun. Top picture is one of the nicer ones I started reworking.
    • Do you have any thoughts about what state you're heading to for this?  CO is draw only but there are lots of decent options available with 0 points. MT had leftover tags which is good because you missed the deadline already. WY has options you could draw. ND has passed. NM passed. UT not a good option with no points I think. ID may have some options but not certain. SD and NE may have some good options but I've never hunted either.   That's some basic info on states. Once you pick a state and get a tag it's really not complicated for the most part. Get elevated, glass up a muley, bed him, sneak in him without being smelled it seen, shoot him!   My son and I just found out we drew ND muley tags this year so we're pumped about that!
    • Just random ones I like. 1) Grand Marais fall. 2) HSO member Laker fishing. 3) Door County Wis.
    •   Yep and the Hawks won again!
    • Choosing 3 "best photos" is tough, but here are 3 of my favorites right now.  Cottonwood vs. Lightning Morel cluster  Pup in the snow
    • Missed the game but I guess I am glad I did. 9 games to go, still time to right the ship but at this pace the blues are going to pass us up.
