Fruit & Orchards

HELP!!! Name This Bug

10 years ago

I have two peach trees and two nectarine trees that are affected by what I believe to be peach twig borers, though for all I know it could be that moth that affects stone fruit, or who knows what else.

A bunch of the new shoots started wilting and dying back. I cut all affected shoots and sprayed entire tree with a neem oil, as recommended by my local nursery.

Upon closer inspection, this is what I discovered...

Perhaps the supermodel analogy will help? Just like a woman does not need to look like a supermodel to be beautiful, your garden plants do not need to be pristine in order to be good producers. Free your mind from the shackles of advertising! ;) There really are a small number of pests that are common and damaging. And even the ones that are damaging need to show up in large numbers to be worth getting upset about. You will be exhausted in short time if you allow yourself to get upset at every hole you find in a leaf (especially since not all holes are caused by bugs) and every insect you see. Take it more like the justice system- the insects are innocent until proven guilty. Which means catching one in the act before deciding it is a problem. This will also save you a lot of money. I do not view bugs as nasty, dirty little things, but more fondly. They are amazing little things, very much alive and following their own purposes. Some are incredibly beautiful, and all of them are amazing. That last picture you have is a moth coccoon (technically a pupa). You can actually see the transition from caterpillar to winged insect in those, it is very cool. I do get rid of insect pests on my plants, but not from an emotional, angry place. Like with weeds, I do it because it must be done to get the plants to bear food for me. I'm not saying you need to think fondly on insects like me, I'm just putting out my way of thinking because it is different. Cheers!

Thank you so much! I found him in a bucket I was using for watering. He flew away after his close up.

I decided to look up thrips in my book about greenhouse pests and beneficials. It seems they reproduce both sexually and asexually. There are 5 instar stages, egg,2 larva stages, prepupal, pupal and adult. The hotter the temperatures, the faster they go from egg to adult. Apparently thrips are really attracted to blue so some greenhouse growers hang blue sticky cards. I was wondering if you could paint stakes blue, smear with vaseline and catch them that way? The blue stakes might not look to bad with daylilies either. Think that would work? I read on the robin that one lady plants white allyssum to attract beneficials that eat the thrips. She says it worked for her. 'The most beneficial spray they have that shows promise is Metarhizium anisopliae, an entomopathogenic fungi. When the spores land on the thrips, they break through to the inside using enzymes and mechanical force. The insect dies within a few days.' Marg

Borer? Nail them with spinosad.

The fly attacks fruits.
The chewer is a caterpillar, and entirely different creature.

I think that's an Oriental Fruit Moth larvae. 95% sure. Wait for one of the pros to confirm.

I am not a pro but I can confirm tmunson's answer as correct. You have OFM damage and its larvae. You didn't say if you have fruit on the trees but if you do you will need more than neen oil to combat OFM. Those little worms will destroy your entire crop.

I wasn't able to keep up my spray regime and each and every peach had a worm in it.

Very nice work with the camera.

I am not sure what the fly-like critter is but I saw a few of those in my peach trees this weekend. It does not look like the OFM adult pictures I looked up online.

And despite spraying regularly with Triazicide (best I have ever managed to keep up a regular spray schedule despite the rain), I have now an outbreak of OFM in my peach trees. What do you do when the scheduled sprays are not working? What is the 'go-to' insectacide to combat a spray failure?

So, I guess the consensus is that it's OFM rather than Peach Twig Borer. Either way, I guess I need to put the neem oil away and get Spinosad or Sevin?

I was reading about the spray schedule, and since I wasn't monitoring them with traps, how do I know when to spray?

Should I do one of those Bayer systemic insecticides, too? (Is spinosad systemic? I'm reading conflicting data)
