Boring pest never encountered before


#1

30 years+ growing in California. Recently moved to the Midwest and have encountered a pest I’ve never seen before. This pest bores a small pinhole into the stock and creates a swelling at the site. Any thoughts or advise is appreciated.


#2

@Hogmaster any thoughts here I’m at a loose without seeing the actual pest ?

There is a type of caterpillar that does that. Corn borer caterpillar is the name of it I believe.


#4

Thanks, Countryboy. I haven’t seen the critter, either; just the results.


#5

I cannot see it very weel (blind), and it is blurry. It looks like a ladybug larvae. Good thing :smiley: Do a google serch for ladybug larvae. Newborn


#6

Thanks, Swisha. I’ve seen those moths but the caterpillar seems too big to make that small of a hole in the stock. However, this area is heavy with corn fields so I think you have given me a good start on a solution to this problem.


#7

It is not a caterpillar.


#8

Need a better picture. Ladybugs do not make holes in the stem, neither do caterpillars. They just eat a big section at a time.


#9

It may not be a problem until you identify the bug. Don’t just go providing a remedy that may be bad for your beneficial bugs.

Mention of cornfields makes me think of cutworms. Look that up also and get a decent clear picture. :slight_smile:

Thanks, Latewood. The ladybug larva seems too large to make the hole that i’m seeing. I haven’t seen a lot of ladybugs around here, but we do have a lot of a similar bug that is referred to as some kind of Japanese beetle and it plays hell with the tomato plants. Another possible cause to look into.


#11

Yes, that’s been my experience. My biggest nightmare in California were those white moths and their caterpillars.


#12

Thought I had a nice shot of it. I’ll get back out there and try again. Might be the low resolution of the photo.


#13

@latewood If caterpillars don’t make holes why would they call it a corn borer caterpillar. Do a little research.


#14

@Swisha i suggest you read the title next to his screen name be careful challenging him in the open forum
Just a friendly piece of advice
Happy growing :v:️:cowboy_hat_face:CB

Nice advice John! @Countryboyjvd1971


#16

A little respect goes a long way here @Swisha


#17

Sorry for the lag. I seem to be restricted on posts. @Swisha @countryboyjvd1971 @latewood Thanks for all your advise. Short of dissecting a plant I think that the corn borer is the culprit here. Now to research a solution.

They eat chunks out of the side of a tomato. then leave at daylight. You come out and it looks like something small took a big bite, chunk whatever.

I have a commercial greenhouse; I think I have a clue. :roll_eyes:

p.s. We are talking about identifying the bug in the image.

Hi latewood,
I hope you can help me. I have plants outside and noticed a couple were leaning to one side. I took one out of the pot gently and noticed the whole side of roots was gone. Obviously something is eating them but I could not see what it was. What should I do. I’m so bummed. :disappointed_relieved:

Check for ants.
