What is this that burrowed into my tomato plant leaves???

Dear Everyone,

I have a pest which has burrowed under the upper most layer of my tomato leaves. I don't know what it is but I suspect that it will be harmful. So far it has left "lines" where it has burrowed. I have attached pictures.

Can anyone tell me what it is and how to stop it?

Thank you in advance for your help.

Roseamore

P.S. I have just sprayed the plants with garlic water to see if that will help.

They are called leafminers and you are right, the larvae tunnel around in the interior of the leaves.

Here's a thread where I wrote about them some (scroll down the page about half way)

Your garlic spray (or pretty much anything else) won't make a difference, because they are protected inside the leaves. You can just keep picking the affected leaves off.

Leaf miners are usually not a serious threat. Remember your "your tomato plants can have as much as 60% of its foliage affected with leaf miner without affecting the fruit or its growth."

What you can do is put down heavy mulch (beneficial anyway). That helps keep the leaf miners from completing the life cycle, which they do by dropping out of the leaf onto the ground and pupating in the soil.

Hi Rainbowgardener,

Thanks for the info; it was an eye opener. I did not know that there are insects that do this.

Seeing that the plant is young and only has three leaves will it survive me taking off an entire leaf and piece that are infected?

In that case, you could try to follow the squiggles to the end where the larva is hiding -- usually a slight bump and a dark shadow -- also visible as shadow when the leaf is held in front of a bright light -- and squish between fingers, cut out with scissors, or -- I experimented with using a paper hole punch this winter with some success.

Ultimately however, it IS easier to remove and discard the leaves because it's easier then to keep track of affected plants and leaves.
