Life cycle of leaf miners

There are many leaf miner species affecting various crops. Problems with leaf miner have increased as a result of the use of pesticides: natural enemies are killed, allowing leaf miner populations to erupt into serious numbers. Adult leaf miners are yellow and black coloured flies, at most only several millimeters long. The adult female lays eggs by making holes in the leave, known as egg spots, by using her toothed ovipositor. Often no eggs are laid in these holes, but the plant exuding sap is consumed. These holes are known as feeding spots. Leaf miners also feed on nectar from flowers and honeydew. When the larva hatches from the egg, it right away starts to eat its way into the leaf. They tunnel down into the mesophyll tissue where damage is caused by extensive mines. The outer layers of the leaf and stalk stay intact. These mines lead to cosmetic damage, leaves drying out or even early defoliation. This can affect the yield. Indirect damage occurs when fungi or bacteria enter the feeding areas. Before pupating the grown larva cuts a sickle-shaped exit hole in the leaf with its mouthparts. The larva crawls out of the leaf, falls onto the ground and will pupate in the soil. An adult leaf miner will emerge from the pupa. Within 13 days the female can lay up to 160 eggs.

Those of us dealing with them feel the soundtrack should be more ominous.

Gotta love how the use of pesticides created a pest problem.

Does anyone know if miners can also affect citrus fruits ?

[darkvalleypgajaon]

[lindalee]

What kind of illness can this type of flies cause to human? I got bites so often by this type of flies, and did not realized it were leaf miners. what method should we use to get risk of the larva when it fail to ground? beside clean up all the sick leave? Thank you for sharing.

Gross, but amazing at the same time.
The music helps to make it more positive than negative.
So the leaf miners do exit the leaf after they have eaten?
So it means its fine to eat a leaf or pea-pod which has the mining tracks ? (ie: we can rest assure that the miners are no longer buried within?)

[SalinaHeartstone]

These keep infesting my tomato plants I hate em

[DasAntiNaziBroetchen]

They seem to hatch and immediately know how to use their new limbs. Insane.

[AnnLarsen-inuy]

Will horse chst ut leaf miners also pupate in the soil, outside the leaf? I thought they pupate inside the leaf.

[Cleanyshh]

Oh gosh. Can't believe your whole garden will then be filled with more eggs and the cycle goes on... Nightmare

[liliyasgardenchannel]

I squeeze the leaf and that's supposed to squish them.

[DevinTheGardener]

Here is a organic mix to try: Vegetable oil 2tsp - Water 400ml - Dishwashing Liquid 1tsp. I also made a YouTube video on how to get rid of leaf miners

[ayangjibrut]

best insecticide to control citrus leaf miners, info needed..

[yumi]

If you have just a few, you can actually cut them out of the leaf by breaking the thin membrane of the leaf with something like a mechanical pencil

Narrator: "an adult leaf miner will co.e out of the pupae."

Me:"No way dude I thought Jim Carrey was gonna pop out of that shi thats crazy."
