The Notch Leaf Miners/Malaysian Weevils are hitting my lychee trees. I have tried some Neem and also an organic chinch bug remedy (thinking if I can get them in the ground that will stop the cycle). Neither seems to work. Do you have any suggestions for controlling them?

Hi Fred!

We’ve actually got a whole page of information pertaining to the leafminer life cycle and controlling the little buggers! Check it out here: https://www.planetnatural.com/pest-problem-solver/houseplant-pests/leafminer-control/

It should be mentioned that mature leafminer larvae overwinter in the soil. By getting them in the ground you are promoting their life cycle to continue. I would suggest the introduction of beneficial predatory insects such as the leafminer parasite (Found here! https://www.planetnatural.com/product/leafminer-parasite-miglyphus/) and perhaps a trap crop-insecticide pairing such as spinach to help lure the leafminers out of the lychee trees. I would suggest using either Azatrol or SNS 203 to injure or kill the adults. Both can be found here!

Hope this helps! Good luck!

I am not having issue with regular leaf miners on the lychee, these are the ones that eat the edges of the leaves. They are also called Malaysian Weevils I believe.

I am having some issue with them on the citrus so I will look at the link.

thanks,
Fred
