rumak Posted August 8, 2019 Share Posted August 8, 2019 Doing some light chopping in soil around our mango trees ( age 3 years ). Many of the trees have quite a lot of these buggers. Look the same as the ones that totally destroyed a lawn of mine in another location. Will they damage our trees ? So far notice nothing... can they eat the roots like they do with grass ?

Rotweiler Posted August 8, 2019 Share Posted August 8, 2019 My wife says they are 1st stage root eaters. Can kill easily, she says. Bury some pieces of yams laced with insecticide around the trees. They will partake and die. Link to comment Share on other sites More sharing options...

rumak Posted August 9, 2019 Author Share Posted August 9, 2019 22 hours ago, cmsally said: Dung beetle larvae ?? I have been reading up on the different types of grubs. (there are many, and they look similar) Here is one excerpt : " Depending on what kind of beetle grub it is, it may be feeding on decaying wood, manure or compost instead of damaging plant roots. It's hard to tell what kind of beetle grub it is unless you're an expert." According to what I've read, most of the species do not harm tree roots. They can however eat the roots of lawn grass, as what happened to my large yard one time. The worst beetle grub is the ten lined beetle grub which can kill trees. I do not think that is what we have. More likely larvae of the rhino horn beetle but maybe another kind. Will be easy to tell once they actually turn into beetles..... the rhino horn one being fairly large and distinctive. And as Ivor says they are not dangerous so will be left alone. Link to comment Share on other sites More sharing options...

As per my post above.... will wait and see . I think the reason we have these grubs is because we DO NOT use pesticides. Of course most of the farmers around here do. However, as a good friend of mine concedes, sometimes a pesticide must be used if otherwise the tree (or rice in his case) will not make it.

Denim Posted August 9, 2019 Share Posted August 9, 2019 Ah ..... while we are talking mangoes perhaps someone can answer my own question. We also have a three year old mango tree in our back garden. Doing well and a bit larger than rumaks. However, in the last few weeks it has grown bigger and put out a lot of new leaves. So far so good but about a week ago I noticed that a lot of these new leaves were lying on the ground around the tree. The strange thing is that the leaves have not come of the tree at the stem but look like they have been cut off with scissors ?? About half an inch of the leaf is left on the tree then there is a dead straight cut and the rest of the leaf is on the ground ? Does not look like the result of chewing and my wife and I can see no insects on the tree. The leaves only fall during the day. If I collect them all up at 6.00 pm then at 6 in the morning the ground is still clear. During the day another 20-30 will appear on the ground. Got us both stumped. Could it be birds ?

So far have not used anything but am removing the grubs and putting in a plastic container to see if the birds come. Just one hour ago so no results to report yet. Do you buy that product in Thailand ? here is link i found for anyone interested : http://www.tstanes.com/mobile/biomagic.html Thanks for the info .
