Altair Posted August 7, 2006 Report Share Posted August 7, 2006 Help, I don't know how but my terrarium has an infestation of rhizome worms. I don't know what they are but they make a hole on my plants rhizomes and start eating them from inside. I tried to use imidacloprid (confidor and provado) but it doesn't work. I dont' want to lose my H. tatei, 2 of 5 growing points are already gone. My nepenthes lavicola probably has one inside. What can I do? Immersion is useless because water can't penetrate inside their small holes and they have plenty of oxigene here. Quote Link to comment Share on other sites More sharing options...
Guest Aidan Posted August 7, 2006 Report Share Posted August 7, 2006 Imidacloprid usually kills most things. Have you tried application as a soil-drench? Although systemic, a spray application may not be good enough to get at the grub/caterpillar. Otherwise, you may have to try digging them out by hand!

I watered the plant with confidor solution 3 days ago and today I rip a dead tatei rhizome and found the pest you see in the pic alive and happy. If someone can identify them it'll be easier ti find a selective chemical product Quote Link to comment Share on other sites More sharing options...
MrAga73 Posted August 7, 2006 Report Share Posted August 7, 2006 Someone know how this stupid larvae is called so that I can do some researches? Thanks Mr_Aga Milan - ITALY Quote Link to comment Share on other sites More sharing options...
tonyc Posted August 7, 2006 Report Share Posted August 7, 2006 It looks like the larva of a sciarid fly (fungus gnat) to me. Quote Link to comment Share on other sites More sharing options...
Guest Sheila Posted August 7, 2006 Report Share Posted August 7, 2006 Similar but not quite the same. http://www.bio.scarletts.co.uk/Sciarid_Fly.html Fungus gnat larvae can nibble roots, but I have never known them to do damage like Altair is describing, besides they only really live in the soil rather than in the growing points of the plants Quote Link to comment Share on other sites More sharing options...
Altair Posted August 7, 2006 Author Report Share Posted August 7, 2006 it has legs so it may be a beetle grub I'm doomed Quote Link to comment Share on other sites More sharing options...

PlantaCollector Posted August 8, 2006 Report Share Posted August 8, 2006 In my opinion this is a caterpillar (probably moth's). Have you a higher-resolution image? Quote Link to comment Share on other sites More sharing options...
Altair Posted August 8, 2006 Author Report Share Posted August 8, 2006 no, it's the best pic I could take with my old sony DSCP-31 Quote Link to comment Share on other sites More sharing options...
Guest Sheila Posted August 8, 2006 Report Share Posted August 8, 2006 How many legs has it got Vale? if it has just six (three pairs), it is most likely a beetle larvae of some kind. Caterpillars have six real legs as well but they also have what are called prolegs, which are not real legs but look like them, they are cylindrical rather than segemented and are used for gripping and walking, this gives them the appearance of having several pairs of legs.

Altair Posted August 9, 2006 Author Report Share Posted August 9, 2006 OMG I found the pest name, they're probably Ephestia kuehniella larvae. I got them 2 years ago with the food of my birds. I've never tought they'll be dangerous for my plants too. A friend tells me about bacillus thuringensis (Thuricide, Dipel) but i found it only on amazon.com. Anyone know where to buy it in europe?

Guest il brettio Posted August 9, 2006 Report Share Posted August 9, 2006 Accidenti Vale, mi dispiace davvero! :cry: Quote Link to comment Share on other sites More sharing options...
Altair Posted October 29, 2006 Author Report Share Posted October 29, 2006 after months of suffering, my tatei dies. Pests killed also all my huge 5 years old P. vallisneriifolia (you can see it in the second picture. :'( The nepenthes lavicola stops producing pitchers but now it seem to be recovering quite well (near the prolifera in the second picture) Quote Link to comment Share on other sites More sharing options...
