Trauermücken?

Hello everybody,.

Although I found a thread on the topic of Sciaridae, wlko, but to the infestation of dormant tubers. I've potted my tubers in the last few days. I had a few handfuls of substrate from the previous year, which I have mixed in. The substrate has a very high proportion of wood, and I was very happy with it.
After repotting multiple small flies are noticed however, that flew around the pots and always again on the substrate landed. Maybe the insects in the old substrate settled? Since I have never had problems with Sciaridae I can't say for sure whether the insects to which. Somehow, they seem to be slightly larger than those on the images on the Internet.
Now to my question: Trauermücke larvae are a problem for non-sensitive species such as A. konjak, A. bulbifer and Typhonium venosum? If Yes, how can I best combat these pests? Should I out pot the tubers again and put in fresh substrate?

Otherwise, I'd still Calypso Bayer in the House. -> http://www.pflanzotheke.de/giessmittel-g...-804_12997.html

Greetings
Alex

So I've only read one nematode to the fight can use or the Earth heated in the oven.

New sub entered should you give them.
Sciaridae are a problem because the larvae the roots anknabbern(ist das richtig)

Should I also tuber in fresh substrate pot have already formed roots? I should also wash the tubers and have concerns that the roots while taking damage. Therefore a treatment with a plant protection product in this case, frankly I prefer.

Hi Alex,

are the pots out there?

look here, since findeast everything

http://www.eBay.de/Sch/nemagro/m.HTML?it...=p2047675.l2562

If you are outside the pots, I'd do anything, which disappear from alone, I have up to now no harm had by Sciaridae.
In the apartment, nervts just a skosh, had also just a invasion, also knew not where you came from, there were hundreds.
Having then last week at the above provider nematodes and yellow panels ordered, now does it look pretty good.

I think with the wash out and new, you're doing more harm than the Sciaridae transplanting.

Hi Alex,

repot little brings, if the infestation is already stronger because the Sciaridae immediately lay eggs in the fresh substrate friends. Usually the larvae not on fresh tissue go, except when there is no more than feed rotten material; the GNATS are just annoying in the apartment.

Yellow panels are abundant ineffective but as control agents as indicator, early detection of the infestation. There are many very good chemical control agents for acute attack such as E.g. Chlorpyrifos, you need to see only what is there and what is still prohibited.
I have no experience with nematodes, would be but sure times interesting to test out how fast and effective.


Love greetings

Michael

Hello

Thank you for your answers!

Then I'll not pot the tubers. The pots are outside on the terrace. Rotten or rotting material is not safe in the substrate. Only until the harvest of the tubers in fall's will have decomposes. If the larvae in this case - assuming I've understood your answers - don't go to healthy tubers they don't bother me, and I will be therefore no chemistry.
I was worried just because I in the lapping of it have read that the larvae of the tubers would go.

Greetings
Alex

I would never do soil into the oven to sterilize them. After that, it's just dead material.


Thus, you kill off all (useful) life. Thus, it is ideal for the resettlement of harmful organisms, such as fungi and similar.

I'm always BI58 for Sciaridae or but keep these nematodes.

To prevent Sciaridae, you can make a top layer over the substrate. Sand should prove to be very good.

As prevention, it helps to keep the substrate surface dry and pour only from below. This has an effect similar to the layer of sand mentioned by Stephan.

Matches are a simple home remedy for these Sciaridae. Just with the ignition tip down into the Earth plug. You do not tolerate the sulfur. I have the same problem with me. All are gone now from a window. If it helps in the long run I can not say unfortunately.

Sven, can you there more to say? Are you a match or several, possibly depending on the size of the pot in every pot?

Hello

so I am against these little beasts always Lavalit to the spreading of the surface. That prevents the mould at may be too damp substrate, dries incredibly quickly, looks good and the Sciaridae are not really thrilled. Otherwise, these little creatures are already a nuisance, especially their larvae and the damage that will be done.
I adopted this method my many succulents and it worked great. There is a "stronger" infestation in a propagation greenhouse there help repeat even two Spüstöße from a mosquito spray, then cover quickly and after 2 days, then the haunting is over.

Just everyone has his own idea of success.

MfG Uwe

Hey,
I put 1 or 2 matches in normal flower pots (10 and 12). previously I that Earth had them dry and after the cheating properly watered, so that sulfur is also equally distributed. I gave up after a week almost. I was then but too lazy to make the Woods out. After 2-3 weeks the sciaridae from the pots with the gone wooden but all. the beasts the other pots have chosen now. I have these 3 days then spiked. I can say unfortunately also still more not.

In larger pots, I'd put a match to every 10 cm.

You should try it also with matches I would happy about your result messages.

I have read me a little now and will try that sometime. What I've found out here, there are now also sulphur-free matches, with which it does not work because the sulfur is the vital component.

Greeting
Andreas
