Would then be worth a try. Luckily, I'm complete this winter
from the Thrips. Otherwise, I had the already regularly on old leaves, just before the move in, or weakening plants. In addition, I have not had any plants here for years, which were regularly visited by the animals in winter, such as mountain palm and ivy. Even a small Dieffenbachie regularly had a problem with it.

Hello!
Hypoaspis you can always spread. I hope at least that you don't often have temperatures below 12°C in your living room.... but beware: they are dark colored and you can see them under the pots :D not that then someone refuses to go into the living :D room. Most thrips have the doll stage in the ground. These are eaten by the ground-grab mite. But now there are again two new trips that (as is said) do not make the doll rest in the ground.

I would then immediately think about how I want to do it with the other predatory mites.
cucumeris, swirskii, degenerans, limonicus.... Bags or stray goods... how warm it gets... I have plants with nectars or pollen so that a stable population can build up.... Questions about questions :icon_confused:

Hi Tom,

under the pots is already fine, and on the desk top they will probably not feel very comfortable anyway... I don't necessarily want them either, I don't want to conjure up dark spots in my books every time I turn the page.
Do you think that it is necessary to use more robbers, or can the Hypoaspis get a grip on the problem alone? Hopefully I won't have introduced the latest animals right away...?

12°C can probably be ruled out, it remains above 20°C. Rather problematic is the Temp Max., which can also climb to over 37 ° C in summer. And also the humidity can fall below 30% as long as I have to heat.

With amorphophallus and paphiopediles, the pollen supply is very limited. But as an allergy sufferer, I suspect that the pollen should have few problems in the diet, or am I completely wrong?

At Biohelp I also found Macromite against thrips, although they are actually too expensive for me. With Hypoaspis, only blood and bird mite is given as prey, if I remember correctly?

Thank you and best regards
Michael

Hello Michael,
Hypoaspis or macrocheles eat almost anything that crawls in the ground and is not too big. Mourning mosquito larvae and eggs, swamp fly larvae, thrip sdolls... which of the three predatory mites is the better one for you I don't know.... but I don't think they'll be very different at these temperatures.
I would use other predatory mites. At these temperatures, A. swirskii would probably be the best choice. Comes from the Mediterranean area and also tolerates slightly higher temperatures. Humidity below 30% is of course already critical. If the plants spray something, then the mites have something to drink and the moisture goes up around the plants. You don't have to bring your whole living room to 65%! What counts is the humidity directly on the plants. Get bags in time, there are feed mites and predatory mites in it and hang them between. Bags are actually meant for the fact that inside the predatory mites multiply and then always migrate to the outside. If you want to make the flood procedure at the beginning, it makes more sense to get scattered goods. There are more predatory mites in there. Spread goods immediately after receipt (!) which are very prone to dehydration in their cardboard tube (60% loss within 24 hrs are already possible). You can also put the stray goods in coffee filters and hang them in the plants, the mites then migrate into the plants quite quickly and you don't have all the sow in the apartment.

I haven't tried it myself, but if I still have it right in my head, stable populations only build up when there are pollen. There is also extra tube piston pollen to buy as predatory mite food. Or you can use chilli plants as forage plants that almost always bloom. Castor also goes is just a bit too big for indoor (on which you can breed super A. degenerans).

Hi Tom,

Thank you very much for your help!
As soon as I have potted all the tubers, I will get the Hypoaspis and A. swirski. Biohelp is right in Vienna.

I will also get pollen, as chilli plants seem unfavorable to me in case of thrips infestation. I accidentally got one this winter, she is already wearing one, but she had to leave now, since she is probably also a found food for thrips, have actually already found some on it (otherwise they are nowhere to be found). It seems to attract them like mango attracts spider mites, almost as an indicator plant...

The draining trays of the orchids, which are always filled with water (about 1.5 m2), may also help with regard to the humidity. To do this, the predatory mites would also have to change the plants, pests do this only very slowly.

I will report!

Best regards,
Michael
