Sorry to bring up an older thread, but it's become suddenly relevant to my situation and I was hoping for some specific insights.
I know I have (at least one, haha) parasitoid wasps in my room. I have only been able to find 2 "hatched mummies", but up until recently I was very systematic with my physical aphid removal. Upon discovery (about 2 weeks ago) I significantly relaxed my aphid control and accordingly the numbers have risen - a lot. It had gotten so bad by the weekend that I assumed it was a fluke and there were no living wasps left so I went on a smashing campaign (I actually collected hundreds of aphids in a small container with a couple leaves to inspect later).
This morning a wasp landed in my hand. It was tiny, smaller than a winged aphid, but I don't think I misidentified it. This reconfirmed that I do have a population.
My questions: How long does it take from egg to adult? I can assume I'm smashing a lot of larval wasps, but I also can't just let plants die while waiting for a critical mass of adult wasps to balance and overcome the aphid population. Since the aphids have become reestablished, I'm manually killing over 200/day. Do I need to put out sugar water or something for the adult wasps? I don't have many flowers if they are feeding on nectar or something. My large plants are also in a fairly cool location which I understand can slow/alter wasp development - should I move them?
I have yet to carefully inspect my container from the weekend, but as of right now it looks mostly like there are a handful of winged aphids, a lot of living ones, and a handful of dead ones - no obvious signs of wasps yet.
I just don't want to waste this opportunity because it would be nice not to worry about it! Unfortunately there doesn't seem much easy to find information on the internet.
Thanks in advance,
Peter
