Experiments on pupae

Community and Forum → Insects biology and faunistics → Experiments on pupae

I read how varying the storage temperature of pupae was used to change the color of hatched butterflies. Has anyone done similar experiments? My work is somewhat related to radiation exposure. As soon as I find enough pupae of some banal nymphalid in one place, I'm going to try to emit electrons with different fluxes and gamma quanta with different doses, and then bring out the butterflies and see what happens. Has anyone ever heard of such experiments? Otherwise, starting from scratch will require a lot of material (pupae) and will take a long time.

About 12 years ago, I did a literature review for a project in which they tried to kill all pests in wood for export by irradiation. Unfortunately, I don't have any data left. I don't know if something has been published. But I can say that even then there was a lot of work on the effect of radiation on insects. So look for databases, for RJ at least (there are online for some years).

Yakhontov A. A.-Zoology for teachers. Volume 1. Invertebrates; Moscow, Prosveshchenie Publ., 1968. In this book, the author describes in detail such laboratory "temperature" experiments on nymphalids (mournweed, urticaria, peacock's eye), there is even a color table of experimental specimens.

Yes, I have read this book, but I would like to see the results of experiments (photos of butterflies with changed colors) of forum participants (if they were conducted), and literature on the effect of radiation on the color, size or some other part of butterflies.

For some reason, it seems to me that in the case of radiation, the color correlation is unlikely to be traced- the changes will be random, since there will already be point mutations. And when exposed to the dark, various genes that are already present in the body are turned on.

Everything is not so simple, when exposed to betta particles of certain flows, the irradiated material warms up, so the effect is complex and I can't even imagine what will happen as a result of it. I'm not sure the pupae will survive at all. In general, I will try to try, otherwise you can guess endlessly...

Hm... Quite an interesting topic. This year I'm going to hatch about 30 bedstraw hawkmoth eggs, so I'll have to experiment too!

With radiation?! smile.gif

Sell weapons-grade plutonium. Expensive. Pupae will be happy lol.gif

of course, you can experiment with everyone in a row, but I think it's better to choose the species with the greatest color variability. As for temperature effects: I checked, the effect is obtained only if you are exposed to cold in the near future after pupation or directly at this moment. if the pupae were lying down for a couple of days, then even frost, even smoke) I am och. interested in the effect of radiation on color, I can donate a couple of Apollonius pupae to this experiment (they will pupate in a week) with the condition that if anything happens, you will take a picture and return the corpses))) my email address t00m@pnz.ru

I'm sorry, I'm an illiterate person... can exposure to X-rays cause color changes?

Once in my childhood, after reading various literature, I conducted an experiment on the pupae of cabbage whitefish. I collected about 50 caterpillars and when they pupated, I divided them into 2 parts. I put the first one on the bottom shelf of the refrigerator, and put the second one out of the window. Winter this year turned out to be very cold (just by the way), frosts reached 40 degrees.
At the beginning of March, I collected the pupae and hung them in the room in front of the window pane.
In April, they began to hatch butterflies. The fact that they shat all over my windowsill is a completely different story. The fact is that the color of butterflies was very different. The butterflies wintering outside were much darker than the ones from the refrigerator. Unfortunately, this was a very long time ago and I don't have any of these copies left.

Tell me, I'm only new to this business, but can caterpillars pupate in wood? (If they can, then what types)

Very well can pupate caterpillars of woodworms (Cossidae) As far as I know, there are about 4 types of them in the Moscow Region.

Is that all? And scoops can't?

I don't think so. At least I haven't heard of such types of scoops.

Scoops often pupate under the bark of dead trees and stumps, and their pupae are often found when searching for xylobionts.

And in the wood itself? I just had a chance-I gave a caterpillar of alder arrowhead (scoops )in the aquarium where it was kept, a rather thick branch of oak. Oan began to "dig in" there, gnawing wood. There she pupated. Is this normal or abnormal behavior?

Comrades, a very interesting topic, but unfortunately long forgotten. No one has experimented with such experiments by changing temperatures on swallowtails? I want to try, maybe someone will tell me some clever thoughts, give advice! I will be glad to hear any answers!!!
