Post Egg production in 8 l plastic bottle
Hello,

this is my minimal egg production setup. I just put two hands full of BSF prepupae into the bottle, put insect screen over the opening and put it in the sun. Today I saw the first eggs. I gave them some cardboard, but they prefered to glue their eggs to the bottle and on the insect screen. Certainly not ideal, but it works with very little effort.

Cool, I love that simple experiment.

How long were they in the bottle before you saw flies?

How long after you saw flies did you see eggs?

What temperature/humidity would you say the bottles were in? Did you try to control temp/humidity in any way?

What part of the bottle did the flies lay the eggs in?

1-2 weeks, the oldest prepupae were collected 1 month ago.

About 2 weeks.

Temperatures were 12 - 26°C. I don't know about the humidity, there were many rainy days. The bottles get wet from outside, but no rain gets in. I gave some drops of water about three times during the whole time. I should do that more often, because the flies immediately started drinking. The flies only mate when the sunlight hits the bottles directly, in the shade there is almost no movement.

They glued them directly to the plastc bottle on the bottom, under a layer of dead flies, empty skins, prepupae and pupae. And one cluster was positioned in the middle of the insect screen at the opening. Maybe they like this material more for egg depositing than cardboard, I will experiment with that.
