Hornworm questions


New Member

Soon I will have 20 pupae from Manduca Sexta. (Hornworm)
I want to breed them for our reptiles because hornworms aren't available where I live.

So I have some questions on how to do this right!

I've read they can live succesfully on Rapashy Bug Burger. My partner works in a pet store and can get it for me.
He also sells Pangea Insect Grub (cheaper)

Will that also be fine as food? Wich one will be better?
Will the worms become green if fed this kind of food?

Also, I know I have to mist spray the pupae daily, but do I have to spray the moths and worms too?

And will the moths eat sugarwater? Hummingbird necktar isn't available here.

Pupae, moths and worms have to be kept at 13-15 hour light to prevent them going into diapause?

At what temperature do I keep pupae, moths and worms?

Any more tips and tricks for a succesful breeding?

Ok have no idea about the food but here is what I can answer, you don't have to mist the worms or moths. The moths will eat sugar water just fine, just make sure it's the right ratio. I think the hours are correct for your lighting but your temps shouldn't need to be higher than room temp. In order to breed the moths they must have a tomato plants right next to their cage or inside it. But you must collect the eggs before they hatch if they are laid on the leaves so they don't become toxic worms. That is all I know, good luck.

That helped a lot already! Thanks for your reactions!

I'll place the pupae in a closed plastic box with damp paper towels on the bottom, and the pupae on a dry layer of paper towels on top, wich they can make a mess on while emerging, and paper towels on the sides to climb on.
Will that be ok?
After emerging ill put them in a butterfly cage with sugarwater and a tomato plant.
