Sorry Sally, but gardens are not the balance Nature intended anyway, ergo,
we have insect herbivores "we" consider pests.  By all means keep your
critter(s) alive as it will be good for your Karma, but killing all your
Manduca larvae will have little effect on the overall picture.
There are several wasp AND fly parisitoids of Manduca, but I don't think any
impede the eating machine.  They will prevent them from becoming adults, but
long after the damage to your plants is done.
Good luck with your tomatoes.
