Well, yes for a debilitated gecko, but not for a growing gecko.
Besides, I don't think crickets and waxworms can be compared like that. Here's a quote from some literature my vet gave me:
"Studies have shown that gut loading crickets with a diet containing at least 8% calcium fed for at least 48 hours prior to being used as a food item for reptiles and amphibians would produce a meal that had a Ca
ratio of 1:1 or higher (Allen and Oftedal, 1989). Crickets that received dietary supplementation of calcium of 8% or greater also had three times the calcium content of those that were dusted with calcium supplement but not gut loaded prior to being used as prey items (Trusk and Crissey, 1987)."
You can boost a crickets' calcium content by providing a high-calcium gutload. But you can't gutload a waxworm the same way, because all they eat is honey and bran.
