Abstract

The invention discloses an application of graphene oxide in preparing feed for Lepidoptera and Diptera insects. Among them, the mass-volume ratio (μg / mL) of graphene oxide to feed for Lepidoptera and Diptera insects is 500:1-2000:1. The feed is prepared by the following method: preparing a graphene oxide solution, preparing a culture medium, dissolving the culture medium in the graphene oxide solution, and preparing a feed for dipteran insects based on graphene oxide. The graphene oxide-based feed for Lepidoptera and Diptera insects of the present invention can shorten the growth period of insects, improve the survival rate of larvae, increase the weight of larvae and pupae, and greatly reduce time and production costs in the actual application process .
