The agent is a bionic ecdysone-type insect growth regulator, pests eat the chemical, the molting reaction occurs that begin to molt, because they can not completely molting and cause larvae dehydration, starvation and death. Contrasting with the mechanism of action of the agent for suppressing pest molting, the agent can be administered to the pest throughout the larval stage
