The invention discloses an enhanced cultivation device for adult 
hermetia illucens and a cultivation method of the adult 
hermetia illucens. The device comprises a 
darkroom and a bright room which are in communication with each other; an outer cover of the 
darkroom is made of a breathable and lightproof material, the side surface of the 
darkroom is provided with a 
hermetia illucens 
pupa inlet, an adult fly-out opening connected to the bright room and an observation window, and a platform on the bottom surface of the darkroom is provided with a pupal 
larva container; an outer cover of the bright room is made of a breathable and light-transmitting material, and an adult fly-in opening, an egg receiving window and a 
halogen lamp are arranged on the side surface of the outer cover of the bright room; and a box for containing an egg inducing object is arranged in the bright room and is used for receiving eggs. According to the enhanced cultivation device and the ultivation method, pupation, eclosion and adult 
mating of the 
hermetia illucens are controlled in the darkroom and the bright room respectively, the biological characteristics of the 
hermetia illucens are followed, the eclosion rate of the 
hermetia illucens pupae is remarkably increased, the 
mating space is not limited by a containing container for pupal larvae, more living spaces and social places are provided for the adult larvae, and the 
mating rate and the 
egg laying amount are increased. Adults with different sources and generations in different darkrooms are hybridized through the movable bright room, excessive 
inbreeding is avoided, and 
offspring activity is kept.
