The invention belongs to the technical field of coleoptera bean
weevil subfamily insect breeding, and particularly relates to a
gleditsia sinensis bean
weevil sectional type artificial breeding method based on host preference, and a breeding device comprises an egg period
insect breeding box, a double-layer
insect breeding box connecting table, an adult
egg laying box, a hollow attractant storage box, an opening gauze box cover and a top gauze box cover; mature and undamaged wild
gleditsia sinensis seeds are selected and put into a
larva feeding box,
gleditsia sinensis bruchid eggs are inoculated, larvae and pupae develop in the
gleditsia sinensis seeds, eclosion adults are transferred into an oviposition box,
gleditsia sinensis seeds are put into the oviposition box, the adults naturally mate and oviposition, egg particles are collected and transferred into a new
larva feeding box, and after the eggs are hatched, the
gleditsia sinensis bruchid eggs are put into the new
larva feeding box. The gleditsia sinensis seeds are replaced with gleditsia sinensis seeds for larva stage breeding according to the step 4, and circulation breeding is achieved. The method is easy and convenient to operate and low in cost, the
survival rate of the larvae and the
egg laying amount of the imagoes can be remarkably increased, large-scale continuous breeding of the gleditsia sinensis bruchid is achieved, and a stable and high-quality insect source is provided for scientific research tests.
