The invention discloses a method for feeding
dichocrocis punctiferalis on a large scale, and belongs to the field of
insect feeding. The method comprises the following four steps: collection and incubation of
dichocrocis punctiferalis eggs, feeding of larvas at the age of 1-3 of the
dichocrocis punctiferalis, pupation of larvas at the age of 3 to aged larvas, and feeding of adult dichocrocis punctiferalis. Spawning and collection of the dichocrocis punctiferalis are solved by
degreasing cotton, spawning capacity of single female dichocrocis punctiferalis is high, and the
hatching rate is high;and secondarily, by the method, newly hatched larvas are fed with tender corns, requirements for
nutrition of the larvas at the age of 3 are met, meanwhile, escaping of the larvas can be prevented, and a large number of larvas at the age of 3 can be provided for field
inoculation tests; and moreover, compositions of an artificial feed in the method are simple, materials are easily obtained, the cost is low, requirements for
nutrition of aged larvas can be met,
pollution can be avoided easily, feed change frequency is reduced, and the labor and time are saved. By the artificial feed, large-scale artificial subculture feeding of the dichocrocis punctiferalis can be carried out. The method has the advantages of high feeding efficiency, low feeding cost,
high survival rate of the dichocrocispunctiferalis and the like.
