Improved efficient white muscardine silkworm cultivating method

The invention discloses an improved efficient white muscardine silkworm cultivating method. The method includes the following steps that silkworms are bred, beauveria bassiana spore suspension is sprayed on the surfaces of the silkworms within the 0-2h after the four-instar moulting silkworms molt, the silkworms die due to attack of diseases after five days to six days, the dead silkworms are picked out for further muscardine, and the silkworms are aired or dried to obtain muscardine silkworms. The varieties of the silkworms are Haoyue, Taiyuan and Hang 7. The silkworm varieties poor in tolerance of beauveria bassiana are screened out to serve as the varieties special for white muscardine silkworm production, so that the infection rate of the silkworms is improved. The extreme early stage of the five-instar silkworms newly molting is selected as the optimal period for inoculating the silkworms with the beauveria bassiana, and therefore the infection rate of the silkworms and the yield of the white muscardine silkworms are increased.
