    • Abstract：Not only the output of insecticide DpCPV is always afected by climate and circumstan ces ， but also af ected by the technology of production highly．Studies have been done on DpCPVHn indoors and outdoors for the Dendrolimus punctatus quanlity of every collection an d the inoculation concentration an d the inoculation frequency an d the harvest time． The optimal conditions of multiplication have been gained．Th e optimal inoculation concentration is 1× 1 07CPB／mL ．Th e optimal Dendrolimus punctatus larvae for multiplication are 4 or 5 instar larvae．Th e optimal CPV ingathering time iS 13th or 14th day after inoculation．Th e OUtdoor yield of each larva can be 7．5× 10 CPB ．It iS higher than other reports in China．It is very important to guide high output of DpCPV multiplication．
