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.
