Asian gypsy moths and European gypsy moths were used as test insects to study the effects of different artificial feeding methods on the biological indexes of their growth and development. The results showed that the infection rate of the larvae was significantly reduced after the cooking of the Steam Kettle,and the pupation rate were significantly increased. The treatment of newly hatched larvae with gauze can increase the survival rate of early-larvae larvae and reduce the incidence of infection. Accordin...
