| Abstract: | The trial of controlling first generation Dendrollimus punctatus walkers withCytolasmic polyhedrosis Virus has been conducted in Chengcun town, Yangxi county,Guangdong province. The virus doses used in the three treatments are, respectively,15 G(PIB)/hm2, 75 G (PIB)/hm2,and 150 G (PIB) /hm2. The reductive rates of walker population are, respectively, 41.3%, 75.9%, and 80.4%, while that of the contrast plot is17. 1%. The reductive rate of the trial field is 75. 6%. The result of the demonstration trialbasiclly tallies with that of the field trial. |
