| Abstract: | The occurrence and the damage of white grub in sweetpotato field in Yixian and Xiongxian of Hebei Province were investigated during 2010 to 2012. The results showed that the white grub was widely distributed. The major species of white grub included Holotrichia parallela,A nomala corpulenta,H. oblita and A . exoleta. The incidence of sweetpotato roots damaged by white grub was lower than 10% normally, but it might exceed over 20% in a seriously damaged field,and even reached to 49.1%. The peak period for H. p aralle la was in mid to late of July,while they were in late of June to late of July and in late of June to early of July for A. c orp ule nta and A . e xole ta, respectively, base on the numbers of adults trapped by black-light lamp in Yixian. |
