【Abstract】 The method of carbon agglutintion test (CAT) was used to investigate the relatoin of the wolf spider and its prey, rice leafroller, Cnephalocrocis medinalis and was fund that the rate of positive reaction of CAT was 91.49% while the rate positive reaction of double diffusion test was 70.21% in 47 samples, the sensitivity of CAT has increased 128 times than positive reaction of double diffusion test, and cut short test time from 24-48 hrs to 1 hr.The method included preparation of antigen of prey, preparation of antiserum, purification of antibody, preparation of carbon antiserum, collection and preparation of predator and carbon agglutiotion test.更多还原
