To explore the infect effectiveness of Esteya vermicola conidia shed from the conidiogenous cells to pine wood nematodes, an infectivity test was conducted from different methods, different strains and different conidia concentrations. The results showed that although the conidia shed from the conidiogenous cells, they are still able to infect pinewood nematodes. In addition, the conidia had better effectiveness on pine wood nematodes by taking immersion method than other treatments. The strains CBS 115803 had higher infect effectiveness among 3 tested strains. The adherence and mortality rate fell with the decreasing of the initial conidia concentration. These results could be used as references for application conidia to control pine wood nematode and laid basis for further researches.
