Objective] To determine the effects of tobacco seedling density on the propagation of Aphidius gifuensis Ashmead., and to en-hance the propagation rate of A.gifuensis.[Method] Four densities (40, 80, 160 and 322 plants/dish) of tobacco seedlings were used to propagate A.gifuensis.Propagating quantity of tobacco aphids, parasitic rate and incidence rate of A.gifuensis, and production cost of propa-gation were investigated.[Result] Quantities of tobacco aphids, parasitic aphids and mummified aphids in each treatment had consistent cor-relation with tobacco seedling density.They all firstly enhanced and then declined with the increase of tobacco seedling density.There were great differences in the incidence rate of A.gifuensis.Density of 80 plants/dish had the best propagation effects.[ Conclusion] The research results provide theoretical basis for the propagation of A.gifuensis.
