%X the fungus metarhizium anisopliae isolation qu-m270 is a promising control agent for the wheat white grub (hylamorpha elegans burm.), a chilean scarabeid species whose larvae feed on roots of diverse crops and move in soil up to a depth of 25 cm . in this study, the vertical movement of qu- m270 conidias suspended in water was evaluated in three soil series from the b¨ªo-b¨ªo region (36¡ã32£¿ s lat; 71¡ã55£¿ w long), chile. soil was obtained using pvc pipes 30 cm long by 20 cm in diameter. conidia recovery was performed in a specific medium for metarhizium anisopliae, by counting colony forming units in 1 g of dry soil. the quella series (aquic durixerets) was more restrictive to the percolation of conidia, which were concentrated at the first 10 cm . with the arenales series (dystric xeropsamments), conidia were found below 15 cm and in percolated liquids. on the other hand, the mirador series (ultic palexeralf) had a uniform distribution of conidia at every depth
