Effect of Fusarium fungi (including F. oxysporum f. sp. allii and F. solani f. sp. radicicola) on the behavior of Rhizoglyphus robini CLAPAREDE and Caloglyphus sp. war studied in the laboratory. Both mite species showed varying degrees of attraction to Fusarium-infected rakkyo plants. They were also attracted to a sample of PSA culture medium of both Fusarium species. Adult females of both mite species were strongly attracted to F. o. a., but only Caloglyphus females showed a preference for F. s. r. Active nymphs of R. robini were attracted to both fungi, unlike hypopi. In Caloglyphus sp., the immature forms showed a preference only for F. o. a. Attraction to shake-culture filtrates was observed by using R. robini, and the mites showed a strong preference for the filtrates of both fungus species. They were also attracted to the steam distillates of culture filtrates, as well as to the ether layer of the distillates.
