After II weeks only one Aphelenclzoides specimen was recovered from pyrethrum, while a dense population was present on chrysanthemum. This result proves that pyrethrum is not a suitable host for the chrysanthemum leaf eelworm.enhttp://creativecommons.org/licenses/by/3.0/Journal Contributionhttps://doi.org/10.1080/00128325.1967.11662174
