Control effects of some insecticides were evaluated against the stone leek leafminer, Liriomyra chinensis Kato (Diptera： Agromyzidae) with the some different treatment methods. Insecticidal activities effects were estimated on the different development stages of the insects on welsh onion. The insecticides that controlled L. chinensis eggs with over 83％ efficacy were spinosad, dimethoate, emamectin, and cartap. The insecticides that showed over 87％ of larvicidal activity were dimethoate and cartap. Dimethoate showed 93.3％ insecticide residual activity for 3 days a(ter treatment as a foliar spray. For control of pupae, the insecticides that showed over 88％ of contact insecticidal activity were terbufos GR and cartap GR. Both dimethoate and cartap had high adulticidal activity with over 95％ control efficacy.
