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.

The American serpentine leafminer (ASL), Liriomyza trifolii (Burgess), was fist found from a vinyl house planting gerbera in Kwangju area on January 26, 1994. To learn its distribution and damage pattern on crop plants, a nationwide survey was carried out at 293 vinyl houses from 25 cities/counties in six provinces. Its damage was found at 22 vinyl houses in Kwangju and Chinju areas. The range of leaves damaged by the ASL was 5-100% on gerbera, 40-70% on chrysanthemum, 20% on cherry-tomato, and 5-20% on celery. Host crop plants included gerbera, chrysanthemum, celery, cherry-tomato, watermelon, and pumpkin.

The genus Opius Wesmael, 1835 (Hymenoptera: Braconidae: Opiinae) generally parasitizes larvae of Agromyzidae, Anthomyiidae, Drosophilidae, Tephritidae, Ephydridae and Cecidomyiidae, of which 32 species are recorded in South Korea. In China, seven new species of the genus Opius have been known. Among them, Opius crenuliferus Li & van Achterberg, 2013 is reported for the first time in South Korea. Specimen was collected by sweeping in West Daeshin-dong, Busan, Korea. In this study, description, and diagnostic illustration of O. crenuliferus are provided.

The genus Rhogadopsis Brethes, 1913 (Hymenoptera: Braconidae: Opiinae), which mostly parasitizes mining flies (Diptera: Agromyzidae), has been considered to subgenus in the genus Opius Wesmael, 1835. However, according to having the derived wing venation and forming a monophyletic clade, the genus Rhogadopsis is elevated to generic rank. As results of faunal survey in Yeoseo-do, Jeonnam, South Korea, the male specimen of Rhogadosis obliqua were collected by sweeping. Diagnosis, description, distribution and diagnostic illustration of Rhogadopsis obliqua are provided.

The genus Phaedrotoma Foerster, 1862 (Hymenoptera: Braconidae: Opiinae) parasitize in larvae of flies, Tephritidae, Agromyzidae, Ephydridae, Anthomyiidae, Scathophagidae, and Drosophilidae, of which 12 species are recorded in South Korea. As results of our survey, Phaedrotoma rugulifera Li et al. (2013) and Phaedrotoma vermiculifera Li et al. (2013) are reported for the first time in South Korea. Those specimens were collected by sweeping. Descriptions, and diagnostic illustrations of P. rugulifera and P. vermiculifera are provided.

An experiment was conducted to investigate types of injury inflicted by the stone leek leafminer, Liriomyza chinensis Kato (Diptera: Agromyzidae) on welsh onion. A feeding scar made by an adult female was a hole round in shape, with diameter of 0.08 mm and 0.48 mm in lesion, resulting in a white spot, many of which often form vertical dotted lines on a leaf. Egg spots were oval with 0.1 ${\times}$0.14 mm in size, one or several of which often form a V-shape in group. Feeding by adults began immediately after emergence and was very active from 4th to 5th day. Oviposition was done from 2nd to 6th day after emergence. In both feeding and oviposition, they were more active in the day time. Larvae after emergence crawled up the leaf at first, and then moved up and down to feed on mesophyll. When in high density, they feed on leaf from leaf tip to bottom, and let the leaf die. Area of damage per one larva was calculated as 72.1 $\textrm{mm}^2$. The aged larvae escaped from the leaf in early morning, usually between 5 and 7 am. Most pupation sites were distributed near plants,5cm in soil depth and within 10 cm away from the plant. Pupae of L. chinensis overwintered 10cm below soil surface and emerged from early May to late June the next year Adults then moved to welsh onions near over wintering sites, nursery, transplanted, and levee.

The antennal receptors of the adult male and female of the American leafminer, Liriomyza trifolii (Diptera: Agromyzidae) was studied using the scanning electron microscopy. This antennal receptors were developed to accept the chemical or mechanical signal in the environment. The antennae of L. trifolii is 317.52 $\mu$m long and composed of the scape, pedicel, funicle, arista. Antennae located between compounds eye on the middle in the head. The result of SEM observation, four types of receptors were characterized and grouped into morphological classes: Trichoid, Basiconic, Coeloconic, Chetiform sensilla. Trichoid sensilla are located on the all segment. As a rule, female is more than male. This sensilla are long and slender hair with straight or slightly curved, and taper to a sharp point apically. Basiconic sensilla are observed only on the funicle. The number of basiconic sensilla in male and female are almost same in both sexes. This sensilla are long and thick hair with stright or slightly curved, and taper to a blunt point apically. Coeloconic sensilla are observed only on the funicle. This sensilla were showed a finger-like projections the peg apex. The number of basiconic sensilla in male and female are almost same in both sexes. Chetifarm sensilla are located on the all segment. This sensilla are needle-like, tapering sharply. Pedicel are more than scape. The number of Chetiform sensilla in male and female are almost same in both sexes.
