Methanol extracts from 79 domestic plant species in 41 families and the crude oil of one Japanese plant species were tested for their larvicidal activities against Thecodiplosis japonensis Uchida et Inouye, using filter paperimpregnated and insect-dipping methods. In a test with 10 mgtpaper, strong larvicidal activity (>90% mortality) was obtained from the extracts of roots from three domestic plants belonging to Ranunculaceae (Aconitum pseudo- leave var. eretum, A. carmichaeli and Clematis florida) and the crude oil of sawdust from a Japanese plant, Thujopsis dolabrata var. hondai (Cupressaceae). However, only the crude oil from the Thujopsis sawdust revealed strong larvicidal activity when tested with 5,000 ppm by insect-dipping method. It is concluded that the Thujopsis sawdust-derived materials could be useful as a new control agent against T. japonensis.

Larva and pupae of Prosimulium kiotoense and larvae of Twinnia japonensis were collected and reported from Korea for the first time. The genus Prosimulium, previously unknown from Korea, contains 80 species worldwide and 8 species are known in Japan. Species are separated into 3 species groups; hirtipes species-group (47 spp.), macropyga species-group (14 spp.) and magnum species-group (19 spp.), with which P. kiotoense belongs to the hirtipes species-group. The genus Twinnia, also previously unknown from Korea, contains only 10 species worldwide. In this study, I provide detailed descriptions and photographs of larvae and pupae P. kiotoense and larvae T. japonensis. Prosimulium kiotoense is characterized by pupa with gill of 16 filaments, cocoon amorphous and entirely covers the pupal body, head and thorax densely covered with microtubercles, larva with postgenal cleft apically straight, and hypostomal teeth with median tooth prominent. On the other hand, larva of T. japonensis can be characterized by labral fan absent, gill histoblast with 16 filaments, and hypostomal teeth with median tooth distinctly shorter than other teeth. In addition to descriptions for each species, a key to Korean Prosimulium and Twinnia is provided, with reference to the Japanese species and habitat information.

This is a report that we investigated the distribution of Pine Gall-midge (Thecodiplosis japonensis UCHIDA et INOUYE) along the main roads in the vicinity of Seoul. 1. The Pine Gall-midge around the districts of Seoul spread to East-Northern direction, Kwang-Ju, Yang-Su, Su-Pa, Bong-il-Chun and Ko-Chon etc. 2. The factors responsible to the dispersal of Pine Gall-midge seemed to be with the direction of the wind during the period of adult emergence. 3. The parasitic rate of Isostasius seoulis on the Pine Gall-midge was very low except $13.6\%$ at Su-Pa district.

This study on the genus Chordodes was based on the specimens collected from four areas in Korea during the period October 1988 to October 1992. As a result, a new species is described using a scanning electron microscope and conventional method, under the name of Chordodes koreensis. And It was identified that C. japonensis Inoue, 1952 is synonymous with C. ferganensis Kirjanova and Spiridonova, 1989. This genus is reported for the first time from Korea.

We determined how presence of heterospecific individuals in the vicinity of a focal individual affects the behavior of two critically endangered species of cranes on their wintering grounds at Cheolwon in the Korean Demilitarized Zone(DMZ). The Red-crowned crane, Grus japonensis, is larger than the White-naped crane, Grus vipio, and it dominates the White-naped crane in aggressive interactions. We showed that the dominant species increases foraging activity in the presence of the subordinate species presumably because of scrounging of the food from the subordinate. Because interspecific interactions may affect avian endangerments this behavioral findings should be taken into account when managing winter refuges for the two engendered crane species.

This study investigated tree vigor of damaged forest by Thecodiplosis japonensis Uchida et Inouye. In damaged forest by pine gall midge, the investigation result of damaged rate section (severe, moderate, light) indicated that severe stand showed higher value of electric resistance ($k{\Omega}$) than that of light stand, the investigation result of tree density section(crowed, middle, little) indicated that crowed stand showed higher value of electric resistance than that of little stand (the value of electric resistance at which low reading show high vigor tree and high reading low vigor tree). The crown width and DBH (diameter of breast height) of external factors showed lower value of electric resistance than that of small size. The results of comparative between Crown area and value of electric resistance in each stand were $13.4m^2$ in severe stand, $10.9m^2$ in moderate stand and $7.9m^2$ in light stand. Therefore, the tree which have big crown showed low value of electric resistance (below $15k{\Omega}$)that has high possible of survial.

Beauveria bassiana F-101, which has high toxicity toward Acantholyda parki as well as Thecodiplosis japonensis, was an isolate to develop an alternative control system against the major forest pests. Up to now, in B. bassiana, only one pr1 gene has been isolated and characterized. Therefore, we here reported the identification of a pr1-like gene, which would be a factor of toxicity from B. bassiana F-101. The oligonucleotides for the amplification of the pr1-like gene, were chosen based on the conserved regions of the subtilisin family enzymes, pr1 genes of B. bassiana and Metarhizium anisopliae, and proteinase K of Tritirachium album. The cloned PCR fragment had 1111 bp including 52 bp intron. The deduced Pr1-like peptide showed a low identity with Pr1s of entomopathogenic fungi such as B. bassiana Pr1 (BbPr1) and M. anisopliae Pr1 (MaPr1) as well as the proteinase K of T. album (TaPrK). Instead, the deduced peptide had a substantially high amino acid sequence identity $(>65\%)$ with the serine proteases of Magnaporthe grisea (MgSPM1) and Podospora anserina (PaPspA). These results, therefore, appear to suggest that the putative Pr1-like peptide of B. bassiana F-101 belongs to the subtilisin-like serine protease family and may be a novel gene.

In order to elucidate the metabolism of the systemic insecticide, phosphamidon(2-chloro-2-diethylcarbamoyl-1-methylvinyl dimethyl phosphate), treated to pine trees against pine leaf gall midges (Thecodiplosis japonensis Uchida et Inouye), $[vinyl,\;carbonyl-^{14}C]$phosphamidon was implanted into the trunks of 10-year-old Korean red pine (Pinus densiflora Sieb. et Zucc.) and Japanese black pine (Pinus thunbergii Parl.), respectively. This chemical was degraded very quickly in pine trees after implanting, as confirmed by TLC/autoradiography of the extracts of pine needles. Phosphamidon metabolites in phosphate buffer extracts of pine needles include the major metabolite, ${\alpha}-chloroacetoacetic$ acid diethyl-amide, ${\alpha}-chloroacetoacetic$ acid ethylamide, 3-hydroxy-N,N-d iethylbutanamide, acetoacetamide, and trimethyl phosphate. The metabolism within pine trees is expected to be similar to this. Based on these findings, it is believed that the major pathway leading to the metabolites would be related to the P-O-vinyl hydrolysis of the chemical structure.
