Korean journal of applied entomology, volume 22, issue 3, 1983, Pages 174~180
Five species, Hypothenemus californicus, Coccotrypes carpophagus, Othotomicus angulatus, Tomicus brevipilosus and Xyleborus seriatus were recognized firstly from Korea. Two species of them, H. californicus and C. carpophagus were preserved at Life Science Museum of Brigham Young university in U.S.A. X. seriatus intercepted at Kobe in Japan from imported yew log which had shipped at Nampo in North Korea was sent by Dr. F. G. Browne in England. Thirteen recorded species were also examined in this study.

Ditylenchus destructor Thorne 1945 was found to be the causal organism of the new root rot disease of Panax ginseng, which occurred extensively in Dongseong area of Cheolweon-gun, Gangweon Province, Korea in 1982. Thirty-six percent of the investigated fields was damaged due to the potato rot nematode. Infected roots showed brown discoloration of cortex and suberization outside the cambium. Cortex of the severly infected roots became sponge-like in texture and cavity was produced in the central portion of the root. Only the severely infected ginseng plants exhibited sympotoms of sudden wilting of leaves. The number of potato rot nematode in such field soils was
soil, while there was no such symptoms on leaves if the number was less than 7.

The growth of germ tube of Fusarium oxysporum f. sp. cucumerinum was remarkably inhibited on the water agar treated with 100ppm of Fe-EDDHA, a synthetic iron chelating agent, whereas germination rate of microconidia did not show much differences compare with that of non treated water agar. Both of the germination and the germ tube elongation of microconidia were suppressed significantly in King's B agar by the bacterial siderophores produced by Pseudomonas putida. The highest germination of the chlamydospores was obtained in the soil added with
of glucose plus
of asparagine. The chlamydospores of cucumber wil fungus germinated about
in rhizosphere soil of 2 day-old cucumber seedlings within 48 hours, and the germination was enhanced notably in rhizosphere soil of 10 day-old seedling. But the rates of germination was not increased according to cucumber growth age after 10 day-old seedling. The effect of P. putida and Fe-EDDHA on the germination on chlamydospores in conducive soil was not pronounced in the non-rhizosphere soil added with nutrient. However, the germination was suppressed significantly both in rhizosphere soil and in rhizosphere soil added with nutrient. The suppression of chlamydospore germination was greater in the bacteria inoculated soil than that in Fe-EDDHA treated soil.

In 1981 Rice Black-Streaked Dwarf Virus (RBSDV) was severely occurred in Yeongnam area of Korea. The influence of RBSDV to rice plant was studied with two susceptible cultivars, Nagdongbyeo and Cheongcheongbyeo. The stunting rate was determined by the percentage of plant height of infected plants vs. healthy plants. When the rice plants were severely stunted by RBSDV, the yield components and yield were greatly reduced. The stunting of rice plants infected with RBSDV was caused mostly by the shortening of internodes in upper parts of the culm. The relationship between stunting rate of rice plants and yield was shown to have a negative exponential correlation. The regression equations of the relationship are experssed as follows: In Cheongcheongbyeo
, and in Nagdongbyeo
Bean Yellow Mosaic Virus and Cucumber Mosaic Virus Causing Mosaic Disease on Gladiolus in Korea

A mosaic disease of gladiolus has been commonly observed with an infection rate of
in the field. Bean Yellow Mosaic Virus(BYMV) produced veinal spreading lesions on Cheonopodium amaranticolor, veinal necrosis and severe leaf distortion on Phaseolus vulgaris 'Scotia' and mosaic on Vi cia faba. Cucumber Mosaic Virus(CMV) produced local lesions on C. amaranticolor, mosaic symptoms on Nicotiana glutinosa and Cucumis sativus. BYMV and CMV were transmitted by the green peach aphid. Purified BYMV and CMV had a typical maximum absorption at 260nm. In agar gel diffusion test, BYMV and CMV gave positive reaction with their homologous antiserum. The size of BYMV was 750nm in length, and CMV was 30nm in diameter.

Biological, physical and chemical characteristics of suppressive and conducive soils to ginseng root rot were investigated. Population of antagonistic microorganisms to Fusarium solani was much higher in suppressive soils than in conducive soils, whereas the numbers of Fusarium species were smaller in suppressive soils. Mycelial growth and chlamydospore formation of Fusarium solani were inhibited in suppressive soils. In the water extract of suppressive soils, lysis of germination tube and macroconidia of F. solani was occurred by antagonistic microorganisms at 4 hours after treatment. There were no significant differences in physical and chemical characteristics between supressive soils and conducive soils to ginseng root rot, however, clay content of suppressive soils was a little higher than that of conductive soils.
Studies on the Resistance and Races of Soybean-Cyst Nematode, Heterodera glycines, in Korea

Sixteen recommended soybean cultivars in Korea were tested for resistance to Heterodera glycines. The nubmer of females which developed on roots of cultivars were fewer on 'Hwanggeum kong' and greater on 'Geumgangdaelib'. But there was no resistant cultivar to Heterodera glycines. Four field populations of Heterodera glycines tested for ability to reproduce on five host differentials. Geographical differentiations of H. glycines were newly founded in Korea. These were identlified to race 1 at Hwasun, race 5 at Yangsan and Suweon and Unknown race(or race C) at Seonsan.

Thirteen species distributed over 3 genera of the subfamily Lithocolletinae are reported from Korea. Of them 8 species are new to the Korean fauna. Two genera, Hyloconis and Chrysaster, are recorded from the Asian continent for the first time. Fore wings of all the species and male and female genitalia of some ones are illustrated. Besides these Korean species, one North American species, Argyromiges ostensackenella Fitcher, 1859, is newly transferred to the genus Chrysoster.

In order to eradicate harmful insect by use of sterile male techniques, it is necessary to disperse about 10 times as many male insect as in wild condition. However, it is so difficult to discriminate male insect in pupal stage that usually the population are likely to be contaminated by female insect when that are released in field. The present study was conducted to establish a useful method capable of differenciating the male pupae of Stomawys calcitsans by means of measuring the pupal weight and length. The results were summarized as follows; 1. Male pupa was lighter and shorter than female and high correlation existed between length and width of pupa. 2. There was significant relationship between the length of pupa and width of adult 3. When the pupal sex of stable ay was identified by median of mean length and mean weight of the pupae, the Ratio of female to male was 1 : 1. 4 and 1 : 2. 2, respectively. Therefore, median of pupal weight seemed to be applicable for obtaining more number of male pupae.
