Analysis of the Isozyme Loci of the Beet Armyworm, Spodoptera exigua(H bner)
Korean journal of applied entomology, volume 37, issue 1, 1998, Pages 19~22
Number of loci, allele frequencies, and subunit structures of 17 kinds of isozymes were analyzed in a laboratory strain of the beet armyworm, Spodoptera exigua (Hubner) to get genetic markers. These isozymes had 30 loci with 21 polymorphic (70.0% polymorphism); effective number of alleles per locus, average heterozygosity (H,), and inbreeding coefficient (F) were 2.52, 32.8%, and 2 1.0%, respectively.

Study on the Genetic Variation of the Mitochondrial DNA in the Beet Armyworm, Spodoptera exigua (H bner), Using PCR-RFLP
Korean journal of applied entomology, volume 37, issue 1, 1998, Pages 23~30
Restriction fragment length polymorphism (RFLP) of a DNA has been a useful tool for analyzing genetic variation. This research was performed to establish an RFLP analytic method on the mitochondrial DNA (mtDNA) of the beet armyworm, Spodoptera exigua (Hiibner). To do this, total size of the mtDNA was measured and polymerase chain reaction (PCR) primers were selected. Its mitochondrial genome size was ca. 16kb. From a serial PCR test of 29 primers refered to the compilation of Simon et al. (1994), 22 primers were selected to amplify its mtDNA fragments. These primers resulted in short (300-700 bp) or long (1000-2000 bp) DNA products which represented a total or partial sequence of each of CO-I, CO-11, Cyt-B, ND-1, 12s rRNA, 16s rRNA, and some tRNAs. PCR-RFLP was performed in some variable mtDNA regions with 8 kinds of 4bp recognizing restriction enzymes. Different populations from Andong, Kyungsan, and Sunchun did not show any restriction site polymorphisms but had some length variation in certain regions of mtDNA.
Genetic Relationahips of the Two Morphorogical Types of Myzus persicae(Homoptera:Aphididae) Collected from Tobacco Plants Based on Random Amplified Polymorphic DNA(RAPD)
Korean journal of applied entomology, volume 37, issue 1, 1998, Pages 31~37
Random amplified polymorphic DNA (RAPD) markers were used to analyze genetic similarity among 8 clones of apierous green peach aphid, two types (M. persicae Sulzer and M. nicotianae lack man) classified by their mo~hologi~cahla raters and host preference (Blackman, 1987), collected from tobacco plants. The genetic variation among these clones was evaluated by polymerase chain reaction amplification with 20 random primers. The higher GC contents of primers, the better in amplification efficiency of PCR reaction in general. The genetic similarities among eight aphid clones were analyzed from UPGMA (unweighted pair group average method) cluster analysis based on simple matching coefficient. The range of genetic similarity coefficients was 0.414 to 0.808. The most close relationship among the clones was similarity coefficient of 0.808 between the PG2 and the PG3 clone. The eight aphid clones analyzed were clustered into three groups by the genetic similarity coefficient. The first group, PG1, PG2, PG3 clone including in M. persicae type by their morphological characters and RED clone in M. nicotianae type was clustered at the genetic similarity coefficient of 0.643. The second group, GR1, GR2, BRN in M. nicotianae type was at the 0.636;and the third group was DBR clone in M. persicae type. The results did not indicate any correlation between m&-phological types (M. persicae and M. nicotianae) and RAPD polymorphism. We could not detect any obvious genetic relationships of the two morphological types of the green peach aphid collected from tobacco plants.
A Morphological Study on the Androconia of the Lycaenidae(Insecta: Lepidoptera)in Korea
Korean journal of applied entomology, volume 37, issue 1, 1998, Pages 39~48
To know whether there is any androconia on Korean Lycaenidae, studies were carried out with Korean Lycaenid butterflies for their types and distribution pattern with the aid of scanning electron microscope. As the results, androconia was observed from 8 species; Niphanda fusca (B. et G.), Pseudozizeeria maha (K.), Zizina otis (F.), Everes argiades (P.), Celasrtina argiolus (L.), Maculinea arionides (S.), M. teleius (B.) and Lycaeides argyronomon (B.). Androconia was not found only from males, and it was observed on both dorsal and ventral surfaces of fore wings and on ventral surface of hind wings. Androconia was found to be distributed mainly on the area between the median and anal venis. General structure of androconia on Korean Lycaenids was rather simple with laminar and foot stalk. However, 2 types of androconia were observed from 2 species, Pseudozizeeria maha and Everes argiades, while only one type was observed from other 6 species. The foot stalks of androconia on Niphanda fusca under the tribe Niphandini is located on the ventral surface of laminar and hidden from dorsal view, while one end of that on all other 7 species belong to the tribe Polyommatini is attached to the lower side of laminar and shown from both side.

A juvenile hormone binding protein (JHBP) has been isolated from the whole body homogenate of Galleria rnellonella final instar larvae by gel filtration. The isolated protein is homogenous as judged by column chromatography and gel electrophoresis in the presence and absence of denaturing agent. The JHBP has a relative molecular weight of 32 k by denaturing gel electrophresis and 28 k by gel filtration. The protein exhibits a dissociation constant of 3.9 x M for JH 111.
Survey on the Pests of Stored Garlic
Korean journal of applied entomology, volume 37, issue 1, 1998, Pages 65~71
Survey was conducted on the kinds and densities of pests associated with stored garlic collected from farms of major garlic production areas from 1994 to 1995 in Korea. Aceria tulipae, Rhizoglyphus sp., Ditylenchus dipsaci, and Tyrophagus putrescentiae were frequently detected with high densities and Tarsonemus bilobatus and Aphelenchus avenue showed relatively low detection rates and densities. Detection rate of A. tulipue was 38% in 1994, but the rate was 65% in 1995. Number of the mite ranged from 1 to 4,500 per scale. Detection rate of Rhizoglyphus sp. was 63% in 1994, but the rate was 13% in 1995 and average number of the mite ranged from 1 to 135 per scale in 1994. Garlics damaged by Rhizoglyphus sp. showed decaying symptom. T~rophagusp utrescentiae was detected from 22 farms among 32 farms surveyed in 1994 and from 21 farms among 39 farms surveyed in 1995. However, number of the mite on garlic scale was relatively lower than the other mites and its damages on stored garlic was not determined.

Damage of Garlic Gall Mite, Aceria tulipae(Keifer), on Stored Garlic and its Chemical Control
Korean journal of applied entomology, volume 37, issue 1, 1998, Pages 81~89
In a survey on the pests of stored garlic, an unrecorded gall mite in Korea was found to damage on garlic surface making stripe feeding injuries. The mite was identified as Aceria tulipae (Keifer) 1938, based on the morphological characteristics. Light microscopic and SEM observations on garlics fed by A. tulipae revealed that there was no gall formation by feeding but there was only surface damage symptom. The damaged garlic surface showed symptom of losing gloss in the early stage and the feeding traces under dissecting microscope. Brown stripes appeared in the middle stage of damage and the whole scale turned to dark brown and shrank in the later stage. When the mite infested garlics were fumigated with 3 g/m3 aluminium phosphide for 72 hours in airtight plastic boxes (1 m x 1 m x 1 m), the mortalities of mite were over 90% for Namdo garlics.
