Studies on Ginger Mosaic Virus
So In Young ;
Korean journal of applied entomology, volume 19, issue 2, 1980, Pages 67~72
A mosaic virus disease of ginger plant was investigated to determine its virus group on the basis of host range, physical and chemical properties, serological behavior and electron-microscopic morphology. The disease gave rise to yellowsih and dark-green mosaic on the leaves in the early stage and stunted all the leaves as well as rhizomes in the late stage. In the field about 43\% of the plants were observed to be diseased The disease was able to be artificially infected to the ginger plants by the sap and transmission as well as to 23 other species of plants which were known to be the CMV susceptible plants by the sap transmission; Chenopodium amaranticolar, Nicotiana tabaccum var. Havana, cow pea, cucumber, tomato,... etc. The dilution end point of the virus ranged
and the thermal inactivation point
. Serological test showed a positive reaction by a CMV antiserum. An electron microscopy of the purified virus showed that the virus particles were spherical with a diameter of
. Virus particles from the infected tissue were observed to be free or aggregated in the mesophyll tissue of artificially infected tobacco plant. The mosaic disease of ginger plants were conclusively suggested to the CMV group.

Some experiment were conducted to evaluate the joint toxic action of carbofuran(2,3-Dihydro-2, 2-dimethyl-benzofuranyl methyl carbamate) and diazinon (0.0-Diethyl-0-(2-isopropyl-6-methyl-e-pyrimidinyl)-0-thionophosphate) against 3rd-instar larvae of the common cutworm, Agrotis fucosa (Butler). Acetone solutions of carbofuran or diazinon or mixture of these two insecticides, were topically applied to the mesonotum of the insect in a constant volume of
per larva by means of Burkard microapplicator. Joint toxic action of carbofuran and diazinon for 3rd-instar larva of common cutworm was synergistic. The maximum synergistic effect might be obtained when the ratio of carbofuran to diazinon was 4.8 : 5.2.

The toxicities of some soil insecticides were evaluated in terms of the tolerance to various larval-ins tars of the common cutworm (Agrotis fucosa Butler) using topical application method in the laboratory.
values(ug/larva) were determined by the probit analysis and the tolerance-values were obtained with '
values for from 2nd-to 6th-instars/
values for first-instars.' The relative toxicities of the insecticides were 31so compared with the
values for the instars. The degree of tolerance was greatly increased as the larval instar advanced; the ranges of tolerance between the first-and 6th-instar larvae to the insecticides phoxim (Volaton), diazinon, chlorpyrifos (Dursban), carbofuran (Curaterr) and Mocap were 251.6, 126.6, 97.5, 44.3, and 18.7 times, respectively. The average relative toxicities of the insecticides for the instars indicated that the toxicity of phoxim was the greatest and following carbofuran, chlorpyrifos, Mocap and diazinon.

This experiment was carried out to investigate the life history of the Three spotted plusia (Chrysodeixis agnata Staudinger) in the laboratory in 1976. (1) Female deposited
eggs during the oviposition period which was
days. (2) Especially, larvae were distinguished with 5-instar type and 6-instar type. The egg period was 2 days and adult longevity was
days for female and
days for male. Larval period and pupal period were
days for the 5-instar type and
days for the 6-instar type. (3) Width of head capsule of the 5-instar type was
and this of the 6-instar type was
. (4) A highly significant correlation was recognized between the log-width of head capsule and the number of instar.

The experiment was conducted to culture callus tissue induced from foliage leaf of garlic bulb for the production of virus-free stocks and for the reduction of expenses for seeds, The following results were reached. 1. Linsmaier-Skoog basal medium containing 2,4-dichlorophenoxyacetic acid (2,4-D)
showed the most effective for the induction for the induction of garlic callus. 2. The growth rate of callus was the highest in Linsmaier-Skoog basal medium containing kinetin
3. The results of periodical assay of virus concentration in callus tissues showed that virus was almost eliminated by repeated transfer of translucent and soft tissue for eight generations. 4. When virus-free garlic callus tissues were transfered to Murashige-Skoog basal medium containing kinetin
and naphthaleneacetic acid
, the tissues were redifferentiated and formed plantlet.

Present studies were carried out to investigate the life history of potato tuber moth, Phthorimaea operculella (Zeller), under laboratory conditions in Suweon. Studies on its life-cycle on stored potato tubers in the laboratory showed that seven generations were reared in a year and the development from egg to adult was completed in an average of 49.4 days in spring at
., 21 days in summer at
., 26.1 days at
., and 39 days in autumn at
. The females laid an average of 101 eggs each, with a maximum of 242 and longevity of adults 17.6 days in spring at
., 8.1 days in May-September at
., and 13.3 days in autumn at

Egg Parasitism of Green Rice Leafhopper, Nephotettix cincticeps Uhler by Gonatocerus sp. and Paracentrobia andoi in Southern Rice Cultural Areas
Chang Y.D. ;
Korean journal of applied entomology, volume 19, issue 2, 1980, Pages 109~112
This study was carried out to investigate the distribution of egg parasitoids from green rice leafhopper, Nephotettix cincticeps Uhler, from the middle of August through the early September in southern rice cultural areas. The results were obtained as follow. 1. Four species of egg parasitoids, Gonatocerus sp. A and B, Paracentrobia andoi and Anagrus sp. are newly recorded from the eggs of green rice leafhopper. 2. Egg parasitism rates of Gonatocerus sp. were varied from
on an egg mass basis and from
on basis of egg. Percent parasitism rates by Paracentrobia andoi were
on an egg mass basis and from
on basis of egg. Gonatocerus sp. was dominant egg parasitoid in the parasitism rate than Paracentrobia andoi.
Studies on Cave Spiders of Korea ( I ) Historical Review and A List of Caves and Spiders
NAMKUNG JOON ;
Korean journal of applied entomology, volume 19, issue 2, 1980, Pages 113~124
In Korea, only a few cave spiders have so far reported, so little is known as their fauna. The author investigated on the caves, various part of this country to have taken up the study of these spiders, detailed report will be made in future, but for the present, has dealt with as follow; 1) As a result of the historical review of the study on cave spiders have been recorded 39 species of 27 genera belonging to 15 families, including 16 new species in Korea. 2) It were recorded that the name and location of 154 caves; 121 limeston caves, 33 lava caves which surveyed by the author. 3) A list of cave spiders made out about 100 species 60 genera belonging to 23 families. However there are considerable number of species which have not yet been identified and waiting for descriptions particularly in the troglobiontic species. Especially the Leptonetid, Nesticid and Cybaeid species are very important matrials for discussing the variatoin and lineage of species through isolation. 4) Species common to foreign countries are restricted to a few; 25 species of Japan, 2 species of Europe. There are not exist troglobiontic species, and most of them are trogloxenous ones.
