Scale Insects Found in the Green Houses in Korea
Paik Woon Hah ;
Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 1~4
Since Kanda's paper on Korean scale insects in 1942, no work on scale insects has been done in Korea. The author has collected 8 species of scale insects in 5 green houses in Seoul and Suwon, of which 4 species, i.e., Chionaspis kentiae, Chrysomphalus aonidum, Planococcus kraunhiae and Aspidiotus hederae are new to Korea. Dominant species were Planococcus citri and Coccus hesperidum and common species to 4 green houses were Planococcus citri, Coccus hesperidum and Saissitia coffeae.

Choi Yong Chul ; Cho Eui Kyoo ;
Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 5~9
The experiment was conducted to investigate the physiological characteristics on 16 Isolates of bacterial wilt pathogen, pseudomonas solanacearum E.F. Smith, those obtained from infected stems of tomatoes, hot-Peppers and eggplants. PSA and Sucrose medium favoured by the most of the isolates, and various degree of gelatin liquefaction occurred by each of nine isolates those alble to liquefy gelatin among 16 isolates tested. The most of the isolates except one, did not reduce methylen blue. All isolates did not utilize lactose, saccharose, and starch, although all isolates utilize the galactose. The utilization of dextrin, esculin, glucose, mannitol, raffinose and salicin was depended on each isolate.

Studies on the Bionomics of the Gray Tiger Longicorn, Xylotrechus rusticus (L.) (Coleoptera: Cerambycidae)
Kang Jun Yoo ;
Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 11~14
Xylotrechus rusticus (L.) is an important pest of poplars in Korea. The bionomics of the insect were studied to give some scientific bases for a development of the sound control measures. This study was carried out in the field and laboratory during the period from 1968 to 1969. The results ostained are as follows; The gray tiger longicorn has one generation in a year and overwinters as a larva. The adult appears during periods from the middle May to the early July, with peak in the early June and the eggs were laid in a trunk from the early June to the middle July. The mean body length of the adult was 17mm for the male, 21mm for the female and about 20mm for the pupa. The average number of eggs in an ovary were about 172 and about 2mm in length. The larva of the insect feed on the cambium under neath the bark, the diameter of the adult exit hole was about 5-6mm and 5cm in depth.

Studies on the Canker of Apple Trees (Causal Organisms and their Chemical Control)
Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 19~23
Apple cankers caused by Valsa mali Miyabe, Botryosphaeria ribis Cross, Phomopsis truncicola Miura, are distributed in the main apple growing areas, Choong Chung Puk Do, Choong Chung Nam Do, and Kyung Sang Puk Do. According to the survey in 1970 that Valid mali is the dominant causal organism among the three in the most severely damaged area. Valsa mali and Botryosphaeria ribis were found in ail 3 provinces, however, Phomopsis truncicola was not found in Choong Chung Nam Do. Especially, Botryosphaeria ribis was most abundant in Chunwon of Choong Chung Nam Do. Effects of chemical control of apple canker caused by Valsa mali were tested both on potato dextrose agar with inhibition zones produced by the fungicides and relative growth of assay fungus of peridermis was treated with tile fungicides. Ifost effective was mercuric and followed by Lime sulfur, Hydroquinone sulfate, in general.

Five to seven day old pupae were irradiated with gamma rays, the mating ability, and competability of the irradiated males were examined. The results obtained are summarized as follows: 1. There is no difference in percentage of males that mated, nor in the maximum number of matings of the males, when individual matings were made, and fresh females were provided every day for his life time. 2. The average days for the first mating of the emerged were 1.5 days for the control, and 2.4 days for the males irradiated with 25 and 30 Krad. The average days between first and second mating were 3.0 days for the irradiated males, and 1.3 days for the control. 3. The average matings of a male were 1.2 and 2.5 times when 5 and 10 females were provided to a normal male respectively. No significant different in average numbers of mated female per male were observed between the normal and irradiated males. 4. To test the mating competitiveness of the irradiated and normal males (1:0, 1:1, 2:1, 1:2, 5:1, 1:5, 0:1) were confined together with five virgin females. The greatest reduction in hatching percentage was found with 5 : 1 : 1 (30 Krad) where
was hatched.5, The results showed that the irradiated males were not fully competitive with normal males, but if the reduced number of eggs produced by the female mated with irradiated male is considered, it might be used sterile male techniques in rice stem borer control.
Effects of Light on Reproduction of Gibberella zeae and Overwintering of Soil-Borne Conidia
Kim Hee Kyu ; Chung Hoo Sup ;
Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 31~35
1. Continuous light induced more conidia than alternating light and darkness treatment in isolate Chinju 1. Isolate Suwon 3 produced much more conidia on synthetic medium than Chinju 1 in light. Conidial formation in Suwon 3 increased remarkably with alternate light and darkness in 8 days incubation. 2. Light was essential for perithecial formation in Chinju 1. No matured perithecia were observed in Suwon 3 with any treatment. Abundant perithecia were produced in Chinju 1 but only perithecial initiation occurred in Suwon 3. Suwon 3 produced significantly more conidia than Chinju 1, while perithecial formation was reversed. 3. Conidial numbers in soil decreased significantly through the winter at 10, 30 and 50 per cent soil moisture, with the most striking decrease at 10 per cent levels, but the number recovered again beginning in March, regardless of the soil moisture. The above results provide us a useful clue to support the possbility the conidia may serve as a primary inoculum.
Studies on the Chemical Control of White-tip Nematode, Aphelenchoides besseyi Christie, before Transplanting

Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 37~40
Experiments were carried out to control white-tip nematode, Aphelenchoides besseyi Christie, during the period just before transplanting. The experimental results were summarized as fellows: 1: From a 12-hr to a 24-hr sled-soaking application into 500 times dilutions of Malathion
EC and Lebaycid
EC were highly effective than other emulsifierble concentrations of chemicals. 2) The water surface application of PSP-204
G and Terracurr-P
G were effective. 3: Root·dipping application of Sumithion
Ec and Nemagon
Ec were more effective chemicals than others.
Epidemic Outbreak of Blast Disease in the Resistant Variety of Rice, 'Kwanok'
Lee E. C. ;
Korean journal of applied entomology, volume 11, issue 1, 1972, Pages 41~43
1. In order to investigate the epidemic outbreak of rice blast disease on the resistant variety Kwankon in 1969, this investigation was undertaken as a basis for breeding resistant varieties. 2. The 16 isolates collected from Kyunggi area were inoculated at the 3-4 leaf stage on 12 Japanese differential varieties used for identifying races under greenhouse conditions. Out of 16 isolates 15 were identified as C race group and one as N race group. Of the 15 rates, nine were C-8, two were C-7 and two were C-1. Of the remaining two isolates, one was similar to C-1, and the other was similar to C-5. 3. It is concluded that the epidemic in the resistant variety 'Kwanok' was due to the occurrence of the C race group, which can infect the Chinese type varieties.
