Four New Species of Scolytidae (Coleoptera) from Korea
Korean journal of applied entomology, volume 28, issue 2, 1989, Pages 57~60
Following four scolytid species were collected from Korea and described as new to science Polygraphus nobuchii sp. n., Scolytogenes puerarae sp. n., Dryocoetes carpinivorus sp. n., and Hypothenemus seoulensis sp. n.
Studies on the Effects of Systematic Applications of Several Insecticides on the Population of the Brown Planthopper, Nilaparvata lugens Stal. II. Some Properties of Buprofezin (Applaud) and Isoprothiolane (Fuji-one) in their Effects upon the BPH Population
Korean journal of applied entomology, volume 28, issue 2, 1989, Pages 61~68
To investigate the possibility of the BPH control by systematic application of insecticides, biological effects of buprofezin and isoprothiolane upon the BPH population was evaluated in the laboratory and pot. Both chemicals did not affect the developmental period of the nymphal stage with the applied dosages. When the buprofezin treated instar nymph was developed to the adult, adult's longevity was fairly reduced and such an effect of buprofezin was greater upon the younger instar nymphs. Residual effect of buprofezin was about 30 days in the pot. And it could suppress the BPH population when the younger instar nymphs were dominant age group in the population at the time of treatment. Isoprothiolane was also more effective for the suppression of the BPH population when the younger instar nymphs were dominant at the time of treatment. And it was expected that by buprofezin treatment in July the control effect of isoprothiolane against the BPH population could be maximized when it was treated to control the rice neck blast in late July or early August, because buprofezin could induce the biased population age distribution in which younger instar nymphs were main group at the time of isoprothiolane treatment.
Production of Extracellular Amylase by Bacillus thuringiensis subsp. kurstaki HD-1 and its Characteristics
Korean journal of applied entomology, volume 28, issue 2, 1989, Pages 69~75
The extracellular amylase production by Bacillus thuringiensis subsp. kurstaki HD-l in amylase production media and its characteristics were investigated. The amylase production was highest in the medium composed of 0.2% soluble starch, 1.0% Bacto-peptone, 0.3% beef extract, 0.3% yeast extract, 0.5% NaCl, 0.3%
, and 0.03%
. The amylase activity was inhibited by 50mM EDT A. The enzyme was optimally active from pH 6.5 to 7.0 at
, The specific activity of the enzyme in the ethanol precipitate was 2.01 units/mg, and the Km value was approxi-mately 0.8 mg/ml.
A Review of Blastobasidae (Lepidoptera) in Korea
Korean journal of applied entomology, volume 28, issue 2, 1989, Pages 76~81
A species of Blastobasidae, Pseudohypatopa longicoruntella sp. nov. is described as new to science and illustrated, and Neoblastobasis decolor (Meyrick) is newly recorded from Korea. The total of four species known for Korean fauna including the previously known species, Blastobasis sprotundalis Park and Neoblastobasis biceratala(Park), are briefly reviewed with new distributional data.
In Vivo Mass Production of Spodoptera litura Nuclear Polyhedrosis Virus
Korean journal of applied entomology, volume 28, issue 2, 1989, Pages 82~87
Mass production of Spodoptera litura nuclear polyhedrosis virus (SINPV) was carried out on massively reared host insects. The yield of SINPV was maximal with
PIBs per larva on the 8th day post inoculation, when 5th instar larvae were inoculated with
PIBs per ml, and 2 g of artificial diet was sufficient for food consumption of a larva. The moribund larvae were more suitable for handling and mass production of virus than the completely dead larvae. The larvae, when treated with methoprene (
), prolonged their larval period and consequently became bigger to result in higher yield(about 15%) of virus.
Food Attractancy of the Oriental Tobacco Budworm, Heliothis assulta, Larvae
Korean journal of applied entomology, volume 28, issue 2, 1989, Pages 88~92
The Oriental tobacco budworm, Heliothis assulta (Guenee), larvae usually feed on the hot-pepper fruits and young tobacco leaves or buds in Korea. This experiment was conducted t(} compare their attraction to their host plants including fruits of the sweet-pepper and solanum uk kwang, besides the other two mentioned above. First instar larvae were most attracted to the hot-pepper fruits. Flowers or leaves of the hot pepper plants were not attractive either. When the hot-pepper fruits were compared for attractancy, based on developmental stages, relatively mature fruits, just before ripening, were the most attractive. Their extract with or without 10% ethanol also gave similar result to 1st instar larvae or 2~4 instar larvae, suggesting a possibility that there is an attractant(s) in the hot-pepper fruits.
