Genetic Divergence and Phylogenetic Relationships among the Korean Fireflies, Hotaria papariensis, Luciola lateratis, and Pyrocoelia rufa(Coleoptera: Lampyridae), using Mitochondrial DNA Sequences
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 211~226
Genetic divergence and phylogenetic relationships among the major Korean fireflies (Hotaria papariensis, Luciola lateralis, and Pyrocoelia rufa) were studied. A portion of mitochondrial COI (403 bp) and 165 rRNA (490~504 bp) genes were sequenced, and the GenBank-registered, homologous 165 rRNA sequences of Japanese fireflies were compared (27 species of Lampyridae, one of Lycidae, and one of Rhgophthalmidae). Greatest DNA and/or amino acid sequence divergence was found when P rufa, belonging to Lampyrinae was compared with H. papariensis and L. lateralis, both belong-ing to Luciolinae, confirming the current taxonomic status of the species. In the PAUP and PHYLIP analyses with 165 rRNA data, grouping of the two geographic samples of H. papariensis with H. tsushimana validate the use of generic name, Hotaria. Nevertheless, lack of sister-group relationship of the two geographic samples of H. papariensis renders further investigation on this group . Although the Korean and Japanese L. lateralis formed a strong monophyletic group, a substantial genetic differentiation was detected between them (2.9% of 165 rRNA gene sequence divergence). Finally, the geographic samples of Korean p. rufa strongly formed a group with Japanese p. rufa, warranting the use of generic name, Pyrocoelia, but the genetic distance observed between the Cheju-Island individual and all others requires further investigation on this subject. Summarized, this study supports the current taxonomic status of the Korean fireflies in that each respectively formed a strong monophyletic group with its own species or genus.

Fourteen species of the genus Gonocephalum and one species of the genus Opatrum (Tenebrionidae, Opatrini) from Korea have been previously recorded. They are taxonomically reviewed based on many faunistic reports and research papers. We also examined many specimens including voucher materials of the previous studies. Among the recorded species, G. sabulosum is excluded because it was misidentified for the individual variation of Opatrum subaratum. We couldn’t find any Korean materials of four species (G. japanum, G. bilinearum, G. outreyi, G. malayanum), and used the materials determined from other countries. Key to 13 species of the genus Gonocephalum, illustrations of adults and male aedeagus are provided.

Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 239~244
During 1999~2000 expedition to Mt. Changbai-san in China, twenty species of Gelechiidae were recognized. Most of the species, except Anacampsis popullela (Clerk), are known for the first time from Mt. Changbai-san, and nine species are newly known from China. Scrobipalpa atriplicella (Fisher and Roslerstamm) and Anarsia lineatella (Zeller) are unknown species from the Korean Peninsula. A new combination, Carpatolechia dehania (Park, 1993), comb. nov. is given.
Effects of Temperature on the Development and Seasonal Occurrence of Chrysopa pallens (Neuroptera: Chrysopidae)
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 245~250
These studies were conducted to investigate the effect of temperature on the development and seasonal occurrence of Chrysopa pallens Ramber, a predator of aphids. Mean developmental periods of C. pallens from egg to adult emergence at four different temperatures of 17, 22, 27, and
were 39.5, 32.0,25.0, and 19.8 days, respectively. The longevities of adult females of C. pallens at the four temperatures were 84.7, 79.6, 77.7, and 69.8 days, respectively, whereas the total numbers of eggs laid by a female were 973, 1085, 1637, and 1735, respectively. Egg hatchability, rate of adult emergence, and sex ratio of C. pallets were slighty higher with increased temperature with 84.1~95.9%, 67.6~86.3%, and 1:1. Under three humidity conditions of 35, 55 and 75% RH, the mean developmental periods of C. pallets from egg to adult emergence at the
were 26, 24, and 22.9 days, respectively, while the number of eggs laid by a female were 1042.8, 1526.5, and 1640.0, respectively. Oviposition of C. pallets usually began 5~6 days after the emergence at
. Then females laid ca. 30~40 eggs a day, reaching a peak of 80~90 eggs a day about 22~28 days after the emergence. Population fluctuation of M. persicae and A. gossypii showed the highest peak in late May through the mid-June, and the second peak appeared in early~mid-September. The adult occurrence of C. pallens by the light trap record started from mid-May, and show two peaks, in mid-late July and mid-late September in Chonbuk area.
Prey Consumption and Suppression of Vegetable Aphids by Chrysopa pallens (Neuroptera: Chrysopidae) as a Predator
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 251~258
These studies were conducted to investigate the prey consumption and suppression of cotton aphid and green peach aphid by Chrysopa pallens Ramber as a predator. The 3
instar of C. pallets fed on 29.8, 77.9, 133.6, and 155.7 individuals of apterous Aphis goussypii Glover a day at 17,22, 27, and 32
, respectively. A preovipositing female fed on 73.1 individuals, ovipositing female on 86.6 individuals, and adult male on 69.7 individuals of apterous Myzus persicae (Sulzer) a day at the 27
. The functional response curve of the larvae and adults of C. pallens to the densities of A. gossypii indicated Helling’s Type II: the consumption of prey by the C. pallens increased with the prey density but the consumption rate decreased. The attack rate of 3rd instar of C. pallens was the highest among the 2nd instar, 3
instar, adult male and adult female, and handling time was the shortest. The critical ratio of the predator vs. the prey to effectively suppress the population of A. gossypii by releasing C. pallets eggs was 1 : 4 on red pepper and egg plant, and 1 : 3 on cucumber. Release of second larval stave of C. pallens at the ratio of 1 : 30 of the predator vs. the prey controlled satisfactorily A. gossypii on red pepper, and 1 : 20 on cucumber and tomato. The three-times introduction of the eggs of C. pallens was as effective as four applications of insecticides from mid-June to late September.r.
The Status of Spot Damage and Fruit Piercing Pests on Yuzu (Citrus Junos) Fruit
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 259~266
This study was carried out to investigate the status of spot damage by fruit piercing pests and the kinds of these pests on yuzu (Citrus junos) fruit in Koheung, the most chief producing district of yuzu fruit in Korea, from ’97 to ’99. The extent of spot damage by fruit piercing pests on yuzu was increasing in recent years. This damage of fruits was severe in the lower canopy than the high one from ground and intercropping groves between yuzu trees had a greater damage to compare with single cropping of yuzu. Spot damage of yuzu fruit was occurred mainly from late September to early November when yuzu fruit is enlarging and coloring yellow. The blackish concave spot on yuzu fruit surface was appeared in 3 days after introduction of Riptortus clavatus into a netted cage containing one yuzu fruit and the diameters of this spot was 8.3 mm. At 10 days after introduction, this spot changed into milky-white with 9.2 mm diameters. One concave spot has contained oil cells by 17.7 and its external appearances has unchanged until harvest. The kinds of piercing pests of yuzu fruit were investigated with 3 orders, 16 families and 37 species. These pests were classified by 11 species of bugs, 5 species of hoppers and 21 species of moths. Among them, dominant species were Physopelta gutta, Halyamorpha halys, Empoasca vitis, Aedia leucomelas, Agrotis tokionis, etc. Macroglossum bombylans and Acherontia s쇼x are newly confirmed species as the fruit piercing moths in Korea.
Current Status of the Occurrence of the Insect Pests in the Citrus Orchard in Cheju Island
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 267~274
As the pest of the citrus in Cheju, 69 insect species and 5 animal species were investigated during 1996 to 1998. Of these, Panonychus citri, Phyllocnistis citrella, Aphis citricola, Aphis gossypii and Frankliniella occidentalis are major pests. Especially, F. occidentalis and Peridroma saucia are very important species because of increasing damage. The number of pests species injuring leaf, branch, fruit and flower of the citrus are 36, 16, 41 and 2 species respectively. The rate of damaged fruits by pests is 20.5% in 1997 and 18.6% in 1998 and the rate of bad quality fruits is 6.4% and 6.7% respectively.
Effect of Temperature on the Development of Bracon hebetor (Hymenoptera: Braconidae) Parasitizing Indianmeal Moth (Lepidoptera: Pyralidae)
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 275~279
Development of Bracon hebetor Say parasitizing Indianmeal moth (Plodia interpunctella (Hubner) was studied at five temperature conditions (17, 20, 25, 28 and 32
) under a photoperiod of 16 : 8 (L : D). Developmental period (mean
s.e.) of B. hebetor from egg to eclosion decreased from 28.6
0.50 to 9.3
0.09 days and 28.1
0.51 to 9.2
0.09 days for female and male, respectively, as the temperature increased from 17 to
. The combination model provided a good description of the relationship between temperature and development. The low temperature thresholds were estimated to be 14.0, 12.8, 15.1
for development of egg, larva and pupa. The thresholds for normal development (outside of the boundary layer of the development) were 14.0, 17.5,
for egg, larva and pupa, respectively, indicating that the larval stage is more sensitive to the low temperature than the other stages. The results suggested that the present B. hebetor population could be another ecological race adapting to the seasonal temperature conditions of this area.
Non-Chemical or Low-Chemical Control Measures against Key Insect Pests and Rats in the Ginseng Fields
Korean journal of applied entomology, volume 39, issue 4, 2000, Pages 281~286
Non-chemical or low-chemical control measures against key insect pests and rats in the ginseng field were studied from 1993 through 1999. Broadcasting chemicals beside the ginseng field in the oviposition period showed the same control effect on the adults of the Korean black chafer, Holotrichia diomphalia, as broadcasting at the ginseng ridge. Ginseng damage by adults of African mole cricket, Gryl1ota1pa africana, were reduced considerably by broadcasting chemicals beside the ginseng field. The larvae of wheat wireworm, Ectinus sericeus, were attracted effectively to potatoes in the ginseng field. Spreads of the mealybug, Pseudococcus comstocki, were very slow in the ginseng field, indicating that it is possible to eradicate the early colonies of Pseudococcus comstocki effectively. The rat repeller, Dekur
a significant control effect of rats in the ginseng field.
