This study was carrid out to investigate the distribution of forest insect pests in Junsanri-gol, Daewonsa-gol, and Georim-gol of Mt. Jiri. A total of 140 species of forest insect pests belonging to 44 families under 7 orders were collected in these areas: 59 species 16 families in Lepidoptera, 35 species 9 families in Coleoptera, 33 species 10 families in Homoptera, 4 species 3 families in Hemiptera, 6 species 3 families in Hymenoptera, 1 species of Orthoptera and 2 species of Phasmida. These were 85 species of 36 families under 6 orders in Daewonsa-gol, 67 species of 31 families under 6 orders in Jungsanri-gol and 56 speices of 27 families under 7 orders in Georim-gol.
Hibernation and Seasonal Occurrence of the Cotton caterpillar, Palpita indica(Lepidoptera: Pyralidae), in Watermelon
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 111~118
The population density of the Cotton caterpillar, Palpita indica (Saunder) larvae was gradually increased until 10th October and then decreased rapidly after that time at the watermelon culture of rain sheltered house. After 15th October, many larvae went to soil and molted to pupae for the hibernation. Most of pupae were found in pF 2.4 soil moisture condition, but none in pF 1.5 hydro-morphic soil. Most of the pupae were found below 5cm and there was no pupa below 10cm from the soil surface. The sex ratio of the overwintering pupae was 1.09 : 1.00. For the monitoring of the cotton caterpillar adults using sex pheromone compounds, different mixture ratios of each pheromone compound were investigated with (E)-11-hexadecenal and (E, E)-10,12-hexadecadienal. Seven versus three ratio of (I)-11-hexadecenal and (E, E) -10,12-hexadecadienal was more attractive than any other ratio, and then followed by 6 : 4, 8 : 2, 9 : 1, and 5 : 5 mixtures. As a result of monitoring with 7 : 3 mixture of (E)-11-hexadecenal and (E, E)-10,12-hexadecadienal, occurrence peaks of cotton caterpillar adults showed 4 times per year. The first time of adult appearance was late July in 2000 and middle July in 2001 and the highest number was collected on late September.
Oviposition and Feeding Preference of the Cotton caterpillar, Palpita indica(Lepidoptera: Pyralidae), in Cucurbitaceae
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 119~124
The adult of the Cotton caterpillar, Palpita indica (Saunder) laid eggs more on mature leaves than on aged and developing leaves. They laid more on leaves than on petiole and stem, and more on the adaxial than on the abaxial surface side of the leaves. Larvae of the Cotton caterpillar showed their preference in the order of the cucumber (Cucumis sativus), gourd (Lagernaria siceraria), watermelon (Citrullus lanatus) ＞ oriental melon (Cucumis melon L. var makuwa), wax gourd (Benincasa hispida), melon (Cucumis melo), star cucumber (Sicyos angulatus) ＞ sponge cucumber (Lufa cylindrica), cotton (Gossypium indicum). There were no distinct differences among varieties and lines that were collected and hybridized at the Gochang Watermelon Experiment Station in Korea. There was a positive relationship between the leaf area and the degree of damage by the Cotton caterpillar. The feeding amounts of the Cotton caterpillar excrement were gradually increased to 16-18 days after hatching, after that the amounts of excrement were rapidly decreased.
Prevalence and Seasonal Abundance of the Dominant Mosquito Species in a Large Marsh near Coast of Ulsan
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 125~132
Seasonal fluctuations in density of mosquito species were investigated at two cow sheds near to a large, reedy marsh with fairly polluted brackish water near the coast of Yongam-ri, Cheongryang-myon, Ulsan, Korea. Female mosquitoes were collected biweekly using Nozawa light traps from March to September, from 1999 to 2001. On average, 4,416.1, 5,505.9 and 6,863.8 females per trap night were collected from 10 species in 5 genera in 1999, 2000 and 2001, respectively. Among them, An. sinensis was most abundant (53.4% in species ratio), followed by Cx. tritaeniorhynchus (43.0%), Cx. inatomii (1.6%), Ochlerotatus dorsalis (1.3%) and Cx. pipiens pallens (0.5%). A malaria vector, An. sinensis and a Japanese encephalitis vector, Cx. tritaeniorhynchus were collected 3,663.3 females and 3,142.5 females per trap night from June to September for the years, respectively. According to the biweekly population changes at the area, Cx. inatomii which was dominant species in 1997, was the most abundant in the early July during 1999-2001.
Artificial Rearing of Red-striped Golden Stink Bug, Poecilocoris lewisi(Hemiptera : Scutelleridae) on Peanut : Developmental Characteristics, Host Plant and Oviposition Preference
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 133~138
To establish the successive rearing of red-striped golden stink bug, Poecilocoris lewisi Distant, developmental characteristics, host plant and oviposition preference were investigated. Raw peanuts were supplied to the insect as a substitute food at 25
5% R.H. and under 16Lㆍ8D photo regimen. Total developmental period was 48 days: 8.2
0.3 and 12.6
0.8 days for egg, first though fifth instar, respectively. The instar survival rate was 57.1% and the sex ratio was estimated to be 53 : 47 (male : female). Adult longevity was on the average 30.8 in male and 35.4 days in female, respectively. Egg of P. lewisi was globular (
1.8-1.9mm) with milky white in color The number of eggs oviposited per clutch was mostly 14. Pre-oviposition period was 25.8 days and mean frequencies of oviposition were 4.4. Female preferred to oviposit on the host plant when available, but oviposited on the artificial leaf successively when the host is not around. On the other hand P. lewisi preferred to suck the nectar of stem or fruit of Phellodendron amurense Ruprecht, Zanthoxylum schinifolium Siebold et zuccarini, Cornus officinalis Siebold et zuccarini and Cornus controversa Hemsley among the 18 plant species tested.
-treatment on Oviposition and Colony Development of the Bumblebee, Bombus ignitus
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 139~144
The effect of
-treatment on interrupting diapause of Bombus ignitus was examined to provide a means for year-round rearing of the bumblebee. When mated young queens were exposed to 65% or 99%
for 30 min daily during two consecutive days, oviposition rate increased to 75% and 77%, respectively, comparing 50% in
-untreated queens. At the same time, the days needed to first oviposition shortened to 17-18 days in
-treated queens, comparing to 30 days in
-treatment at the second day after mating was appropriate to the oviposition and colony development.
-treatment showed a positive effect on the oviposition and colony development, but less than them of overwintered queen in numbers of produced progeny. It can be concluded that
-treatment to B. ignitus is insufficient to produce commercial grade bumblebee colony in spite of its capability for promoting oviposition, because the treatment failed to form a big colony.
An Edible Alginate Microcapsulation of Entomopathogenic Nematode, Steinernema carpocapsae
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 145~152
Field application of the entomopathogenic nematode, Steinernema carpncapsae, is limited by its susceptibility to UV irradiation and desiccation especially at leaf spray control. This study was conducted to develop the control technique using alginate biocapsulation of the nematodes against the beet armyworm, Spodoprera exigua and the tobacco cutworm, Sp. litura that are normally infesting hosts above ground level. The alginate capsules including infective juveniles gave significant feeding toxicities to the larvae of the two lepidopteran species. The lethality followed a typical sigmoid dose-mortality pattern with increase of the nematode densities embedded in the capsules. Moisture content in the capsule was critical to the survival of the infective juveniles. More than 80% nematodes could survive above 10% moisture content remained in the capsule. Remaining moisture content within the capsule was dependent on relative humidity, ambient temperature, and capsule size, but not on citric acid reaction time during capsule formation. More than 80% of infective juveniles in the alginate capsules could survive in distilled water at 15
for 60 days. When these nematode capsules containing welsh onion extract as another phagostimulant were applied on the 3rd instar larvae of Sp. exigua infesting peanut plants, they resulted in about 90% control efficacy. These results indicate that the alginate capsulation can be used for leaf-spray agent of the entomopathogenic nematodes as well as for improved storage purpose.
Effects of Field Application of Spodoptera litura Nucleopolyhedrovirus to Control S. litura in Chrysanthemum
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 153~157
This experiment was conducted to investigate control effect of Spodoptera litura using nucleopolyhedrovirus in chrysanthemum seedlings of open field and plastic house. Values of LT
of treatment 1.0
PIBs/ml were 6.2-5.1 days in open field and 6.9-5.4 days in plastic house. Values of LT
were shorter in open field than in plastic house. Cumulative mortality was 100% in 1.0
PIBs/ml and also higher in open field than in plastic house. In chrysanthemum field, organic synthetic insecticide (endosulfan EC) killed S. litura larvae in 2 days after application. Motality of S. litura larva inoculated with S. litura nucleopolyhedrovirus (SINPV) 1.0
PIBs/ml was found out from 4 days after application and maintained during 14 days. Protection values of with SINPV 1.0
PIBs/ml after 16 days were 94.0% and 89.4% in open field and plastic house, respectively, and those of endosulfan 350 ppm were 91.4% and 88.6%, respectively.
Pathogenicity of Spodoptera litura Nucleopolyhedrovirus with Different Temperatures
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 159~163
This experiment was conducted to investigate pathogenicity of Spodoptera litura nucleopolyhedrovirus (SINPV) with different temperatures to mass production. In laboratory, LC
values of SINPV were 5.534
PIBs/ml and 4.l0
PIBs/ml in 1st instar larvae at 2
, respectively, but those were increased at 32
at 3rd and 5th instar larvae were showed the lowest value at 28
values of SINPV in 1.0
PIBs/ml were determined at various temperature conditions (20-32
). The result showed that treatments at 28
values, but treatments at 2
was relatively longer. Also LT
values was shortened in high concentration and young larva. LT
values are dependent on the temperature, viral concentration and larval instar.
Seasonal Occurrence of Smaller Clearwing Moth, Synanthedon tenuis in Sweet Persimmon Orchards
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 165~167
The seasonal occurrence of smaller clearwing moth (Synanthedon tenuis) was monitored with sex pheromone traps in sweet persimmon orchards in Gimhae and Jinju in 1998, 2001, and 2002. Results indicated that it occurred in two generations a year. The first generation of the moth occurred from mid-May to early July, and the second one_from late July to late September, showing the peaks in early June and early to mid-August, respectively.
Bionomics of Coleophora obducia (Lepidoptera: Coleophoridae)
Korean journal of applied entomology, volume 42, issue 2, 2003, Pages 169~171
The life history and natural enemies of Coleophora obducia Meyrick which is a defoliating pest of Larix leptolepis were studied mainly in Chungchongbuk Province. Larix leptoiepis was the only host plant of this pest. Coleophora obducia had one generation per you and the adults emerged from mid May to late May with a peak emergence around May 14th. The mean number of eggs in an ovary was 44.5 and most females oviposited one egg on each needle. The duration of the egg stage was about two weeks. Larvae passed the winter in a pouch made by spinning the needles. Pupation began in the late April, and the pupal period was two weeks on average. The natural enemies observed were parasitoids and predators.
