In order to establish the successive rearing system brush-footed butterflies (Lepidoptera : Nymphalidae) were reared in a room. Artificial diets were developed for a year-round rearing. Bu-diet was best to rear these butterflies among 3 kinds of diet used. The freeze-dried host plant leaf powder in diet was better than heat-dried one
in the growth of larvae. The rearing results were best in the diet C/N ratio was 1:1. The 24-hrs old eggs could be stored for 5 days at
or for 3 days at
and showed 75% of hatchability. On the other hand, pupae could be stored for maximum 15 days at
because the emergence of abnormal adults appeared much more as the cold storage period got longer. And the adult was able to be stored until 60 days at refrigerator without relation of nectar-sucking period before cold-storage and storage temperature. Also a simple artificial ovipositing kit was devised by
cm of petri-dish and a female oviposited
of eggs with adding the ether extract of host plant to this kit. The systematic successive rearing method of brush-footed butterflies in a room was completed.

Seasonal occurrence of the stink bug Piezodorus hybneri (Gmelin) (Heteroptera: Penta-tomidae) was monitored at a soybean field and the campus of Gyeongsang National University, Gyeongnam. Korea, in which host plants are less available for the bug with aggregation pheromone traps of Riptortus clavatus Thunberg (Heteroptera: Alydidae) in 2004. At soybean field, P. hybneri began to be attracted to traps from June 28, earlier than flowering stage of soybean plants. Number of P. hybneri attracted increased sharply after October 11. At the campus the bugs were not attracted to traps from March 21 to October 5, but began to be attracted since October 11. Difference in the occurrences in the two sites may suggest that the stink bug immigrates actively into soybean field to find host plant. P. hybneri that had been attracted to traps since October 11 was assumed to be diapausing adults emigrating to hibernation sites. There was no difference between sexes in trap catches. The fact that P. hybneri was attracted from June to late November may suggest that the aggregation pheromone of R. clavatus was attractive to both non-diapausing and diapausing adults of P. hybneri. The aggregation pheromone traps, when baited with 16.7+16.7+16.7 mg or 7+36+7 mg of (E)-2-hexenyl (Z)-3-hexenoate, (E)-2-hexenyl (E)-2-hexenoate, and myristyl isobutyrate, attracted significantly higher number of both sexes of P. hybneri adults than the live male traps baited with ten R. clavatus males and hexane control.

To investigate feeding behaviour of the greenpeach aphid (Myzus persicae) on several plants, DC electrical penetration graph (EPG) technique was used. We chose 5 plants including pepper, melon, cabbage, radish, and eggplant which were known as major host Plants of this species. This study was focused whether feeding patterns of the aphid were different and which plants would be the most preferable among 5 host plants. The time from initial proboscis contact with a each leaf until the first electrical contact, as a measure of the time taken for the stylet penetration, the time from electrical contact to the first potential drop as a time consumed until intracellular sampling, the number of potential drops per an hour during periods of regular intercellular pathway probing, and the time from electrical contact to tile first phloem specific pattern indicating the time taken to reach and attempt to feed upon the phloem were analysed. As a result, except the number of potential drop, there was no significant differency of feeding patterns among 5 plants. However, the feeding patterns related on host acceptability were observed more frequently from Pepper, radish, and e99r1an1 than melon and cabbage.

This study was conducted to investigate morphological characteristics and effects of temperature on the development of Piezodorus hybneri on soybean. The unibanded stink bug, Piezodorus hybneri, is a serious insect pest in soybean fields giving damage to seeds in pod and leaves of soybean lowering both quality and yield. Eggs were spherical and laid in two raws on the leaves and pods of soybean plants. Body lengths of females and males were 9.8 mm and 8.7 mm, respectively. Egg hatch rates were better in higher temperature within the range of examined temperatures, which ranged in
. The development periods of eggs at the temperatures of 20, 25, 30 and
were 10.7, 5.0, 4.0, and 3.0 days, respectively. Mean developmental periods of 1st, 2nd, 3rd, 4th and 5th nymphs at
were 3.2, 3.4, 3.4, 3.3 and 5.9 days, respectively. Development threshold and effective accumulative temperature were
and 65.5 DD (day degree) for egg stage,
and 322.8 DD for nymph stage,
and 386.4 DD from egg to adult, respectively. Oviposition began from 10 days after emergence at
, and the longevity of female and male were 52.5 and 38.2 days, respectively. Total number of eggs and egg masses laid by a female at
were 496 and 21.3, respectively, The longevity of adult female was shortened with increasing temperature, whereas the total numbers of eggs laid by a female were decreased.

This study was carried out to obtain information about a several environmental factors influencing on the bionomical characteristics of Protaetia brevitarsis and Allomyrina dichotoma, which have been used for an important traditional medicinal stuffs. The moisture contents of humus affected the oviposition of P. brevitarsis and A. dichotoma, showing a suitable condition in range of
. Very high or very low moisture condition in humus decreased the egg laying of P. brevitarsis and A. dichotoma, Also, moisture condition of humus was an important factor influencing on the egg and larval survival, egg developmental period, and feeding activity of P. brevitarsis and A. dichotoma.

The soybean varieties the bean bug preferred the least were Kwangankong, Namhaekong, Sunamkong, Sorogkong, and Anpyeongkong, and next to them was Pungsannamulkong, among 25 varieties examined. Myongjunamulkong and Eunhakong supported a good growth of the bug as the daily gains of weight of 3rd instar nymphs were 14,9 and 13.9 mg, respectively. On the other hand the bug on Punsannamulkong gained weight daily as little as 10.1 mg. On Pungsannamulkong the nymphal development of the bean bug took
days, about three days longer than those on Myunjunamulkong and Eunhakong. The survival of the bean bug on Punsannamulkong was 83%, slightly lower than those on Myunjunarnulkong and Eunhakong. It seemed evident that Pungsannamulkong have a non-preference type resistance to the bean bug.

The embryonic and postembryonic developments of Pierodorus hybneri Linnaeus were observed in 5 different rearing cages such as A (Cylindrical, 10 cm in diameter, height of 4 cm), B (Cylindrical, 14.5 cm in diameter, height of 2.8 cm), C (Rectangle, 6.5 by 6.5 cm in
, height of 10 cm), D (Cylindrical, 9 cm in bottom diameter, 11.5 cm in upper diameter, height of 10.8 cm) and E (Cylindrical, 15 cm in diameter, height of 7.5 cm) containing soybean and peanut seeds as feeding food, and sponge-water container under laboratory condition of
and 16L:8D. Egg duration was 6 days regardless of rearing cages. Hatchability ranged from 63 to 80% with the highest in B (14.5 cm in diameter, 2.8 cm in height) rearing cage. Instar duration was longer from 5 days in 1st instar to about 11 days in 5th instar. Nymphal duration showed 35 to 36 days with'3ut significant difference in rearing cages. Percent emergence was in range from 65 to 82% with the highest in B rearing cage. Adult longevity was 35 to 83 days for male, and 32 to 79 days for female, and was the longest in B rearing cage. Total number of eggs laid by female adult was in range from 38 to 86 with significant difference in rearing cages, and was the most in B rearing cage. Accordingly, the reproductive rate of P. hybneri for 1 generation was within 17 to 56 times, and was the highest in B rearing cage. Therefore, it could be concluded that B cage is most suitable for stable rearing of P. hybneri under laboratory condition.

Soybean seed injury was analyzed in the experiments that soybean pods were allowed to be sucked by adults of the bean bug, R. clavatus, and were picked with a specimen pin. While attack by the bean bug at podding stage of soybean caused the increase of empty pods and completely-undeveloped seeds, attack at full seed stage caused the increase of seeds wi distinct injury mark on seed-coat. The ratio of deformed seed was lower than those of injury-marked seed and undeveloped seed when attacked during all stages. In at full bloom stage hardly produced injury-marked seeds and deformed seeds. When the injured seeds were dyed with acid-fuchsine solution, stylet sheaths of R. clavatus formed on seed-coat were observed in 83% of undeveloped seeds formed under attack during podding stage and in 91% of injury-marked seeds formed during full seed stage. In pods injured with a specimen pin at full seed and full maturity stages, no healthy seeds could be obtained from the pods. And the more picked at full seed stage, the more deformed seeds were produced and the higher weight reduction of injury-marked seed occurred. However, pin-injury at full maturity stage didn't give rise to weight reduction of seeds.

In this study we tried to develop a biological method for evaluating environment using the potter wasps as an indicator. Wasp species in family Eumenidae, were collected from 13 locations including agricultural area using nest trap. The wasps collected were classified and selected candidate species as an environmental evaluation indicator. Seven species were collected and the Anterhynchium flavomarginatum was the most dominant species. The number of the nest of potter wasps was 12.8/m both in the non-fertilizer and the non-pesticide areas and 7.2/m in the general agricultural areas. The number of nests was 13.4/m in the location where the Degree of Green Naturality (DGN) was high (4.28) and it was 1.2/m where the DGN was low (1.00), suggesting that the index of both richness and diversity tend to increase in locations with more nests. Based on these results, A. flavomarginatum, Orancistrocerus drewseni (Saussure), Isodontia nigellus and Chalicodoma sculpturalis were selected as indicator species for the evaluation of environment including agricultural ecosystem. And a standard for grading an environment (I to IV) was made based on the occurrence, the total number of nesting and the species diversity of potter wasps.

This study was conducted to survey plant-parasitic nematodes and their damages on Codonopsis lanceolata Trautv at 116 fields of 15 major cultivation areas in Korea. Among the 9 plant-parasitic nematode genera detected in the fields, Ditylenchus citri, Meloidogyne hapla, M. incognita, Pratylenchus neglectus, Tylenchorynchus clayton were identified. M. hapla Chitwood showing the highest field infection rate of 61.9% followed by Tylenchus spp. 16.1%, Pratylenchus neglectus 7.8%, Ditylenchus citri 5.1%, and Helicotylenchus sp. 5.1%. Average field infection rate of root-knot nematodes in 2-year-old C. lanceolata was 67.0%, and the average plant infection rate was 60.2%. The average yield decrease rate was 10%. The damage rate by the root-hot nematode increased as the cultivation year extended in Jeonbuk province, and the damage was also higher in flat land than in mountainous areas.

This study was conducted to determine the effect of temperatures on the egg and nymphal development, adult longevity and oviposition of bean bug, Riptortus clavatus Thunberg, using Saealkong seed as food sources in fibrous nylon-tube at four different temperatures (20, 24, 28 and
). Hatchability showed the highest value of 100% at
and decreased with increasing temperature. Egg duration ranged from 7 days at
to 16.7 days at
. Instar duration was longer with increasing instar stage. Nymphal duration was 38 days at
, 30 days at
, 23 days at
, and 18 days at
Emergence rates to adult were 16, 41, 72 and 68% at 20, 24, 28 and
, respectively. Female adult longelity ranged from a minimum 20 days at
to a maximum 63 days at
, while the longevity of male ranged from 19 days at
to 60 days at
. Preoviposition duration was shorter with increasing temperature and ranged from 11 days at
to 5 days at
. Total number of eggs laid per female ranged from a minimum 21 eggs at
to a maximum 67 eggs at
. Consequently, the estimated lower threshold tempeatures of each developmental stage were
for egg, and 9.3, 12.7, 10.0, 11.0 and 8.7 for the 1st, 2nd, 3rd, 4th and 5th instar, respectively.

In Iksan, Korea, Parnara guttata Brener et Grey spend three generations per year, 1st generation adult emerged mid to late May from pupa developed from overwintered larva in weeds on bank around rice paddy field or on hillside and moved to rice paddy field to lay eggs on leaves of rice. The damage to rice by 2nd generation larva began to increase late July and reached peak from mid to late August. The 3rd generation adults were observed early to mid September and flew away from rice paddy field. There was significant relationship between the transplanting time and the occurrence of P. guttata in rice paddy fields. P. guttata preferred the rice transplanted in late season in paddy field. Insecticide treatment on late July about a week before the peak larval occurrence reduced the damage by P. guttata up to 91.2%, whereas the treatment on early August was a lot less effective reducing only 57.2% of the damage.

Courtship behavior of the sweet potato leaf worm, Aedia leucomelas L. (Lepidoptera: Noctuidae) was observed under laboratory condition. Behavior of antennal Probing and wing fanning in presence of opposite sex was observed in dark room. Both male and female exhibited similar behavior, fanning wing and raising antenna before male flew toward female. Some of moths began raising antenna 20 minutes into scotophase, and 20 minutes later both sexes started to exhibit spectacular behavior, fanning the wings intermittently in high frequency as if producing sound for attracting opposite sexes. They began mating about one day after emergence and mating activity was peaked from 4 to 6 days after emergence. Multiple mating was observed and the copulation lasted 207 minutes in average. There was an evidence that female emit sexual communication signal and male respond to it, and it seemed that the sound production is possibly a part of the courtship behavior of sweet potato leaf worm.
