  • 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.

  • Morphological characteristics and life cycle of Parnara guttata were studied from 2001 to 2002. Egg was hemisphere-shaped in pink. Larva was milky white or yellowish green color with 2.9-30.6 nm body length, depending on their developmental stages from 1 st to 5th instar. Pupa were grayish brown from 23.8 to 25.7 nm length, adults were yellowish brown color and body lengths were 17.4 nm and 16.2 nm and wing expanse lengths were 35.2 nm and 30.6 nm with female and male, respectively. At 25${\pm}$2$^{\circ}C$, each developmental periods was 4.5, 30.2, and 6.9 days with egg, larvae, and pupae, respectively. Also adult longevity were 10.1 for female, average number of egg was 205.5.

  • This study was carried out not only to investigate the toxicities of 12 registered insecticides on different developmental stages, but also to determine the sublethal effects on longevity and reproduction of newly emerged adult female and development of the next generation in the rice skipper, Parnara guttata. Fenitrothion, fenthion, cartap hydrochloride, ethofenprox highly suppressed egg-hatch. All insecticides treated showed high larvicidal activity on the 1st to 2nd instar larva. The insecticides showed higher larvicidal activities on the 5th instar larva were fenitrothion, fenthion, ethofenprox, fipronil, methoxyfenozide, tebufenozide and Bt. var. kurstaki. The sublethal doses of fenthion, tebufenozide, cartap hydrochloride, methoxyfenozide, ethofenprox, imidacloprid and fipronil shortened the longevities of newly emerged adult female from the treated larva ($3{\sim}4$ instar). BPMC, imidacloprid, ethofenprox, fipronil and methoxyfenozide delayed the preoviposition periods of adult females and decreased the number of eggs laid when they were treated at the larval stages of the previous generation. Ethofenprox caused severe sublethal effects on P. guttata offspring, completely blocking the production. All insecticides except fenitrothion affected the egg viability, and all eggs from the adult females emerged from the survivors treated larvae with imidacloprid or fipronil fail to hatch. IGRs, methoxyfenozide and tebufenozide showed an adverse effect on the development of next generation larva.

  • An preliminary study was made with special references on the insect fauna of Mt. Gyeryong during the period from mid-May to mid-September 1981. The results were obtained as follows; 1. 673 species of insects within 156 families of 20 orders were identified and listed herewith. 2. The 16 species are first records from Korea : Phaneraptera nigro-antennata (Tettigoniidae : Orthop.), Phraraortes kumamotoensis(Phasmidae : Phasm.), Nesogaster lewisi (Nesogasteridae : Dermap), Polymerus palustris(Miridae : Hemip.), Agrosteomela indica (Chrysomelidae:Col.), Monochimus sparsutus (Cermbicidae : Col.), Oberthiiria ialcigera (Bombycidae: Lep.), Alcis albiiera (Geometridae : Lep.), Proplepsis diazama (G eometridae : Lep.) Pandemis cinnamomeana (Tortricidae : Lep.), Hypenodes squalida (Noctuidae : Lep.), Hypolimnas bolina (Nymphalidae : Lep.), Ctenophora nohirae (Tipulidae: Dip.), Ortalotrypeta isshiki (Trypetidaedae : Dip.), Trypeta artemisicola (Trypetidae : Dip.), Ichneumom 8-guttatus ( Ichneumonidae : Hymenop.). 3. We could find a considerable number of Oriental fauna species, Lepismachilis nipponica, Nezara antennata, Parapolybia varia, Anthophora zonata, Parnara guttata, Byasa alcinous, Eurema laeta, Pieris canidia, Eizera maha, Kaniska canace, Danaus sita including two newly recorded species, Monochimus sparstus and Hypolimnas bolina.

  • In this paper, in order to select specialist butterfly species that inhabit Haneul and Noeul Parks, previously landfill areas, we verified the reciprocal relationships between nectar plants and butterflies. While we will design the butterfly habitats, this paper will provide the foundation data for selecting the plants. The completed survey indicated that there were a total of 5 families, 23 species and 1,129 individuals. Butterflies of the main action were feeding on nectar, and such behavior was 36% of the total actions. Therefore, these parks play an important role in butterflies feeding on nectar. The correlation between butterflies and the nectar plants' color was not significant; Therefore, it is not necessary to consider flower color when choosing plants to attract the butterflies. In addition, butterflies prefer naturalized plants for feeding on nectar. Thus, when creating butterfly habitats, there is no use in attracting the butterflies by classifying the naturalized plants and native plants. However, if some areas that are need to plant native plants such as Inkigofera pseudo-tinctoria, Lespedeza bicolor, Aster koraiensis make use it, there could be taken an advantage to attract the butterflies. According to the algebraic curve model of curve estimation regression analysis, we were able to classify the generalist species and specialist species by regression analysis. As a result, Colias erate, Artogeia rapae and Parnara guttata were classified as generalist species, where as Rapala caerulea, Pieris melete, Zizera maha and Celastrina argiolus were classified as specialist species. Rapala caerulea prefers hills and forest for its habitat; therefore, it is clearly distinct from Pieris melete, Zizera maha and Celastrina argiolus which prefer grassland for habitats. These results show that Rapala caerulea is high conservation value in a landfill area where is developing ecological succession from grasslands to wood lands. In conclusion, these research are able to contribute to select the target species and suitable species that consider a singularity between butterflies and nectar plants, when we are creating the butterfly habitats, moreover these research will contribute to maintain a stable habitats.
