Feeding ecology of endangered Korean endemic miho spine loach, Cobitis choii, was investigated in Jicheon Stream, Geumgang River, Korea to provide ecological characteristics and baseline data for its restoration. C. choii is active during daylight hours above sand from March to October when the water temperature exceeded $13^{\circ}C$, but tended hibernate in the stream bottoms (sand) in the winter months (November~February) when the water temperature was lower than $13^{\circ}C$. They fed (index of relative importance, IRI) mainly Diptera (69.9%), Copepoda (23.2%), Arcellidae (2.3%), Branchiopoda (2.0%) and Ploima (2.0%). And their small juvenile (age 0+) fed mainly small size, Ploima and Branchiopoda, however, they ate mainly large size, Chilonomidae, while growing to adult fish (age 2+~3+).

The cattle liver flukes were collected at daughter house and classified with gross morphology. The hepatica type was only 14 flukes (4.7%) and the gigantica type was 284 flukes (95.3%) among total 298 flukes collected. In order to determinate the intermediate host of the flukes, artificial infection with the miracidia to snail hosts, Radix auricularia and Austropelea ollula, were successfully carried out, but the development in the later was terminated at the sporocyst stage. Intermediate host of the cattle flukes used to hibernate in deep part of the stubbles of rice pady. The number of A. ollula that has been collected from a rice stubble was ranged 0 to 19. Their mean number was 7 snails per the stubble. In artificial infection with miracidia, the reasonable number of them were 1 to 9 and the snail size was 2 to 5mm in length. The productivility of metacercaria in the intermediate host was observed. The metacercarial production per snail was ranged 5.5 to 48.0 per one miracidium.

Extensive previous studies on taxonomy, behavior/bionomics and control of Anopheles sinensis are reviewed and summarized. Recent molecular identification revealed that the population of An. sinensis complex includes An. sinensis, An. pullus, An. lesteri and at least two new species, and An. yatsushiroensis is synonmy of An. pullus. An. sinensis is the main vector specie of vivax malaria in Korea. Larvae of An. sinensis breed in wide range of habitats which are naturally-made clean water, stagnant or flowing; main habitats include rice fields, ditches, streams, irrigation cannals, marshes, ponds, ground pools, etc. Their host preferences are highly zoophilic. Human blood rate is very low ($0.7-1.7\%$); nevertheless An. sinensis readily feeds on man when domestic animals are not found near by. They feed on hosts throughout the night from dusk to dawn with a peak period of 02:00-04:00 hours; they are slightly more exophagic (biting outdoors); much larger numbers come into the room when light is on. Main resting places are outdoors such as grasses, vegetable fields and rice fields. A mark-release-recapture study resulted that $37.1\%$ was recaptured within 1 km, $29.4\%$ at 1-3 km, $21.1\%$ at 3-6 km, $10.3\%$ at 6-9 km and $2.1\%$ at 9-12 km distance. An. sinensis hibernate outdoors (mostly under part of dense grasses) during October-March. At the end of the hibernation period (March-April) they feed on cows at daytime. Until today any single measure to effectively control An. sinensis population has not been found. Indoor residual spray with a long-lasting insecticide can not reduce vector population densities, but shorten their life spans in some degree, so contributes to malaria control.

Habitat characteristics and feeding ecology of Iksookimia pacifica were investigated in this study to provide baseline data for its ecological characteristics in Bukcheon (stream), Goseong-gun, Gangwon-do, Korea. The main inhabit of I. pacifica was found to be sand bottoms of Bb or Bc river type with slow water flow. Based on studies of their habitat preferences according to age, their preference for sand bed was the same. However, their preference for depth and velocity was different. When their age was increased, their depth preference was also increased ($24.9{\pm}17.61cm$ for 0+ year, $69.6{\pm}30.32cm$ for 1+ year, $82.4{\pm}33.30cm$ for 2+ years, and $90.0{\pm}31.55cm$ for $3+{\leq}$ years). The water velocity was found to be 3.8 ~ 4.0 cm/sec for ages between 0+ and 1+ and 6.0 ~ 7.3 cm/sec for ages between 2+ and $3+{\leq}$. They were active on sand from March to November. They would hibernate in sand during the winter season. During the day from 12 pm to 24 am, they were highly active with high food consumption. Their main food sources analyzed with index of relative importance (IRI) include Chironomidae (76.7%), Simuliidae (10.3%), Rotatoria (7.3%), and Arcellidae (2.2%). Their juveniles (total length 20~40 mm) would feed on small-sized preys such as Rotatoria, Copepoda, and Arcellidae. Older I. pacifica would feed on big-sized preys such as Chironomidae and Simuliidae.

The feeding preference of cigarette beetles, Lasioderma serricorne F., was tested using various leaf litters. The number of the trapped L. serricome was 45.25$\pm$10.44 at flue-cured leaf tobacco, Nicotiana tabacum L., 23.50$\pm$6.0 at chinese juniper, Juniperus chinensis L., 1l.75$\pm$4.99 at oak, Qqercus acutissiuma C., and 1l.50$\pm$2.52 at rice-straw, (Oryza. sativa L.). The response of oviposition was 93.20$\pm$26.22 at flue-cured leaf tobacco, 53.60$\pm$11.82 at chinese juniper, 48.20$\pm$20.90 at oriental arborvitae, Thuja orientalis L., 31.80$\pm$18.10 at cherry-tree, Prunus serrulata var. spontanea M., and 29.40$\pm$13.7 at rice-straw. However, the oviposition was respectively low at gingko, Ginkgo biloba L.,(5.40$\pm$2.97), turf grass, Zoysia japonica S., (5.20$\pm$13.7), and oak (3.00$\pm$l.41). The augmentation was maximum at chinese juniper (27.33$\pm$19.44 of emerged adults) followed by Magnolia obovata (8.50$\pm$9.33). Fifty percent of the tested species leaf litters including cherry-tree did not show any augmentation. The adult activities after hibernation were primarily found in May and June at Kwangju and Suwon, and in April at Chungju. The field activity of L. serricome at Suwon was mostly lower than that at other places, except in August at Chungju. The first appearance of L. serricome was observed earlier at Chungju and Kwangju than at Suwon, and the frequency of insect appearance was high in July, August, and September. L. serricome could hibernate by feeding on many kinds of plant leaf litters and it's population could be maintained in the open field in Korea.

The authors studied on the bionomics of the Florida wax scale, Ceroplastes floridensis Comstock and bionomics of two kind of parasites which attack on this Florida wax scale in 1963 to 1964. 1. Ceroplastes floridensis Comstock was heavily infested on the persimmon tree planted in the southern part of Korea, specially at the center of Taegu city. Parasitic ratio of important parasite of Ceroplastes floridensis Comstock, Microterys clauseni was $66.67\%$ and appeared low parasited ratio at the center of the city. 2. The developed eggs of the Ceroplastes floridensis Comstock was appear며 from mid-May to early July. The peak of it was late-May to early June. Average stored eggs inside of a body is 2030. $2030.77\pm0.49.$. 3. The hatching period of the Ceroplastes floridensis Comstock begins from early June to early July. Mid-June was the peak period of it. Pupation period of the male was August 14 to September 7 and adult was emerged on August 20 to September 8. Mean longevity for adult male was 3 days in August but 4 days in September. 4. On the differences of the body- length parasited on the three host plants, persimmon, platanus, and trifoliate orange, the body length parasited on the persimmon was the largest, medium on platanus and the smallest on the trifoliate orange. 5. Microterys clauseni H. Compere parasite on tile Ceroplastes floridensis Comstock with 5 generations in a year. Hibernate in the body of the host as tan·at stage. The first adult appears in middle April. Fifteen days was required for one generation in $21^{\circ}$. The authors observed on the form ovary, female with 6 ovarioles, and mean number of eggs per female was $47.19\pm0.55$. 6. On the parasited individuals of the Microterys clauseni H. Compere a larva was the most numerous and was found 2 individuals or 4 individuals parasite on the one Ceroplastes floridensis Comstock. 7. Coccophagus app. parasited on the only male body of the Ceroplastes floridensis Comstock. The parasitic ratio was $14.831\%$ on persimmon tree in Taegu city.

Four species(25%) of Viperidae(Agkistrodon brevicaudus, Agkistrodon ussuriensis, Agkistrodon saxatilis) and Cloubridae(Rhabdophis tigrenus tigrenus) were Korean poisonous snake. Copulation season of these species was from July to August. Reproduction mode of genus Agkistrodon species was ovoviviparous but Rhabdophis tigrinus tigrinus was the other pattern of oviparous. Optimal movement temperature range was from 20$\circ $C to 29$\circ $C(March~September). Wjen atmosphere temperature was below 10$\circ $C, at that time they hibernate at the ground, rock bottom, stone wall and embankment around the end of a field. The venom of these snakes consist mainly Hematoxin, Cytolysin, Neurotoxin and Cardiotoxin of poisonous liquids. These material injection to animal cause systemic syndrome such as Dizziness(25.7%), Vomitting(23.1%), Fever(22%), Visual trouble(18%), Headace(17.7%), Dyspnoea(17.6%) and bring about other local syndrome such as Discoloration(54.2%), Bleeding(20.2%), Bullae(10.7%) and Skin ulcer(!0.8%). The annual distribution was appeared to decrease 1972 after 1992 and average snakebiting patients was 25.6 per year, but practically total estimated snakebiting was 2,700 per year. The seasonal distribution was most frequent in August(25%), and mortality was 1.8%(26 per 1,430). The sex ratio was 2:1 and according to age distribution, it was most prevalent at one's fifties(19%). The most frequent place where the accident happened was the field(48.2%) and most predilection site of the body for victim were hand(47.8%) and foot(39.5%), Commonly bite snake were Agkistrodon ussuriensis(27.1%), Agkistrodon brevicaudus(22.6%) and Agkistrodon saxatilis(9.6%) but 40.7% of species could not be identified. Treatment of antivenin patient was 75.9% (1,068/1,407).
