In the light of the fact that Cryptorrhynchus lapathy Linne (Coleoptera: Cur-culionidae) is an important past of poplar in korea the Bionomics of the insect were studied to get some basic informations for controlling the insect. The results obtaind are as follows; 1. The poplar and willow borer has one generation in a year overwintering with egg. 2. The pupation stage was from the middle Julne to the middle July. 3. The adult appears from the early July to the middle August. 4. The average length of body of adult was about 8.5cm with female, 7.9cm with male and the length of pupa was about 11.3cm. 5. The average longevities of adults were about 30 days with mate and 40 days with female. 6. The length of damage hole were about 10.3cm. 7. The egg-laying period was from July to August.

A series of experiments was undertaken to learn bionomics and gowt plant resistance of the seedcorn maggot, Delia platura(Meigen), under controlled(24$\pm$$2^{\circ}C$, RH70$\pm$5%, and LD 16:8h)and field conditions. The preoviposition period for the flies was 9 days. The females survived for an average of 50(3-77) and the males for 24(1-59) days. A greater proportion of flies emerged between 6:00 A.M. and 9:00 A.M., soon after the sun rise. After the over-wintering, adults started to emerge in mid-April from pupae located near the soil surface, and peaked in late April by others located deeper. The sex ratio was about 1:1 with total samples of 1,609 females and 1,641 males. Weight of pupae reared from onion was heavier than those from other diets in the laboratory, however its size was samller than that of natural flies. Considerably more eggs were laid near pea seeds than other hosts tested. Among beans, Bapmitkong with blue seed-coat and a cowpea bean strain were preferred for oviposition. 'Namcheon` cultivar was found to be susceptible to attack by the larvae in the laboratory.

At present, 51 textbooks from 6 kinds are adopted at primary and secondary schools in Korea. According to results of content analysis related to soil animals, their bionomics and the ecological roles were mentioned limitedly in only one or two pages. Since mere 7 phyla and 24 kinds of soil animals have been appeared, it is demended that more of subjects concerning soil animals especially in relation to environment should be introduced in school textbooks near in the future.

Experiments were conducted to study on bionomics and control of cutworms; Agrotis tokionis, A. ipsilon, A. fucosa in Suweon, 1978-1979. A. ipsilon and A. fucosa had two or three generations and A. tokionis had one generation a year. A large number of A. toikonis occured at the end of September, and the major peaks of the first generation of A. tokionis and A. fucosa were in mid-June, the second generation in mid-August, and the third generation was at the end of September. These cutworms laid many eggs on the lower surface of curved downward leaf of Chinese cabbage and the larvae later than 3rd instar began to cut the basal part of stem and then pulled into the soil. A parasite of A. tokionis, a braconid wasp, Meteorus rubens, and two unidentified Ichneumnid wasps were found. Mocap and Volaton gave effective control to the cutworms but Volaton should be applied not to contact with plant.

This study was carried out to investigate the bionomics of Ostrinia furnacalis $(Gu\grave{e}n\grave{e}e)$ in the laboratory and field in 1978. The oriental corn borer had three generations a year in Korea ana the first period of moth activity was mostly from early June to early July, the second from mid July to mid August and the third from mid August to early September. It overwintered with larval stage in the corn stubbles. The egg period was 3-4 days. The larva molted 5-6 times and its period was 18-30 days. The longevity of adult was 7-11 days and deposited about 600-800 eggs. An egg parasite and two larval parasites were investigated.

Xylotrechus rusticus (L.) is an important pest of poplars in Korea. The bionomics of the insect were studied to give some scientific bases for a development of the sound control measures. This study was carried out in the field and laboratory during the period from 1968 to 1969. The results ostained are as follows; The gray tiger longicorn has one generation in a year and overwinters as a larva. The adult appears during periods from the middle May to the early July, with peak in the early June and the eggs were laid in a trunk from the early June to the middle July. The mean body length of the adult was 17mm for the male, 21mm for the female and about 20mm for the pupa. The average number of eggs in an ovary were about 172 and about 2mm in length. The larva of the insect feed on the cambium under neath the bark, the diameter of the adult exit hole was about 5-6mm and 5cm in depth.

The Korean Olethreutinae comprises 277 species. In this study, two species of Olethreutinae: Hedya corni Oku, 1974 and Epinotia salicicolana Kuznetzov, 1968, are reported for the first time from Korea. Our records of Hedya corni are based on three specimens in both sexes from Islands Bogildo and Geojedo. The Korean record of Epinotia salicicolana is based on one male specimen from Muan-gun. The present records of Hedya corni represent the first occurrence out of Japan. Hedya corni is similar to Hedya inornata (Walsingham) but differs from the latter in having the reddish brown forewings. Epinotia salicicolana is similar to Epinotia solandriana (Linnaeus) but differs from the latter in having the smaller dorsal patch on the forewing. Habitus and genitalia of the two olethreutine species are illustrated and briefly described. Their bionomics and distribution are summarized. With our new records, the species numbers of the Korean Hedya and Epinotia are increased to 11 and 23, respectively.

The occurrence pattern and bionomics of Selatosomus puncticollis (Motschulsky) were surveyed in three net house (6$\times$70m) in the field and in a laboratory ($20^{\circ}C$, RH$75\%$, L16/DB). Emergence of hibernated adults of S. puncricollis started from early May, reached peak at early June and diminished in late June. Occurrence rate to total number was $42.1\%$ in early June and $31.7\%$ in late May, when most of hibernated adults emerged at these periods. Adults started to oviposit from mid June, and eggs hatched from early July Larvae turned into pupae from mid July and emerged to adults from mid August. Egg-period was 23 days and pupal period was 21 days. It is estimated that preovipositional period and larval period were approximately 10 months and 30 months, respectively. Wireworms were distributed at the soil depth of 10-5 cm, $56.8\%$ in 1997 and $45.8\%$ in 1998. To establish bait techniques to attract wireworms in the soil, six baits: pieces of potato, carrot, and sweet potato, wheat grains, corns, and flour dough wrapped with gauze, were buried at 15 cm of soil depth, and collected after 5 and 10 days. The numbers of wireworms attracted by potato pieces, wheat grains and sweet potato pieces after 10 days were 1.8, 1.6, and 1.4/bait, respectively. Therefore, burying potato pieces at 15 cm of soil depth and collected after 10 days could be recommended as a wireworm baiting technique.
