호박(Cucurbita moschta DUCH)은 한국인들이 즐겨먹는 식용자원으로서 독특한 향미와 약리작용을 갖고 있다. 또한 기후 환경에 대한 적응력이 높고 병해충에도 비교적 강하여 농약사용이 적은 무공해 식품으로 알려져 있다. 호박의 과육에는 혈전증 예방과 두뇌발달에 기여하는 $\alpha$-linoleic acid가 다량 함유되어 있고, 비타민 A의 전구체인 $\beta$-carotene이 풍부하며, 위장이 약한 사람, 회복기의 환자, 부기가 있는 산모에게 좋은 식품으로 애용되어 왔다. 또한 예로부터 호박씨는 독성이 없으므로 어린이, 임산부, 허약자의 조충, 구제약으로 또는 젖이 잘 나지 않을 때에도 많이 쓰여왔다. 그리고 호박꽃은 잎과 함께 식용으로 널리 이용되었을 뿐 아니라 벌레에 물렸거나 상처 난 곳에 으깨어 문지르면 효과가 있어 민간요법으로 사용되어 왔다. 따라서 본 연구에서는 우리나라 전역에서 쉽게 구할 수 있는 호박꽃의 생리활성능을 검색해 봄으로써 천연기능성 식품 소재로의 활용가능성을 제시해 보고자 하였다.

Occurrence pattern of major insect pests on 7 recommended potato cultivars in Korea was investigated from sowing to harvesting time at Kangneung and Daegwallyung experiment fields in 1996. Green peach aphid (Mym persicae Sulzer), potato aphid (Macrosiphum euphorbiae Thomas) and beet armyworm (Spodoptera enigua Hubner) were the major insect pests on potato leaves, and wireworm (Selatosomus puncticollis Mot.) was the major pest on tubers. There was a slight difference of average number of aphids per 50 leaves among cultivars; ranged from 22.7 on cv. Dejima to 46.3 on cv. Superior. Numbers of leaves damaged by beet armyworm larvae on cv. Shepody and cv. Jopung were 11.0 and 14.3, and these cultivars are thought to be resistant against the larvae infestation. However, degree of damage on cv. Dejima and cv. Namsuh was higher 10 times than cv. Shepody and cv. Jopung. In wireworm, the percentage of damaged tubers on cv. Irish Cobbler was lowest of 8.1%, and followed by cv. Superior, cv. Dejima, cv. Jopung, and cv. Atlantic. Whereas, those on cv. Namsuh and cv. Shepody were significantly high of 50.0% and 46.8%.

The present investigation was conducted to provide a systematic approach necessary to establish an integrated insect pest management program of barley in Korea. Some ecological surveys on insect pests of barley have been undertaken at the field of Experimental Station, Ky$\check{o}$ngbuk Provincial Office of Rural Development as a fixed point survey area, and at 23 localities for round survey throughout southern and central Korea from 1983 to 1984. Previously known insects injurious to barley in Korea were revised and the population dynamics of 10 dominant harmful species were analyzed according to either 24 localities or 25 cultivars respectively by using several sampling methods of net sweeping, black light traps, yellow water pan traps and visual counting. As the results, a total of 94 species belonging to 77 genera under 32 families are known to be injurious to barley, among them 20 species are newly added here. In the population density level, the dominant species were disclosed as Laodelphax striatellus (43.1 %), Macrosiphum avenae(27.0 %), Rhopalosiphum padi(6.5 %), R. maidis(5.4 %), Psammolettix strialus(2.7 %), Chlorops oryzae(2.2 %), Agromyza albipennis(2.1 %) Phyllotreta nemorum(1.4 %), Chaetoenema cylindrica(1.0 %), Dolycoris baccarum(1.0 %) in order. For the general abundance of major insect pests, it was highest in the cultivar P'aldal whereas lowest in Milyang #22. There were tendencies that Psammotettix striatus, Dolycoris baccarum, Phyllotreta nemorum and Chaetocnema cylindrica represented a maximum increase in the beginning of June, while Chlorops oryzae and Agromyza albipennis showed in the middle of May but aphids were in the end of May. In the dominance of natural enemies, Nabis stenoferus occupied 21.4 % and Propylaea japonica 9.6 %.

A revised checklist of host plants for 181 species belonging to 103 genera in six subfamilies of Cerambycidae (Coleoptera: Chrysomeloidea) in Korea is provided on the basis of the results of field surveys and literature review. A total of 14 new cerambycid-host associations are confirmed and the Manchurian striped maple, Acer tegmentosum Maxim. (Aceraceae), is listed as a new host of the Asian longhorn beetle, Anoplophora glabripennis (Motschulsky). The names of more than 170 host plants species belonging to 107 genera in 44 families are compiled. Among them, four families (Ulmaceae, Pinaceae, Fagaceae and Betulaceae) are confirmed as the main host families (more than 23%) of most of the cerambycid species. All invalid scientific names and Korean names of plants and cerambycids in the previous literature are corrected in the present paper.

Insect pests damages are increasing on the field of Lycium chinense under environment- friendly management Thus, we was to monitor the occurrence of pests on organic L. chinense in Chungnam Cheongyang and, insecticidal effect of eco-friendly agricultural materials (EFAMs) were tested against major pests. When the buds come out, injury by L. chinense was very high causing the high population density of Myzus persicae in late May and early June, and the injury by Lema decempunctata was increased from mid-June. Otherwise, injuries by Eriophys macrodonis, Henosepilachna vigintioctomaculata and Hedma spp. were continued throughout the growing season. From the fruit held in late July, Hemipteran insects including Plautia stali and Halyomorpba balys were sucking the fruit, and their injury to L. chinense were gradually increased. For the eco-friendly environmental control of M. persicae, L. decempunctata and E. macrodonis, EFAMs containing Sophora flavescens, Melia azedarach (Chinaberry), Chenopodium ambrosioides (Mexican tea), Quassia amara (Amargo), Stemona sessilifolia, Sophora seeds and Nepeta cataria (Catmint), were selected and used to control the insect pests. Control effects of the mixed extract with S. flavescens and Sophora seeds against M. persicae and L. decempunctata were higher than any other EFAM as 84.0% and 86.6%, respectively. In case of E. macrodonis, its control effect was good with the mixed extract with S. flavescens, C. ambrosioides and M. azedarach.

This study was conducted to establish agricultural practices to control diseases and insects for chemical pesticide-free cultivation of leafy vegetables. Two diseases, gray mold(Botrytis cinerea) and soft rot(Erwinia carotovora), on lettuce were reduced by controlling temperature and humidity using air-circulation fan. The aphidophagous lady beetle(Harmonia axyridis) and primary parasitoids(Aphidius colemani) showed activity to control aphids density on Chinese cabbage. Co-application of cooking oil and yolk mixture (COY) and BT(Bacillus thuringiensis) decreased diseases including soft rot(Erwinia carotovora), downy mildew(Peronospora brassicae Gaumann), and powdery mildew(Eryslphe polygoni), and insects such as diamondback moth(Plutella xylostella) and beet armyworm(Spodoptera exigua Hubner). Neem extract treatment reduced downy mildew(Peronospora destructor) on Welsh onion.

To search for the co-relationships between insect-pollinators and the plant species of Asteraceae, insects visiting in flower and the flowers in Korea, were studied from April 2010 to October 2011. The sum of flower visiting degrees are shown 38 in Lepidoptera, 38 in Diptera, 36 in Hymenoptera, and the lowest 6 in Coleoptera, respectively. 65 insect species are identified pollinators, Hymenoptera 13 species(Apidae 11 sp., Formicidae 2 sp.), Lepidoptera 29 species(Pieridae 5sp., Nymphalidae 12 sp., Satyridae 3 sp., Hesperirdae 3 sp., Lycaenidae 2 sp., Danaidae 1 sp., Moth 2 sp.), Diptera 16 species(Tachinidae 1 sp., Syrphidae 12 sp., Muscidae 1sp., Others 2 sp.), and Coleoptera 6 species(Cetoniidae 1 sp., Cermbycidae 3 sp., Chrysomelidae 1 sp., Mordellidae 1 sp.). 31 pollinator species visits the flower of $Erigeron$ $annuus$, next 15 pollinator species does the flower of $Eupatorium$ $japonicum$, and then 13 pollinator species does the flower of $Aster$ $ageratoides$. Only 2 pollinator species visit the flower of $Tephroseris$ $kirilowii$, $Ixeridium$ $dentatum$, $Inula$ $britannica$ var. $japonica$, $Carduus$ $crispus$, $Ligularia$ $fischeri$, $Ainsliaea$ $acerifolia$, $Synurus$ $deltoides$, $Cirsium$ $setidens$, $Crepidiastrum$ $enticulatum$ and $Dendranthema$ $boreale$. Pollinators of Lepidoptera visit more frequently white flower than yellow or purple one. This study found out that mutualisic relations between plants and insect pollinators is carried out in Korea.
