  • 등검은메뚜기(EuprepoceRneTmis shirak시 성충에서 면역작용에 관여하는 혈구로 확인된 Plasmatocvte와 granu10cvte 1 딪 granu10cyte 11의 형태와 미세구조적 특징을 광학현미경과 전자현미경을 이용하여 관찰하였다. Plasmatocyte는 방추형 또는 맡은 세포질돌기를 형성하고 있는 다형의 형태로 세포질에는 리소조옴과 식포가 존재하고 있었고, 식포의 융합에 의해서 형성된 multivesicular body가 관찰되었다. Granulocyte 1은 구형의 형태로 세포질에는 약 0.2-0.3 urn 크기의 과립을 함유하고 있었으며, 특히 원형질막 가장자리에 세포의 골격을 유지하는 미세소관 다발을 갖고 있었다. Granulocyte 11는 난형 또는 방추형의 형태로 세포질에는 약 0.5-0.8 Um의 과립이 세포질의 대부분을 차지하고 있었으며, 세포소기 관은 granu10cyte 1보다 덜 발달되어 있었다.

  • 비병원성 세균인 고acirlus subtilis(ATCC6633)를 등검은메뚜기(Euprepocnemis shr'rakii Bolivar)의 성충 복강에 주입한 후, 혈구의 반응양상을 투과전자현미경으로 관찰하였다. 세균에 대한 혈구의 면역반응은 plasmatocyte와 granulocyte에 의한 식 세포작용(phagocytosis)의 형태로 이루어졌으며, 결절형꽁(nodule formation)은 일어나지 않았다. 식 세포작용의 초기 반응은 혈구의 세포질 돌기가 돌출되 면서 이물질을 둘러싼 후, 원형질막과의 융합에 의해 식포가 형성되었고, 식포의 주변부에서는 일차 리소조옴의 집적이 관찰되었으며, 이런 과정은 세균 주입후, 10분 이내에 완료되었다. 일차 리소조옴은 세균 주입 후 1시간 이내에 식포의 한계막과 융합하여 이차 리소조옴을 형성하였으며, 소화된 이물질은 9시간 이내에 exocytosis에 의해 배출 되었다.

  • Studies were carried out to determined the optimal conditions of processing and changes in trypsin indigestible substrate(TIS) and in vitro protein digestibility of paddy grasshopper(Oxya chinensis formosana) under various drying conditions. The multienzyme assy and amino acid compositions were used to predict the quality changes of dried products. The in vitro protein digestidility of defatted products were higher than that of sun and hot air dried products. This results indicated that heat processing is decreased the digestibility, but is increased the TIS contents of dried samples. Amino acid composition of the products was comparable to the ANRC casein scoring pattern. The protein was espeoially low in the amount of lysine, tryptophan and methionine, but high in the quantity of aspartic acid, glutamic acid and arginine indicating that it could be a difference of the dry processing. C-PER and DC-PER were 2.65 and 2.44, respectively, in the defatted and freeze dried products and 2.49 and 2.30, respectively, in hot air dried products. From the these results, it could be confirmed that defatted and freeze dried products might be utilized with feed or foodstuff, unless the toxic substances were no longer detectable.

  • An electron microscopical study on hemocytes of last instar larvae of Orthoptera (Acrida cinerea Thunberg, Paratenodera sinensis De Saussure, Atractomorpha lata Hotschulsk was performed to observe cell types, structures and their origins. Prohemocytes are the smallest round cells with large, nucleus, poorly developed cytoplasmic organelles and lower composition ratio, accouting for less than 1% of all cell types. Little remarked differences were revealed among different species. Plasmatocytes are relatively large cells with higher composition ratio, accounting for 5 to 20%. The majority of the plasmatocytes are oval forms with numerous external cytophismic projections., relatively well developed cytoplasmic organelles. Granular cells are characterized by various granules in cytoplasm. Some considerable remarked differences were revealed among different species. Furthermore the granules themselves differ in fine structures. Adipohemocytes were found only in Acrida cinerea Thunberg.

  • Phytophagous insects were surveyed for biological control of weeds in the southern part of korea from April 20 to July 31, 1987. Phytophagous coleopteran insects representing 12 families, 52 genera and 61 species, hemipteran insects 7 families, 18 genera and 20 species, homopteran insects 4 families, 16 genera and 21 species, hymenopteran insects 2 families, 2 genera and 3 species, and orthopteran 2 familes, 6 genera and 6 species were recorded from 58 weeds. Some chrysomelids and orthopteran insects were potential agents for biological control of weeds.

  • This study was carried out to know the insect fauna of turf grass area in forest. In Korea, graves and public cemetery in mountain areas are usually covered by turf grass which were mainly examined. There were 86 species belonging to 77 genera of 39 families in 11 orders. Among them, site 3 had highest occurrence (38%), second was site 2 (36%) and in the last place was site 1 (26%). Hemiptera revealed best species composition (29.1%) and came Coleoptera (19.8%), Orthoptera (15.1%), Lepidoptera (12.8%) and Odonata (5.8%) etc. The reason why Hemiptera and Orthoptera are mainly found in these areas is because they usually feed on short plants that grow in there. Taxonomic species composition, occurrence ratio by site and species and comparison analysis were provided.

  • Arthropod pests were surveyed from 132 herb species of 121 genera in 50 families of 32 orders at herb garden of Sancheong-gun Agricultural Development Technology Center in Sancheong, Gyeongsangnamdo province from October, 2005 to November, 2006. Ninety eight arthropod pests of 86 genera in 44 families of 9 orders were collected. Although less than 5 arthropod pests were collected from each herb, more than 5 arthropod pests were occurred on Hibiscus mutabililis, Peucedanum japonicum, Aralia cordata, Fraxinus rhynchophylla, Angelica decursiva, Rhaponticum uniflorum, Lonicera japonica, Betula platyphylla and Agrimonia pilosa. Out of collected pests, 98.5% of them damaged leaves of medicinal plants. The highest number of arthropod pests was recorded in May representing 36 species of 32 genera in 20 families of 6 orders. Most of them were collected from less than 5 medicinal plants. However, Atractomorpha lata, Dolycoris baccarum, Myzus persicae, and Nysius plebejus occurred on 42., 22, 20, and 15 medicinal plants, respectively. Atractomorpha lata and Myzus persicae had broad host ranges and seriously damaged. Aphis gossypii was dominant insect pest in May compared with Dolycoris baccarum in June. Atractomorpha lata in August and September, and Myzus persicae in October.
