This study was carried out to embody monitoring system of growing environments of fruit tree with Ubiquitous Sensor Network and to analyze various fruit qualities by the tree`s vigor in the apple orchard located in Poonggi-eup, Yeongju-shi, Gyeongsangbukdo, Korea. The tree`s vigor of apple trees was influenced to insolation, temperature, and humidity and it had influence on the weights, sugar contents and the quality(especially in mineral contents) of apples. The use of Ubiquitous Sensor Network will not only contribute to improve the quality of fruit by the offer of scientific fruit-cultivation method, but also to expand its application more and more.

Biological Characteristic of Obolodiplosis robiniae and insecticidal activity of some insecticides against larvae of O. robiniae were investigated. Egg was in oval shape, and its color was light orange and became red when close to hatch. Length of the major axis and the minor axis of egg was 0.4 mm and 0.1 mm, respectively. Larval color was milky and size was 2.6 mm. Pupa was deep brown and its size was about 3.2 mm. Wing and abdomen of adult was black and reddish, respectively. Size of female adult was about 3.3 mm, and larger than male adult. Number of eggs in the ovary was $192.3{\pm}50.7$. First emergence was from late April to late May, and second from late May to late June. Third emergence was from late June to late July. Newly emerged adult escaped from soil, and second and third emerged adult escaped directly from gall of Robinia pseudoacacia leaf. Egg parasitoid was identified as Platygaster robiniae and parasite rate was 51.6%. Among test insecticides, imidacloprid 10% WP and thiacoprid 10% FL showed very strong insecticidal activity against larvae of O. robiniae at 48h later after treatment.

The pine wilt disease is one of the most serious forest diseases that kill the pine trees, and the study on the invasion and movement of the pine wood nematode within the tree is very important for understanding the inhabitation of pine wood nematode. In this relation, the microscopic observation was carried out to study the place of inhabitation and movement of pine wood nematode within the infested wood. In result, the rays were mainly infested by pine wood nematode and showed dark discoloration due to their necrosis in cross, radial and tangential surface. Also, the intensive damage was found in the resin canals. On the other hand, some traumatic resin canals in tangential band were identified in the sapwood near the cambium. In the ray, the pine wood nematode occurred more commonly in the ray parenchyma cell and fusiform ray with horizontal resin canal than in the ray tracheid and uniseriate ray without horizontal resin canal, respectively. The pine wood nematode was thought to move from ray to tracheid through the large natural opening, window-like pit, in the cross-field, neither through the small natural opening, bordered pit, in the tracheid nor through the tracheid wall by creating a bore hole.

본 연구는 최근 대량으로 발생하여 느티나무에 큰 피해를 주고 있는 느티나무벼룩바구미 (Rhynchaenus sanguinipes)의 생활사 및 발육단계별 형태특징을 조사하고 성충의 우화소장 등의 생태적 특성을 파악하여 효율적인 방제를 위한 기초자료를 작성하기 위해 수행되었다. 또한 몇 가지 약제를 공시하여 살충효과 조사를 통해 방제를 위한 기초자료를 수립하였다. 현재까지 느티나무벼룩바구미의 국내 기주식물로서 느티나무만 기재되었으나 본 조사에서 비술나무가 추가되었다. 느티나무벼룩바구미의 유충, 용, 성충의 체장은 각각 4.53$\pm$0.30 mm, 3.30$\pm$0.42 mm, 2.96$\pm$0.12 mm이었다. 월동성충의 출현 시기는 4월 상순부터 4월 하순까지 약 1개월 내외였으며, 신성충 우화기간은 5월 상순부터 5월 하순까지였다. 외부의 기온과 비슷한 20$\pm$에서의 용 발육기간은 약 7.2일이었으며 16$\pm$에서는 10일, 24$\pm$ 5.1일, 28$\pm$ 4.0일로서 기온이 상승함에 따라 발육속도가 빠르게 나타났으며 발육한계온도는 5.8$\pm$이었다. 천적종류는 기생성천적으로서 고치벌류 4종이 조사되었고, 4월 하순부터 우화하기 시작하여 6월 초순에 종료하였다. 페니트로치온, 인독사카브, 에토펜프록스 그리고 치아클로프리드의 느티나무벼룩바구미 성충에 대한 살충활성을 조사한 결과, 모든 약제가 90% 이상의 높은 살충율을 나타내었다. This study was carried out to clarify the biologies and morphological characteristics of Rhynchaenus sanguinipes. Also some chemicals were tested to screen the effective insecticide for the control of the species. Up to date, Zelkova serrata has been hewn as host plant of Rhynchaenus sanguinipes, which shows serious damage in this country. In the present study, Ulmus pumila was first found as host plant in this study. Body lengths of larvae, pupa and adult were 4.53$\pm$0.30 mm, 3.30$\pm$0.42 mm and 2.96$\pm$0.12 mm, respectively. The overwintered adult of the species emerged on early April to late April, and adult of nekt generation emerged on early May to late May, Pupal periods were 10, 7.2, 5.1 and 4 days on 16, 20, 24 and 28$^{\circ}C$, respectively. The lower developmental threshold temperature was 5.8$^{\circ}C$. Four braconid parasitoids were found as natural enemies, which emerged mainly on late April to early June. Insecticidal activities with treatments of fenitrothion 50% EC, indoxacarb 30% WG, ethofenprox 20% EC and thiacloprid 10% SC was investigated against adult of R. sanguinpes, and they showed >90% mortality.

Locust gall midge (LGM), Obolodiplosis robiniae (Haldeman) (Diptera: Cecidomyiidae), is a cecidomyiid insect forming roll-up galls on leaves of Robinia pseudoacacia Linnaeus (Fabaceae). LGM, known as native to North America, was reported from Korea and Japan in 2002. LGM was observed weekly or biweekly to clarify their voltinism and distribution within the crown of the host tree in two sites of Osan and Siheung in Korea from May to August, 2007. Density of LGM was investigated based on the number of larvae per leaf. Two generations of LGM were observed in Siheung site whereas three generations in Osan site during the present study. The result indicated that LGM had at maximum three generations per year. The density of LGM in Osan was higher in the upper crown of the host trees than middle or lower part. In Siheung, LGMs were distributed more on the exterior of the lower crown than the interior. The average number of larvae per gall was $3.3{\pm}0.1$ and $2.8{\pm}0.1$ individuals per leaf in Osan and Siheung, respectively. 아까시잎혹파리(Obolodiplosis robiniae(Haldeman))는 아까시나무(Robinia pseudoacacia Linnaeus(Fabaceae)) 잎 가장자리에 혹을 형성하는 혹파리과 해충으로 북미대륙 동부가 원산으로 국내와 일본에 2002년 유입되었음이 보고되었다. 본 연구는 아까시잎혹파리의 계절별 밀도변동과 수관 내 분포를 구명하기 위하여 수행되었다. 밀도조사는 경기도 오산시 수청동과 시흥시 대야동의 아까시숲에서 5월부터 8월까지 조사되었으며 아까시잎혹파리 밀도는 잎당 유충수를 기준으로 추정되었다. 아까시잎혹파리 세대 수는 지역별로 차이가 있어, 오산에서는 3세대, 시흥에서는 2세대가 관찰되어 국내에서는 최대 3세대가 발생할 수 있음을 보여주었다. 오산지역 아까시나무내 아까시잎혹파리 유충 밀도분포는 수관 상부가 수관 중간 부분과 하부보다 높았다. 시흥지역 아까시나무의 수관 하부 바깥쪽 밀도가 안쪽보다 높았다. 아까시잎혹파리의 혹 당 유충수는 오산, 시흥에서 각각 $3.3{\pm}0.1$, $2.8{\pm}0.1$ 마리였다.

밤나무혹벌 산란동아수의 품종별 차이를 비교한 결과, 석추 및 다압에서 가장 적었고 전체적으로 신초의 하부로 갈수록 산란동아수가 많았으며 특히, 옥광, 축파, 유마 에서 이러한 현상이 뚜렷하였다. 대부분의 품종에서 동아당 평균 1.0개 이상 다중 산란되었으며 신초하부의 경우 산란수가 재래종, 축파, 옥광, 평기에서는 3.0개 이상이었으며 석추와 다압은 1.0개 미만이었다. 산란동아별 난수는 모든 품종에서 상부의 동아에 산란된 난수가 가장 적었고, 하부의 동아에 많은 경향을 보였다. 신초하부의 경우 축파는 산란된 알이 평균 15개 이상으로 가장 많았던 반면, 다압은 한개 이하로 가장 적었다. 품종별 산란비율은 모든 품종에서 밤나무혹벌이 산란한 동아를 발견 할 수 있었으며, 재래종이 $83.8\%$로 가장 높았고, 축파와 유마에서는 각각 78.5와 $75.9\%$ 이상의 산란율을 나타내었다. The number of winter buds oviposited by Drycosmus kuriphilus against chestnut varieties was lower of Ishizuchi and Daap than that of Okkwang, Tsukuba and Arima. D. kuriphilus oviposited multiful eggs in each winter bud of most of the chestnut varieties tested. More than three eggs were oviposited on winter bud of lower shoot of native, Tsukuba, Okkwang and Pyounggi varieties. However, average laid eggs less than one were on winter buds of Tshizuchi and Daap. Number of eggs oviposited in winter bud on lower shoot was higher than those on upper one. More than 15 eggs were oviposited in Tsukuba, whereas one or less egg was oviposited in Daap. Rates of winter buds oviposited by D. kuriphilus in native, Arima and Tsukuba were 83.8, 78.5, and $75.9\%$, respectively.
